javascript event在FF和IE的兼容传参心得(绝对好用)

event在IE和FF不兼容,今天传参碰到些问题,参考网上的一些方法,有所心得:
aClassArray[i].onmouseover = function () { //代码直接写在里面是可以的,要传参也可以传,只是不方便复用 }; aClassArray[i].onmouseover =linkMouseover//不传参的情况下是可以用的,但后续不能用 arguments.callee.caller.arguments[0] aClassArray[i].onmouseover =linkMouseover()//加括号是错误用法 aClassArray[i].onmouseover = function () { linkMouseover(this) };//this能传进去,可以alert出来,但evt.clientX + "px"就出问题了,是空的。。。 arguments.callee.caller.arguments[0]//可以用这个解决 var src = evt.srcElement || evt.target; //后续还可以跟src
