window.DEvent 
   
     =
   
      {
 addListener:
   
     function
   
     (obj,target,act){
 
   
     if
   
     (obj.attachEvent)
 obj.attachEvent(
   
     "
   
     on
   
     "
   
      
   
     +
   
      target , act);
 
   
     if
   
     (obj.addEventListener)
 obj.addEventListener(target , act , 
   
     false
   
     );
 }
 removeListener:
   
     function
   
     (obj,target,act){
 
   
     if
   
     (obj.detachEvent)
 obj.detachEvent(
   
     "
   
     on
   
     "
   
     +
   
     target,act);
 
   
     if
   
     (obj.removeEventListener)
 obj.removeEventListener(target,act,
   
     false
   
     );
 } 
}
  
    

  
    

   
     Object.prototype.eventHandler 
   
     =
   
      
   
     function
   
     (handler){
 
   
     var
   
      b 
   
     =
   
      
   
     this
   
      ;
 b 
   
     =
   
      b;
 
   
     return
   
      
   
     function
   
     (c){
 
   
     if
   
     (
   
     !
   
     c){
 c 
   
     =
   
      window.event ;
 }
 
   
     if
   
     (c
   
     &&!
   
     c.target){
 c.target 
   
     =
   
      c.srcElement; 
 }
 b[handler](c);
 } 
}
  
    

调用方法如下：

  
    

   
     function
   
      test(){

   
     var
   
      container 
   
     =
   
      document.getElementById(
   
     "
   
     div1
   
     "
   
     );

   
     this
   
     .container.onmouseMove 
   
     =
   
      
   
     this
   
     .eventHandler(
   
     "
   
     onMouseMoveMouse
   
     "
   
     );
  
    
  
    

   
     CEvent.addListener(this.container, "mousemove", this.eventHandler("onmapmousemove"));
}
  
    

onMouseMoveMouse.js

  
    

   
     Zx.prototype.onmapmousemove 
   
     =
   
      
   
     function
   
     (evt) {

   
     /*
   
     var cpointtmp = new ZxPoint(this.container.offsetLeft + evt.clientX - this.mapDiv.offsetLeft, this.container.offsetTop + evt.clientY - this.mapDiv.offsetTop);
 Theodolite$setPoint(cpointtmp);
   
     */
   
     
alert(
   
     "
   
     test
   
     "
   
     );
 }
