Concealing and revealing elements in AngularJS with ng-hide and ng

Currently diving into AngularJS and encountering a hiccup with the "ng-hide" directive, as it's not functioning properly.

Here's the snippet of my HTML code:

<!DOCTYPE html>

<html>
<head>
    <meta charset="utf-8">
    <title>Testing ng-hide/ng-show</title>
</head>
<body>
    <p ng-hide="true">I'm invisible</p>
    <p ng-show="true">I'm visible</p>
</body>

Attached is the script for Angular:

http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js (embedded within "script" tags)

javascriptangularjsng-showng-hide

Answer №1

In order to start your program, you must first initialize it. Include ng-app in your html file.

<html ng-app="MyApp">
...

Next, establish your application module

<script>
    var myApp = angular.module("MyApp", []);
</script>

Answer №2

Your application is not bootstrapping correctly.

index.html

<!DOCTYPE html>
<html>

  <head>
    <link rel="stylesheet" href="style.css">
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
    <script src="script.js"></script>
  </head>

  <body ng-app="app"> <!-- Make sure to include this -->
    <p ng-hide="true">I'm hidden</p>
    <p ng-show="true">I'm shown</p>
  </body>

</html>

script.js

var app = angular.module('app', []); // Don't forget to add this line

Plunker

Answer №3

At this point, the page hasn't been compiled by the angular compiler. To fix this, you'll need to include the ng-app directive (which usually specifies the module name) in your code.

Code Example:

<body ng-app="">
    <p ng-hide="true">I'm hidden</p>
    <p ng-show="true">I'm shown</p>
</body>

See Demo Plunkr for a visual example.

In a more technical sense, it's important to create a module and add components to that module (especially in an enterprise setting).

Answer №4

Hey Jose, don't forget to declare your page as an Angular application.

<html lang="en" ng-app="myApp">

Also, be sure to initialize your app in the JavaScript file:

angular.module('myApp', []);
