2nd Update  In attempt to provide a comprehensive answer  I am benchmarking the three methods proposed in the various answers   var testURL     Products List SortDirection dsc amp Sort price amp Page 3 amp Page2 3   var i      Testing the substring method i   0  console time  10k substring    while  i  lt  10000        testURL substring 0  testURL indexOf            i      console timeEnd  10k substring        Testing the split method i   0  console time  10k split    while  i  lt  10000        testURL split      0        i      console timeEnd  10k split        Testing the RegEx method i   0  var re   new RegExp           console time  10k regex    while  i  lt  10000        testURL match re  0        i      console timeEnd  10k regex      Results in Firefox 3 5 8 on Mac OS X 10 6 2   10k substring   16ms 10k split       25ms 10k regex       44ms   Results in Chrome 5 0 307 11 on Mac OS X 10 6 2   10k substring   14ms 10k split       20ms 10k regex       15ms   Note that the substring method is inferior in functionality as it returns a blank string if the URL does not contain a querystring  The other two methods would return the full URL  as expected  However it is interesting to note that the substring method is the fastest  especially in Firefox     1st UPDATE  Actually the split   method suggested by Robusto is a better solution that the one I suggested earlier  since it will work even when there is no querystring   var testURL     Products List SortDirection dsc amp Sort price amp Page 3 amp Page2 3   testURL split      0         Returns    Products List   var testURL2     Products List   testURL2 split      0         Returns    Products List      Original Answer   var testURL     Products List SortDirection dsc amp Sort price amp Page 3 amp Page2 3   testURL substring 0  testURL indexOf              Returns    Products List

This may be an old question but I have tried this method to remove query params  Seems to work smoothly for me as I needed a reload as well combined with removing of query params   window location href   window location origin   window location pathname    Also since I am using simple string addition operation I am guessing the performance will be good  But Still worth comparing with snippets in this answer

An easy way to get this is   function getPathFromUrl url      return url split      0       For those who also wish to remove the hash  not part of the original question  when no querystring exists  that requires a little bit more   function stripQueryStringAndHashFromPath url      return url split      0  split      0       EDIT   caub  originally  crl  suggested a simpler combo that works for both query string and hash  though it uses RegExp  in case anyone has a problem with that    function getPathFromUrl url      return url split         0
