这个例子可以接受json数据格式: { total: xxx, page: yyy, records: zzz, rows: [ {name1:”Row01″,name2:”Row 11″,name3:”Row 12″,name4:”Row 13″,name5:”Row 14″}, … 注意java代码中的数据结构格式。
HTML代码举例
<html> <head> <title>jqGrid 实例</title> </head> <body> ···代码省略··· <table id="jsonmap"></table> <div id="pjmap"></div> ···代码省略··· </body> </html>
javascript代码举例
$(function(){ pageInit(); }); function pageInit(){ jQuery("#jsonmap").jqGrid( { url : ctx+'/JSONData', datatype : "json", colNames : [ 'Inv No', 'Date', 'Client', 'Amount', 'Tax','Total', 'Notes' ], colModel : [ {name : 'id',index : 'id',width : 55}, {name : 'invdate',index : 'invdate',width : 90,jsonmap : "invdate"}, {name : 'name',index : 'name asc, invdate',width : 100}, {name : 'amount',index : 'amount',width : 80,align : "right"}, {name : 'tax',index : 'tax',width : 80,align : "right"}, {name : 'total',index : 'total',width : 80,align : "right"}, {name : 'note',index : 'note',width : 150,sortable : false} ], rowNum : 10, rowList : [ 10, 20, 30 ], pager : '#pjmap', sortname : 'id', viewrecords : true, sortorder : "desc", jsonReader : { repeatitems : true, id : "0" }, caption : "JSON Mapping", height : '100%' }); jQuery("#jsonmap").jqGrid('navGrid', '#pjmap', { edit : false, add : false, del : false }); }
java servlet代码举例
