In this article I will explain with an example, how to convert YouTube URL (Link) to embed URL (Code).
This article will explain how to play (embed) YouTube Videos in HTML Page using:
1. IFRAME element.
2. EMBED element.
 
 
Convert YouTube URL (Link) to Embed URL(Code) using IFRAME element
The following HTML Markup consists of an HTML TextBox, a Button and an IFRAME element.
The Button has been assigned a jQuery click event handler. When the Button is clicked, first the YouTube Video URL is fetched from the TextBox and then YouTube Video ID is extracted from the URL.
The extracted YouTube Video ID is appended to the YouTube embed video URL and the URL is set to the SRC property of the HTML IFRAME element.
<input type="text" id="txtUrl" style="width: 300px" />
<input type="button" id="btnPlay" value="Play" />
<hr />
<iframe id="video" width="420" height="315" frameborder="0" style="display: none"
    allowfullscreen></iframe>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    $("body").on("click", "#btnPlay", function () {
        var url = $("#txtUrl").val();
        url = url.split('v=')[1];
        $("#video")[0].src = "https://www.youtube.com/embed/" + url;
        $("#video").show();
    });
</script>
