EasyUI的TreeGrid的過濾功能的解決思路

function searchROM() {
 var product = $('#Product').combobox('getValue');
 var keytype = $('#keytype').combobox('getValue');
 var keywords = $('#keywords').val();
 var url = encodeURI('/GoodsROM/ROMList?product=' + product + '&keytype=' + keytype + '&keywords=' + keywords+'&'+Math.random());
 $.post(url, {}, function(data) {
 var d = data;//返回json格式結(jié)果
 $('#grid').treegrid('loadData',d);//加載數(shù)據(jù)更新treegrid
 }, 'json');
 }

 loadFilter:function(data){ 
 var newData = new Array();
 var filter = $("#filter").val();
 for(var i=0; i<data.length; i++){ 
 if(data[i].nodeName.indexOf(filter)>0){ 
 // 定義一個數(shù)組 
 newData.push(data[i]); 
 }
 }
 if(newData.length==0){
 return data; 
 }else{
 return newData; 
 }
 },

var allData = new Array();
function doOrgChartInit(idTreeGrid, idMenu, idUriQuery) {
 var bFound = true;

 loadFilter:function(data){ 
 if (bFound&&data[0].nodeName!="Root") {
 allData = data;
 bFound = false;
 }
 return data;
 },
 columns:[
