I have created an application for getting the url parameter values using JavaScript, the application is working fine but the problem is that when the param key is having space then i am getting undefined

my code is as given below

script

function getParameter(paramName )
{
 paramName = paramName.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
 var regex = new RegExp("[\\?&]" + paramName + "=([^&#]*)", 'i'), results = regex.exec(location.search);
 return results == null ? undefined : decodeURIComponent(results[1].replace(/\+/g, " "));
}

let say the url is like

http://localhost/myapp/index.html?User Id=145&Dept=HR

call

getParameter('Dept') ===> Gives HR
getParameter('User Id') ===> Gives undefined

can anyone please tell me some solution for this

Do you observe that you url http://localhost/myapp/index.html?User Id=145&Dept=HR actually is encoded into "http://localhost/myapp/index.html?User%20Id=145&Dept=HR" ?? – Manish Kr. Shukla Aug 23 '14 at 11:56
so i need to call like `getParameter('User%20Id')` – Alex Man Aug 23 '14 at 11:57
in IE its not working – Alex Man Aug 23 '14 at 12:00
This is a FAQ and duplicate http://stackoverflow.com/questions/979975/how-to-get-the-value-from-url-parameter – mplungjan Aug 23 '14 at 12:03
Also spaces are not normal in a parameter name – mplungjan Aug 23 '14 at 12:04
@mplungjan its not duplicate, here i am facing issues in getting param value whose param key is having space – Alex Man Aug 23 '14 at 12:05
@mplungjan actually its an external application url where url is having params like that – Alex Man Aug 23 '14 at 12:05
@AlexMan Then space should be encoded to `%20` – Rahil Wazir Aug 23 '14 at 12:07
