Javascript validating imput from prompts

On this page I discuss the limitations of using Java Script to check a form, then I'll explain the onsubmit event handler, followed by the few methods and properties of the form itself.

Then it's time for accessing the form elements and the specific syntax for accessing the user defined value of form elements.

After all, the input box and you have to change the script.

I created an example form and script that you can study to get the hang of it.====================================== Sat, - Debian 8.6 released ======================================

Of course we don't have any info about this kb object but just in case it's a I think that's correct, if you don't want to deal with the exceptions. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
