I'm new to this please bear with me
I'm trying to achieve div toggle and button class added when button clicked (active), i looked every where i been trying to do this for over 6 hours now :(.
here is my NAV div
<div id="sidebar-wrapper-button" ng-controller="Main">
<ul class="nav nav-pills">
<li ng-click="isInfo = !isInfo" ng-class="{'active':isInfo}"></li>
<li ng-click="isSetting = !isSetting" ng-class="{'active':isSetting}"></li>
</ul>
</div>
Content Div
<div ng-class="{'ng-show':isSetting,'ng-hide':!isSetting,'ng-hide':isInfo,}">
<h1>Setting</h1>
</div>
<div ng-class="{'ng-show':isInfo,'ng-hide':!isInfo,'ng-hide':isSetting}">
<h1>Info</h1>
</div>
app.js
//toggle Setting
app.controller('Main', function($scope) {
$scope.isSetting = false;
});
//toggle Info
app.controller('Main', function($scope) {
$scope.isInfo = false;
});
Thank you.
If I understood your request right, here's what I would do:
var app = angular.module('myApp', []);
app.controller('Main', function($scope) {
$scope.tabActive = null; // here insert 1, 2 or null depending on what the initial selection should be
});
li a{text-decoration: none;}
<link href="http://getbootstrap.com/dist/css/bootstrap.min.css" rel="stylesheet"/>
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="container" ng-app="myApp">
<div ng-controller="Main">
<ul class="nav nav-pills">
<li ng-click="tabActive = 1" ng-class="{'active':tabActive == 1}">
</li>
<li ng-click="tabActive = 2" ng-class="{'active':tabActive == 2}">
</li>
</ul>
<div ng-show="tabActive == 1">
<h1>Info</h1>
</div>
<div ng-show="tabActive == 2">
<h1>Setting</h1>
</div>
</div>
</div>
Simpler way is to use angular expression {{}} to output appropriate string:
<h1>{{isSetting ? 'Setting' : 'Info'}}</h1>
Requires less markup and less class change logic code and ultimately less scope watches

Question is quite simple but i am not able to hide image. Here is the code.
I am fetching the image details from database and showing them in grid format. Here is the code.
<span class="close" id="close">×</span>
<div class="my-gallery" itemscope id="grid" >
<figure itemprop="associatedMedia" >
<a href="{{imageUrl}}" id="thumb" name="{{pid[$index]}}" class="thumbnail " itemprop="contentUrl" data-id="{{pid[$index]}}" data-size="800x600">
<img src="" class="img-responsive " data-id="{{pid[$index]}}" id="{{pid[$index]}}" ng-src="{{thumb[$index]}}" style="min-height:50px;height:50px;">
</a>
</figure>
</div>
</div>
and here are more code.
$scope.myFunc = function(btnId) {
alert(btnId);
document.getElementById(btnId).style.visibility = "visible";
};
I want to hide the respective image. there could be multiple image but image id is different. So, what i want is when user click on any image it will hide.
Please advise how can i do that.
First of all Don't use getElementById.In angular you can simple bind the $scope variable.
Have a variable with the image object to show/hide. Make it true or false when you need to show/not.
On ng-click you can set the variable to be false. bind the variable to the element, so that you can hide whenever necessary.
<div ng-if="img.show">
<img src="" class="img-responsive " data-id="{{pid[$index]}}" id="{{pid[$index]}}" ng-src="{{thumb[$index]}}" style="min-height:50px;height:50px;">
</a>
</div>
DEMO
angular.module('webapp', [])
.controller('AppCtrl', function($scope) {
$scope.data = [
{
"id": 5454554,
"Url": "https://farm4.staticflickr.com/3261/2801924702_ffbdeda927_d.jpg",
"show":true
},
{
"id": 5454554,
"Url": "https://farm4.staticflickr.com/3261/2801924702_ffbdeda927_d.jpg",
"show":true
}
];
$scope.hide = function(img){
img.show = false;
}
});
<!DOCTYPE html>
<html ng-app="webapp">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular.min.js"></script>
</head>
<body ng-controller="AppCtrl">
<div class="add-pic-box1 col-md-3">
<div ng-repeat="img in data" >
<div ng-if="img.show">
<img class="thumb" ng-model="add_new_ads_mdl.img_add" imgid = "{{img._id}}" src="{{img.Url}}" />
<button ng-click="hide(img)"> HIDE ME </button>
</div >
</div>

You can use ng-click with $event
<div ng-app="app" ng-controller="Ctrl">
Click me
</div>
app.controller("Ctrl", function($scope) {
$scope.removeMe = function(event) {
event.toElement.remove()
};
});
Example
angular 1.5
I'm creating a menu that on ng-click= i am getting the variable and than on ng-class setting that variable to true for the menu and the content.
