Missing CSS class after a jQuery replaceWith? Need help resolving this issue?

I made a recent addition to the master.cs page.

<h4 class="hideAndShow">[ - ] Hide</h4>

Here's the corresponding code in my CSS file:

.hideAndShow
{
    position: fixed;
    top:120px;
    right:420px;
    color: white;
    background-color:green;
}

Following that, I included this script within the same master.cs page.

        <script>
            var hideShowBool = true;

            $('.hideAndShow').bind('click', function ()
            {
                if (hideShowBool == true)
                {
                    $(this).replaceWith('<h4 class="hideAndShow">[ + ] Show</h4>');
                    hideShowBool = false;
                } else
                {
                    $(this).replaceWith('<h4 class="hideAndShow">[ - ] Hide</h4>');
                    hideShowBool = true;
                }
            });
        </script>

The intended behavior: The text [ - ] Hide should switch back and forth between: [ + ] Show and [ - ] Hide.

However, the current issue is that it only changes with the initial click. After replacing [ - ] Hide with [ + ] Show, subsequent clicks do not trigger any changes as expected.

What could be causing this problem? And how can it be rectified?

Answer №1

One reason this is happening is because when you replace an element, the new element doesn't inherit any click handlers that were previously bound to it. One possible solution is to use event delegation:

$('#aStaticParentElement').on('click', '.hideAndShow', function () {

Another option is to modify the text content of the element instead of replacing it entirely:

$('.hideAndShow').on('click', function() {
    $(this).text(function(_, currentText) {
        return currentText === '[ + ] Show'
               ? '[ - ] Hide'
               : '[ + ] Show';
    });
});
