我该如何解决这个问题？

Answer 1

对我来说，它的工作后，我有覆盖更多的东西。

Ext.override(Ext.form.field.Base, { 
    initEvents: function() { 
     var me = this, 
     inputEl = me.inputEl, 
      onFieldMutation = me.onFieldMutation, 
      events = me.checkChangeEvents, 
      len = events.length, 
      i, event; 
     if (inputEl) { 
      me.mon(inputEl, Ext.supports.SpecialKeyDownRepeat ? 'keydown' : 'keypress', me.fireKey, me); 
      for (i = 0; i < len; ++i) { 
       event = events[i]; 
       if (event === 'propertychange') { 
        me.usesPropertychange = true; 
       } 
       if (event === 'textInput') { 
        me.usesTextInput = true; 
       } 
       me.mon(inputEl, event, onFieldMutation, me); 
      } 
     } 
     me.callParent(); 
    }, 

    bindPropertyChange: function(active) { 
     var method = active ? 'resumeEvent' : 'suspendEvent', 
      inputEl = this.inputEl; 
     if (this.usesPropertychange) { 
      inputEl[method]('propertychange'); 
     } 
     if (this.usesTextInput) { 
      inputEl[method]('textInput'); 
     } 
    } 
}); 

该部分从版本5.1.1.451复制而来，其中bug已经修复。

Ext.define('Ext.overrides.form.field.ComboBox', { 
    override: 'Ext.form.field.ComboBox', 

    // OVERRIDE 
    checkChangeEvents : Ext.isIE ? 
        ['change', 'propertychange', 'keyup'] : 
        ['change', 'input', 'textInput', 'keyup', 'dragdrop'] 
});
