What is the best way for OnSubmit to access an external file?

Recently, I adjusted this code snippet to include the onsubmit attribute with a validation function call. Instead of having the validate function within the same file, I moved it to an external file for better organization. Now, I am wondering how do I ensure that the HTML file calls the external validation file correctly?

Answer №1

Make sure to include the following code in your HTML file:

<script type="text/javascript" src="[file path]"></script>"
.

It's important to ensure that the script file is loaded before utilizing the function. If you're loading synchronously, place the script tag above the block of code where you call the validate function.
