I am running an AngularJS application/controller. My goal is to initialize and use the impress.js library on a page that is being dynamically loaded into my main home page. However, when I try to initialize the library, the page does not load. Attached is a snippet of the controller and html file.
NOTE: When I print the impress() object to the console, it is not null, and has the required functions. It is my suspicion that the impress() object is not hooking up to the page correctly.
Controller:
'use strict';
// Create the angular module
var cmodule = angular.module('coverage', ['ngRoute'])
// Create the coverage controller
cmodule.controller('coverageController', function($scope) {
console.log("Entering controller");
function require(script) {
$.ajax({
url: script,
dataType: "script",
async: true, // <-- This is the key
success: function () {
console.log(impress());
impress().init();
},
error: function () {
throw new Error("Could not load script " + script);
}
});
}
console.log("About to require");
angular.element(document).ready(function () {
require("/content/libraries/impress.js");
});
});

This problem was fixed by using the jmpress.js library instead, found here.

Problem: I have created a webpage with an md-card that has a button. Upon clicking that button, I want another card to appear. The Problem: I cannot figure out, how to make the button of the new card work. It is not correctly formated and it has no functionality.
Question: What do I need to change the code to, to make it work? Thanks.
Code: This is my JavaScript-Code:
angular.module('MyApp', ['ngMaterial', 'ngMessages', 'material.svgAssetsCache'])
.controller('AppCtrl', function($scope, $mdDialog) {
function addMeinElement () {
// create a new div element
var newDiv = document.createElement("md-card");
document.querySelector('#myID').appendChild(newDiv);
newDiv.innerHTML = "<md-card-content>Oh no! Why does this button not work?<br>"+
"<md-button class='md-warn' ng-click='my_print_to_console()'>Button :( </md-button>"+
"</md-card-content>";
}
$scope.my_print_to_console = function () {
addMeinElement ();
};
});
This is the corresponding html:

It happens because Angular not aware that this is a an Angular component. you need to wrap your HTML with $compile service.
Add '$compile' to your module dependency
Wrap the code like that
$compile('your html here')($scope);
I cant get this simple angular app to work. I know I am probably doing something silly. If anyone can help I would greatly appreciate it.When I run it I'm getting the following error:
0x800a139e - JavaScript runtime error: [ng:areq] Argument 'timesheetListCtrl' is not a function, got undefined

var timesheetManagement = angular

}());
timesheetListCtrl.js
(function () {
"use strict";
angular
.module("timesheetManagement")
.controller("timesheetListCtrl",
["timesheetResource", timesheetListCtrl]);
function timesheetListCtrl(timesheetResource) {
var vm = this;
timesheetResource.query(function (data) {
vm.timesheets = data
});
}
}());
So, it turns out you have to include timesheetListCtrl.js in index.html
Hello i'm building an application where i want to dynamically change the source of an image in order to force reload it . The problem is that in order of this i only get a broken image on the browser. Instead , if a run the function manually by a button it runs perfect .

function updateImage() {

console.log('Snapshot Loaded');
$scope.snapshot = img;

$scope.readSnapshot = updateImage;
$scope.getSnapshot = function() {
$http.get('/api/getSnapshot')
.then(function(response) {
// this callback will be called asynchronously

console.log('Snapshot captured');

$scope.intervalFunction = function() {
$timeout(function() {

};
// Kick off the interval
$scope.intervalFunction();
});
There are two solutions I've used for this in the past.
1) Use an ng-if/ng-show on your img tag. This will prevent the broken image from displaying.
<img ng-if='snapshot'>
2) Set a default image that will load and then be replaced once the other images load.
$scope.snapshot = 'snapshots/default.png';
I am a newb with angularjs and I am trying something that I believe should be very simple ... but turns out I am not figuring it out.
I have a $scope variable that I want to double bind (using ng-model) to a textarea. I was able to make it work on js fiddle websites but now on my code. I have tried to strip everything down to just a few lines and it still doesn't work, the controller is never updated.
this is my code:
js/main.js
var app=angular
.module('noclu', ['ionic', 'app.controllers'])
.config(function ($stateProvider, $urlRouterProvider){
$stateProvider
.state('menu.main', {
url: "/main",
views: {
'menuContent': {
templateUrl: 'templates/main.html',
controller: 'MainCtrl'
}
}
});
$urlRouterProvider.otherwise("/menu/main");
});
js/controller.js
angular
.module('app.controllers', [])
.controller('MainCtrl', function ($scope){
$scope.src='---';
$scope.get_feeds=function(){
//seems like that here "this" is actually the textarea ??
//$scope.src is always whatever has been set in the controller
console.log('this:'+this.src); //this output whatever I enter in the textarea
console.log('scope:'+$scope.src); //this always output '---'
};
});

UPDATE - I made it work, but why ?
I made it work by changing $scope.src='---'; to $scope.src={body:'---'}; and then changing the ng-modal to src.body. but.. WHY did not work the other way as it works for boolean?
Using directly $scope. is not a good practice in angularJS. There are various post of it, more concernign $scope inheritence.
For exemple : http://learnwebtutorials.com/why-ng-model-value-should-contain-a-dot
Therefore, your need to change your model like that :
$scope.myModel = {};
$scope.myModel.src = "---"
And your html to bind to myModel.src
I am learning to use Restify to build a Restful API and work with Angular.
Below is my structure:
Project
page_admin
core.js
index.html
node_modules
restify
mongojs
server.js
I had set up server and implemented several API calls.
Below news API return a list of JSON data in browser:
`http://localhost:8080/news`
`[{"_id":"53b2a2c3373551813dfe8b91","title":"first","subtitle":"foobar","textbody":"","postedOn":"2014-07-01T12:00:03.215Z"},{"_id":"53b2a122373551813dfe8b8e","title":"my second","subtitle":"my second title","textbody":"node is cool","postedOn":"2014-07-01T11:53:06.389Z"},{"_id":"53b2a0cd373551813dfe8b8d","title":"delay announcement","subtitle":"sub ","textbody":"I am the text body","postedOn":"2014-07-01T11:51:41.678Z"}]`
here is my code to handle client side route:
server.get('/', restify.serveStatic({
'directory': './page_admin',
'default': 'index.html'
}));
My index.html is simple:
<!-- index.html -->
<!doctype html>
<!-- ASSIGN OUR ANGULAR MODULE -->

core.js is like this:
var bluesky = angular.module('bluesky', []);
function mainController($scope, $http) {
$scope.formData = {};
$http.get('/news')
.success(function(data) {
$scope.news = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
}
when I try to navigate to: http://localhost:8080
I got my index page but it shows me:
'My example is working {{ news.length }}
and in console, I saw following error:
GET `http://localhost:8080/core.js` 404 (Not Found)
localhost/:24
Uncaught Error: No module: bluesky
angular.min.js:18
what I just missed so that the angular is not retrieving the data?
=============================================================
upate
if I directly include core.js put code inside , then it works.
but, how to solve this 404 not found issue? just don't want to include all js files in the index page.
As far as my knowledge about angular js, controller is not defined in your module. So instead of using function mainController($scope, $http) {
....
}
you should define controller inside the module bluesky as follows
bluesky.controller("mainController",function($scope,$http)
{
....
});