Goal is on click to add/remove an active class to the parent and to the content div.
can't get my head around this one
<div ng-controller="myCtrl">
<ul>
<li class="animate" ng-class="{activelist: fonts ==!hidden }">
<a ng-click="activeMenu('fonts')" class="nav-icon">
menu font
</a>
</li>
<li class="animate" ng-class="{activelist: edit ==!hidden }">
<a ng-click="activeMenu('edit')" class="nav-icon">
menu edit
</a>
</li>
<ul>
<div class="">
<div class="fonttext" ng-class="{activelist: fonts ==!hidden }"></div>
<div class="edittext" ng-class="{activelist: edit ==!hidden }" ></div>
</div>
</div>
<script>
var myapp = angular.module('app', []);
myapp.controller('myCtrl', function($scope){
$scope.activeMenu = function (menuvar){
//getting the variable that gets passed via func
$scope.variable = menuvar;
// set the variable to be true no working
$scope.menuvar = true;
}
});
</script>
You can set a variable directly in ng-click to true. This variable can then be used in ng-class to dynamically add or remove classes. Here is an example:
<li class="animate" ng-class="{'activelist': fonts }">
<a ng-click="fonts = !fonts" class="nav-icon"></a>
</li>
<li class="animate" ng-class="{'activelist': edit }">
<a ng-click="edit = !edit" class="nav-icon"></a>
</li>
You can also set the variable in the controller:
HTML:
<li class="animate" ng-class="{'activelist': menu.fonts }">
<a ng-click="switchMenu('fonts')" class="nav-icon"></a>
</li>
<li class="animate" ng-class="{'activelist': menu.edit }">
<a ng-click="switchMenu('edit')" class="nav-icon"></a>
</li>
Controller:
$scope.menu = {};
$scope.switchMenu = function(selectedMenu) {
$scope.menu[selectedMenu] = !$scope.menu[selectedMenu];
};
If i am having One page with 2 tabs. and if from 2nd tab i am navigating to different page. then how to come back to that 2nd tab from navigated page? i am using $StateProvider.
Thanks.
Here is the example code and it works well,
index.html
----------------
<html>
<head>
<title>Tabs Directive</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0-rc.0/angular.min.js"></script>
<script src="tabController.js"></script>
</head>
<body>
<div class="container">
<section ng-app="myApp" ng-controller="TabController as tab">
<ul class="nav nav-pills">
<li ng-class="{active:tab.isSet(1)}"><a href ng-click="tab.setTab(1)">Tab 1</a></li>
<li ng-class="{active:tab.isSet(2)}"><a href ng-click="tab.setTab(2)">Tab 2</a></li>
<li ng-class="{active:tab.isSet(3)}"><a href ng-click="tab.setTab(3)">Tab 3</a></li>
</ul>
<div ng-show="tab.isSet(1)">
<h4>Tab 1</h4>
</div>
<div ng-show="tab.isSet(2)">
<h4>Tab 2</h4>
</div>
<div ng-show="tab.isSet(3)">
<h4>Tab 3</h4>
</div>
</section>
</div>
</body>
</html>
tabController.js
----------------
var app = angular.module('myApp', []);
app.controller('TabController', function () {
this.tab = 1;
this.setTab = function (tabId) {
this.tab = tabId;
};
this.isSet = function (tabId) {
return this.tab === tabId;
};
});
Thanks Atul :)
but this solution worked for me.
we can have one flag varibale ilke "this.isPageVisited=false" in APPCONTEXT.js file. so that variable will be available throughout the project. so suppose from tab of one page i am going to different page, what i do is i set isPageVisited=true via setter method in visted page . so now to come back to tab page again, we check the variable if its true or not. if it is true we put the "active" class to the tab element.
so that the we can have current tab active from where navigation started.
