Encode query string in url

Question

window.btoa(str);   // for encoding any string

window.atob(enc);   // for decoding any encoded string

 

on 1st page, where we pas query string

 

var qstring = "&projectname=" + window.btoa(projectData[t][1].v) + "&account=" + window.btoa(projectData[t][4].v) + "&pcode=" + window.btoa(projectData[t][0].v) + "&ced=" + window.btoa(projectData[t][13].fv) + "&pract=" + window.btoa(projectData[t][9].v) ;

var link = "[site url]" + qstring;

 

on 2nd page, where query string variable is fetched

 

//First we must call the EnsureSetup method

JSRequest.EnsureSetup();

//Get a query string parameter called Id. i.e - "page.aspx?Id=11" will return 11

var account = JSRequest.QueryString["account"];

var projectName = JSRequest.QueryString["projectname"];

var contractEndDate = JSRequest.QueryString["ced"];

var pcode = JSRequest.QueryString["pcode"];

var pract = JSRequest.QueryString["pract"];

var acnt = window.atob(account);

var pName = window.atob(projectName);

var pCode = window.atob(pcode);

var ced = window.atob(contractEndDate);

var practice = window.atob(pract);
