angular-modal
A modal factory service for AngularJS that makes it easy to add modals to your app.
Install
npm install angular-modal
Usage
- Include the
modal.js
script provided by this component into your app. - Optional: Include the
modal.css
style provided by this component into your html. - Add
btford.modal
as a module dependency to your app.
Examples
Typical Use
app.js
angular.module('myApp', ['btford.modal']).
// let's make a modal called `myModal`
factory('myModal', function (btfModal) {
return btfModal({
controller: 'MyModalCtrl',
controllerAs: 'modal',
templateUrl: 'my-modal.html'
});
}).
// typically you'll inject the modal service into its own
// controller so that the modal can close itself
controller('MyModalCtrl', function (myModal) {
this.closeMe = myModal.deactivate;
}).
controller('MyCtrl', function (myModal) {
this.showModal = myModal.activate;
});
my-modal.html
<div class="btf-modal">
<h3>Hello {{name}}</h3>
<p><a href ng-click="modal.closeMe()">Close Me</a></p>
</div>
index.html
<div ng-app="myApp" ng-controller="MyCtrl as ctrl">
<a href ng-click="ctrl.showModal()">Show the modal</a>
</div>
Cleaning up
If you add any listeners within the modal's controller that are outside the modal's scope
,
you should remove them with $scope.$on('$destroy', fn () { ... })
to avoid creating a memory leak.
Building on the example above:
app.js
// ...
controller('MyModalCtrl', function (myModal, $timeout) {
var ctrl = this,
timeoutId;
ctrl.tickCount = 5;
ctrl.closeMe = function () {
cancelTick();
myModal.deactivate();
};
function tick() {
timeoutId = $timeout(function() {
ctrl.tickCount -= 1;
if (ctrl.tickCount <= 0) {
ctrl.closeMe();
} else {
tick();
}
}, 1000);
}
function cancelTick() {
$timeout.cancel(timeoutId);
}
$scope.$on('$destroy', cancelTick);
tick();
}).
// ...
Inline Options
Note: The best practice is to use a separate file for the template and a separate declaration for the controller, but inlining these options might be more pragmatic for cases where the template or controller is just a couple lines.
angular.module('myApp', []).
// let's make a modal called myModal
factory('myModal', function (btfModal) {
return btfModal({
controller: function () {
this.name = 'World';
},
controllerAs: 'ctrl',
template: '<div class="btf-modal">Hello {{ctrl.name}}</div>'
});
}).
controller('MyCtrl', function (myModal) {
this.showModal = myModal.activate;
});
<div ng-app="myApp" ng-controller="MyCtrl">
<a href ng-click="ctrl.showModal()">Show the modal</a>
</div>
API
btfModal
The modal factory
. Takes a configuration object as a parameter:
var modalService = btfModal({
/* options */
})
And returns a modalService
object that you can use to show/hide the modal (described below).
The config object must either have a template
or a templateUrl
option.
These options work just like the route configuration in Angular's
$routeProvider
.
config.template
string: HTML string of the template to be used for this modal.
Unless the template is very simple, you should probably use config.templateUrl
instead.
config.templateUrl
string (recommended): URL to the HTML template to be used for this modal.
config.controller
string|function (optional): The name of a controller or a controller function.
config.controllerAs
string (optional, recommended): Makes the controller available on the scope of the modal as the given name.
config.container
DOM Node (optional): DOM node to prepend . Defaults to document.body
.
modalService
A modalService
has just two methods: activate
and deactivate
.
modalService.activate
Takes a hash of objects to add to the scope of the modal as locals.
Adds the modal to the DOM by prepending it to the <body>
.
Returns a promise that resolves once the modal is active.
modalService.deactivate
Removes the modal (DOM and scope) from the DOM. Returns a promise that resolves once the modal is removed.
modalService.active
Returns whether or not the modal is currently activated.
Tests
You can run the tests with karma
:
karma start karma.conf.js
