为什么IE8不识别type =" application / javascript"在脚本标签？ [英] Why doesn't IE8 recognize type="application/javascript" in a script tag?
问题描述
我开发了一个使用jQuery和Ajax的HTML页面。我的< head> 标记中包含以下行：
I developed an HTML page that uses jQuery and Ajax. I had the following lines in my <head> tag:
<script language="javascript" type="application/javascript" src="script/jquery.js"></script>
<script language="javascript" type="application/javascript">
function someFunction() {
some code;
}
</script>
...
later - down in the body tag:
<a href="javascript:someFunction();">click here</a>
它在FF和Chrome中运行得非常好，但是我在IE8中尽快投放了预期的对象点击链接。即使启用了脚本调试器，它也无法到达函数的第一行。
我尝试切换到IE7模式，或IE8 Compatability模式 - 无济于事。
我很幸运，发现了通过Google提问，有人建议将< script> 标记中的类型更改为 text / javascript现在它适用于所有3种浏览器。
我的问题是：我做错了什么？是text / javascript优于application / javascript，还是有更好的（==更正确解决我的问题？
It worked perfectly in FF and Chrome, but threw an "Object Expected" in IE8 as soon as I clicked the link. Even with the Script Debugger on, it would not reach the first line of the function.
I tried switching to IE7 mode, or IE8 Compatability mode - to no avail.
I lucked out and found a question through Google where someone suggested changing the type in the <script> tag to "text/javascript" and now it works in all 3 browsers.
My question is: what did I do wrong? Is "text/javascript" better than "application/javascript", or is there a better (== more correct) solution to my issue?
推荐答案
text / javascript是所有三种浏览器都支持的唯一类型。但是，您实际上并不需要输入类型。如果没有另外指定，脚本标记的type属性将默认为text / javascript。这将如何影响验证，我不确定。但无论如何这真的很重要吗？
"text/javascript" is the only type that is supported by all three browsers. However, you don't actually need to put a type. The type attribute of a script tag will default to "text/javascript" if it is not otherwise specified. How that will affect validation, I'm not sure. But does that really matter anyway?
