Hello,
I actually had/have the same problem. It is not node.js at the backend, but
getting the f***** IE 8 to send an ajax request to a different target is a
mess, regardless of the receiver.
Your response looks good, quite similar to mine. My jQuery.ajax looks like
this:
jQuery.ajax({
url: planview_bridge_host + 'order_number',
dataType: 'json',
data: "{\"code\": \"" + id + "\", \"order_number\": \"" + order +
"\"}",
headers: {
x_auth_user: 'dirk',
x_auth_password: 'password',
x_method: 'DELETE'
},
contentType: 'application/json; charset=UTF-8',
type: 'POST',
success: function(data) {
if (data) {
setToNein();
return updateOrderNumber('undef');
} else {
return alert('Falsche Daten empfangen: ' +
JSON.stringify(data));
}
},
error: function(jqXHR, textStatus, e) {
alert(JSON.stringify(jqXHR));
setToJa();
return alert('Verbindungsproblem: ' + JSON.stringify(e));
}
});
(The JSON object is not present in IE8 by default, I added the json2.js by
Crockford to the page)
Actually I added: "jQuery.support.cors = true" in my client script. And
read somewhere that some browsers are unable to send requests with methods
other than POST and GET. So I reverted to POST everything and send the
method really meant as a custom header field ("x_method").
It works despite the fact that when a user for the first time tries to send
a request, he is asked if he truly want to send data to a different host.
Hope it helps a little.
Regards
Dirk
