Using AngularJS and the ng-show directive, you can set a <div> element to

Objective: My aim is to show the content of a div according to the status of checkboxes, while also ensuring that these divs are visible by default

If I have this code snippet:

<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js"></script>
</head>
<body ng-app>
<label>red <input type="checkbox"  ng-model="red"  /></label><br />
<label>blue <input type="checkbox"  ng-model="blue"   /></label><br />
<div ng-show="red" style="width: 50px; height: 50px; background-color: red;"></div><br />
<div ng-show="blue" style="width: 50px; height: 50px; background-color: blue;"></div><br />
<div ng-show="red" style="width: 50px; height: 50px; background-color: red;"></div><br />
</body>
</html>

In this code, my checkboxes are not pre-selected and each div appears correctly when one of the checkboxes is checked.

Next, I attempted to add:

ng-checked='true'

Now my checkboxes are initially checked, but the divs remain hidden. I tried experimenting with ng-init, ng-hide, or ng-load, but my knowledge of Angular is quite limited.

Could someone guide me in the right direction?

Answer №1

This solution appears to be effective.

<label>blue <input type="checkbox"  ng-model="blue" ng-init="blue=true" /></label><br />

Answer №2

ng-checked should not be combined with ng-model

If you need to update a checkbox, modify its model value like this:

$scope.red=true;

Remember to use an object in ng-model to avoid binding issues caused by child scopes
