Retrieving query string in sharepoint add-ins

Question

I'm developing a Sharepoint 2013 Add-in, and I need to retrieve the query string of the original request.

Users are linked to our add-ins from emails and we need to provide some context. The add-in is requested like this: https://x.sharepoint.com/MyAddIn?p=10

Is it possible to retrieve the value of p in my add-in?

Answer 1

You could use the following code snippet:

Uri myurl = new Uri(Request.QueryString["SPHostUrl"]);
string param1 = HttpUtility.ParseQueryString(myUri.Query).Get("p");

or use

string param1 = Request.QueryString["p"];

If you want to this via JS, then go on with this

 function getQueryStringParameter(paramToRetrieve) {         
     var params;         
     var strParams;           
     params = document.URL.split("?")[1].split("&");         
     strParams = "";         
     for (var i = 0; i < params.length; i = i + 1) {             
         var singleParam = params[i].split("=");             
         if (singleParam[0] == paramToRetrieve)
             return singleParam[1];         
     }     
 }     

 var sProp = decodeURIComponent(getQueryStringParameter("StringProperty1"));     
 document.write('Value of StringProperty1 : ' + sProp + '</br>');
