Modifying the background color of a specific link's CSS when navigating to that webpage

Hello everyone, I'm attempting to change the background color of a specific link in my navigation bar to a different color when the user is on the corresponding page. Here's the code snippet I've been trying to use:

$("#nav li ul li a #changeBG1").css("background-color","red");

Here is a snippet of the HTML for the navigation bar:

<ul id="nav">
    <li><a href="index.php">home</a></li>
    <li><a href="custHelp.php">who we are</a>
    <ul>
        <li id="changeBG1"><a href="about.php">about</a></li>
        <li id="changeBG2"><a href="help.php">team</a></li>
    </ul>
</li>

Unfortunately, this code changes all links with the ID "changeBG1" in the navigation bar instead of just the one I want. I'm struggling to figure out how to target only that specific link within the navigation bar.

Here is the JQuery code I have so far:

var url = window.location.href;

url = url.substr(url.lastIndexOf("/") + 1);
$("#theNav").find("a[href='" + url + "']").addClass("theNavsBG");

if (url == 'about.php'){
    $("#nav li ul li a #changeBG1").css("background-color","red");
}

Any assistance would be greatly appreciated. Thank you!

Answer №1

To indicate the current page on a website, I would create a CSS class and then apply it to the specific link using jQuery. This way, the user can easily identify which page they are currently viewing.

Here is an example of the CSS:

.active {
   background-color: blue;
}

And here is the jQuery code:

var currentUrl = window.location.href;
currentUrl = currentUrl.substr(currentUrl.lastIndexOf("/") + 1);

$("#navigation li a").removeClass('active');
$("a[href='" + currentUrl + "']").addClass('active');

Answer №2

Here is a suggestion to change the background color to red:

$("#changeBG1").css("background-color","red");

Using the id selector is the most efficient way, without adding unnecessary "stuff".

If you want, you can also assign a class to the li:

$("#changeBG1").addClass('foo');

Overall, it seems like your selector should be as follows:

$("#nav li ul li#changeBG1").css("background-color","red");

Simplify your life with this code snippet...

.active{
    background-color: red;
}​

Implement the following code...

$("#nav a[href$='" + url + "']").addClass("active");

This script identifies the link that ends with the specified string in the URL and applies a CSS class to that anchor tag. If you wish to style the parent element, use the .parent() method.

$("#nav a[href$='" + url + "']").parent().addClass("active");
