使用jQuery每隔xy秒执行一次PHP脚本

Question

I have a program that is calling a separate php script that is generating google map markers, that need to be placed onto google map. The thing that I would like to do is to place that php include into jquery so that it would get executed every xy seconds.

So basically, how to get this:

<?php include('buildmarkers.inc.php') ?>

to execute every xy seconds with jquery?

Answer 1

Do something like this

setInterval(function(){ 
 $.ajax({url: "url of php script", success: function(result){
       Do whatver you want to do with output.
    }});
}, 3000);

Note 3000 is milliseconds

Answer 2

Use setTimeout to avoid overlapping issue with setInterval
This method will execute ajax loop every 3 seconds after success or error callback

var ajaxLoop=function(delay){
  $.ajax({
         url: 'someURL',
         success: function(result){
           //success 
           setTimeout(ajaxLoop, delay);
        },
        error: function(err){
           //error occurred 
           setTimeout(ajaxLoop, delay);
        } 
  });
}

ajaxLoop(3000);  // delay = 3000
