jqGrid与Struts2的结合应用（一） —— 显示基本Grid表格

[/align][align=center][align=left]jqGrid与Struts2的结合应用（一） —— 显示基本Grid表格 [align=left]

                        
                   


                  根据jqGrid的文档，要想生成一个jqGrid，最直接的方法就是：
                  $("#grid_id").jqGrid(options);
                  也就是通过选择符得到一个table的jQuery对象，然后调用jqGrid(options)，得到一个jqGrid对象。

                  重点就在传入的option选项上了，通过这些选项可以得到各种各样的Grid表格。
                  
                  1. jqGrid的重要选项
                  具体的options参考，可以访问jqGrid文档关于option的章节（http://www.trirand.com
                  /jqgridwiki/doku.php?id=wiki:options）。其中有几个是比较常用的，重点介绍一下：
                    url ：jqGrid控件通过这个参数得到需要显示的数据，具体的返回值可以使XML也可以是Json。
                    datatype
                    ：这个参数用于设定将要得到的数据类型。我最常用的是“json”，其余的类型还包括：xml、xmlstring、local、javascript、
                    function。
                    mtype : 定义使用哪种方法发起请求，GET或者POST。
                    height ：Grid的高度，可以接受数字、%值、auto，默认值为150。
                    width
                    ：Grid的宽度，如果未设置，则宽度应为所有列宽的之和；如果设置了宽度，则每列的宽度将会根据shrinkToFit选项的设置，进行设置。

