div注册鼠标事件 疑问

Question

DivDialog = Class.create();DivDialog.construct = function($self,$class){
    this.initialize = function() 
{
              _div = document.createElement("div");
              var that = this;
              _div.onMouseDown = that.getDown;
        }

this.getDown = function(event)
{
if(window.event.button==2)
                {
                       alert("右键点击");
                 }
}
}我给 _div 注册了鼠标事件，但是为什么没有效果，是我写错了吗

Answer 1

重新贴一遍，有点错误
DivDialog = Class.create();DivDialog.construct = function($self,$class){
    var _div = null; 
   
    this.initialize = function() 
{
              _div = document.createElement("div");
              var that = this;
              _div.onMouseDown = that.getDown
        }

this.getDown = function(event)
{
if(window.event.button==2)
                {
                       alert("右键点击");
                 }
}
}
