In the previous post, we learnt how to create a custom diretive that returns a templateUrl and bind the data. In this post, we shall learn how to change the templateUrl for the custom directive dynamically based on elements attribute.
Notice the <script> block code, we have defined a controller with $scope properties username and address.
Next we have created a directive named 'my-custom-url-function' (its normalized name is myCustomUrlFunction) whose return is specified as templateUrl that in tern return a function. In this function, we are returning the url based on the "number" attribute value.
<script>
var app = angular.module("app", [])
.controller("CustomDirectiveController", function ($scope) {
$scope.username = "SheoNarayan";
$scope.address = "Hyderabad, India";
});
app.directive('myCustomUrlFunction', function () {
return {
templateUrl: function (element, attribute) {
return '/DemoSupportingFiles/angular-MyView' + attribute.number + '.html';
}
};
});
</script>
<div ng-app="app" ng-controller="CustomDirectiveController">
<h2>function with templateUrl</h2>
<div my-custom-url-function number="1"></div>
<div my-custom-url-function number="2"></div>
</div>
The HTML code is preety simple and using the above created "my-custom-url-function" directive with "number" as attribute.
When the application runs, the first directive returns '/DemoSupportingFiles/MyView1.html' template file and second directive returns '/DemoSupportingFiles/MyView2.html' template file and shows the output in the browser.
MyView1.html
<h1>View 1</h1>
<table class="table">
<tr>
<th>Username</th>
<th>Address</th>
</tr>
<tr>
<td>{{username}}</td>
<td>{{address}}</td>
</tr>
</table>
MyView2.html
<h1>View 2</h1>
<table class="table">
<tr>
<th>Username</th>
<th>Address</th>
</tr>
<tr>
<td>{{username}}</td>
<td>{{address}}</td>
</tr>
</table>
Output
