Disable Image Submit Button Script

[JohnSaunders]

I'm trying to use the script below to disable an image submit button. For some reason it isn't working. Does anybody see what's wrong with it?

// this goes in the anchor tag for the submit imageonclick="var obj=disable(this);"
 
// this goes in the form tag
onsubmit="return disablebutton(obj);" 
 
// this goes in the head tag
function disablebutton(obj){
 obj.disabled=true;
}

You can use this

<input name="img" type="image" src="images/image.jpg" id="button" onsubmit="this.disabled = 'true';">

or

<input name="submit" type="submit" id="button" onsubmit="this.disabled = 'true';">

so the disabled effect only appears in te second case

Bye
