Disable submit button with saved time after page refresh
<p>I have account with two <code>input</code>s and one <code>submit</code> button.</p>

<p>After clicking the submit button, I want to disable it for 30 minutes, and if the user refresh  the page, the timer should not be reset and the button should be disabled, may be with cookie?</p>

<p>I found this: <a href="http://stackoverflow.com/questions/8108490/time-control-of-a-submit-button">Time control of a submit button</a></p>

<p>But how do I make it to show how much time left on the button name?</p>

<p>Thanks.</p>
