I am using goldenlayout with angualrJS. I am facing below exception:
Error: ng:btstrpd App Already Bootstrapped with this Element
on execution of this line of code
myGoldenLayout.on('initialised', function () {
angular.bootstrap(angular.element('#layoutContainer')[0], ['app']);
});
The reason is, I have already ng-app in my HTML so how can I register golden layout when I already have ng-app?
https://github.com/codecapers/golden-layout-simple-angular-example/issues/1
Well, the official Golden Layout docs recommend using manual bootstrap, but if you want to keep using ng-app, then you have to make sure that your components (templates) are compiled by Angular (via $compile). Here's an example of how to do that:
angular.module('someApp') // your main module name here
.run(function ($compile, $rootScope) {
myLayout.registerComponent('template', function( container, state ){
var templateHtml = $('#' + state.templateId).html();
var compiledHtml = $compile(templateHtml)($rootScope);
container.getElement().html(compiledHtml);
});
myLayout.on( 'initialised', function() {
$rootScope.$digest(); // Golden Layout is done, let Angular know about it
});
});
// somewhere...
myLayout.init();
Basically, the main difference from the example in the repository you provided is that instead of just appending raw HTML, we $compile it with Angular, so now it knows to set up bindings and keep the html updated.
This should allow you to keep using ng-app instead of manual bootstrap.
In my app, I want to use native datepicker and tried to use this plugin, but failed to make it work. I just recently started working with Onsen UI 2 and haven't experience with using the plugins, so I might be missing something.
I followed the steps of installing and usage of the plugin. My code so far.
index.html:
<ons-list-item ng-click="ctrl.showPicker();">
Set the time
</ons-list-item>
where 'ctrl' is my controller.
index.js
this.showPicker = function() {
var options = {
date: new Date(),
mode: 'date'
};
function onSuccess(date) {
alert('Selected date: ' + date);
}
function onError(error) { // Android only
alert('Error: ' + error);
}
var datePicker = new DatePicker();
datePicker.show(options, onSuccess, onError);
}
Unfortunetely, clicking the list item shows me this error:
ReferenceError: DatePicker is not defined
As I said, I don't have experience using the plugins in Onsen UI 2, so far I was using Cordova framework (javascript and jquery). Can anyone tell me, what can I do to make the plugin work? Thanks in advance.
Your angular code looks ok. The only problem is that you don't have a DatePicker variable.
Looking at docs of the plugin which you're using it seems that it doesn't export a DatePicker function.
In the docs they are using just datePicker.show, so maybe they are just exporting datePicker.
So basically all you need to do is remove the following line:
var datePicker = new DatePicker();
And you should be fine (if you installed your plugin correctly).
I'm newbie in testing of Cordova app, so could you please give an advice about what is "best practice" in my situation?
Situation: I have a module factory:
angular
.module('app.services')
.factory('UtilsService', UtilsService);
function UtilsService() {
var service = {
isWindows: isWindows,
isAndroid: isAndroid
};
return service;
function isWindows() {
return /windows/i.test(device.platform);
}
function isAndroid() {
return /android/i.test(device.platform);
}
}
and a simple test for isWindows method:
describe('Util Service Tests', function() {
var utilSvc;
beforeEach(function() {
module('app');
});
beforeEach(function () {
inject(function($injector) {
utilSvc = $injector.get('UtilsService');
});
});
it('should detect windows', function () {
expect(utilSvc.isWindows).toBe(true);
});
});
I run tests with Chitzpah runner and get an error:
'device' is undefined
I've found the possible solution like chrome-cordova extension, but it doesn't work in my case (or I'm doing something wrong with it). So what should I do here? Mock calls to device method? If yes, how to do that?
Thanks in advance!
Have you tried using the Cordova browser platform, that can be added with the CLI:
cordova platform add browser
This provides some support for using Cordova APIs / plugins in the browser, but the plugins you're using need to support that platform usually with a JavaScript fallback to whatever their native functionality would do on an actual mobile platform such as iOS or Android. There's a good blog post covering the browser platform here. I'm not clear on how well maintained this platform is but it might be what you're looking for.
This is an ng-animate noob question. I looked at the example at angularjs.org and copied the html and css into my project. I added ngAnimate to the dependencies of my app. But it's not working. Upon (un)checking, the correct div is displayed, but no animation.
I tried adding 'ngAnimate' to the dependencies of my Controller, but then I get this error: http://errors.angularjs.org/1.2.11/$injector/unpr?p0=ngAnimateProvider%20%3C-%20ngAnimate
i notice that the example app has ng-app="ngAnimate" in the body tag, I thought adding ngAnimate to my dependencies would do the same.
Can anyone help?
here is the fiddle : enter link description here (unfortunatley angularjs not working)
var app = angular.module('my', [
'ngAnimate',
'my.controllers'
]);
var controllers = app.module('my.controllers', []);
controllers.controller('MyController', function($scope) {
$scope.checked = true;
});
upgrading from angularjs 1.2.11 to 1.3.0-beta7 did the trick.
I am developing a mobile application using Cordova and AngularJS. How do I restrict bootstrapping of AngluarJS before Cordova device ready. Basically I don't want to use any of AngularJS controllers before device ready.
Manually bootstrap your Angular app:
Remove your ng-app attribute from your HTML code, so Angular doesn't start itself.
