ExtJS添加热键

Question

我想为我的页面添加热键功能。

Ext.onReady(function() { 
    Ext.util.KeyMap(document, { 
     key: 'abc', 
     handler: function() { 
      alert("Hotkey was pressed!"); 
     } 
    }); 
}); 

但事件不会发生。

Answer 1

分机3.3.1：

Ext.onReady(function() { 
    new Ext.KeyMap(document, { 
     key: 'abc', 
     fn: function() { 
      alert("Hotkey was pressed!"); 
     } 
    }); 
}); 

在内线4.0.2.a

：

Ext.onReady(function() { 
    var map = new Ext.util.KeyMap(document,{ 
      //key : "abc" //doesn't work (mybe a bug) 
      key: [65,66,67], // this works, 
      fn: function(){ alert('a, b or c was pressed'); } 
     } 
    ); 
}); 

Answer 2

使用fn键，在PARAMS

不 handler
