You should move the jQuery code into $(document).ready.您应该将 jQuery 代码移动到 $(document).ready 中。 I suspect you're preventing certain scripts from loading appropriately by running the code inline rather than in .ready.我怀疑您通过运行内联代码而不是 .ready 来阻止某些脚本正确加载。 I'm running the same version of jQuery (but not UI block) with ScriptManager in 3.5 right now, no prob.我现在正在 3.5 中使用 ScriptManager 运行相同版本的 jQuery（但不是 UI 块），没有问题。

AJAX is not a thing - its a bunch of technologies put together to achieve asynchronous communication. AJAX 不是一个东西——它是一堆技术放在一起来实现异步通信。 Yes, you have some JavaScript coding in there, but none of them actually do anything 'ajaxian' - a good example of something really AJAX-style would be an validation of a (registration) form or something like that.是的，您在那里有一些 JavaScript 编码，但它们实际上都没有做任何“ajaxian” - 真正 AJAX 风格的一个很好的例子是（注册）表单的验证或类似的东西。 You'd set some oberservers for some fields and validate them whilst the user is still making inputs on other fields...您将为某些字段设置一些观察者并在用户仍在其他字段上进行输入时对其进行验证...

I think what you're looking for is noConflict .我认为你正在寻找的是noConflict 。 It's been a while since I've used asp.net ajax but if I'm not mistaken, there is a $ function defined.自从我使用 asp.net ajax 已经有一段时间了，但如果我没记错的话，定义了一个$函数。
