I have a partial HTML page in an AngularJS app that I'm trying to add a vimeo video to. This template has an image and play button that fades out on click to show the underlying iFrame. I also want this click trigger to play the video, so that someone doesn't have to press two play buttons.
The div in my partial page template where this is happening working version of site here:
<div id="container" >
<div id="dummy"></div>
<div id="element">
<iframe id="player" class="fade {{playerFade}}" ng-src="http://player.vimeo.com/video/{{person.video}}?api=1&player_id=player&wmode=opaque" frameborder="0" allowfullscreen></iframe>
<img id="person_photo" class="fade {{person_photoFade}}" ng-src="{{person.photo_small}}" ng-src-responsive="[ [ '(min-width: 720px)', '{{person.photo_medium}}' ], [ '(min-width: 960px)', '{{person.photo_large}}' ], [ '(min-width: 1200px)', '{{person.photo_extralarge}}' ] ]" />
<a id="playButton" ng-click="playing=true" class="fade {{playButtonFade}}" ><img src="img/furniture/play.png" class="img_play" alt="play button"/></a>
</div>
</div>
Now, I did get this to work once, but that was with a static, non-Angular web page. The code I used to interact with the Vimeo API is something I took from SO#8444240. They were trying to figure out preloading. Since I have so many videos, I'm not interested in that, I just used this code to get my button interacting with my video.
I tried putting this script into my index.html page, but since it is removed from Angular, it doesn't work at all. I think I need a directive. Here is the current script code I have:
<script>
//INIT Vimeo API
var vimeoPlayers = document.querySelectorAll('#player'),
player;
for (var i = 0, length = vimeoPlayers.length; i < length; i++) {
player = vimeoPlayers[i];
$f(player).addEvent('ready', ready);
}
function addEvent(element, eventName, callback) {
if (element.addEventListener) {
element.addEventListener(eventName, callback, false);
} else {
element.attachEvent(eventName, callback, false);
}
}
function ready(player_id) {
// Keep a reference to Froogaloop for this player
var container = document.getElementById(player_id).parentNode.parentNode,
froogaloop = $f(player_id);
$('#playButton a').click(function(){
$('#person_photo').fadeOut('12000');
froogaloop.api('play');
return false;
});
}
</script>
I've got a directive that controls the playbutton to fade it out (thanks to wmluke on a previous question) but I don't know how to translate this javascript into a directive. Here is my controller, too.
function DetailCtrl($scope, $routeParams, $http) {
$http.get('person.json').success(function(data) {
angular.forEach(data, function(person) {
if (person.id == $routeParams.personId)
$scope.person = person;
});
});
$scope.playing = false;
// Update the *Fade scope attributes whenever the `playing` scope attribute changes
$scope.$watch('playing', function (playing) {
$scope.playerFade = playing ? 'in' : '';
$scope.person_photoFade = playing ? '' : 'in';
$scope.playButtonFade = playing ? '' : 'in';
});
I tried writing this directive as best I could, but I don't know how to handle the ready calls to Vimeo API. It seems like there is a better way to do it in Angular.

I have a json object with images urls and I display those images with ng-repeat. My problem is that images are flickering when page is loaded for first time. I would like to display preloader (css spinner) and preload all images and than apply ng-repeat.

I have this code that loads the content when the page load,
Now I want to know how to reload the content by clicking the button.
Can you show me how to do it with example please?
Javascript code:
.controller('InterNewsCtrl', function($scope, NewsService) {
$scope.events = [];
$scope.getData = function() {
NewsService.getAll().then(function (response) {
$scope.events = response;
}), function (error) {
}
};
$scope.getData(); // load initial content.
})
Html code:
<ons-toolbar fixed-style>
<div class="left">
<ons-back-button>Voltar</ons-back-button>
</div>
<div class="right">
<ons-toolbar-button><ons-icon icon="ion-android-refresh"></ons-icon></ons-toolbar-button>
</div>
<div class="center">Internacional</div>
</ons-toolbar>
I think you're asking how to just retrieve new events from the backend. If that's correct, you don't need to reload the entire page.
You already have a function called getData which goes and retrieves you data via your service. Assuming your service doesn't cache the data, just call getData from your button:
<ons-toolbar-button ng-click="getData()"><ons-icon icon="ion-android-refresh"></ons-icon></ons-toolbar-button>
P.S. if you do explicitly have the cache set to true in your service, you can remove the cached data with $cacheFactory.get('$http').removeAll();.
For reloading same page in angular Js without post back
first remove that url from template cache if you call $route.reload() without removing it from $templateCache it will get it from cache and it will not get latest content
Try following code
$scope.getdata=function()
{
var currentPageTemplate = $route.current.templateUrl;
$templateCache.remove(currentPageTemplate);
$route.reload();
}
and Call it as following
<input type="button" ng-click="getdata();" value ="refresh"/>
Hope this will help
Please reffer this
I have three tabs(Article(s), Visitor(s), Subscription(s)) and a common place of pagination; where each tab data will be provided with pagination. On click of the respective tab; respective ng-view are coming to picture and controllers are responding properly. For this custom made pagination; i want to update the number if <li> accordingly on the basis of the server response(number of pages available for next pagination).
