I have a directive to display an alert message every time a post call succeeds/fails. The alert for the first post always succeeds but if I close the alert, and trigger another post the alerts don't show anymore.
Some code below:
Include tag in html
<alert message="notification"></alert>
Directive
app.directive("alert", function(){
return{
restrict: 'EA',
templateUrl: "alert.html",
replace: false,
transclude: false,
scope: {
message: "=",
close: "&"
},
link: function(){
}
};
});
Template
<div class="alert alert-{{message.type}}" ng-show="message.text">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<div>{{message.text}}</div>
</div>
UPDATE: http://plnkr.co/edit/mECmQNSgW0EdXZGPmkNx?p=preview
Any thoughts?
Thanks in advance.
Instead of using data-dismiss="alert" you can have your close button call the close function. The close function can then clear the notifications since you have $scope.notification in the isolated scope as scope.message:
var app = angular.module('app', []);
app.controller('AlertDemoCtrl', function($scope) {
$scope.notification = {};
$scope.alertNotif = function() {
$scope.notification.type = "error";
$scope.notification.text = "demo text";
};
});
app.directive("alert", function() {
return {
restrict: 'EA',
template: '<div class="alert alert-{{message.type}}" ng-show="message.text">' +
'<button type="button" class="close" ng-click="close()" aria-hidden="true">×</button>' +
'<div>{{message.text}}</div>' +
'</div>',
replace: false,
transclude: false,
scope: {
message: "=",
close: "&"
},
link: function(scope) {
scope.close = function() {
scope.message = {};
}
}
};
});

Per the Bootstrap documentation (emphasis mine):
… Closing an alert removes it from the DOM.
Because it's removed from the DOM it will not show up again...

The code is as below :

<script>
var app=angular.module("arrayApp", [])

</html>
Firstly change the name of the directive into camelCase, it's a good convention for naming directives. So your directive name should be myColor.
Then use the directive like - my-color. Below is the whole code -
<html>
<head>
<title>Directives</title>
<script src="https://code.angularjs.org/1.6.9/angular.js"></script>
<script>
var app=angular.module("arrayApp", [])
app.controller("arrayCtrl", function ($scope) {
$scope.colors = ["RED","GREEN","BLUE","YELLOW" ];
});
app.directive('myColor', function() {
return {
restrict: 'E',
transclude: 'true',
template: '<span ng-transclude></span>',
link: function(scope, element, attr){
element.append("<strong>"+attr.title+"</strong>");
}
};
});
</script>
</head>
<body ng-app="arrayApp">
<div ng-controller="arrayCtrl">
<div ng-repeat="c in colors">
<my-color title="{{c}}">
BASIC COLOR:
</my-color>
</div>
</div>
</body>
</html>
This is the output -
I just made an example of how I am trying to use transclude data binding. Well, after binding an object (message) from controller scope its "undefined" in directive's link function.
<html ng-app="myApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<script>
angular.module('myApp', []).controller('myAppController', function($scope)
{
$scope.message = { text: 'hello'}
});
angular.module('myApp').directive('myDirective', function() {
return {
restrict: 'E',
template: "<div><div ng-transclude></div></div>",
transclude: true,
scope: { message: "=" },
link: function (scope) {
// Its undefined here
console.log(scope.message);
}
};
})
</script>
</head>
<body ng-controller="myAppController">
<my-directive>
{{message.text}}
</my-directive>
</body>
</html>
Any help would be appreciated, Thanks

Sorry, maybe I have not been too clear. Actually my code is KINDA:

Im just wondering why "console.log(scope.model)" returns "undefined" in directive's link function after using scope: { model: "=" }
angular.module('myApp').directive('myDirective', function() {
return {
restrict: 'E',
template: "<div><div ng-transclude></div></div>",
transclude: true,
scope: { message: "=" },
link: function (scope) {
}
};
})
//Html
<my-directive message="message">
{{message.text}}
</my-directive>
If you are trying to pass some data to directive it's not a translusion but an isolated scope. You've almost got it. Just use your directive like this:
<body ng-controller="myAppController">
<my-directive message="message"></my-directive>
<!-- This way you're referencing your $scope.message object, so it's like you've had:
<my-directive message="{text: 'hello'}"></my-directive>
-->
</body>
Transclusion is used to pass not some data but some markup (i.e. html, other directives).
If you want to use transcluded content inside your linking function, you should use it as a 5th parameter of this function, like this:
// Directive excerpt
return {
...
transclude: true,
link: function(scope, el, attrs, ctrl, transclude) {
var transcluded = transclude();
console.log(transcluded);
}
};
// View excerpt
<my-directive message="message">
<span>{{ message.text }}</span>
</my-directive>
You can take a look at Isolating the Scope of a Directive section in angular documentation Creating Custom Directives
I'm trying to migrate from angular 1.2.28 to angular 1.3.16, however my code broke.
Angular 1.2.28 working: http://plnkr.co/edit/XfVakwA3Upm7Z2wosHCQ?p=preview
Angular 1.3.16 not working: http://plnkr.co/edit/4VxcHL0MHddobkmu9DMG?p=preview
JS
var app = angular.module('app', []);
app.run(function($rootScope, $timeout){
$rootScope.loading = true;
$timeout(function(){
$rootScope.items = ['Angular', '1.3.16', 'doesnt work'];
$rootScope.loading = false;
}, 3000);
});
app.directive('refresh', function(){
return {
restrict: 'A',
require: '^myDirective',
link: function(scope, element, attrs, ctrl){
if(scope.$last)
ctrl.init();
}
};
});
app.directive('myDirective', function(){
return {
restrict: 'E',
replace: true,
transclude: true,
template: '<div class="my-directive"><p>Height: {{myHeight}}</p> <div ng-transclude></div></div>',

