As we know, IE 9 and below doesn’t support the placeholder attribute. So placeholder watermark does not display in IE with twitter bootstrap.
Solution for this problem.
We can use ezpz-hint jquery js to resolve placeholder issue with IE or twitter bootstrap
Step 1:
Download ezpz-hint js
Step 2:
Include this js on page
<script type="text/javascript" src="jquery.ezpz_hint.js"></script>
Step 3:
If you want to apply on all text box then use like this:
$("input[type=text]").ezpz_hint();
