I want to write a script in Ionic to refresh a page every 5 minutes or to call the API every 5 minutes. I have tried to use the $interval function but it didn't work. Can anyone give me ideas on where to and how to start ?
Try this
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script type="text/javascript">
angular.module('myModule', [])
.controller('myCtrl', function ($interval, $window) {
$interval(function () {
// loading page again
// $window.location.reload();
//you can modify it as you needd
console.log('called in 5 seconds for 5 minutes change 5000 to 1000*60*5');
}, 5000);
});
</script>
<body ng-app="myModule" ng-controller="myCtrl">
</body>
</html>
Edited
$interval(function () {
// loading page again
// $window.location.reload();
//you can modify it as you needd
$scope.timer = $scope.timer + 5000;
console.log('called in 5 seconds for 5 minutes change 5000 to 1000*60*5');
}, $scope.timer);
this is what you need:
angular.module('test', [])
.controller('test', function ($interval, $timeout, $window) {
//$timeout( function () {
$interval(function () {
// Refresh page
$window.location.reload();
// Or call api
//$http({
//})
}, 1000*60*5);
//}, 1000);
});

<div ng-app="test" ng-controller="test">

In the below code, console.log($scope.gradeC.title); shows the correct output; however the next console line does not show the expected output. I do not understand this behaviour. Any suggestions/pointers would help me to understand this.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script>
var myApp=angular.module("myApp", []);
myApp.controller('myCtrl', function($scope, $filter)
{
console.log("Inside controller");
$scope.results = {
year:2013,
subjects:[
{title:'English',grade:'A'},
{title:'Maths',grade:'A'},
{title:'Science',grade:'B'},
{title:'Geography',grade:'C'}
]
};
console.log($scope.results);
$scope.gradeC = $filter('filter')($scope.results.subjects, {grade: 'B'})[0];
console.log($scope.gradeC.title);
console.log(($scope.results.subjects|{grade: 'B'})[0].title);
});
</script>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<h4>Printing div</h4>
</body>
</html>
you can't use | in controller to filter arrays.
$scope.gradeC = $filter('filter')($scope.results.subjects, {grade: 'C'})[0];
console.log($scope.gradeC);
or
console.log($filter('filter')($scope.results.subjects, {grade: 'C'})[0].title);
I am calling restful service from AngularJS. HTML is very basic with a input text box and a button for query.
// basic.html
<!DOCTYPE html>
<html ng-app="cgApp" >
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-resource.js"></script>
<script src="../js/controller.js"></script>
<script src="../js/service.js"></script>
</head>
<body>
<div ng-controller="CgseqCtrl">
<input ng-model="analysisid"><button ng-click="searchById()">Search</button>
<table>
<tr>
<td>{{seq.analysisId}}</td>
<td>{{seq.center}}</td>
<td>{{seq.diseaseAbbr}}</td>
<td>{{seq.filepath}}</td>
<td>{{seq.library}}</td>
</tr>
</table>
</div>
</body>
</html>
I use a service to call rest api
// service.js
app.factory("Cgseq", function ($http) {
// return $resource('http://localhost:8080/cgweb/api/seqs/fdebfd6e-d046-4192-8b97-ac9f65dc2009');
var service = {};
service.getSeqById = function(analysisid) {
return http.get('http://localhost:8080/cgweb/api/seqs/' + analysisid);
}
service.getSeq = function() {
return $http.get('http://localhost:8080/cgweb/api/seqs/fdebfd6e-d046-4192-8b97-ac9f65dc2009');
}
return service;
});
The function searchById() will be executed once the button is clicked. It is implemented in my controller.
// controller.js
var app = angular.module('cgApp', [])
app.controller('CgseqCtrl', ['$scope', 'Cgseq', function($scope, Cgseq){
$scope.searchById() = function() {
CgSeq.getSeqById($scope.analysisid)
.then(function(response){
$scope.seq = response;
});
}
}]);
When I load basic.html in a browser, even before I type in something in the input box and click the button, I got the following error:
angular.js:12416 TypeError: $scope.searchById is not a function
at new <anonymous> (controller.js:8)
You should remove the () from $scope.searchById() = function
And correct the typo (case-sensitivity) for Cgseq
I.e.:
$scope.searchById = function() {
Cgseq.getSeqById($scope.analysisid)
.then(function(response){
$scope.seq = response;
});
}
I want to create following event(s) using angularjs.
mousemove
keydown
DOMMouseScroll
mousewheel
mousedown
touchstart
touchmove
scroll
Now what I am trying is as following...,
<!DOCTYPE html>
<html ng-app="appname">
<head>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.20/angular.min.js"></script>
</head>
<body>
</body>
<script>
var app = angular.module('appname', []);
app.directive('myDirective', function() {
alert("Hello");
return {
link: function(scope, element) {
scope.appname.$on('mousemove', function() {
alert("mousemove");
});
scope.appname.$on('keydown', function() {
alert("keydown");
});
scope.appname.$on('DOMMouseScroll', function() {
alert("DOMMouseScroll");
});
});
}
});
</script>
</html>
But I cannot get it working. Let me get your suggestions.
Since each $scope inherits from the $rootScope and you are not using an isolated scope here, you can use $rootScope.$on to subscribe to the events for your whole application.
A great introduction can be found here.
After,I learned from this answer, I got it working in following code.
<!DOCTYPE html>
<html ng-app="testApp">
<head>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.20/angular.min.js"></script>
</head>
<body>
</body>
<script>
var app = angular.module('testApp', []);
app.run(['$document', function($document) {
var bodyElement = angular.element($document);
bodyElement.bind('click', function (e) {
console.log('click');
});
bodyElement.bind('mousemove', function (e) {
console.log('mousemove');
});
bodyElement.bind('keydown', function (e) {
console.log('keydown');
});
bodyElement.bind('DOMMouseScroll', function (e) {
console.log('DOMMouseScroll');
});
bodyElement.bind('mousewheel', function (e) {
console.log('mousewheel');
});
bodyElement.bind('mousedown', function (e) {
console.log('mousedown');
});
bodyElement.bind('touchstart', function (e) {
console.log('touchstart');
});
bodyElement.bind('touchmove', function (e) {
console.log('touchmove');
});
bodyElement.bind('scroll', function (e) {
console.log('scroll');
});
}]);
</script>

