php - Retry Ajax Request 5 Times with 1 Second Interval -


i have verify.php file check database entry , return 1 if exists or 0 if doesn't. database updated between 0 5 seconds. @ least first 5 seconds return might 0.

in page, want check verify.php's return ajax , retry 5 times 1 second interval between each checks. if @ time in 5 second check, received 1, exit checking loop , display success message.

i have written checks once , don't know how make check x amount of times:

<p id="status"></p> <script type="text/javascript"> var url = 'verify.php'; $('#status').text('please wait...');  $(document).ready(function(){ $.ajax({     type: 'post',     url:url,     success: function(msg){         if (msg == 1){             $('#status').text('success');         }else{             $('#status').text('failed');         }     } }); }); </script>

any appreciated. thanks.

  • turn ajax call function
  • have variable tracks how many tries have
  • call ajax function in own callback delay of 1 second if needed, is, haven't exhausted tries , status wrong.

code

var tries = 0;     function getstatus() {   $.ajax({     type: 'post',     url: url,     success: function(msg){       tries++;       if (msg == 1){          $('#status').text('success');       } else {           if (tries >= 5 ) {             $('#status').text('failed');           } else {              settimeout(getstatus, 1000);           }       }     }   }); }
