I\'m trying to write an XMLHttpRequest using the POST method. I have managed to use XMLHttpRequest in the past using the GET method but am struggling with POST.
Here
Okay I've managed to sort it.
Odd reason though, might be sandbox security related, but rather than have the full URL address, I have just used the relative path to the file, and now it works.
Thank you all for your support.
You forgot to explicitly set to Content-type
header, which is necessary when doing POST requests.
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
Also, do not forget to use encodeURIComponent to properly encode your parameters, e.g.:
var params = "var=" + encodeURIComponent("1");
(in this particular example, it's not necessary, but when using special characters like +
things will go horribly wrong if you don't encode the parameter text).
Update – you should also replace all instances of %20
with +
, like
var params = params.replace(/%20/g, '+');
