CSS not reflecting changes after the href of the <link> tag has been updated

Hey there, I'm a beginner in the world of programming and currently facing an issue that I need help with. My goal is to dynamically update the CSS of my webpage by using JQuery to change the 'href' value in the link tag.

In order to test this functionality, I am working on a simple testcase while utilizing Less for CSS. Within my project, I have 2 .less files ('test.less' & 'testTwo.less'). Below is the code snippet:

$(function() {

    $('#changeButton').click(function() {
    $('#style').attr('href', '../testfiles/testTwo.less');
    console.log($('#style').attr('href'));
    })

    })

During testing, I verify if the href value actually changes, which it does successfully. However, the styling of the page remains unaffected.

<!DOCTYPE HTML>
<html>
<head>
    <link rel="stylesheet/less" type="text/less" href="../testfiles/test.less" id="style">
    <script type="text/javascript" src="../jquery/jquery.js"></script>
    <script type="text/javascript" src="test.js"></script>
</head;

<body>
    <div id="changeButton">click me</div>

    <script src="../bower_components/less/dist/less.js"></script>
</body>

</html>

I understand that there might be something crucial missing from my approach, possibly related to CSS rendering. Any guidance or assistance would be greatly appreciated. Thank you!

Answer №1

Make sure to incorporate the changes into your code as shown below

$(function() {

    $('#changeButton').click(function() {
        $('#style').attr('href', '../testfiles/testTwo.less');
        console.log($('#style').attr('href'));
        $('style[id^="less:"]').remove(); // don't forget to remove the less
        less.refresh(); // make sure to refresh the files
    })

})

Important Notes

  1. Consider using css in html instead of less for better performance. You can use pre compilers and have html refer to css.
  2. Remember that Less compiler does not automatically compile dynamically added files. You must manually trigger the refresh to apply changes.
  3. Removing the less file is necessary due to how LESS operates. It processes the less file, then adds a style attribute with id like
    id='less:<<NAME OF YOUR LESS FILE>>'

Answer №2

When utilizing less.js, it is necessary to ensure that all less files are loaded before it can compile them into css during the page load process. If the less file is added dynamically, it will not have the opportunity to be compiled.
