asp.net mvc4 jquery无法正常工作

I'm trying to run a jquery code which was put in my _Layout.cshtml as below:

我正在尝试运行一个jquery代码，它放在我的_Layout.cshtml中，如下所示：

...............
<script type='text/javascript'>
$(document).ready(function () {
   alert('Test');

});
</script>
  @Scripts.Render("~/bundles/jquery")
  @RenderSection("Scripts", required: false) 
</body>
</html>

The above code wasn't fired and when I inspected with Chrome Dev, it showed $ is not defined ( I can see all my jquery, jquery ui files are loaded )

上面的代码没有被解雇，当我用Chrome Dev检查时，它显示$未定义（我可以看到我的所有jquery，jquery ui文件都已加载）

It worked if I put this code in an external js file

如果我将此代码放在外部js文件中，它就可以工作

I don't mind putting all my jquery code in external files, but really wanna clarify where I am doing wrong.

我不介意将我的所有jquery代码放在外部文件中，但我真的想澄清我做错了什么。

You need to introduce jquery before your script.

您需要在脚本之前引入jquery。

@Scripts.Render("~/bundles/jquery")

<script type='text/javascript'>
$(document).ready(function () {
   alert('Test');

});
</script>

  @RenderSection("Scripts", required: false) 
</body>
</html>

Andreas, i have the same issue.. for default the "_layout.cshtml" has "@Scripts.Render("~/bundles/jquery")" at the end of the document, but it doesn't work.. i cut it and paste it in the head and now it is working.

安德烈亚斯，我有同样的问题..默认情况下，“_layout.cshtml”在文档的末尾有“@ Scripts.Render（”〜/ bundles / jquery“）”，但它不起作用..我切它并将其粘贴在头部，现在它正在工作。

In order for jQuery to work, your script should come after <script src="/Scripts/jquery-2.0.3.js"></script>

为了使jQuery工作，你的脚本应该在

In the _Layout.cshtml, just before the </body> tag you can find something like this

在_Layout.cshtml中，就在标记之前，您可以找到类似这样的内容

@Scripts.Render("~/bundles/jquery")
@RenderSection("scripts", required: false)

First you have the jQuery library. Then you have any scripts. That's what this means. So in your views do something like this.

首先你有jQuery库。然后你有任何脚本。这就是这意味着什么。所以在你的观点中做这样的事情。

@section scripts{
 //your script
}

This will make sure that all scripts comes under jQuery reference.

这将确保所有脚本都在jQuery引用下。
