这个例子展示了一些比较有用的方法，入动态的更改分组，删除分组等。
HTML代码举例
<html> <head> <title>jqGrid 实例</title> </head> <body> ···代码省略··· Group By: <select id="chngroup"> <option value="name">Client name</option> <option value="invdate">Invoice Date</option> <option value="clear">Remove Grouping</option> </select> <br /> <br /> <table id="48remote4"></table> <div id="p48remote4"></div> ···代码省略··· </body> </html>
javascript代码举例
$(function(){ pageInit(); }); function pageInit(){ jQuery("#48remote4").jqGrid({ url:ctx+'/JSONData', datatype: "json", colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'], colModel:[ {name:'id',index:'id', width:55, editable:true, sorttype:'int',summaryType:'count', summaryTpl : '({0}) total'}, {name:'invdate',index:'invdate', width:90, sorttype:'date', formatter:'date', datefmt:'d/m/Y'}, {name:'name',index:'name', width:100}, {name:'amount',index:'amount', width:80, align:"right", sorttype:'number',formatter:'number',summaryType:'sum'}, {name:'tax',index:'tax', width:80, align:"right",sorttype:'number',formatter:'number',summaryType:'sum'}, {name:'total',index:'total', width:80,align:"right",sorttype:'number',formatter:'number', summaryType:'sum'}, {name:'note',index:'note', width:150, sortable:false,editable:true} ], rowNum:10, rowList:[10,20,30], height: 'auto', pager: '#p48remote4', sortname: 'invdate', viewrecords: true, sortorder: "desc", caption:"Dynamically changing the grouping", grouping: true, groupingView : { groupField : ['name'], groupColumnShow : [true], groupText : ['<b>{0}</b>'], groupCollapse : false, groupOrder: ['asc'], groupSummary : [true], groupDataSorted : true }, footerrow: true, userDataOnFooter: true }); jQuery("#chngroup").change(function(){ var vl = $(this).val(); if(vl) { if(vl == "clear") { jQuery("#48remote4").jqGrid('groupingRemove',true); } else { jQuery("#48remote4").jqGrid('groupingGroupBy',vl); } } }); }
