How to catch users input with html() ?

Hello !

When you try to select some HTML modified by the user like an input, it returns the original html.

Example : <input type="text" value="" name="test" />

If the user write "something" in the textbox and then echo the html, the input value will still be null. (At least in firefox)

Is there a way to catch these inputs as well ?
