我知道这有点混乱，（主要代码只是来自w3schools的一个示例应用程序）但它显示了我想要做的事情。所以我有一个键盘应用程序，我带入文件（ng-include），它看起来非常奇妙。我的问题是$scope未得到承认。我已经阅读了“理解范围”github文档，但对我来说，这只是一点点。如果有人可以解释我需要做些什么以确保我的所有$scope函数实际起作用，我会非常感激。

正如Fissio在评论中所说，你在控制器之外声明了一个范围函数：

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
    $scope.firstName = "John";
    $scope.lastName = "Doe";
});
/**** see this here ****/
$scope.insertString = function(letter) {
        //$scope.name = $scope.name + letter;
        $scope.name = [$scope.name.slice(0,$scope.cursorPosVal),letter,$scope.name.slice($scope.cursorPosVal)].join('');
        console.log($scope.name);

        setTimeout(function(){ setCaretPosition("inputBox", $scope.cursorPosVal); }, 30);
    };

这就是你需要的：

var app = angular.module('myApp', []);
    app.controller('myCtrl', function($scope) {
        $scope.firstName = "John";
        $scope.lastName = "Doe";
        $scope.insertString = function(letter) {
            //$scope.name = $scope.name + letter;
            $scope.name = [$scope.name.slice(0,$scope.cursorPosVal),letter,$scope.name.slice($scope.cursorPosVal)].join('');
            console.log($scope.name);

            setTimeout(function(){ setCaretPosition("inputBox", $scope.cursorPosVal); }, 30);
        };
    });

您不能在控制器之外使用关键字$scope，因为它绑定到您的控制器。当它在外面的角度不会知道它是什么，这就是为什么它会说它不被识别的东西

使用ng-include时如何使作用域功能起作用？
