Question

I’m trying to make a very simple query:

$.ajax({
        url: "ajaxfunc.php",
        dataType: 'json',
        success: function(data){
        alert(data.resp);
    }
});

And in ajaxfunc.php I have

<?php echo json_encode(array("resp"=>"1")); ?>

But for a strange reason data is always null and data.resp is undefined.

Where can be the problem?

Answer 1

i got this working in my system.

<script language="javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js"></script>
<script language="javascript">
$(document).ready(function(){

$.ajax({
    url: "b.php",
    async:false,
    dataType: 'json',
    success: function(data){
    alert(data.resp);
}
});

                       });
</script>

b.php

<?php 

$k['resp'] = 66;
echo json_encode($k);

?>