Angular.js is pretty new to me. I have learned before the $scope method for the controller and now trying the "this" method. For some reason I can not get my ng-repeat to work. here's my code:
HTML:
<ul class="nav nav-pills">
<li><a ng-click="myCtrl.tab=1" href>one</a></li>
<li><a ng-click="myCtrl.tab=2" href>two</a></li>
<li><a ng-click="myCtrl.tab=3" href>three</a></li>
</ul>
<div ng-controller="imageContr as imageCtrl">
<div ng-show="myCtrl.tab === 1" class="tab">
<h3>ONE title</h3>
<p>hello</p>
<li ng-repeat="item in gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
</div>
<div ng-show="myCtrl.tab === 2" class="tab">
<h3>TWO title</h3>
<p>how are</p>
</div>
<div ng-show="myCtrl.tab === 3" class="tab">
<h3>THREE title</h3>
<p>you?</p>
</div>
</div>
</section>
</body>
</html>
APP.JS:
(function() {
var app = angular.module('myApp', []);
app.controller('myController', function() {
this.tab = 1;
});
app.controller('imageContr', function() {
this.gallery = images;
var images = {
photo: 'image1.jpg'
};
});
})();
Declare images before you assign it, and make it an array
var images = [{ photo: 'image1.jpg' }];
this.gallery = images;
Then in your view:
<li ng-repeat="item in imageCtrl.gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
You are storing the gallery on this of the controller (which is basically the $scope), hence you need to access it in the template via imageContr as well:
<li ng-repeat="item in imageCtrl.gallery">
<img alt="imagealt" ng-src="{{item.photo}}">
</li>
You could also consider making gallery an array, so can easily iterate over it. Or you need to use the "iterate over object properties"-syntax:
<div ng-repeat="(key, value) in myObj"> ... </div>
How do I access the next()/prev() methods of the carousel from the slide? I'm trying to connect to hm-swipe-left/right, but I don't seem to have the right $scope
<carousel interval="1000">
<slide ng-repeat="card in slides" active="card.active">
<div class="card list-unstyled text-center">
<ul class='header list-inline list-unstyled'
hm-swipe-left="swipe('next')"
hm-swipe-right="swipe('prev')">
<li><i class="icon {{card.icon}} fa-3x"></i></li>
<li class="title">{{card.title}}</li>
</ul>
</div>
</slide>
</carousel>
I was looking for a solution to this. I'll post what I finally did:
In the controller where you have the carousel (make sure your html carousel has id="myCarousel"):
$scope.showNext = function(){
var index = ($('#myCarousel .active').index()+1)%(slides.length);
var modIndex = (((index)%(slides.length))+(slides.length))%(slides.length);
$scope.slides[modIndex].active=true;
}
$scope.showPrev = function(){
var index = ($('#myCarousel .active').index()-1)%(slides.length);
var modIndex = (((index)%(slides.length))+(slides.length))%(slides.length);
$scope.slides[modIndex].active=true;
}
Then in your HTML page:
<img ng-src="{{slide.image}}" style="margin:auto;" ng-swipe-right="showPrev()" ng-swipe-left="showNext()">
Hope it helps to anyone!
It works for bootstrap 3.0.2 (my version)
EDIT:
Edited the modulus (since there is a bug in javascript when calculating modulus: Javascript modulo not behaving)
Now it works! :)
In my case I was just able to do this
<div ng-swipe-left="$parent.$parent.prev()" ng-swipe-right="$parent.$parent.next()" uib-slide ng-repeat="product in vm.productList track by $index" index="$index">
I am not sure if doing $parent.$parent is advised but it worked perfectly for me and I did not have put jquery/html code in my controller.
Keep in mind I was inside a ng-repeat, it could also be $parent.next() outside of the ng-repeat.
You can get the scope of directive from DOM element and re-use it
var element = angular.element('.carousel .left');
if (element.length > 0 && element.scope && element.scope().prev) {
element.scope().prev();
}
// or
if (element.length > 0 && element.scope && element.scope().next) {
element.scope().next();
}
Here is a slightly simpler solution:
Javascript Controller
$scope.carouselNext = function() {
$('#carousel-main').carousel('next');
}
$scope.carouselPrev = function() {
$('#carousel-main').carousel('prev');
}
HTML View
<div id="carousel-main" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-main" data-slide-to="0" class="active"></li>
<li data-target="#carousel-main" data-slide-to="1"></li>
<!-- add indicators for any slides added -->
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div id="slide1" class="item active" ng-swipe-right="carouselPrev()" ng-swipe-left="carouselNext()">
<!-- img or content here -->
</div>
<div id="slide2" class="item" ng-swipe-right="carouselPrev()" ng-swipe-left="carouselNext()">
<!-- img or content here -->
</div>
<!-- add more slides as needed -->
</div>
</div>
