jqGrid的重要选项
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 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 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 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 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 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 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 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 plaincopy to clipboardprint?
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;  
    }  
    public void setSord(String sord) {  
        this.sord = sord;  
    }  
    public String getSidx() {  
        return sidx;  
    }  
    public void setSidx(String sidx) {  
        this.sidx = sidx;  
    }  
    public String getSearch() {  
        return search;  
    }  
    public void setSearch(String search) {  
        this.search = search;  
    }  

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;
}
public void setSord(String sord) {
  this.sord = sord;
}
public String getSidx() {
  return sidx;
}
public void setSidx(String sidx) {
  this.sidx = sidx;
}
public String getSearch() {
  return search;
}
public void setSearch(String search) {
  this.search = search;
}
}

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。
具体的一个实现类:

view plaincopy to clipboardprint?
package cn.gengv.struts2ex.jqGrid;  
import java.util.Collections;  
import java.util.List;  
@SuppressWarnings("serial")  
public class ListContactsAction extends JqGridBaseAction<Contact> {  
      
    private ContactService contactService;  
      
    @Override 
    public String execute() {  
        return this.refreshGridModel();  
    }  
      
    @Override 
    public int getResultSize() {  
        return this.contactService.queryResultsCount();  
    }  
      
    @Override 
    public List<Contact> listResults(int from, int length) {  
        List<Contact> results = Collections.emptyList();  
          
        results = this.contactService.queryByPage(from, length);  
          
        return results;  
    }  
    public void setContactService(ContactService contactService) {  
        this.contactService = contactService;  
    }  
      

package cn.gengv.struts2ex.jqGrid;
import java.util.Collections;
import java.util.List;
@SuppressWarnings("serial")
public class ListContactsAction extends JqGridBaseAction<Contact> {

private ContactService contactService;

@Override
public String execute() {
  return this.refreshGridModel();
}

@Override
public int getResultSize() {
  return this.contactService.queryResultsCount();
}

@Override
public List<Contact> listResults(int from, int length) {
  List<Contact> results = Collections.emptyList();
 
  results = this.contactService.queryByPage(from, length);
 
  return results;
}
public void setContactService(ContactService contactService) {
  this.contactService = contactService;
}

}

而在struts.xml中,应按如下设置配置action:

view plaincopy to clipboardprint?
<action name="jqGrid01" type="json"> 
        <param name="includeProperties"> 
            ^gridModel/[/d+/]/./w+,  
            rows, page, total, record  
        </param> 
        <param name="noCache">true</param> 
        <param name="ignoreHierarchy">false</param> 
    </result> 
</action> 
<action name="jqGrid01" type="json">
  <param name="includeProperties">
   ^gridModel/[/d+/]/./w+,
   rows, page, total, record
  </param>
  <param name="noCache">true</param>
  <param name="ignoreHierarchy">false</param>
</result>
</action>

3.2 客户端(浏览器)

javascript部分:

view plaincopy to clipboardprint?
$(function(){  
    // 配置jqGrid组件  
    $("#gridTable").jqGrid({  
        url: "jqGrid01.action",  
        datatype: "json",  
        mtype: "GET",  
        height: 350,  
        autowidth: true,  
        colModel: [  
              {name:"id",index:"id",label:"ID",width:40},    
              {name:"lastName",index:"lastName",label:"Last Name",width:80,sortable:false},  
              {name:"firstName",index:"firstName",label:"First Name",width:80,sortable:false},  
              {name:"email",index:"email",label:"E-mail",width:160,sortable:false},  
              {name:"telNo",index:"telNo",label:"Tel No",width:120,sortable:false}  
        ],  
        viewrecords: true,  
        rowNum: 15,  
        rowList: [15,50,100],  
        prmNames: {search: "search"},   //(1)  
        jsonReader: {  
            root:"gridModel",       // (2)  
            records: "record",      // (3)  
            repeatitems : false     // (4)  
        },  
        pager: "#gridPager",  
        caption: "联系人列表",  
        hidegrid: false 
    });  
}); 
$(function(){
// 配置jqGrid组件
$("#gridTable").jqGrid({
  url: "jqGrid01.action",
  datatype: "json",
  mtype: "GET",
  height: 350,
  autowidth: true,
  colModel: [
           {name:"id",index:"id",label:"ID",width:40}, 
        {name:"lastName",index:"lastName",label:"Last Name",width:80,sortable:false},
        {name:"firstName",index:"firstName",label:"First Name",width:80,sortable:false},
        {name:"email",index:"email",label:"E-mail",width:160,sortable:false},
        {name:"telNo",index:"telNo",label:"Tel No",width:120,sortable:false}
  ],
  viewrecords: true,
  rowNum: 15,
  rowList: [15,50,100],
  prmNames: {search: "search"}, //(1)
  jsonReader: {
   root:"gridModel",  // (2)
   records: "record",  // (3)
   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:
