A different approach without using regular expressions  Supports  hash  anchors at the end of the url as well as multiple question mark charcters      Should be slightly faster than the regular expression approach   function setUrlParameter url  key  value      var parts   url split      2   anchor   parts length  gt  1         parts 1          var query    url   parts 0   split      2     if  query length     1       return url         key         value   anchor     for  var params   query query length - 1  split   amp     i   0  i  lt  params length  i        if  params i  toLowerCase   startsWith key toLowerCase                 return params i    key         value  query query length - 1    params join   amp     query join        anchor     return url     amp     key         value   anchor

window location search is read write   However - modifying the query string will redirect the page you re on and cause a refresh from the server   If what you re attempting to do is maintain client side state  and potentially make it bookmark-able   you ll want to modify the URL hash instead of the query string  which keeps you on the same page  window location hash is read write   This is how web sites like twitter com do this   You ll also want the back button to work  you ll have to bind javascript events to the hash change event  a good plugin for that is http   benalman com projects jquery-hashchange-plugin

I wrote the following function which accomplishes what I want to achieve   function updateQueryStringParameter uri  key  value      var re   new RegExp      amp       key          amp        i      var separator   uri indexOf          -1     amp            if  uri match re         return uri replace re    1    key         value     2          else       return uri   separator   key         value

I have expanded the solution and combined it with another that I found to replace update remove the querystring parameters based on the users input and taking the urls anchor into consideration   Not supplying a value will remove the parameter  supplying one will add update the parameter  If no URL is supplied  it will be grabbed from window location  function UpdateQueryString key  value  url        if   url  url   window location href      var re   new RegExp      amp       key          amp              gi            hash       if  re test url             if  typeof value      undefined   amp  amp  value     null                return url replace re    1    key         value     2 3                       else               hash   url split                   url   hash 0  replace re    1 3   replace    amp                          if  typeof hash 1       undefined   amp  amp  hash 1      null                    url          hash 1                             return url                      else           if  typeof value      undefined   amp  amp  value     null                var separator   url indexOf          -1     amp                      hash   url split                   url   hash 0    separator   key         value              if  typeof hash 1       undefined   amp  amp  hash 1      null                    url          hash 1                             return url                    else               return url                      Update  There was a bug when removing the first parameter in the querystring  I have reworked the regex and test to include a fix   Second Update  As suggested by  Jar  nBarends - Tweak value check to check against undefined and null to allow setting 0 values  Third Update  There was a bug where removing a querystring variable directly before a hashtag would lose the hashtag symbol which has been fixed  Fourth Update  Thanks  rooby for pointing out a regex optimization in the first RegExp object  Set initial regex to     amp    due to issue with using      amp   found by  YonatanKarni  Fifth Update  Removing declaring hash var in if else statement

There are a lot of awkward and unnecessarily complicated answers on this page  The highest rated one   amateur s  is quite good  although it has a bit of unnecessary fluff in the RegExp  Here is a slightly more optimal solution with cleaner RegExp and a cleaner replace call   function updateQueryStringParamsNoHash uri  key  value      var re   new RegExp      amp       key        amp       i      return re test uri           uri replace re    1    key         value           uri   separator   key         value         As an added bonus  if uri is not a string  you won t get errors for trying to call match or replace on something that may not implement those methods   And if you want to handle the case of a hash  and you ve already done a check for properly formatted HTML   you can leverage the existing function instead of writing a new function containing the same logic   function updateQueryStringParams url  key  value        var splitURL   url split           var hash   splitURL 1       var uri   updateQueryStringParamsNoHash splitURL 0        return hash    null   uri   uri         hash      Or you can make some slight changes to  Adam s otherwise excellent answer   function updateQueryStringParameter uri  key  value      var re   new RegExp      amp       key        amp        i      if  re test uri         return uri replace re    1    key         value       else       var matchData   uri match                         var separator        test uri      amp                  return matchData 0    separator   key         value    matchData 1

Update  2020   URLSearchParams is now supported by all modern browsers  The URLSearchParams utility can be useful for this in combination with window location search  For example  if   URLSearchParams  in window        var searchParams   new URLSearchParams window location search       searchParams set  quot foo quot    quot bar quot        window location search   searchParams toString       Now foo has been set to bar regardless of whether or not it already existed  However  the above assignment to window location search will cause a page load  so if that s not desirable use the History API as follows  if   URLSearchParams  in window        var searchParams   new URLSearchParams window location search      searchParams set  quot foo quot    quot bar quot        var newRelativePathQuery   window location pathname         searchParams toString        history pushState null      newRelativePathQuery      Now you don t need to write your own regex or logic to handle the possible existence of query strings  However  browser support is poor as it s currently experimental and only in use in recent versions of Chrome  Firefox  Safari  iOS Safari  Android Browser  Android Chrome and Opera  Use with a polyfill if you do decide to use it

Yeah I had an issue where my querystring would overflow and duplicate  but this was due to my own sluggishness  so I played a bit and worked up some js jquery actualy sizzle  and C  magick   So i just realized that after the server has done with the passed values  the values doesn t matter anymore  there is no reuse  if the client wanted to do the same thing evidently it will always be a new request  even if its the same parameters being passed  And thats all clientside  so some caching cookies etc could be cool in that regards   JS     document  ready function                      ser   click function                      SerializeIT                                function SerializeIT                     var baseUrl                       baseUrl   getBaseUrlFromBrowserUrl window location toString                     var myQueryString                       funkyMethodChangingStuff      whatever else before serializing and creating the querystring                 myQueryString       fr2   serialize                    window location replace baseUrl         myQueryString                             function getBaseUrlFromBrowserUrl szurl                    return szurl split      0                              function funkyMethodChangingStuff                     do stuff to whatever is in fr2                             HTML    lt div id  fr2  gt      lt input type  text  name  qURL  value  http   somewhere com    gt      lt input type  text  name  qSPart  value  someSearchPattern    gt   lt  div gt   lt button id  ser  gt Serialize  and go play with the server  lt  button gt    C        using System Web      using System Text      using System Collections Specialized       public partial class SomeCoolWebApp   System Web UI Page               string weburl   string Empty          string partName   string Empty           protected void Page Load object sender  EventArgs e                        string loadurl   HttpContext Current Request RawUrl              string querySZ   null              int isQuery   loadurl IndexOf                   if  isQuery    -1                       If There Was no Query                           else if  isQuery  gt   1                    querySZ    isQuery  lt  loadurl Length - 1    loadurl Substring isQuery   1    string Empty                  string   getSingleQuery   querySZ Split                       querySZ   getSingleQuery 0                    NameValueCollection qs   null                  qs   HttpUtility ParseQueryString querySZ                    weburl   qs  qURL                    partName   qs  qSPart                      call some great method thisPageRocks weburl partName   or whatever                               Okay criticism is welcome  this was a nightly concoction so feel free to note adjustments   If this helped at all  thumb it up  Happy Coding    No duplicates  each request as unique as you modified it  and due to how this is structured easy to add more queries dynamicaly from wthin the dom
