Let's take a look at how to add attributes to the tag using the attr () method:

Create a new html file, named test.html, to explain how jquery adds attributes to tags.

Within the test.html file, import the jquery.min.js library file and load the file successfully before you can use the methods in jquery.

Within the test.html file, create a line of text for the test using the p tag.

In the test.html file, create a button using the button tag, bind the button button to an onclick click event, and execute the addsx () function when the button is clicked.

In the js tag, create the addsx () function, within which the p tag object is obtained by the element name, and the id of the p tag is set to mypp using the attr () method.

Open the test.html file in the browser, click the button, view the source code, and view the results.
