Create a new html file and name it test.html to explain how jquery stops function execution. Use div tags to create a module for digital output display. Create an id attribute for the div tag, which is used to obtain the div object below.

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

Open the test.html file in the browser, click the button to view the results.
