I want to get the v=id from YouTube’s URL with JavaScript (no jQuery, pure JavaScript).
v=id
http://www.youtube.c
You don't need to use a regular expression for this.
var video_id = window.location.search.split('v=')[1]; var ampersandPosition = video_id.indexOf('&'); if(ampersandPosition != -1) { video_id = video_id.substring(0, ampersandPosition); }
