jQuery function on form input
<p>I want users to enter something in an text field, press OK and then run a function on the value of that text.</p>

<p>I have been looking at jQuery docs, I found keyup which gets the value instantly (not what I want) and the only things I can find about doing stuff with submitted form data involve POSTing the results to a php file or something.</p>

<p>I am keen to learn so if you could post links to resources where I could find out more along with your answer I would be most grateful. Thanks.</p>
