Hi so i have these two functions which get()
is a custom ajax request function and you can see that it has two parameters url works fine but the func one which is the callback doesn't seem to change func(serverResponse); to what document.write(serverResponse);
. So I was wondering what on earth am I doing wrong? It would be great if one of the kind developers on StackOverflow could help me out really soon. Thank you so much :)
function get(url, func) {
var xhReq = new XMLHttpRequest();
xhReq.open("GET", url, false);
xhReq.send(null);
var serverResponse = xhReq.responseText;
func(serverResponse); // Shows "15"
}
get('ip.php', 'document.write');
get('ip.php', 'document.write');
should be:
get('ip.php', document.write.bind(document));
The former passes a string; the latter passes a function.
Perhaps a more typical way to do this sort of thing:
get('ip.php', function (text) {
document.write(text);
});
