SapUI5：如何動態地將按鈕添加到CutomListItem（xml）中？

Question

如何將按鈕動態添加到從oModel獲取數據的自定義列表項中？

XML：

<List items="{msgData>/msgData}" > 
<CustomListItem> 
    <MessageStriptext="{msgData>Text}"></MessageStrip> 


     <List items="{msgData>buttons}"> 
      <CustomListItem> 
       <Button text="{text}" press="onFedYes" class="sapUiTinyMarginEnd"/> 
      </CustomListItem> 
     </List> 


</CustomListItem> 
</List> 

JS：

var oModel = this.fragment.getModel("msgData"); 
     var Buttons = [ 
      {"text": "Apple"}, 
      {"text": "Orange"}, 
      {"text": "Banana"} 
     ]; 

      oModel.oData.msgData.push({ 
       Type : "Information", 
       buttons:Buttons 
      }); 
oModel.refresh(); 

更新的代碼

Answer 1

更新模型代碼看起來應該是這樣

var oModel = this.fragment.getModel("msgData"); 
    var buttons = oModel.getProperty('/msgData/buttons'); 
    buttons.push(<..new button..>); 
    oModel.setProperty('/msgData/buttons', buttons); 

這將重新呈現列表項目與新添加按鈕
