當樹加載它是偷竊焦點

Question

我有一個在頂部工具欄內有一個文本字段的樹面板。後擊鍵樹重新加載，但它偷焦點遠離文本

這裏是我的代碼：

Ext.define('search_tree', { 
    extend:'Ext.tree.Panel', 
    rootVisible:false, 
    autoScroll:true, 
    store:Ext.create('Ext.data.TreeStore', {   
     root:{ 
      id:'node', 
      nodeType:'async'   
     }, 
     proxy:{ 
      actionMethods:{ 
       'read':'POST' 
      }, 
      type:'ajax',    
      url:'myurl' 
     } 
    }), 

    tbar:['Search:', {  

     xtype:'textfield', 
     id:'search_combo',   
     listeners:{ 
      keyup:{buffer:150,fn:function(field, e) { 
        var val = this.getRawValue(); 

        if(val.length != this.valueLength){ 
         var thisTree = this.up('treepanel'); 
         thisTree.store.getRootNode().removeAll(); 

         //*************** 
         //When this load finishes the focus is taken away 
         //From the text field :(
         //*************** 

         thisTree.store.load({params:{search_string:val}});              
        }          
     }} 
      }  

    }] 
});

一個解決方案是一個回調添加到您的PARAMS上store.load（）來調用重點放在文字上：

//*************** 
//When this load finishes the focus is taken away 
//From the text field :(
//*************** 

thisTree.store.load({params:{ 
    search_string:val, 
    callback: function() { 
     this.focus(); /*or Ext.getCmp('search_combo').focus() depending on scoping*/ 
    } 
}});
