Question

I am trying to change the class of a button when a checkbox is checked but I’m having trouble getting it right. When the checkbox is selected I want to change the buttons class to buttonsshow from buttonshide.

HTML

<div class="checkbox">
    <input id="ChartstoDisplayAll" type="checkbox"     name="ctl00$MainContent$ChartstoDisplayAll" /><label for="ChartstoDisplayAll">Select All</label>
    <p class="checkbox" style="margin-left:5px;"> or select individually below </p>
    <hr class="horizline" style="width:870px;"/>
</div>

    <div id="buttons" class="buttonshide">
        <input type="image" name="ctl00$MainContent$btnGetChart"  id="MainContent_btnGetChart" title="Click here to retrieve the charts" Text="Build the  Charts" src="Styles/Images/stats.png" alt="Build the Charts" align="left" />
        <p style="font-size:.8em; font-weight:bold;">Build Charts</p>
    </div>

FYI…There is other html between these two divs. I took it out for brevity as none have an id of buttons.

Here is the javascript. (the latest way that I’ve tried)

 //this script will change the style of the "Select All" checkbox and make visible the "Build Chart" button
  $(document).ready(function () {
      $('#ChartstoDisplayAll').click(
          function () {
              $("INPUT[type='checkbox']").attr('checked', $('#ChartstoDisplayAll').is(':checked'));
              $(this).next().toggleClass("selected");
              $(this).find("buttons").toggleclass("buttonsshow");
          });
  });

Here is the fiddle link

Here is the completed, working script which changes the text color and shows the button when the checkbox is selected.

 //this script will change the style of the "Select All" checkbox and make visible the "Build Chart" button
  $(document).ready(function () {
      $('#ChartstoDisplayAll').change(
          function () {
              if ($('#ChartstoDisplayAll').is(':checked')) {
                  $(this).next().addClass("selected");
                  $('#buttons').addClass("buttonsshow").removeClass('buttonshide');
              } else {
                  $('#buttons').addClass("buttonshide").removeClass('buttonsshow');
                  $(this).next().removeClass("selected");
              }
          });
  });

Answer 1

Try this:

if ($('#ChartstoDisplayAll').is(':checked')) {
  $(this).find("buttons").addClass("buttonsshow").removeClass('buttonshide');
} else {
  $(this).find("buttons").addClass("buttonshide").removeClass('buttonsshow');
}

Also, you should use the change event instead of click