                    shrinkToFit
                    ：此选项用于根据width计算每列宽度的算法。默认值为true。如果shrinkToFit为true且设置了width值，则每列宽度会根据
                    width成比例缩放；如果shrinkToFit为false且设置了width值，则每列的宽度不会成比例缩放，而是保持原有设置，而Grid将会有
                    水平滚动条。
                    autowidth
                    ：默认值为false。如果设为true，则Grid的宽度会根据父容器的宽度自动重算。重算仅发生在Grid初始化的阶段；如果当父容器尺寸变化了，同
                    时也需要变化Grid的尺寸的话，则需要在自己的代码中调用setGridWidth方法来完成。
                    pager ：定义页码控制条Page Bar
                    sortname ：指定默认的排序列，可以是列名也可以是数字。此参数会在被传递到Server端。
                    viewrecords ：设置是否在Pager Bar显示所有记录的总数。
                    caption ：设置Grid表格的标题，如果未设置，则标题区域不显示。
                    caption ：Grid的标题。如果设置了，则将显示在Grid的Header层。
                    rowNum
                    ：用于设置Grid中一次显示的行数，默认值为20。正是这个选项将参数rows（prmNames中设置的）通过url选项设置的链接传递到
                    Server。注意如果Server返回的数据行数超过了rowNum的设定，则Grid也只显示rowNum设定的行数。
                    rowList ：一个数组，用于设置Grid可以接受的rowNum值。例如[10,20,30]。
                    colNames ：字符串数组，用于指定各列的题头文本，与列的顺序是对应的。
                    colModel ：最重要的数组之一，用于设定各列的参数。（稍后详述）
                    prmNames ：这是一个数组，用于设置jqGrid将要向Server传递的参数名称。（稍后详述）
                    jsonReader ：这又是一个数组，用来设定如何解析从Server端发回来的json数据。（稍后详述）
                  1.1 prmNames选项
                  prmNames是jqGrid的一个重要选项，用于设置jqGrid将要向Server传递的参数名称。其默认值为：
                  view plain copy to clipboard print ?
                    prmNames : {  
                        page:"page" ,     // 表示请求页码的参数名称   
                        rows:"rows" ,     // 表示请求行数的参数名称   
                        sort: "sidx" ,  // 表示用于排序的列名的参数名称   
                        order: "sord" ,  // 表示采用的排序方式的参数名称   
                        search:"_search" ,  // 表示是否是搜索请求的参数名称   
                        nd:"nd" ,  // 表示已经发送请求的次数的参数名称   
                        id:"id" ,  // 表示当在编辑数据模块中发送数据时，使用的id的名称   
                        oper:"oper" ,     // operation参数名称（我暂时还没用到）   
                        editoper:"edit" ,  // 当在edit模式中提交数据时，操作的名称   
                        addoper:"add" ,  // 当在add模式中提交数据时，操作的名称   
                        deloper:"del" ,  // 当在delete模式中提交数据时，操作的名称   
                        subgridid:"id" ,  // 当点击以载入数据到子表时，传递的数据名称   
                        npage: null ,   
                        totalrows:"totalrows"   //
                    表示需从Server得到总共多少行数据的参数名称，参见jqGrid选项中的rowTotal   
                    }  
                  view plaincopy to clipboardprint?
                    prmNames : {  
                        page:"page",    // 表示请求页码的参数名称  
                        rows:"rows",    // 表示请求行数的参数名称  
                        sort: "sidx", // 表示用于排序的列名的参数名称  
                        order: "sord", // 表示采用的排序方式的参数名称  
                        search:"_search", // 表示是否是搜索请求的参数名称  
                        nd:"nd", // 表示已经发送请求的次数的参数名称  
                        id:"id", // 表示当在编辑数据模块中发送数据时，使用的id的名称  
                        oper:"oper",    // operation参数名称（我暂时还没用到）  
                        editoper:"edit", // 当在edit模式中提交数据时，操作的名称  
                        addoper:"add", // 当在add模式中提交数据时，操作的名称  
                        deloper:"del", // 当在delete模式中提交数据时，操作的名称  
                        subgridid:"id", // 当点击以载入数据到子表时，传递的数据名称  
                        npage: null,   
                        totalrows:"totalrows" //
                    表示需从Server得到总共多少行数据的参数名称，参见jqGrid选项中的rowTotal  
                    }  
prmNames : {
page:"page", // 表示请求页码的参数名称
rows:"rows", // 表示请求行数的参数名称
sort: "sidx", // 表示用于排序的列名的参数名称
order: "sord", // 表示采用的排序方式的参数名称
search:"_search", // 表示是否是搜索请求的参数名称
nd:"nd", // 表示已经发送请求的次数的参数名称
id:"id", // 表示当在编辑数据模块中发送数据时，使用的id的名称
oper:"oper", // operation参数名称（我暂时还没用到）
editoper:"edit", // 当在edit模式中提交数据时，操作的名称
addoper:"add", // 当在add模式中提交数据时，操作的名称
deloper:"del", // 当在delete模式中提交数据时，操作的名称
subgridid:"id", // 当点击以载入数据到子表时，传递的数据名称
npage: null,
totalrows:"totalrows" // 表示需从Server得到总共多少行数据的参数名称，参见jqGrid选项中的rowTotal
}
                  可以通过这个选项来自定义当向Server发送请求时，默认发送的参数名称。
                  这个参数很重要也很有用，正是通过这个参数，可以方便的改变默认的request的参数，以符合Server端的需要。比如在prmNames中
                  search默认的值为"_search"，这在Struts2的Action中不太方便命名成员变量和getter/
                  setter。因此可以使用 prmNames: {search: 'search'}
                  来改变这一默认值为"search"，这在Struts2的Action对象中就很好设置getter/
                  setter了，即getSearch()和setSearch()。当然其他名字也是可以的。
                  1.2 jsonReader选项
                  jsonReader是jqGrid的一个重要选项，用于设置如何解析从Server端发回来的json数据。其默认值为：
                  view plain copy to clipboard print ?
                    jsonReader : {  
                        root: "rows" ,    // json中代表实际模型数据的入口   
                        page: "page" ,    // json中代表当前页码的数据   
                        total: "total" ,  // json中代表页码总数的数据   
                        records: "records" ,  // json中代表数据行总数的数据   
                        repeatitems: true ,  //
                    如果设为false，则jqGrid在解析json时，会根据name来搜索对应的数据元素（即可以json中
                    元素可以不按顺序）；而所使用的name是来自于colModel中的name设定。   
                        cell: "cell" ,  
                        id: "id" ,  
                        userdata: "userdata" ,  
                        subgrid: {  
                            root:"rows" ,   
                            repeatitems: true ,   
                            cell:"cell"   
                        }  
                    }  
                  view plaincopy to clipboardprint?
                    jsonReader : {  
                        root: "rows",   // json中代表实际模型数据的入口  
                        page: "page",   // json中代表当前页码的数据  
                        total: "total", // json中代表页码总数的数据  
                        records: "records", // json中代表数据行总数的数据  
                        repeatitems: true, //   
                    如果设为false，则jqGrid在解析json时，会根据name来搜索对应的数据元素（即可以json中元素可以不按顺序）；而所使用的name是
                     
