ASP.NET中外部javascript文件中的jQuery

Question

How to use jQuery in external javascript file in ASP.NET? 如何在ASP.NET的外部javascript文件中使用jQuery？

This is my code : 这是我的代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="~/Javascript/Javascript.js" runat="server"></script>
    <script src="~/Javascript/jquery-2.1.1.js"></script>
</head>

But in Javascript.js file, I can't use jQuery selector $() . 但是在Javascript.js文件中，我不能使用jQuery选择器$() 。 When I use it doesn't work. 当我使用它不起作用。

Javascript.js : Javascript.js ：

$(document).ready(function () { 
  alert('Hello'); 
});

This code doesn't work. 此代码无效。 Also IntelliSense doesn't work in Javascript.js. 同样，IntelliSense在Javascript.js中也不起作用。

You have to include jQuery before Javascript.js 您必须在Javascript.js之前包含jQuery

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="~/Javascript/jquery-2.1.1.js"></script>
    <script src="~/Javascript/Javascript.js" runat="server"></script>
</head>

You said you have these errors in your developer console: 您说过在开发人员控制台中有以下错误：

Failed to load resource: the server responded with a status of 404 (Not Found) localhost:46316/~/Javascript/Javascript.js 
Failed to load resource: the server responded with a status of 404 (Not Found) localhost:46316/~/Javascript/jquery-2.1.1.js 
Uncaught TypeError: undefined is not a function

You can fix these by setting the paths to your files correctly: 您可以通过正确设置文件路径来解决这些问题：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="/Javascript/jquery-2.1.1.js"></script>
    <script src="/Javascript/Javascript.js" runat="server"></script>
</head>

Make IntelliSense work by putting this line of code to Javascript.js (as you realized yourself): 通过将以下代码行放入Javascript.js（使自己意识到自己），使IntelliSense起作用：

/// <reference path="jquery-2.1.1.js" />

Read the documentation of IntelliSense features and reference directives in here: http://msdn.microsoft.com/en-us/library/bb385682.aspx#Features 在此处阅读IntelliSense功能和参考指令的文档： http : //msdn.microsoft.com/zh-cn/library/bb385682.aspx#Features
