Ajax method of making local real-time updating data in JSON format

Not much nonsense, on the code, front desk:

The main use of the dead loop one second to read the JS once to refresh the page (recursive idea) separately to ShowData this div data to refresh

, the individual feels that it needs to be optimized. Ask the great God for guidance

<script type="Text/javascript">$ (function () {vari =0; function Settimeoutpost () {$.ajax ({type:"Post", URL:"/usercontrol/dodata.ashx", DataType:"JSON", Success:function (msg) {$ ("#ShowData"). HTML (msg[0].getinfo+i++); SetTimeout (Settimeoutpost, +);                            }, Error:function (req) {alert (req.readystate);                    }                        });                } settimeoutpost ();                           }); </script>

Background main code:

1. The naming format for the header is JSON

" Application/json ";

2. Returns a JSON-stitched string that might later be optimized to write a JSON class to generate JSON-formatted data

string " [{\ "getinfo\": \""+info[0]+"\"}] " ;                Context. Response.Write (obj);
