event在IE和FF不兼容，今天傳參碰到些問題，參考網上的一些方法，有所心得：
aClassArray[i].onmouseover = function () { //代碼直接寫在里面是可以的，要傳參也可以傳，只是不方便復用 };aClassArray[i].onmouseover =linkMouseover//不傳參的情況下是可以用的，但后續不能用 arguments.callee.caller.arguments[0]aClassArray[i].onmouseover =linkMouseover()//加括號是錯誤用法aClassArray[i].onmouseover = function () { linkMouseover(this) };//this能傳進去，可以alert出來，但evt.clientX + "px"就出問題了，是空的。。。 arguments.callee.caller.arguments[0]//可以用這個解決var src = evt.srcElement || evt.target; //后續還可以跟src===========================================================================
附上練習代碼
