I'm trying to retrieve data from a php file named return that just contains
<?php
echo 'here is a string';
?>
I'm doing this through an html file containing
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
var x;
$.get("return.php", function(data){
x = data;
})
function showAlert() {alert(x);}
$(document).ready(function(){
alert(x);
});
</script>
</head>
<body>
<input type = "button" value = "Click here" onClick="showAlert();">
</body>
</html>
When the button is clicked it retrieves and displays the code fine, but on the $(document).ready thing, it displays "undefined" instead of the data in return.php. Any solutions?
Thanks.
