I've implemented this textbox watermark functionality on some of the text boxes in my solution:

It's very useful, but it's causing me some problems. Specifically, when I click the submit button when the watermark is present on a text box, the watermark text gets sent to the server. This means I have to do a test on the server to see if that text got sent, which isn't ideal.
could somebody suggest a client-side solution to this? So that when I click a button or a link which would normally end up bringing the text from the page to the server, that this is filtered out and nothing happens?
