I didn't quite understand how to work with the callback for the ajax function of jQuery.
I have the following code in the JavaScript:
try {
$.ajax({
url: 'http://url.of.my.server/submit?callback=?',
cache: false,
type: 'POST',
data: $("#survey").serialize(),
dataType: "jsonp",
timeout: 200,
crossDomain: true,
jsonp: 'jsonp_callback',
success: function (data, status) {
mySurvey.closePopup();
},
error: function (xOptions, textStatus) {
mySurvey.closePopup();
}
});
} catch (err) {
mySurvey.closePopup();
}
And on the server side (AppEngine / Python) I get the value of the callback parameter and respond with
self.response.headers['Content-Type'] = 'application/json; charset=utf-8'
self.response.out.write(callback + '({"msg": "ok"});')
But then I get an "Error: jQuery152042227689944248825_1317400799214 is not a function"
in the browser console.
What is the proper way to handle this? Right now I get the results that I need, but the fact that I know it's not right is bothering me.
