javascript get query string

try using this function:

function getParameterByName(name) {
    var url = window.location.href;
    name = name.replace(/[\[\]]/g, "\\$&");
    var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, " "));
}

Select allOpen in new window

alert( getParameterByName( 'queryStringName' ) );

What name I suppose to put in ?

I need to get all names that I may not even know in advance

can you use jquery?

this might do the trick:

function getQueryVariable()
{
       var query = window.location.search.substring(1);
       var vars = query.split("&");
       for (var i=0;i<vars.length;i++) {
               var pair = vars[i].split("=");
               alert( pair( 0 ] + ' = ' + pair[ 1 ] );
       }
       return(false);
}

Select allOpen in new window

I'm not sure what your question is. But it almost sounds as if you're struggling with the unknown quantity of names and creating variable names for each one. You could list the names as a group, separated by pipe characters.

response.html?firstnames=john|mary|george|susan 

Select allOpen in new window

Then you could alert the list of names as a group.

alert(window.location.search.substr(12).replace('|',', ','g') );

Select allOpen in new window

It would help if you could explain your objective a little more. URL query strings are intended to send information to the backend to be processed by the server using something like PHP or .NET. It is rare that javascript would be concerned with these.
