start/play embedded (iframe) youtube-video on click of an image

Solution 1:

The quick and dirty way is to simply swap out the iframe with one that has autoplay=1 set using jQuery.

THE HTML

Placeholder:

<div id="videoContainer">
  <iframe width="450" height="283" src="https://www.youtube.com/embed/VIDEO_ID_HERE?wmode=transparent" frameborder="0" allowfullscreen wmode="Opaque"></iframe>
</div>

Autoplay link:

<a class="introVid" href="#video">Watch the video</a></p>

THE JQUERY

The onClick catcher that calls the function

jQuery('a.introVid').click(function(){
  autoPlayVideo('VIDEO_ID_HERE','450','283');
});

The function

/*--------------------------------
  Swap video with autoplay video
---------------------------------*/

function autoPlayVideo(vcode, width, height){
  "use strict";
  $("#videoContainer").html('<iframe width="'+width+'" height="'+height+'" src="https://www.youtube.com/embed/'+vcode+'?autoplay=1&loop=1&rel=0&wmode=transparent" frameborder="0" allowfullscreen wmode="Opaque"></iframe>');
}

Solution 2:

You can do this simply like this

$('#image_id').click(function() {
  $("#some_id iframe").attr('src', $("#some_id iframe", parent).attr('src') + '?autoplay=1'); 
});

where image_id is your image id you are clicking and some_id is id of div in which iframe is also you can use iframe id directly.

Solution 3:

To start video

var videoURL = $('#playerID').prop('src');
videoURL += "&autoplay=1";
$('#playerID').prop('src',videoURL);

To stop video

var videoURL = $('#playerID').prop('src');
videoURL = videoURL.replace("&autoplay=1", "");
$('#playerID').prop('src','');
$('#playerID').prop('src',videoURL);

You may want to replace "&autoplay=1" with "?autoplay=1" incase there are no additional parameters

works for both vimeo and youtube on FF & Chrome

Solution 4:

Example youtube iframe

<iframe id="video" src="https://www.youtube.com/embed/xNM7jEHgzg4" frameborder="0"></iframe>

The click to play HTML element

<div class="videoplay">Play</div>

jQuery code to play the Video

$('.videoplay').on('click', function() {
    $("#video")[0].src += "?autoplay=1";
});
