支持多种类型的数据集合作为数据源

　　jqGrid可以绑定三种类型的数据:XML,JSON和数组。使用不同的数据类型主要是设置datatype属性,它的值分别为'xml','json','local'(数组)

$("#grid1").jqgrid(
........
datatype: "xml",
........
);

　　下面则列举各种数据类型的格式

　　XML格式：　

<rows>
<page></page>
<total></total>
<records></records>
<row id="rowid">
<cell>value1</cell>
.........
<cell>valueN</cell>
</row>
</rows>

　　json格式

{"page":"页号","rows":[{name1:'value1',name2:'value2',.....nameN:'valueN'},.... {....} ], "total":记录数,"records":总记录数}

　　数组格式

var datas=[
{name1:'value1',name2:'value2',..... nameN:'valueN'},
.... 
{....} 
];
//把数据添加到jqgrid里
for (var i = 0; i <= mydata.length; i++) {
jQuery("#grid1").jqGrid('addRowData', i + 1, mydata[i]);
}

或者设置data属性

$("#grid1").jqgrid(
......
data:mydata,　　　　datatype:'local',
.......
);

统计运算的功能

　　将footerrow设为true,绑定gridComplete事件。

$("#grid1").jqgrid(......
footerrow: true,
gridComplete: completeMethod,
.......);
function completeMethod()
{
var sum_amount=$("#grid1").getCol('amount',false,'sum');
var sum_tax=$("#grid1").getCol('tax',false,'sum');
var sum_total=$("#grid1").getCol('total',false,'sum');
$("#grid1").footerData('set', { name: '合计:', amount: sum_amount, tax: sum_tax, total: sum_total });
}

　　统计时利用getCol方法，第一个参数为colMode的name值，第二个设为false，否则会返回一个数组而不是但一个数据，第三个是设置统计方式，有'sum','avg'和'count'。

排序

　　只要单击列的标题，就可以对该列进行升序或降序的排序。设置该列是否允许排序，在列的属性里设置sortable，同时对于不同的数据类型，也需要设置其相应的排序类型sorttype，类型有int/integer 整型,float/number/currency 浮点型，date 日期，text 文本，function 定义函数来实现自定的排序规则。

$("#grid1").jqgrid( ........
colModel: [
.........
{ name: 'id', index: 'id', width: 60, myexport: true, editable: true , sorttype: "int", sortable: true},
.............
],
........);

分组

var mydata = [
{id:"1",invdate:"2010-05-24",name:"test",note:"note",tax:"10.00",total:"2111.00"} ,
{id:"2",invdate:"2010-05-25",name:"test2",note:"note2",tax:"20.00",total:"320.00"},
{id:"3",invdate:"2007-09-01",name:"test3",note:"note3",tax:"30.00",total:"430.00"},

{id:"21",invdate:"2007-10-01",name:"test",note:"note",amount:"200.00",tax:"10.00",total:"210.00"},
{id:"22",invdate:"2007-10-02",name:"test2",note:"note2",amount:"300.00",tax:"20.00",total:"320.00"},

];
jQuery("#list48").jqGrid({
data: mydata,
datatype: "local",
height: 'auto',
rowNum: 30,
rowList: [10,20,30],
colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'],
colModel:[
{name:'id',index:'id', width:60, sorttype:"int"},
{name:'invdate',index:'invdate', width:90, sorttype:"date", formatter:"date"},
{name:'name',index:'name', width:100, editable:true},
{name:'amount',index:'amount', width:80, align:"right",sorttype:"float", formatter:"number", editable:true},
{name:'tax',index:'tax', width:80, align:"right",sorttype:"float", editable:true}, 
{name:'total',index:'total', width:80,align:"right",sorttype:"float"}, 
{name:'note',index:'note', width:150, sortable:false} 
],
pager: "#plist48",
viewrecords: true,
sortname: 'name',
grouping:true,
groupingView : {
groupField : ['name']
},
caption: "Grouping Array Data"
});

还有复杂一点的排序，那还是上jqGrid Demos看看吧！

筛选

　　jqGrid的筛选并不是在grid里面的内容进行筛选，其实是对数据库里的数据筛选查询。

　　html:

<table id="s2list"></table>
<div id="s2pager"></div>

　　javascript:

jQuery("#s3list").jqGrid('navGrid','#s3pager',{edit:false,add:false,del:false,search:false,refresh:false}); jQuery("#s3list").jqGrid('navButtonAdd',"#s3pager",{caption:"Toggle",title:"Toggle Search Toolbar", buttonicon :'ui-icon-pin-s', 　　　　onClickButton:function(){　　　　　　 mygrid[0].toggleToolbar() 　　}});jQuery("#s3list").jqGrid('navButtonAdd',"#s3pager",{caption:"Clear",title:"Clear Search",buttonicon :'ui-icon-refresh',　　　　 onClickButton:function(){ 　　　　　　mygrid[0].clearToolbar() 　　}}); jQuery("#s3list").jqGrid('filterToolbar');

增删改查工具栏及分页栏

　　jqGrid附带了分页栏，在分页栏上可以添加增加，修改，删除以及查询按钮。

　　在html多添加一个层，这个层就存放分页栏：

<div id="pager"></div>
$("#grid1").jqgrid(
......
pager:"#pager",　　　　　//通过这属性还可以设置可选的页面大小　　　　 rowList: [10, 20, 30],
.......
);//这里的 edit,add等就是对应编辑新增等按钮，通过设置布尔值来决定是否显示
jQuery("#grid1").jqGrid('navGrid', '#pager', { edit: true, add: true, del: true, search: true, refresh: true});//或者用这种形式 
　　jQuery("#grid1").jqGrid('navGrid', '#pager',
　　　　{}, //options
　　　　{height: 280, reloadAfterSubmit: false }, // edit options
　　　　{height: 280, reloadAfterSubmit: false }, // add options
　　　　{reloadAfterSubmit: false }, // del options
　　　　{} // search options
　　);
