I have a button named searchReportButton. On this button click, I need to check session value from server using a ajax web method "Error.aspx/CheckSessionExpiry".This is done in checkSession javascript function. The checkSession is not returning anything now - instead it is handling the required operation based on the result (redirecting to error page).

I need to return the result of ajax web method to the Main Caller. How can we do this return?

Main Caller

searchReportButton.click(function () {

    checkSession();
    //Remainging Code

});

Helper

function checkSession() {

var win = 101;
$.ajax(
        {
            type: "POST",
            url: "Error.aspx/CheckSessionExpiry",
            data: '{"winNumber": "' + win + '"}',
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: handleSessionResult

        }
        );
        }

Result Helper

  function handleSessionResult(result) {


    if (result.hasOwnProperty("d")) 
    {
      result = result.d
    }

    if (result == "ACTIVE") 
    {
      window.location.href("Error.aspx");
      return false;
    }

   //alert(result);

}
