动态更改图像的 JavaScript 代码适用于 IE 而不是 FF、Chrome 等:(

发布于 2024-12-05 00:54:53 字数 15367 浏览 1 评论 0原文

通常我听说代码在 IE 之外的环境下工作，但我遇到了相反的问题。

这是链接：

http://www.underagedriven.co.uk/ins/timeclick2.php

以及代码的快照，该代码在 IE 下不会出现任何错误，但不会与其他任何东西（Opera、iPhone Safari、Chrome、FF）一起使用，

我知道这会是一些愚蠢的事情，但我已经为此工作了一整天（我不是一个合适的编码员）当它不玩球时，我的眼睛有点呆滞。

任何帮助都可以为我指出正确的方向:)

谢谢，里克

Usually I hear about code working under things apart from IE but Ive got the opposite problem.

Here's the link :

http://www.underagedriving.co.uk/ins/timeclick2.php

And a snapshot of the code that doesnt kick any errors under IE but wont play ball with anything else (Opera, iPhone Safari, Chrome, FF)

I know its going to be something daft but having worked on this all day (Im not a proper coder) when it wasnt playing ball my eyes kinda glazed over .

Any help appreciated pointing me in the right direction :)

Thanks, Rik

name= 属性在标记上没有意义。如果您真正想要的是 id，请显式设置 id=。

您可能想熟悉 jQuery JS 库。它使很多类似的任务变得更加容易。

您的问题是您正在使用 name 属性的值，但将其与 getElementById 一起使用，后者适用于 id 属性。由于每个 name 属性值都是唯一的，因此您只需将它们更改为 id 属性，代码就应该可以工作。或者您可以将调用更改为 getElementById 到 getElementsByName。

由于 getElementsByName 返回一个集合，如果您采用该方法，您将需要选择返回集合的第一个成员，如下所示：

if (document.getElementsByName(itemname)[0].src ...)

但为了稳健，您需要：

var el = document.getElementsByName(itemname)[0];
if (el && el.src == ...) {
    ...
}

应采用类似的方法调用getElementById。

使用 getElementById 的代码可以在 IE（以及一些模仿其行为的浏览器）中运行，因为它总是混淆 name 和 id 属性，将它们本质上视为同一事物。它不适用于符合标准的浏览器，并且可能不适用于标准模式下的 IE 9。

Your problem is that you are using the value of the name attribute but using it with getElementById, which works on the id attribute. Since each name attribute value is unique, you can just change them to id attributes and the code should work. Or you can change the call to getElementById to getElementsByName.

Since getElementsByName returns a collection, if you adopt that approach you'll need to select the first member of the returned collection, something like:

if (document.getElementsByName(itemname)[0].src ...)

But to be robust, you would need:

var el = document.getElementsByName(itemname)[0];
if (el && el.src == ...) {
    ...
}

A similar approach should be adopted with the call to getElementById.

The code using getElementById works in IE (and some browsers that mimic its behaviour) because it has always confused name and id attributes, treating them essentially as the same thing. It doesn't work in standards compliant browsers, and probably won't work in IE 9 in standards mode.
