I have directive named openDialog as follows. How can I use it from the view with the button click? Here is my code for the directive
app.directive('openDialog', ['ngDialog', function (ngDialog) {
return {
restrict: 'A',
link: function ($scope, $element, $attrs) {
var openDialog = function () {
ngDialog.open({
//template: $attrs.openDialog,
template: 'src/app/reservation/addReview.html',
//ngDialog.open({ template: 'src/app/reservation/addReview.html'}),
scope: $scope,
showClose: false,
closeByEscape:true
});
};
$element.on('click', openDialog);
}
};
}]);
Try like this,
<div ng-controller="ctrl">
<mydirc></mydirc>
<button ng-click="clickMe()">call clickMe()</button>
</div>
app.directive('mydirc', function() {
return {
restrict: 'E',
replace: true,
template: '<div></div>',
link: function($scope, element, attrs) {
$scope.clickMe= function() {
alert('inside click');
}
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
Your Code is right.
var app = angular.module('temp',['ngDialog']);
app.controller('mainCtrl', function($scope,$http,ngDialog){
$scope.label = "ME ANGULAR, gaga!"
});
app.directive('openDialog', ['ngDialog', function (ngDialog) {
return {
restrict: 'A',
link: function ($scope, $element, $attrs) {
var openDialog = function () {
ngDialog.open({
template: 'firstDialog',
scope: $scope,
showClose: false,
closeByEscape:true
});
};
$element.on('click', openDialog);
}
};
}]);

<script src="https://code.angularjs.org/1.6.9/angular.js"></script>
<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}}">

This is the output -
I need to pass a variable from the server side to AngularJS.
I have the following HTML on the server side
<div ng-app="tablesApp" ng-controller="tablesCtrl" ng-init="lang='#lang';...go();" ...>
<st-date-range ?lang="#lang"? ...> </st-date-range>
...
</div>
I should put somewhere in the HTML code (actually in ng-init, but if there are other options I'm OK with that) my server side #lang value, then Angular should use that value...
I use a directive and I would like to pass the #lang(a server side ASP.NET razor variable) param to angular in order to use it in the template path:
app.directive('stDateRange', [function () {
return {
restrict: 'E',
require: '^stTable',
templateUrl: '/templates/stDateRange.en.html',
scope: false,
link: function (scope, element, attr, ctrl) {
var tableState = ctrl.tableState();
scope.$watchGroup(["minDate", "maxDate"],
function (newValues, oldValues) {
so, my server side #lang param I would like to pass to the directive in order to use it in the template URL, like this:
templateUrl: '/templates/stDateRange.#(lang).html'
P.S.:
I'll take this codepen example to show my need:
var app = angular.module('app', []);
app.directive('testDirective', function(){
var lang = 'en'; // <<< Set the variable HERE << !!!
return {
restrict: 'E',
template: '<p>my lang is "<strong>'+lang+'</strong>" </p>'
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<section ng-app="app" ng-init="lang='fr'">
<h3>Test directive for 'fr' lang</h3>
<test-directive></test-directive>
</section>
If I understand you right, you want to create dynamic templateUrl based on attr.lang.
So I would write your directive as:
app.directive('stDateRange', [function () {
return {
restrict: 'E',
require: '^stTable',
template: '<ng-include src="getTemplateUrl()"/>',
scope: false,
link: function (scope, element, attr, ctrl) {
scope.getTemplateUrl = function () {
var url = '/templates/stDateRange.' + attrs.lang + '.html'
return url;
};
var tableState = ctrl.tableState();
scope.$watchGroup(["minDate", "maxDate"],
function (newValues, oldValues) {
And HTML call:
<test-directive lang="{{lang}}"></test-directive>
Demo Plunker
[Edit 1]
If you don't want to use link, you can load constant:
app.directive('testDirective', function(Constants){
var lang = Constants.val;
return {
restrict: 'E',
template: '<p>my lang is "<strong>'+lang+'</strong>" </p>'
};
});
app.constant('Constants', {
val: 'Fess'
});
Demo Codepen
You cannot use $scope on your application directive ng-app but you can use $rootScope. I would achieve this by parsing $root.language into your directive and finally load the template dynamically. You could also access $rootScope.language inside your directive directly without parsing $root.language into it. You can do as you wish - demo punkr.
AngularJS application:
var app = angular.module('plunker', []);
app.controller('ApplicationController', function($scope) {});
app.directive('test', function ($http, $compile) {
return {
scope: {
lang: '='
},
restrict: 'E',
link: function(scope, element) {
$http.get('./template.'+ scope.lang +'.html').then(function (result) {
scope.test = 'some test';
element.html(result.data);
$compile(element.contents())(scope);
});
}
};
});
View:
<!doctype html>
<html ng-app="plunker" ng-init="language = 'en'">

});
we have 2 directive list-view1 and list-view2 and also we have search directive common for everywhere.
Now my requirement is when I click search of list-view1 the data of list-view1 should be update
Similarly for list-view2.
Scenario is on click of submit I have to make api call that will return me data. after receiving data I need to update list-view with new data from where call have made.
Any Idea would be great help.
If you bind items on the html elements, the view shoud be updated automatically when the items are updated. For example,
You have a function in the controller like
$scope.search = function(){
$scope.items = getNewItems();
}
and you attached this function to the search button, if you have something like that in the view
<button ng-click="search()">Search</button>
<ul>
<li ng-repeat="item in items"> {{item}} </li>
</ul>
the items in the view will be updated when you press the search button.
I'm trying to migrate from angular 1.2.28 to angular 1.3.16, however my code broke.
Angular 1.2.28 working: http://plnkr.co/edit/XfVakwA3Upm7Z2wosHCQ?p=preview
Angular 1.3.16 not working: http://plnkr.co/edit/4VxcHL0MHddobkmu9DMG?p=preview
JS
var app = angular.module('app', []);
app.run(function($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>',
controller: function($scope, $element){
this.init = init;
function init(){
$scope.myHeight = $('.my-directive').height();

</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 trying to bind a value to a directive using '#' which is defined in the ng-init event. but this doesn't comes into my directive and it returns undefined. When does this property actually resolves is it in Compile, link? Also, why is it returning undefined always? What am I doing wrong here?
