Run Angular Service after 1st Service has completed

Run Angular Service after 1st Service has completed - javascript

I have two Angular services. The first creates a cookie and the second sets a URL to include the created cookie. I need the first to run before the second. Normally this is not an issue when using a service as my services tend to use a http call that has a success output, but in this instance, I don't have a success call and I don't know how I can trigger that the first is complete. Here is my code as it stands:
// Set Session Cookie
appCheckCookie.getCookie();
// Get Cart URL with Session Cookie
$scope.cartURL = appCartURL.getCartURL();
I have tried wrapping these in their own functions and trying to execute them in order, but that didn't work. and I tried something like this, but it didn't work:
appCheckCookie.getCookie(function(){
$scope.cartURL = appCartURL.getCartURL();
});
Here are my two services:
appServices.factory('appCheckCookie', ['$http', function ($http) {
var getCookie = function () {
// Create session cookie
function createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else var expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
// Function to read cookie
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
var x = readCookie('ppkcookie')
if (x == null) {
// Get Session ID from backend URL
$http.post('/getSession', {}).success(function (data) {
// Create cookie from session ID from backend. Note that setting the days to 0 deletes the cookie on browser close (recommended)
createCookie('ppkcookie', data, 0);
console.log("Cookie Created: " + data);
}, function (err) {
console.log(err);
});
}
else {
var data = readCookie('ppkcookie');
console.log("Cookie Exists: " + data);
}
};
return {
getCookie: getCookie
};
}]),
appServices.factory('appCartURL', ['$http', function ($http) {
var getCartURL = function () {
// Function to read cookie
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
var x = readCookie('ppkcookie')
var baseCartURL = 'http://myecommsite.net/basket.html?Session_ID='
var cartURL = baseCartURL + x;
return cartURL;
};
return {
getCartURL: getCartURL
};
}]),

In case of handling Async operations, Promise should be one of the APIs to consider.
What is Promise?
This may give you some inspirations of how to use it in your case:
// Namespace YourService
function readCookie(name) {
return new Promise(function(resolve, reject){
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0)
resolve(c.substring(nameEQ.length, c.length));
}
resolve(null); // consider reject(null)?
});
}
// Run in service
YourService.readCookie(name).then(function(cookieResponse) {
// Run your second service after cookie retrieved
}).catch(function(reason) {
// Catch reject
});
Another thing needs to be mentioned would be IE does not support Promise natively(Of course it doesn't..), so to use it in IE, you need to apply a polyfill.
Hope this can help.

Great advice on the use of $q. Along with a colleague, this is working since we only need the 1st service to signal that it is complete:
appServices.factory('appCheckCookie', ['$q', '$http', function ($q, $http) {
var getCookie = function () {
var deferred = $q.defer();
// Create session cookie
function createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else var expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
// Function to read cookie
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
var x = readCookie('ppkcookie')
if (x == null) {
// Get GUID for the cookie
$http.post('/getSession', {}).success(function (data) {
// Create cookie. Note that setting the days to 0 deletes the cookie on browser close (recommended)
createCookie('ppkcookie', data, 0);
console.log("Cookie Created: " + data);
deferred.resolve(data);
}, function (err) {
console.log(err);
});
}
else {
var cookieExists = readCookie('ppkcookie');
console.log("Cookie Exists: " + cookieExists);
deferred.resolve(cookieExists);
}
return deferred.promise;
};
return {
getCookie: getCookie
};
}]),
Then in the controller:
appCheckCookie.getCookie().then(function (data) {
// Get Cart URL
$scope.cartURL = appCartURL.getCartURL();
console.log($scope.cartURL);
});

Javascript not letting me use 2 cookies at once that do the same thing?

I've been trying to use 2 cookies and I changed all the variables and it still won't work only one cookie will work and if I remove the code for the first cookie the second one will work and vise vira. Someone please help me get this going.
var setCookie = function (n, val) {
var exdays = 365;
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toGMTString();
document.cookie = n + "=" + val + "; " + expires;
};
var getCookie = function (n) {
var name = n + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1);
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
};
document.onclick = function (e) {
if (e.target.className == 'btn') {
var favColor = e.target.style.background;
setCookie('color', favColor);
document.getElementsByClassName('body-separator4')[0].style.background = favColor;
console.log(favColor);
}
};
window.onload = function () {
var favColor = document.getElementsByClassName("body-separator4")[0].style.background
var color = getCookie('color');
if (color === '') {
document.getElementsByClassName('body-separator4')[0].style.background = favColor;
} else {
document.getElementsByClassName('body-separator4')[0].style.background = color;
}
};
document.onclick = function (y) {
if (y.target.className == 'cbtn') {
var favbgColor = y.target.style.background;
setCookie('bgcolor', favbgColor);
document.getElementsByClassName('body-separator')[0].style.background = favbgColor;
console.log(favbgColor);
}
};
window.onload = function () {
var favbgColor = document.getElementsByClassName("body-separator")[0].style.background
var bgcolor = getCookie('bgcolor');
if (bgcolor === '') {
document.getElementsByClassName('body-separator')[0].style.background = favbgColor;
} else {
document.getElementsByClassName('body-separator')[0].style.background = bgcolor;
}
};

Good fallback for localStorage, sessionStorage and then cookie?

