Question

我需要在ajax呼叫成功时更新 sencha 模板。样本代码如下

Ext.define( casta.view.Intro , {
    extend:  Ext.tab.Panel ,
    tpl:  <p> {username} </p> ,
    initComponent: function(){
        //Be sure to use the var keyword for planet earth, otherwise its declared as a global variable
        //var planetEarth = { name: "Earth", mass: 1.00 };
       //this.setHtml(this.getTpl().apply(planetEarth));
         Ext.Ajax.request( 
        {    
            waitMsg:  Bitte warten... , 
            url:  http://localhost:8000/api/casta/user/?format=json , 

            success:function(response,options){ 
                //var responseData = Ext.util.JSON.decode(response.responseText); 
                  this.setHtml(this.getTpl().apply(response.responseText));
            }                       
        } 
        ); 
    }
});

错误控制台

this.getTpl is not a function
[Break On This Error]   

this.setHtml(this.getTpl().apply(response.responseText));

在 sucess i 上,我需要更新模板,但问题在于此。 getTpl in unfreed in in in inline 函数 sucess: fope 。它定义在 init party 之后。我需要在 sucess 中调用。有什么想法吗?

它不是真正的父母。你不能旅行到DOM得到它,但是...

Ext.define( casta.view.Intro , {
    extend:  Ext.tab.Panel ,
    tpl:  <p> {username} </p> ,
    initComponent: function(){
        //Be sure to use the var keyword for planet earth, otherwise its declared as a global variable
        //var planetEarth = { name: "Earth", mass: 1.00 };
       //this.setHtml(this.getTpl().apply(planetEarth));
       var me = this;
         Ext.Ajax.request( 
        {    
            waitMsg:  Bitte warten... , 
            url:  http://localhost:8000/api/casta/user/?format=json , 

            success:function(response,options){ 
                //var responseData = Ext.util.JSON.decode(response.responseText); 
                  me.setHtml(me.getTpl().apply(response.responseText));
            }                       
        } 
        ); 
    }
});

去查查关闭情况吧
