change the text of the button on click using angular JS

Question

How I can change the text of the button on click of the button.

Here it is what I have tried.

HTML:

<button ng-click="toggle = !toggle">Toggle!</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>

JS:

function MainController($scope) {
  $scope.toggle = true;
}

Answer 1

Or, keep all the content in your HTML, rather than defining the button text in the controller, if you prefer:

<button ng-click="toggle = !toggle">
    <span ng-show="toggle">Toggle to Off</span>
    <span ng-hide="toggle">Toggle to On</span>
</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>

Answer 2

I think, using a watch of toggle should do it

<button ng-click="toggle = !toggle">{{toggleText}}</button>
<div class="box on" ng-show="toggle" ng-animate="'box'">On</div>

then

app.controller('AppController', function ($scope) {
    $scope.toggle = true;

    $scope.$watch('toggle', function(){
        $scope.toggleText = $scope.toggle ? 'Toggle!' : 'some text';
    })
})