                    来自于colModel中的name设定。  
                        cell: "cell",  
                        id: "id",  
                        userdata: "userdata",  
                        subgrid: {  
                            root:"rows",   
                            repeatitems: true,   
                            cell:"cell"  
                        }  
                    }  
jsonReader : {
root: "rows", // json中代表实际模型数据的入口
page: "page", // json中代表当前页码的数据
total: "total", // json中代表页码总数的数据
records: "records", // json中代表数据行总数的数据
repeatitems: true, //
如果设为false，则jqGrid在解析json时，会根据name来搜索对应的数据元素（即可以json中元素可以不按顺序）；而所使用的name是
来自于colModel中的name设定。
cell: "cell",
id: "id",
userdata: "userdata",
subgrid: {
root:"rows",
repeatitems: true,
cell:"cell"
}
}
                  可以这样理解，prmNames设置了如何将Grid所需要的参数传给Server，而jsonReader设置了如何去解析从Server端传回来的json数据。如果没有设置jsonReader的话，jqGrid将会根据默认的设置来解析json数据，并显示在表格里。但如果传回来的json
                  数据，不太符合默认设置（比如内部的结构名不太一样），那么就有必要修改这一设置。比如：
                  view plain copy to clipboard print ?
                    jsonReader: {  
                        root:"gridModel" ,     
                        page: "page" ,     
                        total: "total" ,  
                        records: "record" ,  
                        repeatitems : false   
                    }  
                  view plaincopy to clipboardprint?
                    jsonReader: {  
                        root:"gridModel",     
                        page: "page",     
                        total: "total",  
                        records: "record",  
                        repeatitems : false  
                    }  
jsonReader: {
root:"gridModel",
page: "page",
total: "total",
records: "record",
repeatitems : false
}
                  注1：据其他网友的文章，如果设置repeatitems为false，不但数据可以乱序，而且不用每个数据元素都要具备，用到哪个找到哪个就可以了。实验却是如此。
                  注2：cell、id在repeatitems为true时可以用到，即每一个记录是由一对id和cell组合而成，即可以适用另一种json结构。援引文档中的例子：
                  repeatitems为true时：
                  view plain copy to clipboard print ?
                    jQuery( "#gridid" ).jqGrid({  
                        ...  
                        jsonReader : {  
                            root:"invdata" ,  
                            page: "currpage" ,  
                            total: "totalpages" ,  
                            records: "totalrecords"   
                        },  
                        ...  
                    });  
                  view plaincopy to clipboardprint?
                    jQuery("#gridid").jqGrid({  
                        ...  
                        jsonReader : {  
                            root:"invdata",  
                            page: "currpage",  
                            total: "totalpages",  
                            records: "totalrecords"  
                        },  
                        ...  
                    });  
jQuery("#gridid").jqGrid({
...
jsonReader : {
root:"invdata",
page: "currpage",
total: "totalpages",
records: "totalrecords"
},
...
});
                  json结构为：
                  view plain copy to clipboard print ?
                    {   
                        "totalpages" :  "xxx" ,   
                        "currpage" :  "yyy" ,  
                        "totalrecords" :  "zzz" ,  
                        "invdata"  : [  
                                     {"id"  : "1" ,  "cell"  :[ "cell11" , 
                    "cell12" ,  "cell13" ]},    // cell
                    中不需要各列的name，只要值就OK了，但是需要保持对应   
                                     {"id"  : "2" ,  "cell"  :[ "cell21" , 
                    "cell22" ,  "cell23" ]},  
                                     ...  
                        ]  
                    }  
                  view plaincopy to clipboardprint?
                    {   
                        "totalpages": "xxx",   
                        "currpage": "yyy",  
                        "totalrecords": "zzz",  
                        "invdata" : [  
                                     {"id" :"1", "cell" :["cell11", "cell12",
                    "cell13"]},   //   
                    cell中不需要各列的name，只要值就OK了，但是需要保持对应  
                                     {"id" :"2", "cell" :["cell21", "cell22",
                    "cell23"]},  
                                     ...  
                        ]  
                    }  
{
"totalpages": "xxx",
"currpage": "yyy",
"totalrecords": "zzz",
"invdata" : [
{"id" :"1", "cell" :["cell11", "cell12", "cell13"]}, //
cell中不需要各列的name，只要值就OK了，但是需要保持对应
{"id" :"2", "cell" :["cell21", "cell22", "cell23"]},
...
]
}
                  
