分离youtube链接以仅检索ID，并将ID传递给另一个变量[duplicate]

Question

This question already has an answer here:

• How do I get the YouTube video ID from a URL? 33 answers

I have looked on ways like .split() to seperate strings and saw a simple seperation like .split(""), or .split("") but i don't know how to do more complex like remove everything before and after the id. What i have is a variable that contains a youtube string example:

var utubeLink = "http://img.youtube.com/vi/8lmuuaI09ro/0.jpg";

and a variable that is waiting to store the ID of the var utubeLink

var newutubeLink = "http://www.youtube.com/v/"

I want to remove everything so that i get 8lmuuaI09ro, and pass the ID into newutubeLink so that my final result will be http://www.youtube.com/v/8lmuuaI09ro.

Thanks

Use something like this, if the patterns of the URL doesn't change.

var utubeLink = "http://img.youtube.com/vi/8lmuuaI09ro/0.jpg";
var newutubeLink = "http://www.youtube.com/v/";
var parts = utubeLink.split('/');
var link = newutubeLink + parts[4];
console.log(link);
