  • I'm trying to run this code so I can have an image galley with limiters at the top. Each image will open an URL.

    // Add active class to the current button (highlight it)
    var btnContainer = document.getElementById("myBtnContainer");
    var btns = btnContainer.getElementsByClassName("btn");
    for (var i = 0; i < btns.length; i++) {
    btns[i].addEventListener("click", function(){
    var current = document.getElementsByClassName("active");
    current[0].className = current[0].className.replace(" active", "");
    this.className += " active";
    });
    }

    It works on my computer when I save it as a .html file, but not when I use HTML to upload it to ModX. When I click on the limiter, nothing happens in ModX.
