    regex - Split URL in javascript at last instance of '&' - Stack Overflow

    programmeradmin0浏览0评论

    I saw a bunch of URL splitting techniques on this site but could find one for what i need.

    I need the last parameter chopped off.

    ie. .aspx?k=website&cs=This%20Site&u=http%3A%2F%2Fwww.website%2FOur-Commitment

    to

    .aspx?k=website&cs=This%20Site

    The URL will not always be the same and so the solution must somehow search for the last "&" and strip it off.

    I managed to do this but i was hoping for less lines:

    rewriteURL();  

function rewriteURL() {
    var url = window.location;
    var urlparts = url.split(/[\s&]+/);
    var newURL = urlparts[0] + '&' + urlparts[1];
    window.location.href = newURL;
}

    • 1 Wouldn't it be better to not rely on order of the parameters and actually remove a specific named parameter? – jfriend00 Commented Oct 31, 2011 at 20:04

    Reset to default 4 
    function rewriteURL() {
  window.location.href = window.location.href.substring(0, window.location.href.lastIndexOf('&'));
}

    var loc = window.location + '';
var url = loc.substring(0, loc.lastIndexOf('&'));

    window.location is not a string.

    The answer by @thejh is better, but for a fun one-liner:

    var newLoc = location.href.split('&').slice(0,-1).join('&');
// "http://www.website./Pages/SearchResultsPage.aspx?k=website&cs=This%20Site"

    function rewriteURL() {
    var urlparts = window.location.href.split(/[\s&]+/);
    window.location.href = urlparts[0] + '&' + urlparts[1];
}

    (Point is, does it matter that much?)

    My bigger concern would be that I'd be afraid the parameter order might change, or there'd be additional parameters, etc. Better to do it right and be certain.
