我的页面上有一个按钮,页面上有一个 id="viewQuestions":
<body ng-keydown="key($event);">
我的代码正在检查这样的键命中:
$scope.key = function ($event) {
$scope.$broadcast('key', $event.keyCode)
}
在控制器中:
$scope.$on('key', function (e, key) {
if (key == 13) {
if (ts.test.current && ts.test.userTestId) {
document.getElementById("viewQuestions").click();
}
}
});
当我运行代码并单击 ENTER 时,我收到此错误:
Error: [$rootScope:inprog] $apply already in progress

谁能给我这方面的建议。我只想模拟按下 ENTER 键时单击按钮。我确实尝试过使用表单的解决方案,但它不能满足我相当复杂的需求。
