getwindowname() function have created in controller, , returns value of "windowname" key session object. how can read value in above javascript?

you can write controller method that:

public actionresult getwindowname() {   session["windowname"] =      guid.newguid().tostring().replace("-", "");   return json(session["windowname"].tostring()); }

then call through ajax:

$.get('@url.action("getwindowname")', function(data){     if(window.name != data) {         // need here     } })
