easyui初始化和下拉框

easyUi初始化

$("#tt2").datagrid({
        url: _ctx + '/energyefficiency/queryAllEnergyEfficiency.do',
        pagination: true,
        rownumbers: true,
        fitColumns: true,
        pageSize: DEFAULT_PAGE_SIZE,
        pageList: DEFAULT_PAGE_LIST,
        pageNumber: 1,
        singleSelect: false,
        fit: true,
        loadMsg: "正在加载...",
        rowStyler:function(index,row){
			if ((index+1)%3==0){
				return 'background-color:#F4F4F4;';
			}else{
				return 'background-color:#fff;';
			}
		},
		queryParams: {
			indexName: $.trim($("#index_name").textbox("getValue")),
			indexType: $.trim($("#index_type").textbox("getValue")),
			deptPath:deptPath
        },
        onLoadError: function () {
            jError("查询失败", {
                VerticalPosition: 'center',
                HorizontalPosition: 'center',
                ShowOverlay: false
            });
        }
    });

easyUI下拉框

前台:

$("#indexType").combobox({
		 required: true,
		 url:_ctx +'/energyefficiency/queryIndexTypeSelect.do', //后台获取下拉框数据的url 
		 method:'post',
		 panelHeight:150,//设置为固定高度，combobox出现竖直滚动条
		 valueField:'code',  
         textField:'name',
         multiple:false,
         editable: false
	 });

这里是input标签而不是select

  <input class="easyui-combobox" id="indexType" name="indexType" style="width: 100%" data-options="required:true">

后台方法如下：

 public String queryIndexTypeSelect(String type){
    	String data ;  
        JSONObject json = new JSONObject();  
        JSONArray array = new JSONArray();
        try {
        	 SysDictionary dictionary = new SysDictionary();
        	 //能效指标类型
        	 dictionary.setParentId(type);	
        	 List<Map> energyEfficiencyLst = sysDictionaryServiceImpl.queryDictionaryByParentId(dictionary);
        	 
        	 if(!energyEfficiencyLst.isEmpty()){ 
                    for(Map<String,Object> lb : energyEfficiencyLst){  
                        json.put("code", lb.get("code"));  
                        json.put("name", lb.get("name"));             
                        array.add(json);  
                 } 
        	 }
        	 data =  array.toString();  
		} catch (Exception e) {
			logger.error("{}", e);
			data="{}";
		}
        return data;
    }