So i've split out my UI into subcomponents but then i realise that one of the components requires to be react to a dropdown change which is caught by the parent controller.
I can create a shared service for the variables and i have been able to inject the sub controller so that i can kick off functions BUT.
how do i then use the scope within the sub controller?
var ctrl1= $scope.$new();
$controller('ctrl', { $scope: ctrl1});
ctrl1.GetData();
this works fine. I can see data coming back in the console. BUT my ui doesnt change. What am i missing?
I've edited the post to illustrate what i'm attempting to do more clearly.
The drop down on change is caught by the parent controller but i then require the child controller to run away and get some data and update the UI.
It's an attempt to split out the components. Is this possible? Or have a split the components out too far?

<script>
angular.module('app2', [])
.controller('ctrl2', ['$scope', '$http', function($scope, $http){
$scope.getdata = function(){
$http.post(WebServiceURL)
.success(function(data){
$scope.app2Data = "test2 data";
});
}
}]);
angular.module('app1', ['app2'])
.controller('ctrl1', ['$scope','$controller',function($scope, $controller){
$scope.name = 'Controller 1';
//just something to put in the ddp
$scope.data = [
{id:1, name: "test"},
{id:2, name: "test2"}
]
$scope.makeChanged = function(id){
//ddp has changed so i refresh the ui with some other data which is in got by ctrl2.
var cl2 = $scope.$new();
$controller('ctrl2', { $scope: cl2 });
cl2.getdata();
}
}]);
</script>
</head>
<body ng-app="app1">
<div ng-controller="ctrl1">
<p>here is: {{name}}</p>
<select ng-model="d" ng-options="d as dat.name for dat in data track by dat.id" ng-change="makeChanged(d.id)"></select>
<div>
{{app2Data.text}}
</div>
</div>
</body>
</html>
for anyone interested here's how i got round this.
I created a shared service between the two controllers. and created a callback on the service. i registered the call back on ctrl2 so when the shared variable changed the controller2 will do what i want it to and scope is freshed.

