Enhance the appearance of a tree node by applying style to the "li" element

Question

Enhance the appearance of a tree node by applying style to the "li" element

Here is a tree structure that I am working with - http://jsfiddle.net/anirbankundu/wzEBW/

This tree may contain any number of nodes. The requirement is that when a user hovers over a single node, the background color of the node should change. This can be achieved by adding a hover class to the li element. Only one node should be highlighted at a time. The styling involves adding the subsequent children of the li element (Refer to the fiddle link provided).

Can anyone provide assistance with this?

Answer №2

I decided to encase the "div" elements with "a" tags:

<script id="itemTmpl" type="text/html">
    <li>
        <a>
            <div>
                <a href="#" data-bind="click: $root.toggleChildren, text: showChildren() ? ' - ' : ' + '"></a>
                <a href="#" data-bind="text: name"></a> 
            </div>
            <ul data-bind="visible: showChildren, template: { name: 'itemTmpl', foreach: children }"></ul>
        </a>
    </li>
 </script>

Additionally, I adjusted the css slightly:

li ul li div:hover {
    background-color: #C0DDF0;
}

This modification appears to be successful http://jsfiddle.net/twTcw/

I hope this solution proves beneficial!

It appears that you have successfully implemented the solution. However, for a more streamlined approach with potentially reduced randomness in future updates, consider using the following code:


li ul li:hover {
    background-color: #C0DDF0;

Answer №4

To style elements in CSS:

ul li ul li.hover {
    background-color: #C0DDF0;
}

You should use the above code instead of:

ul li ul li:hover {
    background-color: #C0DDF0;
}

For JavaScript (jQuery) functionality, write the following:

$("ul li ul li","#pnlDestinations").live("mouseenter", function() {
    $(this).addClass("hover").siblings("li").removeClass("hover");
}).live("mouseleave", function() {
    $(this).removeClass("hover");
});

By implementing this code, you can achieve cross-browser compatibility for your script. Please refer to the updated script here. Since your original example script doesn't include any sub-lists, it will not work as expected. However, if you want to see a working demonstration version, you can access it here.
