Question

I need a js code for always getting the server time in a webpage. This code is working but not get the time dynamically. Code gets time one time while webpage loading.

$(document).ready(function() {

               $.ajax({
                    type: "POST",
                    url: "GenericWCF.svc/GetSystemTime",
                    data: "{}",
                  contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function(bs) {
                        $("#systemTime").text(bs.d);
                  }
               });

});

You need to use the window.setInterval method to call your function which performs your ajax call.

The window.setInterval method calls a function every X milliseconds repeatedly, until a call to window.clearInterval is called. Note that window.setInterval is “standard” javascript rather than jQuery.

For example:

window.setInterval('yourfunction()', 1000);

function yourfunction()
{
   // your ajax call here.
}

Will call your ajax function every 1000 milliseconds (every second).
