什么可能导致JQuery的选择器崩溃？-WhatcouldpossiblycauseJQuery'sselectortobreak?

Are you using any other libraries that might overload $ ? I know that e.g. that Prototype does this.

您是否正在使用任何其他可能超载$的库?我知道,例如Prototype做到了这一点。

You might want to try issuing a jQuery('#outputDiv') instead to see if it is actually jQuery that you are invoking.

您可能想尝试发出一个jQuery('#outputDiv'),看看它是否实际上是您正在调用的jQuery。

Check that jQuery is actually loaded. Have you tested with Firebug or another debugger? Are Javascript errors reported? Do you use another library that uses $ as an alias?

检查jQuery是否实际加载。您是否使用过Firebug或其他调试器进行过测试?是否报告了Javascript错误?您是否使用另一个使用$作为别名的库?

If you're using IE7 the order of when things happen are very important, and selectors don't tend to work for dynamically generated content if the jQuery script is declared beforehand, i.e. in the head element.

如果您正在使用IE7,那么事情发生的顺序非常重要,如果事先声明了jQuery脚本,那么选择器不适用于动态生成的内容,即在head元素中。

A way we got around this was to place the code at the end of the document. As weird as this sounds, it is documented by MS as a bug that's existed for many years.

我们解决这个问题的方法是将代码放在文档的末尾。听起来很奇怪,MS将其记录为存在多年的错误。
