Input mask is not firing in asp.net

i have input mask set for each textbox that is not firing.

but script javascript is firing fine.

code is copy pasted from anot开发者_如何转开发her page of same website and page which get copied is working fine

I dont know what js library are you using orwhat is your problem without any code, but I am showing what I use and how I use to do the input mask

I use jquery and a plugin called masked Input plugin

All you need to is to include the two js libraries into your page

<script src="jquery.js" type="text/javascript"></script>
<script src="jquery.maskedinput.js" type="text/javascript"></script>

than just call them

<script>
    jQuery(function($){
       $("#date").mask("99/99/9999");
       $("#phone").mask("(999) 999-9999");          
    });
    </script>

supposing you have this textboxes

<input id="date" type="text" />
<input id="phone" type="text" />

It will automatically do input mask for you
