Extract a part from URL in Javascript [duplicate]

Question

I have a string:

http://a.long.url/can/be/here/jquery.min.js?207

I need to extract the base URL http://a.long.url/can/be/here/ using Javascript. So it should be split on the first / from the right.

try with this

var url = 'http://a.long.url/can/be/here/jquery.min.js?207';
var path = url.split( '/' );
var stripped = "";
for ( i = 0; i < path.length-1; i++ ) {
    if(i>0) stripped += "/";
    stripped += path[i];
}
alert(stripped)

url.substring(0, url.lastIndexOf("/") + 1)

Remove the + 1 if you don't want the / in the end.

Note that this returns an empty string if the url does not contain a /, e.g. if it's simply www.mydomain.com.

var url = "http://my.com:8080/path/bob.js?query"

var col1 = url.indexOf("?");
if (col1 > 0) {
    var col = url.substring(0,col1).lastIndexOf("/");
} else {
    col = url.lastIndexOf("/");
}

var extracted = url.substring(0, col);

Without checking for errors. (For example, what if the url string has no slashes at all. It's not a valid URL but it could be passed to this code.) Note also that it doesn't work if the question mark is the first character.