//just something to put in the ddp
$scope.data = [{
id: 1,
name: 'test'
}, {
id: 2,
name: 'test2'
}];
$scope.makeChanged = function(value) {
//ddp has changed so i refresh the ui with some other data which is in got by ctrl2.
appointmentSharedProperties.setDetail(value);
console.log('in makeChanged: ' + value);
}
}
]).service('appointmentSharedProperties', function() {
var test = '';
var __callback = [];
return {
getDetail: function() {
return test;
},
setDetail: function(value) {
test = value;
if (__callback.length > 0) {
angular.forEach(__callback, function(callback) {
callback();
});
}

setCallback: function(callback) {
__callback.push(callback);
}
};
});
angular.module('app2', [])

function($scope, appointmentSharedProperties) {
$scope.name2 = 'Controller 2';
console.log('ctrl2');
var getdata = function() {
console.log('in getdata');
$scope.app2Data = appointmentSharedProperties.getDetail();

appointmentSharedProperties.setCallback(getdata);

General example of how to pass variables from one controller to other
<html>
<head>
<meta charset="ISO-8859-1">

This is the javascript file for this
var myApp = angular.module('myApp',[]);
myApp.service('sampleService', function(){
var temp = '';
this.setValue = function(data){
temp = data;
}
this.getValue = function(){
return temp;

myApp.controller('ctrl1', function($scope,sampleService) {
$scope.greeting = 'This line is in first controller but I exist in both';
var data= $scope.greeting;
sampleService.setValue(data);
});
myApp.controller('ctrl2', function($scope, sampleService){
$scope.dataToHtml2 =sampleService.getValue();
});

It has the demo of what I written. Happy coding..!!
I believe I have set everything for Angular to work in Phonegap, but apparently the deviceready function is not having the behavior that I expect.
So here is how I set:
index.html
<html ng-app="app">
<head>
<script type="text/javascript" src="js/lib/angular.min.js"></script>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/lib/ready.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</head>
<body>
<div class="header" ng-controller="HeaderController">
<h3 id="logo"><img src="img/logo.png"/></h3>
<p>{{title}}</p>
<button ng-click="changeTitle()"></button>
</div>
</body>
</html>
app.js
$app = angular.module('app', ['fsCordova']);
$app.config(function($compileProvider){
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel):/);
});
$app.controller('HeaderController', function($scope, CordovaService) {
CordovaService.ready.then(function() {
console.log("Setting the title");
$scope.title = "This title";
$scope.changeTitle = function() {
console.log("Changing the title");
$scope.title = "Title changed";
}
});
});
ready.js from: http://www.ng-newsletter.com/posts/angular-on-mobile.html#native
angular.module('fsCordova', [])
.service('CordovaService', ['$document', '$q',
function($document, $q) {
var d = $q.defer(),
resolved = false;
var self = this;
this.ready = d.promise;
document.addEventListener('deviceready', function() {
resolved = true;
d.resolve(window.cordova);
});
// Check to make sure we didn't miss the
// event (just in case)
setTimeout(function() {
if (!resolved) {
if (window.cordova) d.resolve(window.cordova);
}
}, 3000);
}]);
The title is appearing the way it is {{title}}, not its value. When I click the button, nothing happens, not even the debug logs on the console. Any tips how to set Angular on Phonegap? Thanks.
Apparently on angular 1.2 the urlSanitizationWhitelist doesn't exist anymore.
So I just had to remove the $compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel):/); line and it worked
