Replace Form Reset Button With an Image

You may already know how to replace the default gray form submit button with an image (see Tip "Replace Form Buttons With Images"), but do you know how to replace the default gray form reset button with an image? You can do this using JavaScript. The idea is to create a function that will loop through each form element on the page and blank it out or return it to its default state. To create a reset image button, just link the image to the script, which should be placed in the head of the page.
 
<script>
function reset() {
	// The number of elements in the form
	var x = document.myForm.elements.length;   
	// Loop through all elements in the form and blank them out
	for (i=0; i<x; i++) {  
		if (document.myForm.elements[i].type == "text" || 
			document.myForm.elements[i].type == "textarea") {
			document.myForm.elements[i].value = "";
		}
		else if (document.myForm.elements[i].type == "select-one") {
			document.myForm.elements[i].selectedIndex = 0;	
		}	
		else if (document.myForm.elements[i].type == "radio" ||
		 		 document.myForm.elements[i].type == "checkbox") {
			document.myForm.elements[i].checked = false;	
		}	
	}
}
</script>