I'm trying to figure out the best fallback method for storing data when someone visits our site. We use this to store search filter preferences in particular, that need to move across the site as they move around. Ideally it would work with:
localStorage first
fallback to sessionStorage
then fallback to cookies
My current setup looks a bit like:
var localStorageAvail = supports_html5_storage();
var storage = "local";
if (localStorageAvail == undefined || localStorageAvail == false || localStorageAvail == null) {
storage = "cookie";
}
function supports_html5_storage() {
var testKey = 'test', storage = window.localStorage;
try {
storage.setItem(testKey, '1');
storage.removeItem(testKey);
return true;
} catch (error) {
return false;
}
}
function getValue(what) {
if (storage == "cookie") {
// get from cookie
return readCookie(what);
} else {
// localstorage
return localStorage.getItem(what)
}
}
function setValue(what,value) {
if (storage == "cookie") {
// get from cookie
writeCookie(what,value,365);
} else {
// localstorage
localStorage.setItem(what,value)
}
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function writeCookie(name,value,days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
else {
expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
}
FWIW, I'm not using jQuery, and I don't want to have to include extra libraries to do this. It needs to all be in Vanilla JS :)
My question: What is the best way to do this? Should I just tweak my current method, so it includes sessionStorage as well? Or are there better methods to do this?

How to mock cookies with QUnit and Sinon?

I have this code:
var CookieHelper = function () {
return {
GetCookie : function (cookieName) {
var cookieNameRequest = cookieName + "=";
var cookiesCollection = document.cookie.split(";");
for (var i = 0; i < cookiesCollection.length; i++) {
var cookieValuePair = cookiesCollection[i];
while (cookieValuePair.charAt(0) == " ") cookieValuePair = cookieValuePair.substring(1, cookieValuePair.length);
if (cookieValuePair.indexOf(cookieNameRequest) == 0)
return cookieValuePair.substring(cookieNameRequest.length, cookieValuePair.length);
}
return null;
},
DeleteCookie : function (cookieName) {
CookieHelper.SetCookie(cookieName, "", -1);
},
SetCookie : function (cookieName, cookieValue, cookieExpirationDays) {
var tmpDate = new Date;
if (cookieExpirationDays) {
tmpDate.setTime(tmpDate.getTime() + cookieExpirationDays * 24 * 60 * 60 * 1000);
var expires = "; expires=" + tmpDate.toGMTString();
} else {
// if cookieExpirationDays isn't set cookie will expire at the end of the day
var expirationTime = new Date(tmpDate.getFullYear(), tmpDate.getMonth(), tmpDate.getDate(), 23, 59, 59);
var expires = "; expires=" + expirationTime.toGMTString();
}
document.cookie = cookieName + "=" + cookieValue + expires + "; path=/;" + (location.protocol === "https:" ? "secure=true" : "");
}
};
}();
and I need to write unit tests for GetCookie.
I tried with:
QUnit.module('Cookie Helper Tests');
QUnit.test('GetCookie - returns no cookie', function(assert) {
var stub = sinon.spy(CookieHelper, 'GetCookie');
var cookieName = 'testCookieName';
var cookieValue = CookieHelper.GetCookie(cookieName);
assert.ok(cookieValue == null, 'returns no cookie');
});
I need to mock/stub document.cookie but I am completely new with Sinon and QUnit.
Can someone give me explanation what I did wrong?
Thanks in advance!

Well actually you can't mock properties with Sinon and more over you cannot mock the document.cookies property as it's immutable. What you can do though, is to use a fake double object that mimics the behavior of the original object, as described here.
For example, if you were running the same test outside of the browser (e.g. in NodeJS) you would do something like that
const chai = require('chai');
const sinon = require('sinon');
const SinonChai = require('sinon-chai');
chai.use(SinonChai);
chai.should();
context('test', function() {
it('should pass',
(done) => {
var cookieName = 'testCookieName';
document = {
cookie: cookieName + '=123'
};
var cookieValue = CookieHelper.GetCookie(cookieName);
console.log(cookieValue);
done();
});
});
in order to introduce a document object to the context and mimic it's cookies attribute by returning a fixed result.
Now, there is a workaround for the browser which involves redefining the getter and setter of 'document.cookie' as described here:
(function (document) {
var cookies = {};
document.__defineGetter__('cookie', function () {
var output = [];
for (var cookieName in cookies) {
output.push(cookieName + '=' + cookies[cookieName]);
}
return output.join(';');
});
document.__defineSetter__('cookie', function (s) {
var indexOfSeparator = s.indexOf('=');
var key = s.substr(0, indexOfSeparator);
var value = s.substring(indexOfSeparator + 1);
cookies[key] = value;
return key + '=' + value;
});
document.clearCookies = function () {
cookies = {};
};
})(document);

JavaScript check if a cookie exists via Name

I am trying to do a simple IF statement to check if a specific Cookie exists:
I'm not looking to over complicate anything just something simple like
if (document.cookie.name("a") == -1 {
console.log("false");
else {
console.log("true");
}
What is this syntax for this?

first:
function getCookie(name) {
var cookies = '; ' + document.cookie;
var splitCookie = cookies.split('; ' + name + '=');
if (splitCookie.lenght == 2) return splitCookie.pop();
}
then you can use your if statement:
if (getCookie('a'))
console.log("false");
else
console.log("true");
should have work.

Maybe this can help (w3schools documentation about javascript cookies) :
https://www.w3schools.com/js/js_cookies.asp
At A Function to Get a Cookie
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}

this could help you:
class Cookies {
static exists(name) {
return name && !!Cookies.get(name);
}
static set(name, value, expires = Date.now() + 8.64e+7, path = '/') {
document.cookie = `${name}=${value};expires=${expires};path=${path};`;
}
static get(name = null) {
const cookies = decodeURIComponent(document.cookie)
.split(/;\s?/)
.map(c => {
let [name, value] = c.split(/\s?=\s?/);
return {name, value};
})
;
return name
? cookies.filter(c => c.name === name).pop() || null
: cookies
;
}
}

As a WebWorks app, you are required to whitelist any external domains you will be accessing through your app. Since this works on a computer's browser but not on an actual device or on the simulator, it may be an issue with the config file. See the PhoneGap site for more info on whitelisting.