Add something like this to you JavaScript code:
document.addEventListener("deviceready", function() {
// retrieve the DOM element that had the ng-app attribute
var domElement = document.getElementById(...) / document.querySelector(...);
angular.bootstrap(domElement, ["angularAppName"]);
}, false);
Angular documentation for bootstrapping apps.
I'm using the following solution, which allows AngularJS to be bootstrapped when running with Cordova as well as when running directly in a browser, which is where much of my development takes place. You have to remove the ng-app directive from your main index.html page since that's what the manual bootstrapping is replacing.
UPDATE: I've since switched to the following method, which I think is cleaner. It works for Ionic as well as vanilla Cordova/PhoneGap. It should be the last bit of JavaScript to run - perhaps inside a script tag before the /body tag.
angular.element(document).ready(function () {
if (window.cordova) {
console.log("Running in Cordova, will bootstrap AngularJS once 'deviceready' event fires.");
document.addEventListener('deviceready', function () {
console.log("Deviceready event has fired, bootstrapping AngularJS.");
angular.bootstrap(document.body, ['app']);
}, false);
} else {
console.log("Running in browser, bootstrapping AngularJS now.");
angular.bootstrap(document.body, ['app']);
}
});
Here's the older solution I used:
// This is a function that bootstraps AngularJS, which is called from later code
function bootstrapAngular() {
console.log("Bootstrapping AngularJS");
// This assumes your app is named "app" and is on the body tag: <body ng-app="app">
// Change the selector from "body" to whatever you need
var domElement = document.querySelector('body');
// Change the application name from "app" if needed
angular.bootstrap(domElement, ['app']);
}
// This is my preferred Cordova detection method, as it doesn't require updating.
if (document.URL.indexOf( 'http://' ) === -1
&& document.URL.indexOf( 'https://' ) === -1) {
console.log("URL: Running in Cordova/PhoneGap");
document.addEventListener("deviceready", bootstrapAngular, false);
} else {
console.log("URL: Running in browser");
bootstrapAngular();
}
If you run into problems with the http/https detection method, due to, perhaps, loading a Cordova app into the phone from the web, you could use the following method instead:
function bootstrapAngular() {
console.log("Bootstrapping AngularJS");
// This assumes your app is named "app" and is on the body tag: <body ng-app="app">
// Change the selector from "body" to whatever you need
var domElement = document.querySelector('body');
// Change the application name from "app" if needed
angular.bootstrap(domElement, ['app']);
}
// This method of user agent detection also works, though it means you might have to maintain this UA list
if (navigator.userAgent.match(/(iOS|iPhone|iPod|iPad|Android|BlackBerry)/)) {
console.log("UA: Running in Cordova/PhoneGap");
document.addEventListener("deviceready", bootstrapAngular, false);
} else {
console.log("UA: Running in browser");
bootstrapAngular();
}
Note that you still need the same bootstrapAngular function from the first example.
Why manually bootstrap AngularJS with Cordova/PhoneGap/Ionic?
Some people getting here might not know why you would want to do this in the first place. The issue is that you could have AngularJS code that relies on Cordova/PhoneGap/Ionic plugins, and those plugins won't be ready until after AngularJS has started because Cordova takes longer to get up and running on a device than the plain old Javascript code for AngularJS does.
So in those cases we have to wait until Cordova/PhoneGap/Ionic is ready before starting up (bootstrapping) AngularJS so that Angular will have everything it needs to run.
For example, say you are using the NG-Persist Angular module, which makes use of local storage for saving data on a browser, iOS Keychain plugin when running on iOS, and the cordova-plugin-file when running on Android. If your Angular app tries to load/save something right off the bat, NG-Persist's check on window.device.platform (from the device plugin) will fail because the mobile code hasn't completed startup yet, and you'll get nothing but a white page instead of your pretty app.
If you are using Ionic, this solution works for browsers and devices. Credit to romgar on this thread.
window.ionic.Platform.ready(function() {
angular.bootstrap(document, ['<your_main_app']);
});
Still need to remove ng-app from your DOM element.
This solution became more robust when I used:
angular.element(document).ready(function () {
var domElement = document.getElementById('appElement');
angular.bootstrap(domElement, ["angularAppName"]);
});
UPDATE
My suggestion was to put the above within the appropriate deviceready function, e.g.:
document.addEventListener("deviceready", function() {
angular.element(document).ready(function () {
var domElement = document.getElementById('appElement');
angular.bootstrap(domElement, ["angularAppName"]);
});
}, false);
On using the solution from TheHippo:
document.addEventListener("deviceready", function() {
// retrieve the DOM element that had the ng-app attribute
var domElement = document.getElementById(...) / document.querySelector(...);
angular.bootstrap(domElement, ["angularAppName"]);
}, false);
It doesn't work in the browser because "cordova.js" gets resolved by the Cordova or Phonegap building process and is not available in your localhost or emulated testing environment.
Thus the "deviceready" event is never fired. You can simply fire it manually in your browsers console.
var customDeviceReadyEvent = new Event('deviceready');
document.dispatchEvent(customDeviceReadyEvent);
Also make sure, that the bootstrap of angular gets triggered after setting all of you angular modules/controllers/factories/directives etc.
In most cases you probably don't need to block loading your angular app until after deviceready (mind that it can take several seconds for deviceready to fire if you have a lot of plugins).
Instead you can use something like this lib (https://github.com/arnesson/angular-cordova) which solves the deviceready issues for you by automatically buffering calls and then execute them after deviceready has been fired.
