这是一个双击事件，双击easyui表单的任意任意一行，弹框出现子表的数据信息。接下来就是详细实现：
$(function(){
$("#wyfeeGrid").datagrid({
onDblClickRow:function(index,row){
var orderNum = row.orderNum;
var wyfeeDetailGrid = GridE.init($("#wyfeeDetailGrid"),{
url : DOMAIN_URL + "/wyfeeDetail/getWyfeeDetailVoByOrderNum.do?orderNum="+orderNum,
isField : "id",
pagination:false,
pageNumber:1,
});
var title = "缴费明细表";
$('#detailDlg').dialog('open').dialog('setTitle',title);
}
});
});
