Need to pass a value from PHP to Javascript [duplicate]

Question

I need to pass a value from PHP back to my javascript. I have tried so many things but can't get it to work. Here is my code.

<script type="text/javascript">     
    life = {};
    life.anjaxEnter = function(finished) {
        $.ajax({
        dataType:"json",
        type:"POST",
        data:mydata,
        url:"myurl.php",
        async:false,
        success:life.receiveResult,
        });
        setTimeout("location.href='myredirectionurl'", 1000); // Redirect after 1 second
    }
    life.receiveResult = function(result) {
        alert(result);
    }   
</script>

I need to pass a specific value from the PHP file back to life.receiveResult and then add this to the redirection url.

Thanks for the help. I had seen answers as well, however, they did not seem to work for me. Got it working now though! — sethcarlton

The biggest problem is probably that at the time when you assign life.receiveResult to success, life.receiveResult is undefined. You need to define it before you assign it to something else.

myurl.php needs to return a JSON result when it's called. Something like this:

<?php
header("Content-Type: text/json");
$mydata = "Hello";
echo json_encode(array('ok' => true, 'mydata' => $mydata));
?>

Have a look at the json_encode docs, the header docs and some of the other answers for more information.
