A reference to the jquery library

1. After several trial pits, the easiest way to find out is to download the jquery file directly on the official web page .

2. There are two download versions on the official website, one is compressed (for publishing) and one is uncompressed (easy to read and learn).

3. Then I will download the uncompressed version if I use it.

4. Click on the compressed version of the file will pop up a js file press ctrl+s to save the file locally.

5. Call Jquery:<script src= "Js/jquery-3.3.1.js" in the project ></script>

Write the above code in the head tag of the HTML file ( Note: before the introduction of the other JS files, because the browser is called sequentially, to load the library before it can be used)

6. Call the jquery library and you're done!
