HTML Form onSubmit()

Question

My HTML form is clearing automatically after I click the submit button. Any idea how to stop this from happening?

Here's the opening tag for the form:

<form onsubmit="return math()">

One popular approach is to utilize a server-side language such as PHP which reads all the get values and recreates the HTML of the page using a template and substituting in variables.

<input type = "text" name = "Textbox1" id = "Textbox1" value = "{$_GET[Textbox1]}"/>

I've written it out as $_GET directly, but you'd really want to make sure the value was scrubbed so you don't get arbitrary html injection.

A little bit more complicated you could approach this purely client side and utilize javascript to parse the address bar and extract the values submitted to your page (assuming it wasn't submitted with POST as the method). Then you can dynamically repopulate the fields client side.
