jqgrid 屬性http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options
一、jqGrid 屬性：
1、datatype：
local 本地
json json數據格式
jsonstring
xml
xmlstring
javascript
function
clientSide
2、width，height：列表寬度/高度
3、colNames（字符串數組，如：['AA','BB']）：
4：colModel 列模式
{name:'', index:'', width:50, sorttype:'int',align:'right', sortable:false}
name:列名
sorttype：排序類型 如：int、float、date等
align 對齊方式： left、right。
sortable 是否可排序：true 、false
5、multiselect 是否可多選 true、false
6、caption 列表標題
7、url 數據請求連接
8、rowNum 顯示行數
9、rowList 列表顯示行數選擇列表
10、viewrecords: true,false 是否顯示記錄總數
11、onSelectRow：選中列表記錄操作
onSelectRow:function(ids) {
}
12、direction 列表文字的排序方向
二、jqgrid 方法：
http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods
######################## 說明：########################
<table id="list"></table>
<div id="pager"></div>
########################################################
#################### 讀取列表屬性或值 ################
1、獲取選中記錄的行號：
var row = jQuery("#list").jqGrid('getGridParam','selrow');
2、根據行號返回選中行的數據
var rowData = jQuery("#list").jqGrid('getRowData', row);
rowData.*** 讀取選中記錄的屬性值“***”未行屬性,如rowData.id,返回行屬性id的值
3、根據行號刪除列表數據
var su=jQuery("#list").jqGrid('delRowData', 12); //刪除行號未12的記錄
4、新增記錄
var datarow = {id:"99",invdate:"2007-09-01",name:"test3",note:"note3",amount:"400.00",tax:"30.00",total:"430.00"};
var su=jQuery("#list").jqGrid('addRowData', 99, datarow); //99未知含義
5、讀取列表請求數據的url
jQuery('#list').jqGrid('getGridParam', 'url'))
6、返回列表的默認排序列
jQuery('#list').jqGrid('getGridParam', 'sortname')
7、返回列表默認的排序方式
jQuery('#list')jqGrid('getGridParam', 'sortorder')
8、返回列表選中記錄
jQuery('#list')jqGrid('getGridParam','selrow')
9、返回列表當前頁序號：
jQuery('#list')jqGrid('getGridParam','page'))
10、返回列表選中記錄數
jQuery('#list').jqGrid('getGridParam','rowNum')
11、返回選中記錄數據類型：
jQuery('#list').jqGrid('getGridParam','datatype')
12、返回列表的記錄數：
jQuery('#list').jqGrid('getGridParam','records')
#################### 設置列表屬性或值 ################
說明：讀取相應的改为set**就能夠設置列表屬性或值.
13、選中某一行記錄
jQuery("#list2").jqGrid('setSelection',"1"); //選中該列表第一行數據
三、ColModel API
http://www.trirand.com/jqgridwiki/doku.php?id=wiki:colmodel_options
建立新的javaweb工程，添加json相關的 jar包。
附上代碼，共以後查考。
Servlet生產json數據格式：
/**
*
*/
package org.rico.demo.jqgrid.demo.dataload;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
/**
* @author rico
* jqgrid 初始列表數據-json數據格式
*/
public class DataLoadByJSon extends HttpServlet {
private static final long serialVersionUID = 5546844758953964549L;
/**
* 說明：網上借來的數據
* 鏈接：http://www.cnblogs.com/jancyxue/archive/2011/08/17/2141676.html
*
*
* jqGrid默認期望返回的json對象格式要求如下：
* {"page":"1","total":"2","records":"13",
* "rows":[
* {id:"1",cell:["1","jancyxue","男","jancyxue@163.com","410958040","江西餘幹"]},
* {id:"2",cell:["2","linda","女","linda@163.com","111111111","湖南"]},
* {id:"3",cell:["3","jason","男","jason@sina.com","222222222","湖北"]},
* {id:"4",cell:["4","lucy","女","lucy@sina.com","33333333","北京"]}
* ]
* }
* 當然，在js中，可以通過jqGrid的jsonReader屬性來修改默認格式
* 我們可以在jsonReader中定義repeatitems : false。這样，可以使用下面的數據格式（为了防止出錯，我們在寫colModel的時候如果實在不會就對應着下面的每個字段寫，就不容易出錯了：
* "rows":[
* {id:"1",engName:"jancyxue",gender:" 男",email:"jancyxue@163.com",QQ:"410958040",address:"江西餘幹"]},
* {id:"2",engName:"linda",gender:" 女",email:"linda@163.com",QQ:"111111111","address:湖南"]},
* {id:"3",engName:"jason",gender:" 男",email:"jason@sina.com",QQ:"222222222",address:"湖北"]},
* {id:"4",engName:"lucy",gender:" 女",email:"lucy@sina.com",QQ:"33333333",address:"北京"]}
* ]
* 就像這样colModel:[{name:'id',index:'id',width:55},{name:'engName',index:'engName',width:100},{name:'gender',index:'gender',width:180, sortable:false},{name:'email',index:'email',width:180},
{name:'QQ',index:'QQ',width:280},{name:'address',index:'address',width:280}]
*
