I need to show link in page having attribute value mailto.
normal href attribute value working fine but if value is email than it removed
Code:
myCtrl.link = '<code>Email</code>';
<code><span ng-bind-html="myCtrl.link"></span></code>
rendered output:
<code><a target="_blank">Email</a></code>
Please suggest how to handle anchor having href value like mailto:sulok#atlogys.com
You are running into a "security" issue,
please have a look at this doc-page...
Just say "this is safe" to angular:
function TestCtrl(vm, $sce) {
'use strict';
var htmlString = '<code>Email</code>';
vm.link = $sce.trustAsHtml(htmlString);
}
angular
.module('test', [])
.controller('TestCtrl', ['$scope', '$sce', TestCtrl])
;
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<article ng-app="test">
<div ng-controller="TestCtrl">
<code><span ng-bind="link"></span></code>
</div>

basically i want to change the attribute value based on the button i clicked,
these are the two buttons
<button ng-click="fn(a)"></button>
<button ng-click="fn(b)"></button>
and then i have a prebuilt directive who takes value as input,
<div directive-name="" id="abc"></div>
if i click on first button,i want the value of directive based on button clicked.
What i did earlier;
$scope.go = function(data){
if(data==a){
var b = document.querySelector( 'div' );
b.setAttribute("directive-name","value");
}
else{}
}
here the problem is that it is selecting the first div of document and setting attribute value for that.
I also tried to pass it with id like
var b = angular.element(document.querySelector('#abc'));
I also saw some custom directives to do so, but they are not working
AngularJS DOM Manipulation through Directives
If possible provide me a demo in plunkr or fiddle
and also if i want to change css property of div based on button clicked
Thanks in advance
You can do it like this.
Assign the directive-name value to a $scope.variable and then use variable as the value in HTML.
HTML - 1:
<button ng-click="go(a)"></button>
<button ng-click="go(b)"></button>
HTML - 2:
<div directive-name="{{directive}}" id="abc"></div>
JS:
$scope.go = function(data){
if(data==a){
$scope.directive = "directive-1";
}else if(data==b){
$scope.directive = "directive-2";
}
}
To assign class name to div you can define other $scope.classVar and then use that in HTML like below:
<div directive-name="{{directive}}" id="abc" ng-class="classVar"></div>
I hope this will solve your problem.
This should work, (you had some errors in your code):-
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.fn = function(data,id) {
if (data == 'a') {
var b = document.querySelector('#'+id);
b.setAttribute("directive-name", "value");
} else {
}
}
});

<div ng-app="myApp" ng-controller="myCtrl">
<div directive-name="" id="abc"></div>
<button ng-click="fn('a','abc')">A</button>
</div>
"Basically I want to change the attribute value based on the button I clicked."
You can do this by changing the attribute value the angular way, referencing a property of $scope or the controller instance in your template. When clicking a button, set the variable to the value you require to be passed to your directive.
Note: When you pass a value into your ngClick directive, you need to pass it as a string unless a and b are declared as properties of $scope.
Here's a basic example:
// app.js
(function() {
'use strict';
angular.module('app', []);
})();
// main.controller.js
(function() {
'use strict';
angular.module('app').controller('MainController', MainController);
MainController.$inject = ['$scope'];
function MainController($scope) {
$scope.fn = fn;
function fn(data) {
// set the value so it's accessable in the view
// therefore we can pass it into our directive
$scope.myVar = data;
}
}
})();
// directive-name.directive.js
(function() {
'use strict';
angular.module('app').directive('directiveName', directiveNameDirective);
function directiveNameDirective() {
return {
restrict: 'A',
scope: {
directiveName: '='
},
template: '<span>directiveName: {{ directiveName }}</span>'
};
}
})();
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
<div ng-app="app">
<div ng-controller="MainController as MainCtrl">
<!-- here we pass a and b as strings otherwise they get evaluated as variables -->
<button ng-click="fn('a')">Set a</button>
<button ng-click="fn('b')">Set b</button>
<hr>
<!-- here we pass myVar which is declared as a property of $scope when the fn function is called -->
<div directive-name="myVar" id="abc"></div>
<hr> myVar: {{ myVar }}
</div>
</div>
In my MVC program simple angular value controllers values are not binding.
