Javascript Question

run click and double click on a anchor tag

I am trying to perform two actions when a user clicks on a anchor tag. The anchor tag will have a video link. The idea was when a user click once on the anchor tag the url will open in new window and when a user will double click on the tag then it will use the html5 download attribute to initiate the download.

<a class="movie-media-download-link" href="http://example.com/video.mp4" download=""></a>


jQuery(document).on("click", ".movie-media-download-link", function(e) {
e.preventDefault();
// window.location.href = jQuery(this).attr('href');
});
jQuery(document).on("dblclick", ".movie-media-download-link", function(e) {
jQuery('.movie-media-download-link').unbind('click');
});


When in use prevent default in click then in double click the download attribute of html5 stops working. Even in i unbind the event then also it does not works.

Answer

You'll have to create the doubleclick functionality yourself, and use a delay for the regular click to check if it was actually a double click etc.

jQuery(document).on("click", ".movie-media-download-link", function(e) {
    e.preventDefault();

    var self = this, time = 500;

    if ($(this).data('flag')) {
        clearTimeout($(this).data('timer'));
        var a = document.createElement('a');
            a.href = self.href;
            a.download = "";
            a.click();
    } else {
        $(this).data('timer', setTimeout(function() {
            window.location.href = jQuery(self).attr('href');
        }, time));
    }

    $(this).data('flag', true);

    setTimeout(function() {
        $(self).data('flag', false);
    }, time);
});

<a class="movie-media-download-link" href="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" download="">Click once to play, twice to download !</a>
