Is it possible to test an input value in HTML before allowing a user to submit the data? In my HTML program, I have a form to fill out. However, I want to make sure that some of the valuss are filled in before submitting the form. So to ensure that, I want to test the value within the HTML (e.g. if statement) before showing the submit option to the user.

That is all JavaScript.

Bear in mind that if the reason you're counting on JavaScript to do your validation is because if the wrong information gets sent, it'll break your program, thats not a very secure approach.
One of the favorite pass-times of a ahem... friend of mine, is to take the source code to web page front ends, take out the Javascript validation parts, make the paths absolute, and launch the page locally to see what kind of weird stuff I... uhhh.. he.... can push into the webserver.