                  
                  repeatitems为false时：
                  view plain copy to clipboard print ?
                    jQuery( "#gridid" ).jqGrid({  
                        ...  
                        jsonReader : {  
                            root:"invdata" ,  
                            page: "currpage" ,  
                            total: "totalpages" ,  
                            records: "totalrecords" ,  
                            repeatitems: false ,  
                            id: "0"   
                        },  
                        ...  
                    });  
                  view plaincopy to clipboardprint?
                    jQuery("#gridid").jqGrid({  
                        ...  
                        jsonReader : {  
                            root:"invdata",  
                            page: "currpage",  
                            total: "totalpages",  
                            records: "totalrecords",  
                            repeatitems: false,  
                            id: "0"  
                        },  
                        ...  
                    });  
jQuery("#gridid").jqGrid({
...
jsonReader : {
root:"invdata",
page: "currpage",
total: "totalpages",
records: "totalrecords",
repeatitems: false,
id: "0"
},
...
});
                  json结构为：
                  view plain copy to clipboard print ?
                    {   
                        "totalpages"  :  "xxx" ,   
                        "currpage"  :  "yyy" ,  
                        "totalrecords"  :  "zzz" ,  
                        "invdata"  : [  
                                     {"invid"  :  "1" , "invdate" : "cell11" , 
                    "amount"  : "cell12" ,  "tax"  : "cell13" ,  "total"  :
                    "1234" ,  "note"  : "somenote" },  // 数
                    据中需要各列的name，但是可以不按列的顺序   
                                     {"invid"  :  "2" , "invdate" : "cell21" , 
                    "amount"  : "cell22" ,  "tax"  : "cell23" ,  "total"  :
                    "2345" ,  "note"  : "some note" },  
                                     ...  
                        ]  
                    }  
                  view plaincopy to clipboardprint?
                    {   
                        "totalpages" : "xxx",   
                        "currpage" : "yyy",  
                        "totalrecords" : "zzz",  
                        "invdata" : [  
                                     {"invid" : "1","invdate":"cell11", "amount"
                    :"cell12",   
                    "tax" :"cell13", "total" :"1234", "note" :"somenote"}, //   

