v is a query parameter  technically you need to consider cases ala  http   www youtube com watch p DB852818BF378DAC amp v 1q-k-uN73Gk  In  NET I would recommend to use System Web HttpUtility ParseQueryString  HttpUtility ParseQueryString url   v      And you don t even need to check the key  as it will return null if the key is not in the collection

I use seperate custom functions which gets all URL Parameters and URL parts   For URL parameters   which is the final part of an URI String  http   domain tld urlpart  x a amp y b       function getUrlVars         var vars           var parts   window location href replace     amp        amp         amp     gi  function m key value            vars key    value              return vars          The above function will return an array consisting of url variables   For URL Parts or functions   which is http   domain tld urlpart  x a amp y b I use a simple uri split   function getUrlParams          var vars           var parts   window location href split            return parts      You can even combine them both to be able to use with a single call in a page or in javascript

Why dont you take the string and split it   Example on the url  var url    http   www youtube com watch p DB852818BF378DAC amp v 1q-k-uN73Gk    you can do a split as  var params   url split      1  split   amp       You will get array of strings with params as name value pairs with     as the delimiter