<div ng-app="myLibrary">
<ul>
<li>Article(s)</li>
<li>Visitor(s)</li>
<li>Subscription(s)</li>
<li>
<ul> //will behave as pagination toolbar and each <li> represents a page; after a minimum of 5 pages; i will add a combo(as in plan) to cater more page(s)
<li ng-repeat="tPageObj in recordPageNumbers">
<span ng-click="fetchPage(tPageObj.pageIndex)">{{ tPageObj.pageIndex }}</span>
</li>
</ul>
</li>
</ul>
</div>
<div ng-view></div>
When the view is rendered(after getting the data from server; i have a array with the $scope ($scope.recordPageNumbers) and calculating the page(s) accordingly. Even in the console; it shows appropriate number of page(s); but i am unable to figure-out why the ng-repeat is not behaving(as i learned so-far; being two way binding modification in the model will trigar the view update) as it should.
var myLibrary = angular.module('myLibrary', ['ngRoute', 'ngTable']);
myLibrary.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/',
{ templateUrl : 'angular-view/article.html', controller : 'articleList' } );
$routeProvider.when('/articleManager',
{ templateUrl : 'angular-view/article.html', controller : 'articleList' } );
$routeProvider.when('/visitorManager',
{ templateUrl : 'angular-view/visitor.html', controller : 'visitorList' } );
$routeProvider.when('/subscriptionsManager',
{ templateUrl : 'angular-view/subscriptions.html', controller : 'subscriptions' } );
}]);
myLibrary.controller('articleList', function($scope, $http){
$scope.articleListArray = [];
$scope.recordPageNumbers = [];
$http.get('ngMyLibrary.do?action=ALLARTICLE')
.success(function(response) {
$scope.articleListArray = response.data; //sending data to `ng-view`
var totalPageCount = response.totalPageCount;//calculating pages and according creating the `recordPageNumbers` array.
if(totalPageCount){
for(var counter = 1; counter <= totalPageCount; counter++)
$scope.recordPageNumbers.push({pageIndex : counter, disableButton : false});
} else {
$scope.recordPageNumbers.push({pageIndex : 1, disableButton : true});
}
console.log($scope.recordPageNumbers); //console show as expected
}
);
});
Console:
[Object { pageIndex=1}, Object { pageIndex=2}, Object { pageIndex=3}, Object { pageIndex=4}, Object { pageIndex=5}, Object { pageIndex=6}]
I tried with {{ $index }} as the loop index of the ng-repeat but it din't work as well. Please help. I am newbie to ng; hence could not figure out the way to check within the ng-repat tag through debug.
Without seeing the full project structure it is a bit difficult to know. But have you checked to see if the controllers scope covers the HTML you are trying to use?
For example update the first line to be
<div ng-app="myLibrary" ng-controller="articleList">
It could be that the way you have it set up with the routing, the controller is only being responsible for the HTML being injected into the ng-view part of the page.
I have layout where I have:
<li ng-click="GetLoader();">ACCOUNT</li>
<li ng-click="GetLoader();">SETTINGS</li>
On the index page, I have a menu and ng-view where I can change pages on a click
Also included on the index page is a spinner.
<div class="loading" ng-show="ticketloading" ng-init="GetLoader()">
<div>
<img class="spinner" ng-src="~/Images/ajax-loader.gif" />
</div>
</div>
In my script I have -
$scope.GetLoader = function() {
$scope.ticketloading = true;
loader.css("z-index", "1");
}
My problem is that when a user clicks on "Account" it gets loaded, but just for few milliseconds. Then it changes to all blank. I receive data from ng-view. My question is how can I delay showing ng-view to show the loader a little bit longer.
Thanx in advance!
First of all you should avoid using DOM manipulations in controller. In your case it's better to use declarative ngClass directive to set opacity.
Then your actual issue is that you don't want to use static setTimeout to hide loaded, but rather listen $routeChangeSuccess:
$rootScope.$on('$routeChangeSuccess', function() {
$rootScope.ticketloading = false;
});
and use this loading flag in template like you are currently doing.
You can put above event listener in run block for example.
You can add property in your controller, for example dataLoading and add ng-if attribute to ng-view like this:
layout
<div ng-view ng-if="!dataLoading">
controller
function loadData()
{
var self = this;
self.dataLoading = true;
dataService.loadData(params, function(){
...
self.dataLoading = false;
});
}
I am new to Angular and trying to figure out how to adapt an ASP.NET app into Angular. I need to display a different link to the user depending on the group the user belongs to. I have a Web API (ASP.NET Web API) that I can call to determine the user. I am using the following Angular code to call the Web API, but what I am unsure of is what to do next. If $scope.userGroupInfo contains the group the user belongs to how do I then display a different link in HTML depending on the group?
AngularJS
(function() {
var app = angular.module("linkSwitcher", []);
var MainController = function($scope, $http) {
var onApiCallComplete= function(response) {
$scope.userGroupInfo = response.data;
};
var onError = function(reason) {
$scope.error = "There was a problem calling the API";
};
$scope.getUserGroup = function(userId) {
$http.get("https://myapi.mysite.com/api/clients/getUserGroup/" + userId)
.then(onApiCallComplete, onError);
};
};
app.controller("MainController", MainController);
}());
HTML
<body ng-controller="MainController">
<form name="GetGroup" ng-submit="getUserGroup()">
<input type="submit" value="Lookup User Group Link" />
</form>
</body>
Please assume I have referenced the Angular library properly and that I am just displaying the portion of HTML that calls the Angular script.
well, what do you want to change in the display? you can try using ng-if="" inside a tag to show it, or you can use ng-class="someObjectMappingClassNameToBoolean" to modify the class depending on some flag.
Ex: (I don't know the structure of your response)
<div ng-if="userGroupInfo.groupId=== 7" > <a>Show me if userGroupInfo.groupId equals to 7 is true!</a> </div>
or
<div ng-class="{'blue-class': userGroupInfo.isBlue === true, 'error': userGroupInfo.isError === true }" > <a>Blue class added if isBlue is true, error class if isError is true</a></div>
You can also use ng-href to generate a calculated hyperlink, either as a whole or just as part, e.g. ng-href="http://path.to/{{groupName}}"
