Firefox不会更改图像源 [英] Firefox won't change image source

问题描述

我正在尝试通过更改元素的src属性来更改JavaScript + Prototype中的图像。它在IE中运行良好，但在Firefox中不行。我没有收到任何错误，脚本在执行此位后继续执行：

I'm trying to change an image in JavaScript+Prototype by changing the "src" attribute of the element. It works fine in IE, but not in Firefox. I don't get any errors and the script continues executing after this bit executes:

var image = $('toggle');
image.setAttribute("src", "../images/icons/icon_minus.gif");
image.setAttribute("alt", "Minus Symbol");
image.setAttribute("title", "Collapse tree");

我做错了什么？如何使浏览器用icon_minus.gif替换现有图像icon_plus.gif？我确定它一定是非常明显的东西，但我无法弄清楚是什么！

What am I doing wrong? How do I make the browser replace the existing image "icon_plus.gif" with "icon_minus.gif"? I'm sure it must be something really obvious but I can't figure out what!

谢谢

推荐答案

无法弄清楚出了什么问题，但我相信它有可能做到：

Cant figure out what is wrong, but I believe its possible to do a:

image.src = "../images/icons/icon_minus.gif";

BTW，图像路径绝对正确吗？

BTW, is the image path absolutely correct?
