I need to remove CSS hover functionality using JavaScript.

I have a button on a form which submits data to our db server. Using `OnClientClick()` of an ASP.NET Button control I would like to change the element's text to 'Submitting..' using `getElementById()`, change the background color of the button to Light Grey and **more importantly disable the following .button:hover effect** I have in my CSS.

```
.button:hover, 
.content-form input.button:hover, 
#comment-form #submit:hover   
{
    background-color: #333;
}

```

All I am really interested in is the Javascript to remove/disable the above CSS 

```
e.g. OnClientClick="getElementByID('ButtonName').blahblahblah;"

```
