How can I show/hide a div based on checkbox click on my website? It works in jsFiddle, but not on my actual site. Any suggestions?

Is there a way to show or hide a div based on a checkbox click? I've got it working in jsFiddle, but for some reason, it's not functioning properly on my website. Any thoughts on how to fix this?

My goal is to offer multiple payment methods (credit card, Paypal, etc.) and display the relevant payment information based on the method selected. Here's the link to the jsFiddle example:

http://jsfiddle.net/mxRCz/88/

This is the JavaScript code I'm using:

$('#CCMethod').change(function(){
  if (this.checked) {
    $('#CCPay').fadeIn('slow');
  } else {
    $('#CCPay').fadeOut('slow');
  }                   
});

Answer №1

Your script may not be functioning properly due to the order in which it is running.

  $('#CCMethod').change(function(){
      if ($(this).is(':checked')) {
        $('#CCPay').fadeIn('slow');
      } else {
        $('#CCPay').fadeOut('slow');
      }                   
    });

To ensure that #CCMethod is declared before your script runs, wrap it in a document ready function:

$(function() {
    ('#CCMethod').change(function(){
      if ($(this).is(':checked')) {
        $('#CCPay').fadeIn('slow');
      } else {
        $('#CCPay').fadeOut('slow');
      }                   
    });
 });

Answer №2

To improve functionality, consider using the click event instead of change. The change event may have some bugs in older versions of Internet Explorer (jQuery might fix this issue, but it's good practice to use click). Give it a try and see if click works better for you.

If you're not concerned about compatibility with IE<9, check out the :checked pseudoselector. This option doesn't require javascript. Here's an example: http://jsfiddle.net/y9cQD/ (you can add show/hide animation using transition)

P.S. I also just noticed J Torres' answer - that could be the reason for the issue.

Answer №3

Modify the following line:

if (this.checked) {

to this:

if ($(this).is(':checked')) {

To verify the status of a checkbox, utilize the ':checked' jQuery selector.
