How to determine if a user is disconnected after a $ http request
I want to check network connectivity (online / offline) after a failed request using $ http service in AngularJs. When searching for all available response parameters in the error handler, I don't see anything that could help me.
Thanks for your help, Olivier
Code for request:
$http({ method: method, url: url, data: data, headers: headers })
.success(function (result) {
deferred.resolve(result);
})
.error(function (data, status, headers, config, statusText) {
console.log(data);
console.log(status);
console.log(headers);
console.log(config);
console.log(statusText);
deferred.reject();
});
Result in console:
GET http://192.168.0.12:3000/test net::ERR_INTERNET_DISCONNECTED ionic.bundle.js:16185
backEnd.js:25
0 backEnd.js:26
function (name) {
if (!headersObj) headersObj = parseHeaders(headers);
if (name) {
return headersObj[lowercase(name)] || null;
}
return headersObj;
} backEnd.js:27
Object {method: "GET", transformRequest: Array[1], transformResponse: Array[1], url: "http://192.168.0.12:3000/test", data: null…} backEnd.js:28
undefined backEnd.js:29

If you just want to detect whether you are online or not, you can use:
if (navigator.onLine) {
alert('online')
} else {
alert('offline');
}
For this and other online / offline verification methods check: http://www.html5rocks.com/en/mobile/workingoffthegrid/
