Why different php session value in Chrome and FireFox?-CodePudding

set a session value to 10 by ajax. In Chrome it will set back to ZERO. Why?? my.php

<?php
session_start();
$_SESSION["temp"] = 0; ?>


<div id="t">$_SESSION["temp"] = <?=$_SESSION["temp"]?> <br></div>
<br><input type="button" value="Plus 5" onclick="javascript:plusn(5);">
<script>
    function plusn(n) {
          $.ajax({
              url: 'myajax.php?n=' n,
              type: 'get',
              async: false,
              success:function(result){
                  $("#t").append(result)
              }
          });
    }
    
    $(document).ready(function() {
        plusn(10); //initial add 10
    })
</script>

myajax.php

<?php
session_start();
$_SESSION["temp"]  = $_GET["n"];
exit('$_SESSION["temp"] = '.$_SESSION["temp"].'<br>');
?>

place here:

CodePudding user response：

It works correctly when I send it with a 1000 millisecond delay but this is not a correct solution I will continue to investigate.

setTimeout(()=>{
        plusn(10);
    },1000)
