如何在php中的更改事件上的文本框上设置Session变量

Question

I want to update my session variables on textbox's onchange event, without page reload How to do that.?? thanks!

Answer 1

I would use on blur, that way it wont set the variable everytime the user types, only when he clicks somewhere else....

$('textbox').blur(function(){
  var thevalue = $(this).val();

 $.ajax({
    url:'yoururl.php',
    type: "post",
    data:{"value":thevalue},
    dataType:"html",
    success:function(data){
        console.log(data);
    } 
 });
});

THen in your php...

<?php
   $_SESSION['yoursessionkey'] = $_POST['value'];
   echo "success";

?>
