Javascript inputtype=image disable

Question

Im trying to disable a submit button with an image on it like
forn name = Increase
input type = "image" name="image" src="image.gif"
//this is the javascript code
out.println("function newResourceDisab(){");
out.println("alert(\"Resource addition button disabled hopefully\");");
out.println("frm=document.forms['Increase']");
out.println("frm.image.disabled=true");
out.println("}");
typical input disabling doesnt seem to work for images.
anybody got any ideas.

There's no relation between JavaScript and Java, despite the similarity in names.
That said, the easiest way to do something like this is to add an onClick( ) argument to the input tags, or alternatively, the image tags. The onClick will call your Resource Disabling function.
I'm not sure if you simply want to toggle a value within the form, or if you actually want to submit the form while at the same time overriding the default behavior of expanding the image.
