我如何在Firefox中使用Angularjs中的事件，因为它表示事件未定义？

Question

Here's my Angular function which basically updates data when you double-click on the required field, change it's value and press enter:

 $scope.contentEdit = function(data, event) {
    console.log("event", event); //this function triggers when the user edit student's data from the table and updates new data to local storage.
    for (var i = 0; i < $scope.students.length; i++) {
        if ($scope.students[i].studentName == data) {
            $scope.students[i].studentName = event.target.innerText;
        } else if ($scope.students[i].Marks == data) {
            $scope.students[i].Marks = parseInt(event.target.innerText);
            $scope.students[i].pass = ($scope.students[i].Marks > 65) ? true : false;
        }
    }
    localStorage.setItem('studentsList', JSON.stringify($scope.students));
    event.target.contentEditable = event.target.contentEditable == "false" ? "true" : "false";
};

I have passed $event from my html as contentEdit(student.studentName, $event) but it still doesn't work. Whenever I double click on the field then it's logging the double click event successfully on console but as soon as I hit Enter key, It's throwing and error that event is undefined.

Do you use a ng-dblclick directive? If yes, I suppose you has a syntax error.

 var app = angular.module('myApp', []); app.controller('myCtrl', function($scope) { $scope.contentEdit = function(data, event) { console.log(event); }; }); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myCtrl"> <div ng-dblclick="contentEdit(1, $event)">dblclick me to see the console</div> </div>
