AddEventListener 如何传递函数参数

var EventUtil = new Object;
                EventUtil.addEventHandler = function (oTarget, sEventType, fnHandler) {
                    if (oTarget.addEventListener) {
                        oTarget.addEventListener(sEventType, fnHandler, false);
                    } else if (oTarget.attachEvent) {
                        oTarget.attachEvent("on" + sEventType, fnHandler);
                    } else {
                        oTarget["on" + sEventType] = fnHandler;
                    }
                };
               
                        
                function handleOnblur(div) {
                    
                    alert(div.id);
                }               

　　　　　　var o = function(){
                         var oDiv = document.getElementById("div1");
                        handleOnblur(oDiv);
                    }

                window.onload = function() {
                    var oDiv = document.getElementById("div1");   

                    EventUtil.addEventHandler(oDiv, "blur", o);
                }

可以使用上面这种方式，也可以使用prototype 方式。

  function handleOnblur() {
                    alert(handleOnblur.prototype.addObject);
                }           

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

handleOnblur.prototype.addObject = oDiv;
