The ng-if directive in AngularJS seems to be malfunctioning

Could someone please help me understand why my "Voted:" checkbox is not controlling the ng-if directive? Strangely enough, the "Keep HTML" checkbox is working fine.

<p>
  <li ng-repeat="x in info">
    {{x.name}} Voted:
    <input type="checkbox"
      ng-model="myVar"
      ng-init="myVar =true">
  </li>
</p>

<input type="checkbox" ng-model="myVar" ng-init="myVar =true">
<h1 ng-if="myVar">Welcome2</h1>
<script>
  var app = angular.module("myApp", []);
  app.controller("myCtrl", function($scope) {
    $scope.myObj = {
      "color": "white",
      "background-color": "coral",
      "font-size": "60px",
      "padding": "50px"
    }

    $scope.info = [{
      name: 'woon',
      age: '18'
    },
    {
      name: 'amir',
      age: '17'
    }];
  });
</script>

Answer №1

To show or hide content in Angular, make use of ng-show directive. Here's a simple example:

ng-show="isVisible"

Answer №2

Avoid utilizing template variables in this scenario; instead, opt for scope.myVar to allow for flexible changes. It's important to note that myVar is located outside of the loop, presenting you with two potential solutions:

1) If the value is being calculated, consider extracting it within the JavaScript section. 2) If you need to display an input for every record in the array, consider moving that input into the loop.
