So'k i sorted it .....
On the PHP end i do this ...
header('Content-Type: application/json');// text/html
and on
the onSuccess i do this ...
onSuccess : function(d) {
var header=d.getHeader('Content-Type')
if(header=='application/json') {
var data=d.responseText.evalJSON();
} else { ......
This has saved me hours of work !!!!
Regards
Alex
