Adding Angular Components Dynamically to HTML Using a String, and Initializing with Bootstrap Framework

I am interested in achieving the following:

Here is a snippet of code that I have:

<body ng-app="MyApp">
<div id="content"><button onclick="addCode()">Add Code</button></div>
</body>

The function "addCode()" does this using jQuery:

function addCode(){
  $("content").html("<hello-world></hello-world>");
}

The hello-world tag represents an angular component and has the following code:

'use strict';
        angular.module('MyApp', []).component('helloWorld', {
            templateUrl: 'template.html',
            controller: function () {
                this.greet = 'Hello World';
            }
});

Furthermore, the template.html contains the following code:

<p>{{$ctrl.greet}}</p>

I am wondering how to trigger the application after clicking the button so that "Hello World" appears in the web page instead of {{$ctrl.greet}} inside the paragraph.

In simpler terms, I want Angular to reload or re-bootstrap the document to dynamically load components tags.

This solution works perfectly when setting

<body><hello-world></hello-world></body>
and loading the document. However, I aim to set the component and load it after the webpage has initially loaded.

Answer №1

If you're making modifications to the DOM without using Angular, it's important to inform Angular about these changes. One way to do this is by using the $scope.$digest() method.

ISSUE RESOLVED!

After some trial and error, I was finally able to crack the code. It wasn't as challenging as I thought it would be.

In your script:

angular.module('MyApp', []).component('helloWorld', {
        templateUrl: 'template.html',
        controller: function ($http) {
            var ctrl = this;
            ctrl.updateHello = function (str) {                    
                ctrl.greet = 'Hello '+str;
            };
            ctrl.updateHello('World')
        }
});

In your HTML template:

<button class="ng-binding" ng-click="$ctrl.updateHello ('Angular')">UPDATE</button>
<div>{{$ctrl.greet}}</div>

In your HTML main file or layout:

<hello-world></hello-world>

:)
