Onclick at an icon inside a form

Hello,

I want to add an icon inside a form and be able to click it and run javascript code once clicked.Basically,i know how to add the icon on the form but i don’t know how to make it clickable with OnClick.

the input code for the text field is

[code=html]<input id=”cool” style=” width:45&#37;;

padding:4px; padding-right:25px;” type=”text” name=”game” > [/code]

and the css code for the icon

[code=html]
#cool {
background: url(game.jpg) no-repeat scroll 448px -1px;;

cursor:hand;
cursor:pointer;
}
[/code]

But i don’t know as i said where i should place OnClick command in order to make [B]only[/B] the icon clickable.Thanks.
