Enhance your design with dynamic hover effects

I need assistance with modifying the menu structure generated by Wordpress. Specifically, I want to change the background of #header-nav li ul.children li a when

#header-nav li ul.children li ul.children li a:hover

is active.

Could someone provide guidance on the syntax required for this task?

<div id="header-nav">
    <li class="page_item page-item-10"><a>Marketing</a>
        <ul class='children'>
            <li class="page_item page-item-153"><a href="{link}">The Marketing Team</a></li>
            <li class="page_item page-item-148"><a href="{link}">Ideas</a></li>
            <li class="page_item page-item-136"><a href="{link}">Referrals</a></li>
            <li class="page_item page-item-156"><a href="{link}">Partnerships</a></li>
        </ul>
    </li>
</div>

My current approach involves identifying the parent class of the hovered element (e.g. 'page_item page-item-10' when the user hovers over 'Ideas') and using the .hover() function to change the background accordingly. However, I am unsure of how to retrieve the parent class. Any suggestions?

/**
 * Highlighs parent elements in a menu when a child is being hovered over
 */
$(function(){

    $('#header-nav li ul.children li ul.children li a').hover(function(e){

        /** Get the parent of the element that is being hovered over */
        var parent = ???;

        /** Set the background of the parent element on 'mouseenter' */
        $('#header-nav li ul.children li.'+parent+' a').css('background-color', '#0066B5');

    }, function(){

        /** Reset the background of all matching elelments of 'mouseleave' */
        $('#header-nav li ul.children li a').css('background-color', '#000');

    })
});

To trigger a JavaScript function when the mouse hovers over an anchor tag, you can use the "onmouseover" event.

For example:

<div id="header-nav">
<li class="page_item page-item-10"><a>Marketing</a>
    <ul class='children'>
        <li class="page_item page-item-153"><a id="menu1" onmouseover="change(this)" href="{link}">The Marketing Team</a></li>
        .
        .
        .
    </ul>
</li>

JavaScript

<script language="javascript" type="text/javascript">
    function change(obj) 
    {
      document.getElementById(obj).style.backgroundColor = '#fff';
    }

</script>

If you're feeling stuck in WordPress and can't make significant changes, you can take matters into your own hands by manually accessing and altering the child elements individually.

var ul = document.getElementById("header-nav").childNodes[1].childNodes[3];
// We're currently at the ul list...
var nodeCount = 1;
for(var i = 1; i <= ul.children.length; i++) {
  ul.childNodes[nodeCount].addEventListener("mouseover", doChanges, false);
  // You could also use ul.childNodes[nodeCount].onclick = handler...
  nodeCount += 2;
}

This process should be triggered when the document is ready. If you're using jQuery, you can insert this within the $(function() {}); or $(document).ready(function() {});

Now, let's talk about the handler, which we referred to as "doChanges" earlier. It essentially performs "something" on the elements within the loop. Here's an example of what it could look like:

function doChanges(e) {
  this.style.backgroundColor = "red"; // or any other color
  this.style.border = "solid 1px red";
}

So, this code snippet is specifically for the "mouseover" event. This event occurs when you hover your mouse over the respective li element (since we've attached an event handler to each one). The event handler, or the function that executes the desired action, modifies each of these li elements in some way.

You can also implement a "mouseout" listener if needed.

I hope this explanation clarifies things for you.
