Checkbox Stays Checked When Clicking On It In A Dropdown

Question

I have a dropdown list containing checkeboxes :

Solution 1:

The problem is because you cannot wrap a form input in an <a> element. The a will intercept the click event.

To fix this you can instead wrap the inputs in a label. You can also massively simplify your code by using the value of the checkbox to hold the column name, and also toggle() with the checked state of the checkbox. You can then also hook to the change event on the checkboxes directly as the <a> will not be interfering with the click event. Try this:

$('#columnsListDropDown :checkbox').on('change', function() {
  $("#myTable").find("[data-column='" + this.value + "']").toggle(this.checked);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<ul class="dropdown-menu columnsFilterDropDownMenu" id="columnsListDropDown">
  <li>
    <label class="small" data-value="Type">
      <input type="checkbox" checked="" value="Type">
      Type
    </label>
  </li>
  <li>
    <label class="small" data-value="Release">
      <input type="checkbox" checked="" value="Release">
      Release
    </label>
  </li>
</ul>

<table id="myTable">
  <tr>
    <td data-column="Type">Type</td>
    <td data-column="Release">Release</td>
  </tr>
</table>

Solution 2:

Use event.stopPropagation() and event.preventDefault to disable events

    var input = $(this).find("input");
    var columnName = $.trim($(this).text());
    if (event.target.localName === "input") {
    // Case where user has clicked on the input
        if ($(input).is(':checked')) {
            $("#myTable").find("[data-column='"+columnName+"']").show()
        } else {
            $("#myTable").find("[data-column='"+columnName+"']").hide()
        }
    } else {
     event.preventDefault();
     event.stopPropagation();
    // Case where the user has clicked on the label, or in li element
        if ($(input).is(':checked')) {
            $("#myTable").find("[data-column='"+columnName+"']").hide()
            $(input).prop('checked', false);
        } else {
            $("#myTable").find("[data-column='"+columnName+"']").show()
            $(input).prop('checked', true);
        }
    }
    return false;
});
