对jquery库+外部文件的html引用

Question

I am wondering how to reference jquery in html .

To my understanding there has to be 2 links:

1. To the library
2. To the external file.

here is my reference that does not seem to work..

<script type="text/javascript" src="jquery.js" ></script>
<script src="jquery-2.1.3.js"></script>

ps. 1st time here, I know the question sounds stupid, I'm just going crazy with that

Answer 1

You only need one reference. Let's say your folder structure is like this:

my_project/
    index.html
    jquery.js

Then in your index.html you just need to do this:

<script type="text/javascript" src="jquery.js" ></script>

To include the JS file. If however you don't have jquery.js there, and you want to reference it from a CDN (content delivery network). You could do something like this:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js" ></script>

Answer 2

It's good practice to use a CDN, or content delivery network, as the host for jQuery and other similar libraries. This article does a good job of explaining the benefits. One example of a quality, free CDN is Google . Here's how you would include Google's version of jQuery 2.1.3:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

Answer 3

link from file

<script type="text/javascript" src="js/jquery.js"></script>

link from source

<script type="text/javascript" src="http://thesource.com/jquery.js"></script>

internal script

<script> // javascript here </script>

Answer 4

1 to the library: <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

2 to the external js file: <script type="text/javascript" src="/js/pinkmoon.js"></script> , assuming that js file is in the same folder as index.html
