What is the process for obtaining a compilation of JavaScript files that are run when an event is triggered?

How can I generate a list of all the JavaScript files that are triggered when a button is clicked or an input field is selected in a complex system?

Is it possible to achieve this with Chrome DevTools, or are there alternative solutions available? If Chrome DevTools can be used for this purpose, then how exactly can I do it?

The Challenge: I am struggling to locate the file containing the function that I need to intercept in order to add my custom validation before a button click redirects to another page. Knowing the names of the files would greatly benefit me as the system adheres to clean code principles.

UPDATE: I came across this helpful tutorial, but unfortunately, none of the suggested solutions seem to be effective (breakpoints are not functioning properly). Following the advice of @Carles Alcove in the mentioned post, I installed the Visual Event extension which led me to the knockout.js file. In that file, I inserted the console.trace() function as recommended by @guest271314. The first image shows my inspection of the button using dev-tools as advised by @user3297291, while the second image displays the result after integrating the function.

Answer №1

To enhance debugging, consider integrating console.trace(), console.profile(), and console.profileEnd() into the click event handler. This will allow you to analyze file line numbers using the console and Profiles tabs within DevTools.

Answer №2

If you want to get an idea of the event listeners connected to a specific element, you can use the developer tools by following these steps:

  • Right-click on the element
  • Select Inspect element from the context menu
  • Navigate to the Event Listeners tab in the right panel of the developer tools
  • Look for any mouseup or click events.

You will be able to see the functions attached and their corresponding file names. Although this method may not work for all types of event listeners (for example, those bound to parent elements), it is a convenient way to anticipate which functions might be triggered.