My code is as follows :
_Layout.cshtml
<body data-ng-app="ShoppingCartApp">
<div class="container body-content">
#RenderBody()
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/Scripts/angular.js")
#Scripts.Render("~/Scripts/Custom/App.js")
#Scripts.Render("~/Scripts/Custom/ShoppingCartController.js")
#RenderSection("scripts", required: false)
<hr />
</div>
</body>
App.js
var app = angular.module('ShoppingCartApp', []);
ShoppingCartController.js
app.controller('ShoppingCartController', function ShoppingCartController($scope, $http) {
$scope.ShoppingCartObj.products = [];
$scope.test = "ABC";
// On load events
// $scope.loadValues();
});
My Html Code is follows :
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<script></script>
<h2>Index</h2>
Total {{2+2}} // This value workd FINE
<div ng-controller="ShoppingCartController">
<div class="row">
<div class="nav navbar-nav navbar-left">
<h3>Total {{2+2}}</h3> // Not working THIS
</div>
<h1>{{test}}</h1> // Not working THIS
</div>
</div>
When i try to access value in controller or access directive inside controller it's not working. What i miss in here?
Change your controller to:
app.controller('ShoppingCartController', function($scope, $http) {....});
Or create a function named ShoppingCartController and then pass it to controller:
app.controller('ShoppingCartController', ShoppingCartController);
Also change $scope.ShoppingCartObj.products to $scope.ShoppingCartObj = {}; and then add products to that object $scope.ShoppingCartObj.products = []; because, prev you havnt defined what $scope.ShoppingCartObj is, so this object will be undefined.
If you're using Bundler you need to specify the Dependency Injection values
Also - ShoppingCartObj isn't declared anywhere so you can't assign to a property products
app.controller('ShoppingCartController', ['$scope', '$http',
function ShoppingCartController($scope, $http) {
$scope.ShoppingCartObj = {},
$scope.ShoppingCartObj.products = [];
$scope.test = "ABC";
}]);
Here's a working Jsfiddle
I'm trying to get the component method working which is new for Angular 1.5. So far I acheived the following see my jsFiddle JSFIDDLE. For some reason I can not get the templateUrl working so that I can see the html template with the defined scope. Any help would be great.
JSFIDDLE
JS
var app = angular.module('myApp', []);
app.controller('mainCtrl', function($scope) {
$scope.name = "Tony Danza";
});
app.component("myBox", {
bindings: {},
controller: function($element) {
var myBox = this;
myBox.game = 'World Of warcraft';
},
controllerAs: 'myBox',
templateUrl: "/template",
transclude: true
})
HTML
<div ng-app="myApp" ng-controller="mainCtrl">
<script type="text/ng-template" id="/template">
<div style='width:40%;border:2px solid black;background-color:yellow'>
Your Favourite game is: {{myBox.game}}
</div>
</script>
Hi {{name}}
<div my-box>
</div my-box>
</div><!--end app-->
Angular components must be elements. Use <my-box> instead of <div my-box>.
The documentation on Components doesn't make this immediately clear, but it is documented.
when you want a directive that is triggered by an attribute or CSS class, rather than an element
The directive/component comparison table also explains that restrict is unavailable for components and they are always elements.
Here when i click on cartDetails the dynamic scope variable x.SmId value need to be passed to the bellow function and in alert box need to display the parameter .How can we do this one in angular js?
