[jQuery] Re: Auto update PHP session variables using Ajax/JQuery

[themba]

Thanks for the reply, Now I have another situation. I have decided to
use JSON with JQuery to send data to a php script, this works well,
however, I would like to add a please wait/loading message while this
is still executing please see my code below:


$().ready(function() {
  $("#limitBox").change(function () {
          var JSONObject = new Object;     ;
          JSONObject.datalimit = this.value;
          JSONObject.sessionVarName = 'data_limit';
          JSONstring = JSON.stringify(JSONObject);
          alert(JSONstring);
          $.get('parser.php?json=' + JSONstring,'', showDataTableResult,
"text");

    });


        function showDataTableResult(res)
        {
               $("#fullresponse").html("response: " +res);
        }


});


Thank you.
