JS不在Firefox中工作，适用于IE和Chrome

标签： javascript firefox

想知道是否有人可以提供一些见解，为什么这个js在Firefox中不起作用但是在IE和Chrome下完全正常工作？

当鼠标悬停在页面顶部的某些按钮上时，它会改变很多div的颜色。

可在我的网站上看到：ptable.info 

window.onload=function(){
var noblegasesColl = document.getElementsByClassName('noblegases');
var halogensColl = document.getElementsByClassName('halogens');
var othernonmetalsColl = document.getElementsByClassName('othernonmetals');
var transitionmetalsColl = document.getElementsByClassName('transitionmetals');
var metalloidsColl = document.getElementsByClassName('metalloids');
var posttransitionColl = document.getElementsByClassName('posttransition');
var alkalineColl = document.getElementsByClassName('alkaline');
var alkaliColl = document.getElementsByClassName('alkali');
var actinoidsColl = document.getElementsByClassName('actinoids');
var lanthanoidsColl = document.getElementsByClassName('lanthanoids');

答案 0 :(得分：1)

您必须使用style.backgroundColor或style['backgroundColor']来设置背景颜色。这些方法中的任何一种都应该适用于浏览器。我已经在FireFox 23，Opera 15，Chrome 31（Dev Build）和IE10中进行了测试。

您可以参考here获取样本小提琴。小提琴有三个div，id分别为aa，bb和cc。

当您执行mouseover和mouseout时，您会发现它会影响Chrome，IE10和Opera中的所有三个div。但在FireFox中，它仅影响第一个和第三个div，因为第二个div使用style['background-color']而FireFox无法识别。