                    数据中需要各列的name，但是可以不按列的顺序  
                                     {"invid" : "2","invdate":"cell21", "amount"
                    :"cell22",   
                    "tax" :"cell23", "total" :"2345", "note" :"some note"},  
                                     ...  
                        ]  
                    }  
{
"totalpages" : "xxx",
"currpage" : "yyy",
"totalrecords" : "zzz",
"invdata" : [
{"invid" : "1","invdate":"cell11", "amount" :"cell12",
"tax" :"cell13", "total" :"1234", "note" :"somenote"}, //
数据中需要各列的name，但是可以不按列的顺序
{"invid" : "2","invdate":"cell21", "amount" :"cell22",
"tax" :"cell23", "total" :"2345", "note" :"some note"},
...
]
}
                  2. colModel的重要选项

                  和jqGrid一样colModel也有许多非常重要的选项，在使用搜索、排序等方面都会用到。这里先只说说最基本的。
                    name ：为Grid中的每个列设置唯一的名称，这是一个必需选项，其中保留字包括subgrid、cb、rn。
                    index
                    ：设置排序时所使用的索引名称，这个index名称会作为sidx参数（prmNames中设置的）传递到Server。
                    label
                    ：当jqGrid的colNames选项数组为空时，为各列指定题头。如果colNames和此项都为空时，则name选项值会成为题头。

                    width ：设置列的宽度，目前只能接受以px为单位的数值，默认为150。
                    sortable ：设置该列是否可以排序，默认为true。
                    search ：设置该列是否可以被列为搜索条件，默认为true。
                    resizable ：设置列是否可以变更尺寸，默认为true。
                    hidden ：设置此列初始化时是否为隐藏状态，默认为false。
                    formatter
                    ：预设类型或用来格式化该列的自定义函数名。常用预设格式有：integer、date、currency、number等（具
                    体参见文档 ）。
                  3. 第一个实例
                  3.1 服务器端
                  用于提供数据的Action。为了可以复用这种专门接受jqGrid传来参数的Action，我抽象出一个基本类。具体代码如下：
                  view plain copy to clipboard print ?
                    package  cn.gengv.struts2ex.jqGrid;  
                       
                    import  java.util.Collections;  
                    import  java.util.List;  
                    import  com.opensymphony.xwork2.ActionSupport;  
                       
                    @SuppressWarnings ( "serial" )  
                    public   abstract   class  JqGridBaseAction<T>  extends 
                    ActionSupport {  
                        // 和jqGrid组件相关的参数属性   
                        private  List<T> gridModel = Collections.emptyList();  
                        private  Integer rows =  0 ;  
                        private  Integer page =  0 ;  
                        private  Integer total =  0 ;  
                        private  Integer record =  0 ;  
                        private  String sord;  
                        private  String sidx;  
                        private  String search;  
                       
                        public   abstract   int  getResultSize();  
                       
                        public   abstract  List<T> listResults( int  from,  int 
                    length);  
                       
                        public  String refreshGridModel() {  
                            try  {  
                                List<T> results = Collections.emptyList();  
                                record = this .getResultSize();  
                                int  from = rows * (page -  1 );  
                                int  length = rows;  
                                results = this .listResults(from, length);  
                                this .setGridModel(results);  
                                total = (int ) Math.ceil(( double ) record / (
                    double ) rows);  
                                return  SUCCESS;  
                            } catch  (Exception e) {  
                                e.printStackTrace();  
                                this .addActionError(e.getMessage());  
                                return  ERROR;  
                            }  
                        }  
                       
                        public  List<T> getGridModel() {  
                            return  gridModel;  
                        }  
                        public   void  setGridModel(List<T> gridModel) {  
                            this .gridModel = gridModel;  
                        }  
                        public  Integer getRows() {  
                            return  rows;  
                        }  
                        public   void  setRows(Integer rows) {  
                            this .rows = rows;  
                        }  
                        public  Integer getPage() {  
                            return  page;  
                        }  
                        public   void  setPage(Integer page) {  
                            this .page = page;  
                        }  
                        public  Integer getTotal() {  
                            return  total;  
                        }  
                        public   void  setTotal(Integer total) {  
                            this .total = total;  
                        }  
                        public  Integer getRecord() {  
                            return  record;  
                        }  
                        public   void  setRecord(Integer record) {  
                            this .record = record;  
                        }  
                        public  String getSord() {  
                            return  sord;  
                        }

