javascript动态添加事件如何加入参数？

JScript code:

var EventUtil = new Object;
EventUtil.addEvent = function(oTarget, sEventType, funName) {
if (oTarget.addEventListener) {//for DOM;
oTarget.addEventListener(sEventType, funName, false);
} else if (oTarget.attachEvent) {
oTarget.attachEvent("on" + sEventType, funName);
} else {
oTarget["on" + sEventType] = funName;
}
};

function loginTab(cv) {alert(cv);}

function addClick() {
var oDiv = document.getElementById("login_title").getElementsByTagName("img");
oDiv[0].style.cursor = "pointer";
EventUtil.addEvent(oDiv[0], "click", [color=#FF0000]loginTab[/color]);}
