Change from a Button to an Image

Posted on 2013-01-12

I'm using this code that has buttons to load a listbox.  However, instead of buttons I want to use images to click on.  How would I switch this code so that I can click on an image as opposed to a button?

	$(document).ready(function() {
	$("button").click(function() {
	display( $(this).val() );
		})
	})

	function display(what)
	{
	$.getJSON("mydoggie.php?ajax=true", { "case" : what }, function(data) {
	$("#Doggie").empty();
	$.each(data, function(index, objRecord) {
	$("#Doggie").append('<option value="' + objRecord.ID + '">' + objRecord.Name + '</option>');
			});
		});
	}
</script>
</head>
<body>
<form>
    <button type="button" value="Place">Place</button>
 code]

This is what I am using for a clickable image now...
[code]   <input type="image" onClick= "javascript:display()"
              onMouseOver="MM_swapImage('Search','','SearchByPlace.jpg',1)"
              onMouseOut="MM_swapImgRestore()" src="Glass-Place.jpg" alt="Place"
              align="middle" width="160" height="151" value ="Place">[/

	{
		$(this).val()
		$.getJSON("mydoggie.php?ajax=true", { "case" : what }, function(data) {
			$("#Doggie").empty();
			$.each(data, function(index, objRecord) {
			$("#Doggie").append('<option value="' + objRecord.ID + '">' + objRecord.Name + '</option>');

instead : $("button")

Have this, and nothing is happening.

$("input:image").click(function() {
display( $(this).val() );
		})
	})
<input type="image" onClick= "javascript:display()"
onMouseOver="MM_swapImage('Search','','SearchByPlace.jpg',1)"
onMouseOut="MM_swapImgRestore()" src="Glass-Place.jpg" alt="Place"
align="middle" width="160" height="151" value ="Place">

replace :
$("input:image").click(function() {
         display( $(this).val() );
})

Open in new window

by :
$("input:image").click(function(evt) {
        evt.preventDefault();
        display( $(this).val() );
})

image button submit the page, this is so fast that you may not notice that. if the page refresh you lost all change made by the ajax call (if it reach before...)

evt.preventDefault() allow to break propagation of the submit event

if you have no intention of submitting the form, dont use an image at all.

<a href="#" class="button" title="Place"
onMouseOver="MM_swapImage('Search','','SearchByPlace.jpg',1)"
onMouseOut="MM_swapImgRestore()"><img src="Glass-Place.jpg" alt="Place"
align="middle" width="160" height="151" border="0"></a>

and do

$(".button").on("click",function(e) {
  e.preventDefauilt(); // here too
  display( this.title );
});

Why would this be?  I'm new to this, all I want to do is click on an image and populate the list box.  Is this submiting the form?  Should that matter if its an image or a button? Thank you.

input type=image IS a submit button
input type button is not
a link is not either.

My suggestion is the most logical to use since you do not need to think about the form at all.
