Javascipts:
formatter: function() {
var rV = null;
$.ajax({
dataType: "json",
url: ‘getDetail.php?tester=‘+this.series.name,
async: false, // this will stall the tooltip
success: function(data){
rV = data.tester;
}
});
return rV;
}
PHP:
<?php
header("Content-type: text/json");
$items[‘tester‘]=$tester.‘ABCDEFG‘;
print json_encode($items);
?>
