jQuery querystring [duplicate]

Answer 1

Use the function listed in the answer to this question:

function getParameterByName( name )
{
  name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
  var regexS = "[\\?&]"+name+"=([^&#]*)";
  var regex = new RegExp( regexS );
  var results = regex.exec( window.location.href );
  if( results == null )
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}

And then just do something like this:

var qParam = getParameterByName('q');
$('#mytextbox').val(qParam);

Answer 2

In my programming archive I have this function:

function querystring(key) {
   var re=new RegExp('(?:\\?|&)'+key+'=(.*?)(?=&|$)','gi');
   var r=[], m;
   while ((m=re.exec(document.location.search)) != null) r.push(m[1]);
   return r;
}

You can use that to get the query string value and put in a textbox:

$('#SomeTextbox').val(querystring('q'));
