Understanding the Difference Between Using Inline and External Javascript

At times, it's crucial for JavaScript to execute promptly. For example, consider a scenario where I have radio buttons in a form, and when the form fails to submit, JavaScript automatically selects the last button chosen by the user. If one button is preselected and then changes due to JavaScript, it could appear visually odd to the user. Therefore, running the script as soon as possible seems necessary, with inline JavaScript potentially aiding in this goal. Will employing inline JavaScript significantly reduce instances of users encountering such peculiar behaviors?

javascript

Answer №1

Unfortunately, it's impossible to ensure that your JavaScript will execute quickly enough to prevent the user from seeing the update regardless of its placement.

The best approach is to adjust the HTML within the form generated by the server to display the user's previous selection as the default selected radio button.
