I have used this awesome post in the post for getting query string data from the URL: How can I get query string values in JavaScript?

However, i am now in a situation where the query string values are base64 encoded, e.g:

"param1": "yA26LZ6+SxFEgNuF86/SIXfimGlg="
"param2": "f4x0Dh*6iZCXtX8nhiSb3xahNxrg="

I've done some research and apparently this regex can handle base64:

^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$

How can i adapt the function to incorporate this regex?

What i am trying to do is create a JavaScript function that looks are the URL, can gets the value for a particular paramter:

wwww.mydomain.net/reset.html?param1=76+hgfh5464/rte69&?userId=23243*--++/231\

Here you cans see 2 parameters:

param1
userId

You seem to have forgotten to include what you are actually trying to do. Are you checking a string to see if it is base64 encoded? –  Anonymous yesterday
    
How can i adapt the function to incorporate this regex - I'm not sure what you're asking. In what way incorporate it? What have you tried so far, other than copying/pasting code from elsewhere. –  RGraham yesterday
    
I believe he's trying to get Base64 query string values out of the string, but presumably the Base64 = padding is breaking the standard regex. I'm not sure query strings support having values with = in them. –  Evan Knowles yesterday
