This extension replaces standard HTML checkboxes and radio buttons with an image-based alternative. The images are inserted as background:url() CSS directives for <span /> elements. The standard HTML elements behind the scenes are still used for the form inputs, so nothing special needs to be done in order to capture the information when the form is submitted.

Options:

  • rating - Set this to 1 or true if the radio button list / checkbox list is to be used as a "rating" system (i.e., checking the 4th radio button will cause the previous 3 to be lit up, as well).

Usage:

The extension acts upon jQuery selector objects. You may either pass through the rating parameter to use a "rating" system, or pass nothing in order to use standard radio button list / check box behavior.

The "radio_img" class is added to the elements acted upon by the .imgradio() call. The "checked" class is also added to checked Image Radio elements. It is up to you to define the styles that take advantage of these two classes.

Make sure that the elements being replaced have id attributes. If they don't have an ID, then it won't work!

Examples:

<style type="text/css">
span.radio_img {
  background:url(star.jpg);
  height: 12px;
  width: 12px;
  margin-right: 2px;
  display: inline-block;
}
span.radio_img.checked {
  background:url(star-bright.jpg);
}
</style>
<script type="text/javascript">
$('.my_radio_buttons').imgradio(); // standard behavior
$('.my_rating_stars').imgradio(1); // "rating" system
</script>