<div ng-app="" ng-controller="MyCtrl">
<div ng-repeat="x in names">
<div ng-click="cartDetails('{{x.SmId}}')">
<div>{{x.name}}</div>
</div>
</div>
</div>
<script>
angular.module('MyApp', [])
.controller('MyCtrl', ['$scope', '$http', function($scope, $http) {
$scope.search = function(param) {
$http.get('AngularJs-Response.jsp?mid='+param).success(function(response) {
$scope.names = response;
});
};
$scope.cartDetails = function(smid) {
alert(smid);
};
}]);
</script>
Use simple:-
ng-click="cartDetails(x.SmId)"
I tried to use:
ng-click="cartDetails(x.SmId)"
but it simply x.SmId as string, its not replaced by value. After reading few more articles, I found a solution like below:
<div ng-click="cartDetails('{{x.SmId}}')">
Its a working solution in AngularJS v1.3.9
Suppose you are using routes:
// bootstrap
myApp.config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {
$routeProvider.when('/home', {
templateUrl: 'partials/home.html',
controller: 'HomeCtrl'
});
$routeProvider.when('/about', {
templateUrl: 'partials/about.html',
controller: 'AboutCtrl'
});
...
And in your html, you want to navigate to the about page when a button is clicked. One way would be
<a href="#/about">
... but it seems ng-click would be useful here too.
Is that assumption correct? That ng-click be used instead of anchor?
If so, how would that work? IE:
<div ng-click="/about">
Routes monitor the $location service and respond to changes in URL (typically through the hash). To "activate" a route, you simply change the URL. The easiest way to do that is with anchor tags.
Go Home
Go to About
Nothing more complicated is needed. If, however, you must do this from code, the proper way is by using the $location service:
$scope.go = function ( path ) {
$location.path( path );
};
Which, for example, a button could trigger:
<button ng-click="go('/home')"></button>
Here's a great tip that nobody mentioned. In the controller that the function is within, you need to include the location provider:
app.controller('SlideController', ['$scope', '$location',function($scope, $location){
$scope.goNext = function (hash) {
$location.path(hash);
}
;]);
<!--the code to call it from within the partial:---> <div ng-click='goNext("/page2")'>next page</div>
Using a custom attribute (implemented with a directive) is perhaps the cleanest way. Here's my version, based on #Josh and #sean's suggestions.
angular.module('mymodule', [])
// Click to navigate
// similar to <a href="#/partial"> but hash is not required,
// e.g. <div click-link="/partial">
.directive('clickLink', ['$location', function($location) {
return {
link: function(scope, element, attrs) {
element.on('click', function() {
scope.$apply(function() {
$location.path(attrs.clickLink);
});
});
}
}
}]);
It has some useful features, but I'm new to Angular so there's probably room for improvement.
Remember that if you use ng-click for routing you will not be able to right-click the element and choose 'open in new tab' or ctrl clicking the link. I try to use ng-href when in comes to navigation. ng-click is better to use on buttons for operations or visual effects like collapse.
But
About
I would not recommend. If you change the route you might need to change in a lot of placed in the application. Have a method returning the link. ex:
About. This method you place in a utility
I used ng-click directive to call a function, while requesting route templateUrl, to decide which <div> has to be show or hide inside route templateUrl page or for different scenarios.
AngularJS 1.6.9
Lets see an example, when in routing page, I need either the add <div> or the edit <div>, which I control using the parent controller models $scope.addProduct and $scope.editProduct boolean.

both pages -
RoutingTesting.html(parent), TestingPage.html(routing page) are in the same directory,
Hope this will help someone.
Another solution but without using ng-click which still works even for other tags than <a>:
<tr [routerLink]="['/about']">
This way you can also pass parameters to your route: https://stackoverflow.com/a/40045556/838494
(This is my first day with angular. Gentle feedback is welcome)
You can use:
<a ng-href="#/about">About</a>
If you want some dynamic variable inside href you can do like this way:
<a ng-href="{{link + 123}}">Link to 123</a>
Where link is Angular scope variable.
just do it as follows
in your html write:
<button ng-click="going()">goto</button>
And in your controller, add $state as follows:
.controller('homeCTRL', function($scope, **$state**) {
$scope.going = function(){
$state.go('your route');
}
})
