JunIn Angular, templates are the views with the HTML enriched by Angular elements like directive and attributes. Templates are used to display the information from the model and controller that a user sees in his browser. An angular templates can have Directive, HTML markup, CSS, Filters, Expressions and Form controls.
A simple Angular Template
<html ng-app> <body ng-controller="MyController"> <input ng-model="name" value="dotnet-tricks.com"> <br/> Input Value is : {{name}} <button ng-click="changeValue()">Click me!</button> <script src="angular.js"> </body> </html>
Types of Templates
There are two types of templates :
Static Templates
A static template is defined by using script tag. It must has an
id
attribute with a unique value and atype
attribute with valuetext/ng-template
. Also, a static template must be inside the scope of the ng-app directive otherwise it will be ignored by Angular.<script type="text/ng-template" id="person.html"> {{person.name}} : {{person.address}} </script>
A static template can be rendered by using ng-include directive.
<div ng-include="'person.html'"></div>
Full Example of Static Template
<!DOCTYPE html> <html> <head> <title>AngularJS Static Templates</title> <script src="lib/angular.js"></script> <script> //defining module var app = angular.module('app', []); app.controller("myController", function ($scope) { $scope.person = { name: "Deepak Chauhan", address: "Delhi" }; }); app.controller("homeController", function ($scope) { $scope.persons = [{ name: "Deepak Chauhan", address: "Delhi" }, { name: "Shailendra Chauhan", address: "Noida" }, { name: "Kuldeep Chauhan", address: "Gurgaon" }] }); </script> </head> <body ng-app="app"> <h1>AngularJS : Static Templates</h1> <!--It should be the part of ng-app directive--> <script type="text/ng-template" id="person.html"> {{person.name}} : {{person.address}} </script> <div ng-controller="myController"> <h1>myController</h1> <!--Please not the single quotes around person.html. The value of the ng-include is an expression and person.html is a string value, so put single quotes around it.--> <div ng-include="'person.html'"></div> </div> <div ng-controller="homeController"> <h1>homeController</h1> <div ng-repeat="person in persons" ng-include="'person.html'"></div> </div> </body> </html>
Dynamic Templates
A dynamic template is an html page which is compiled and rendered by Angular on demand. The above static template can be created as a HTML page within templates folder of your app like as:
person.html
{{person.name}} : {{person.address}}
A dynamic template can be rendered by using ng-include directive.
<div ng-include="'templates/person.html'"></div>
Full Example of Dynamic Template
<!DOCTYPE html> <html> <head> <title>AngularJS Dynamic Templates</title> <script src="lib/angular.js"></script> <script> //defining module var app = angular.module('app', []); app.controller("myController", function ($scope) { $scope.person = { name: "Deepak Chauhan", address: "Delhi" }; }); app.controller("homeController", function ($scope) { $scope.persons = [{ name: "Deepak Chauhan", address: "Delhi" }, { name: "Shailendra Chauhan", address: "Noida" }, { name: "Kuldeep Chauhan", address: "Gurgaon" }] }); </script> </head> <body ng-app="app"> <h1>AngularJS : Dynamic Templates</h1> <div ng-controller="myController"> <h1>myController</h1> <!--Please not the single quotes around person.html. The value of the ng-include is an expression and person.html is a string value, so put single quotes around it.--> <div ng-include="'templates/person.html'"></div> </div> <div ng-controller="homeController"> <h1>homeController</h1> <div ng-repeat="person in persons" ng-include="'templates/person.html'"></div> </div> </body> </html>
person.html
{{person.name}} : {{person.address}}
Note
Always put the single quotes around the name of template with ng-include directive, since it accept an expression. Hence to indicate to Angular that template (person.html) is a string value you have to put single quotes around it's name.
