I have radio button inside li element, I would like to change the background color of the li (the parent div) once the radio button checked. I succeeded to set hover on the li by

Solution 1:

This should do it:

function updateHighlightRadio() {
  var selected = this.parentNode.parentNode.parentNode.getElementsByClassName("selected")[0];
  if (selected) selected.className = selected.className.replace(" selected", "");
  this.parentNode.parentNode.className += " selected";
}

function updateHighlightCheckbox() {
  var selected = this.parentNode.parentNode;
  if (!this.checked)
    selected.className = selected.className.replace(" selected", "");
  else
    this.parentNode.parentNode.className += " selected";
}

window.onload = function () {
  var radios = document.querySelectorAll("input[type=radio]");
  for (var i = 0; i < radios.length; ++i) {
    radios[i].onchange = updateHighlightRadio;
  }

  var checkboxes = document.querySelectorAll("input[type=checkbox]");
  for (var i = 0; i < checkboxes.length; ++i) {
    checkboxes[i].onchange = updateHighlightCheckbox;
  }
}

.job-manager-term-checklist {
  margin: 1em 0 0;
  padding: 0;
  list-style: none;
  overflow: hidden;
}
.job-manager-term-checklist li {
  border: 1px solid #ccc;
  overflow: auto;
  padding: 5px;
  margin-left: 5px;
  border-radius: 5px;
  background-color: #ebf1f9;
  width: 20%;
}
.job-manager-term-checklist li:hover {

  color: #fff;
}
.job-manager-term-checklist .selected {
  background-color: #a2156b;

}

Solution 2:

You can create a javascript file and change the class of the element like eg:

document.getElementById('id').classList.add('class');
document.getElementById('id').classList.remove('class');

You will have to change your <li> to eg:

<li id="job_listing_category-98"><label class="selectit"><input value="98" type="radio" name="tax_input[job_listing_category][]" id="in-job_listing_category-98" onclick="changeClass(this, "someClass")">7</label></li>

Hope this will point you in the right direction

Solution 3:

If I'm understanding your problem correctly, you could do it like this:

 form input[type="radio"]:checked + label {
   background-color: yellow;
 }

Solution 4:

You can make like this

$('input[type=radio]').on('change', function() {
    $('li').each(function(){
      $(this).removeClass('active');
    });
    if($(this).prop('checked')) {
      $(this).parent().parent().addClass('active');
    }
});

.job-manager-term-checklist { 
    margin: 1em 0 0;
    padding: 0;
    list-style: none;
    overflow: hidden;
  }

.job-manager-term-checklist li {
    border: 1px solid #ccc;
    overflow: auto;
    padding: 5px;
    margin-left: 5px;
    border-radius: 5px;
    background-color: #ebf1f9;
    width: 20%;
  }

.job-manager-term-checklist li:hover { 
  background-color: #4e83ca;
  color: #fff;
  }
.active {
  background-color: red !important;
}

    </ul>
    </div>

Solution 5:

Just use this small code :

$('input[name*="tax_input"]').change(function() {
    if($(this).is(':checked')) { // Input is checked
        $(this).parent().css('background', 'red');
    } else {
        $(this).parent().css('background', 'white');
    }
});
