If you don't want to download and store JQuery, you can also reference it through a CDN (content distribution network).
The servers of Baidu, Google and Microsoft all have jQuery.
JQuery Baidu CDN (domestic certainly choose Baidu or Sina)
Load Address:
Not compressed:
<script src= "Http://libs.baidu.com/jquery/2.0.0/jquery.js" ></script>

To quote jQuery from Google or Microsoft, use one of the following codes:
Google CDN:
Copy Code code as follows:
<script src= "Http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" >
</script>
Copy Code code as follows:
Http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js
Give it a shot yourself.
Tips: Get the latest available version via Google CDN:
If you observe what the Google URL is-a jQuery version (1.8.0) is specified in the URL. If you want to use the latest version of JQuery, you can also remove a number from the end of the version string (such as this example 1.8), and Google will return the latest available version of the 1.8 series (1.8.0, 1.8.1, and so on), or you can have only the first number, then Google will return 1 The latest available version (from 1.1.0 to 1.10.2) in the series.
Microsoft CDN:
Copy Code code as follows:
<script src= "Http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.0.js" >
</script>
Give it a shot yourself.
Tips: Using Google or Microsoft's jQuery has a big advantage:
Many users have already loaded jQuery from Google or Microsoft when they visit other sites. All the results are that when they visit your site, JQuery is loaded from the cache, which can reduce the load time. At the same time, most CDN ensures that when a user requests a file, it returns a response from a server closest to the user, which can also increase the load speed.
