Submit

Någonting sådant här kanske:

<script type="text/javascript">
<!--

var submitObj = null;
var disabledImg = "disabled.gif";
var enabledImg = "enabled.gif";
var mouseoverImg = "mOver.gif";

function checkState(o){
	var user = o.form.elements[ "user" ];
	var pass = o.form.elements[ "pass" ];

	submitObj.src = ( user.value.length > 0 || pass.value.length > 0 ) ? enabledImg : disabledImg;
};

window.onload = function(){
	for( var i=0; i < document.forms[ "foo" ].childNodes.length; i++ ){
		if( document.forms[ "foo" ].childNodes[ i ].type == "image" )
			submitObj = document.forms[ "foo" ].childNodes[ i ];
	}

	if( submitObj ){
		submitObj.onmouseover = function(){
			if( this.src.indexOf( disabledImg ) == -1 )
				this.src = mouseoverImg;
		}

		submitObj.onmouseout = function(){
			if( this.src.indexOf( mouseoverImg ) != -1 )
				this.src = enabledImg;
		}

		submitObj.onclick = function(){
			if( this.src.indexOf( disabledImg ) == -1 )
				this.form.submit();
			else
				return false;
		}
	}
};
