Enable/disable button based on radio button selection in AngularJS
angularjs
Solution
ngRepeat creates a new scope, which is a child scope of the scope used by the button. You can fix it by using
<input type="radio" ng-model="$parent.companyId" .../>
See http://jsfiddle.net/UZkM8/1/
But a better solution would be to update an object that is already in the scope:
$scope.userChoice = {};
<input type="radio" ng-model="userChoice.companyId" .../>
<button ng-disabled="!userChoice.companyId">Continue</button>
See http://jsfiddle.net/UZkM8/3/
Problem
I have items in a radio button list (using `ng-repeat`) with a `button` (initially disabled with `ng-disabled`) to continue. When a radio button is selected, I want to enable the "Continue" button. What's the right way to do this in Angular? Relevant JS: ``` $scope.companies = [{ "id": 3, "name": "Twitter" }, { "id": 2, "name": "Google" }, { "id": 1, "name": "Apple" }] ``` Relevant HTML: ``` <table> <tr ng-repeat="company in companies"> <td> <input type="radio" ng-model="companyId" name="companyId" value="{{company.id}}" />{{company.name}} </td> </tr> </table> <button ng-disabled="!companyId">Continue</button> ``` Jsfiddle Thanks!