                  说明：
                    其中的成员变量对应着jqGrid的prmNames和jsonReader中的设置。
                  
                        成员变量 对应 prmNames 对应 jsonReader 注释
                        rows rows - 每页中现实的记录行数
                        search search - 是否是用于查询的请求
                        sidx sort - 用于排序的列名
                        sord order - 排序的方式
                        page page page 当前页码
                        gridModel - root 用于得到实际数据的数组名称
                        total - total 总页数
                        record - records 总记录数

                  
                    refreshGridModel()方法中，主要工作就是为gridModel、record、total赋值，这些值也将会传回客户端。

repeatitems : false // (4)
},
pager: "#gridPager",
caption: "联系人列表",
hidegrid: false
});
});
                  其中主要的选项在开头已经介绍过了，另外需要说明以下几点：
                  1、在位置(1)处，为了配合Server端的Action类中的成员变量命名，将prmNames中search对应的“_search”更改为
                  “search”。
                  2、在位置(2)(3)处，为了配合Server端的Action类中的成员变量命名，将jsonReader中root对应的“rows”更改为
                  “gridModel”，将records对应的“records”更改为“record”。
                  在后面的request和response解析中，就可以看到这些更改的作用。
                  html部分：
                  要想顺利的使用jqGrid，需要想页面中引入6个文件，其中4个js文件，2个css文件。它们分别是：
                    jquery-ui-1.8.1.custom.css（jQuery UI界面的CSS文件）
                    ui.jqgrid.custom.css（专用于jqGrid界面的CSS文件）
                    jquery-1.4.2.min.js（jQuery的核心）
                    jquery-ui-1.8.1.custom.min.js（用于支持jQuery UI界面）
                    grid.locale-zh-CN.js（针对jqGrid的locale设置，根据locale不同，选择不同的尾缀）
                    jquery.jqGrid.min.js（jqGrid的核心，可以到jqGrid网站，根据需求选择模块下载）

                  注 ：jqGrid的官方包中原本针对中文的locale
                  js文件是grid.locale-cn.js，但是里面的某些设置，并没有做到完全中文化，因此我从Struts2-jQuery插件中分离出
                  grid.locale-zh-CN.js和jquery.ui.datepicker-zh-CN.min.js这两个文件以备后用。说起来这两个文件中，针对中文的设置还是不错的。


                  引入这6个文件后，创建jqGrid的工作就交给上面写的javascript代码来完成了。

                  HTML中的代码，异常简洁。
                  3.3 整个流程


                  通过Firebug监测request和response就可以看出Server和浏览器之间的数据交互。当打开页面的时候，jqGrid初始化，会向Server发送url中定义的request，并传递参数。如下：
                  http://localhost:8085/Hare/jqGridTest/jqGrid01.action?search=false&nd=1278331032140&rows=15&page=1&sidx=&sord=asc

                  jqGrid会根据prmNames中的定义，向Server传递参数，例如将jqGrid选项中rowNum的值，作为参数rows传递到
                  Server。

                  由于我将prmNames中的search设为“search”，所以参数里表中出现了这个参数；否则仍会根据原来的默认值，出现“_search”参数。


                  再看看response，Server发送来的json数据，格式是这样的：

                  jqGrid根据jsonReader中的设置，解析json数据。根据jsonReader中的root（我设置的是“gridModel”），得到数据记录数组；根据rows得到每页显示的行数；根据page设置当前页数；根据records（我设置的是“record”）得到所有记录数量；根据total得到所有页数。


                  由此，jqGrid完成一个request，并将得到的response，解析为所需的数据，显示到Grid表格中。
