Angular Controller encounters issue with event handler functionality ceasing

One of my Angular controllers has the following line. The event handler works when the initial page loads, but it stops working when navigating to a different item with the same controller and template.

        document.getElementById('item-details-view').addEventListener('touchstart', toggleshowoption, false);

UPDATE:

Attempting a directive solution:

app.directive('slideShowMenu', function () {
return {
    link: function ($scope, $element, $attrs) {

        var visible = false;

        function toggleshowoption() {
            if (!visible) {
                $(".slideshow-controls").css({"visibility": "visible", "opacity": "1"});
                visible = true;
            }
            else {
                $(".slideshow-controls").css({"visibility": "hidden", "opacity": "0"});
                visible = false;
            }
        }
        $element.addEventListener('touchstart', toggleshowoption, false);
    }
}
});

Encountering this error message:

undefined is not a function (evaluating '$element.addEventListener('touchstart', toggleshowoption, false)')

Answer №1

Each element must have a unique identifier - my hunch is that angular may be rendering the template twice, resulting in two elements with identical ids. Consider switching to using classes instead.
