Implement placeholders in either html or razor view using jquery very easily

Jquery has very simple plugin for showing placeholders in textfields and textareas when they are empty like this :

you can download its plugin form there : http://matoilic.github.io/jquery.placeholder/

To use it in your applications just use its library in header like this :

<script src="jquery.placeholder.js"></script>
and use these lines:
<script>
    $('input[placeholder], textarea[placeholder]').placeholder();
</script>

in header and you can use in html like this :
<input type="password" placeholder="password" name="password">

and if you want to use this in asp.net mvc razor views , then use it in this way :
 @Html.TextBoxFor(x => x.Email, new { placeholder = "Email" })

That is how placeholders can be implemented very easily in any technology using jquery.
