When developing for multiple platforms, a framework might be nice. One of those frameworks is Cordova a.k.a. PhoneGap. When using jQuery Mobile, I stumbled upon the problem that I couldn’t do an ajax request to an API in Windows Phone. The same code did work for Android. After searching for a while, I found out that this problem is known and that it will not be fixed. There is, however, a workaround.

What’s happening

In Windows Phone cross-domain ajax calls are blocked.

How to solve

The bug was reported back in 2011 for jQuery. They decided not to fix it for jQuery Mobile. Instead they suggested to use $.support.cors = true;.

This does solve the problem for the calls.

Example code

$.support.cors = true;

$.ajax("http://localhost:8081/api.html", {
async: false,
contentType: "text/xml",
data: body,
type: "POST",
success: function (data, textStatus, jqXHR) {
//Handle the api call
},
error: function (jqXHR, textStatus, errorThrown) {
//Handle the error
}
});
