自定义组件时，这个设置的data的值在运行时怎么读取？

棒棒糖

                        var me = this;
                        me.callParent(value, bindingContext);
                        var cfg = this._processCfg();
                        //组件初始化之前操作
                        //this.fireEvent('onBeforeInit',{source:this,settings:cfg});               
                        debugger;
                        me.dataComp = me.getModel().comp(me.data);

那要看自己是否定了js方法去获取

不知道该怎么读取这个data参照了select控件类

jishuang

select的可以这样获取this.comp("select9").options.owner.xid

1.     <div component="$UI/system/components/justep/data/data" autoLoad="true"
   
2.       xid="treeData" idColumn="id">
   
3.       <column label="主键" name="id" type="Number"/>  
   
4.       <column label="父节点的ID" name="pId" type="Number"/>  
   
5.       <column label="节点名称" name="name" type="String"/>  
   
6.       <column label="节点是否展开" name="open" type="Boolean"/>  
   
7.       <column label="打开时的图标" name="iconOpen" type="Boolean"/>  
   
8.       <column label="关闭时的图标" name="iconClose" type="Boolean"/>  
   
9.       <column label="默认的图标" name="icon" type="Boolean"/>  
   
10.       <data xid="default1">[ { id:1, pId:0, name:"父节点1", title:"", checked:true, open:true}, { id:11, pId:1, name:"父节点11", title:"", checked:true}, { id:111, pId:11, name:"叶子节点111", title:"", checked:true, isHidden:true}, { id:112, pId:11, name:"叶子节点112", title:""}, { id:113, pId:11, name:"叶子节点113", title:""}, { id:12, pId:1, name:"父节点12", title:"", isHidden:true}, { id:121, pId:12, name:"叶子节点121", title:""}, { id:122, pId:12, name:"叶子节点122", title:"", isHidden:true}, { id:123, pId:12, name:"叶子节点123", title:""}, { id:2, pId:0, name:"父节点2", title:""}, { id:21, pId:2, name:"父节点21", title:"", isHidden:true}, { id:211, pId:21, name:"叶子节点211", title:""}, { id:212, pId:21, name:"叶子节点212", title:""}, { id:213, pId:21, name:"叶子节点213", title:""}, { id:22, pId:2, name:"父节点22", title:""}, { id:221, pId:22, name:"叶子节点221", title:""}, { id:222, pId:22, name:"叶子节点222", title:""}, { id:223, pId:22, name:"叶子节点223", title:""} ]</data>
    
11.     </div>

.w页面的html片段如上面所示,我要在运行时的JS，init方法中读取到上面绑定的treedata的值，怎么获取？

1.                 // 初始化
   
2.                 init : function(value, bindingContext) {
   
3.                         var me = this;
   
4.                         me.callParent(value, bindingContext);
   
5.                         var cfg = this._processCfg();
   
6.                         //组件初始化之前操作
   
7.                         //this.fireEvent('onBeforeInit',{source:this,settings:cfg});               
   
8.                         debugger;
   
9.                         me.dataComp = me.getModel().comp(me.data);

上面的获取方式不能，督导div绑定的data，我该怎么拿到这个treedata的值呢？

参考/UI2/system/components/justep/gridSelect/gridSelect.js中
_getOptionData的实现
