Menu
I have a button on my page with an id="viewQuestions" on a page:
<body ng-keydown="key($event);">
My code is checking for key hits like this:
$scope.key = function ($event) {
$scope.$broadcast('key', $event.keyCode)
}
and in the controller:
$scope.$on('key', function (e, key) {
if (key == 13) {
if (ts.test.current && ts.test.userTestId) {
document.getElementById("viewQuestions").click();
}
}
});
When I run the code and click ENTER then I get this error:
Error: [$rootScope:inprog] $apply already in progress

Can anyone give me advice on this. I just want to simulate the clicking of a button when the ENTER key is pressed. I did try solutions with forms but it does not meet my rather complicated needs.

Your click event is running digest cycle which is conflicting with current digest cycle, $timeout would help you in this situation. Wrap click event inside $timeout function.
Markup
<body ng-app="myApp" ng-controller="testCtrl" ng-keydown="key($event);">
<button id="viewQuestions" type="button" ng-click="isButtonClicked = !isButtonClicked; test();"> Test</button>
Is Button Clicked {{isButtonClicked}}
</body>
Code
$scope.$on('key', function (e, key) {
if (key == 13) {
if (ts.test.current && ts.test.userTestId) {
$timeout(function(){
angular.element(document.getElementById("viewQuestions")).trigger('click');
})
}
}
});
Whatever you write inside ng-click will get called.
