I would like to know if JQuery BlockUI plugin can be used to disable a input field directly. 

I see the samples on jquery plugin.

<http://jquery.malsup.com/block/#element>.

when I give just the input field id in the jquery selector, it is not working.

```
$(document).ready(function() { 

    $('#blockButton').click(function() { 
        $('#inputId').block({ message: null }); 
    })

```

when I just give the input field id, it doesn't work, but instead if i give anchor tag id or a div tag id it is working fine.

is there a solution to block just the input fields(text, select etc).

please do let me know.
