I have a url

http://www.example.com/state=survey&action=display&survey=39&zone=surveys&currency=Denmark

A user will land on a new page with the above url. This page will include a form. There is an input with an id 'currencyrequired' - i want this input to automatically pull in the currency variable from the url (in this example Denmark).

<input type="text" id="currencyrequired" name="currencyrequired" size="40" maxlength="20" value="" class="input-pos-int">

The currency part of the url is likely to change as it depends upon which country they select so you could end up with - http://www.example.com/state=survey&action=display&survey=39&zone=surveys&currency=Norway

Ideally what i would like is to list all the currencies (8 in total) and the script would check what country is listed in the url and populate the currencyrequired input field with the output

Try this:

$("#currencyrequired").val(getParameterByName('currency'));

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

I tested it and it works on all browsers. Also your input element must end with /> – Elio Apr 24 at 11:30

Try this:

// Get the url parameter from location href
$.getCurrency= function(name){
    var results = new RegExp('[\\?&amp;]' + name + '=([^&amp;#]*)').exec(window.location.href);
    return results[1] || 0;
}

// Set the input text box value
$("#currencyrequired").val(decodeURIComponent($.getCurrency('currency')));

You could use location.search to return the query string and do:

var url = location.search;
var country = url.substring(url.indexOf('currency=')+9, url.length);

$("#input").val(country);

That will only work if currency=Denmark is the last information in the URL. – TryingToImprove Apr 24 at 9:30
This works in the jsfiddle but when i aste the code into my page it doesnt do anything. – R4N_S_S Apr 24 at 10:13
@R4N_S_S - do you have jquery defined on your page? Try adding an alert. alert(country); - does the alert work? – Darren Davies Apr 24 at 10:16
The currency part of the url is likely to change as it depends upon which country they select so you could end up with - example.com/… – R4N_S_S Apr 24 at 10:25
@Darren - yes jquery is present on the page. the alert works - thanks in advance – R4N_S_S Apr 24 at 10:30
