javascript代码 不兼容IE以外浏览器
js代码如下：

在IE下运行良好，其他浏览器不行，怎么回事？我只有50分，麻烦了
或者提供一个效果一样的也可以，效果要完全一样的，包括图片的排列方式，谢了
这种写法在非IE下是不正确的。
应改为$('main_img').setAttribute("src",this.getAttribute("rel"));
function change(){
var thumbs = document.getElementsByClassName('thumb_img');
for (var i=0; i<thumbs.length; i++) {
thumbs[i].onmouseover = function () {$('main_img').setAttribute("src",this.getAttribute("rel")); $('main_img').setAttribute("link",this.getAttribute("link"));};
thumbs[i].onclick = function () {location = this.getAttribute("link");}
}
另外，你这种写法，执行起来还是有小问题，会导致鼠标第一次碰到图片的时候没反应。
应该在页面加载的时候，先调用一次change();然后两个img里的onmouseover事件可以不要了。