<my-directive ng-hide="loading">
<div ng-repeat="item in items" refresh>
<p>{{item}}</p>
</div>
</my-directive>
</body>
</html>
The idea is to only run certain code when the inner html is outputted.
Height is 0 in angular 1.3.16.
However, if I remove ng-hide="loading" from <my-directive ng-hide="loading"> in angular 1.3.16, height gets the appropriated value.
Any ideas how can I solve this?
Inject $timeout into your directive and put the init code block in $timeout(function(){ ... }) like this:
app.directive('myDirective', function($timeout){
return {
restrict: 'E',
replace: true,
transclude: true,
template: '<div class="my-directive"><p><b>Height: {{myHeight}}</b></p> <div ng-transclude></div></div>',
controller: function($scope, $element){
this.init = init;
function init(){
$timeout(function(){
$scope.myHeight = $('.my-directive').height();
});
}
}
};
});
var app = angular.module('app', []);
app.run(function($rootScope, $timeout) {
$rootScope.loading = true;
$timeout(function() {
$rootScope.items = ['Angular', '1.3.16', ' work'];
$rootScope.loading = false;
}, 1000);
});
app.directive('myDirective', function($timeout) {
return {
restrict: 'E',
replace: true,
transclude: true,
template: '<div class="my-directive"><p>Height: {{myHeight}}</p> <div ng-transclude></div></div>',
link: function($scope, $element) {
$element.on('DOMAttrModified DOMSubtreeModified', init);
function init() {
$scope.$apply(function() {
$scope.myHeight = $element.height();
});
}
}
};
});

You have to set the height in the correct angular directive phase/lifecycle. You should set the hight in the link or even postlink phase. Usually the two phases are the same if you don't use prelink This is when all the content has already been rendered. See angular $compile or google for angular post link
The controller is for the logic and the link is for html/dom manipulations.
EDIT:
You can bind 'DOMAttrModified DOMSubtreeModified` events to trigger changes.
Hi i am working on custom directives of angularjs. I just want to know that how to call the directive when I click the button. Please suggested me how to achieve this.
Thanks
<div ng-controller="ctrl">
<mydirc></mydirc>
<button ng-click="clickMe()">call clickMe()</button>
</div>
app.directive('mydirc', function() {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function($scope, element, attrs) {
$scope.clickMe= function() {
alert('inside click');
}
}
}
});
The following example shows a sample custom directive which can handle click events; This is a scope-independent directive. And the appRoot module has to be defined earlier.
<div ng-controller="MyController">
<button custom-click="">Click Me</button>
</div>
appRoot.directive('customClick', function() {
return {
link: function(scope, element, attrs) {
element.click(function(){
//Do something useful
});
}
}
});
By "calling" the directive I am going to assume you mean handling the onclick event from the directive.
You can leverage the 'link' property of directives to attach scope initialization and functions like so:

If you mean to ask how to show a directive template on button click, use a variable in the controller scope to show/hide it and update the variable on button click.
<div ng-controller="ctrl">
<mydirc ng-show="showMydirc"></mydirc>
<button ng-click="clickMe()">call clickMe()</button>
</div>
app.controller("ctrl", function($scope){
$scope.showMydirc=false;
$scope.clickMe = function(){
$scope.showMydirc = true;
}
});
I have a modal dialog in my angularJS app, but when the user clicks on the greyed out site behind the modal, the modal closes. I want the modal to behave like a modal, ie, you have to respond to what's inside in order to get it to close. Can anyone tell me how to achieve this? Here is a jsbin:

Assuming you're using Bootstrap set the backdrop to static.
var modalInstance = $modal.open({
templateUrl: '/App/Documents/Templates/DeleteDocumentDialogTemplate.html',
backdrop: 'static'
});
In this section of your directive's template, remove ng-click='hideModal()' and you're done.
<div class='ng-modal-overlay' ng-click='hideModal()'>
