Thease days, I study about WebRTC from https://bitbucket.org/webrtc/codelab But, I have some problem at step5. I can't resolve step5 bonus points number 5. Question is this : This app uses a JavaScript prompt to get a room name. Work out a way to get the room name from the URL, for example localhost:2013/foo would give the room name foo.
I used javascript window.location.pathname, but it didn't work. If you help me, I very appreciate it!
You can do like this:
var str = window.location.href;
var path = str.split('/');
var value = path[path.length-1]; //foo
pathname actually works.
<html>
<head>
<script>
alert(window.location.pathname);
</script>
</head>
<body>
</body>
</html>
you can use this code
var aarr = window.location.href.split('/');
//get last value
var id = aarr[aarr.length -1];
You can use lastIndexOf
since you're only concerned about getting one element instead of using split which would return all of them.
var url = "http://localhost:2013/foo";
console.log(url.substr(url.lastIndexOf('/') + 1)); // returns 'foo'
