Saya menulis sekeping kod js dan mendapati bahawa js asli yang ditulis dalam pengawal tidak berfungsi Mesej ralat menunjukkan bahawa fungsi tidak dapat ditemui Kod adalah seperti berikut: {kod...} Kemudian saya mendapati bahawa jika js asli diletakkan di luar domain kawalan pengawal, ia boleh Fungsi ditemui dan berjalan seperti biasa (di bawah) {kod.....

Soalan asas. Apabila dalam use strict 模式下， function ia harus diikuti tentukan dahulu kemudian gunakan .

Kemudian saya mendapati bahawa jika saya meletakkan js asli di luar domain kawalan pengawal, saya boleh mencari fungsi itu dan menjalankannya secara normal (seperti yang ditunjukkan di bawah)

    $scope.food_remarks = [];

    // 订单详情数组
    $scope.forms_detail = [];

    // 查询订单详情
    $scope.search_detail = function(index){  
        $scope.forms_detail = $scope.food_forms[index];
        $scope.food_remarks = $scope.food_forms[index].remarks;
        console.log($scope.forms_detail);
        // var form_num = $scope.forms_detail.order_number;
        $scope.food_detail = $scope.food_forms[index].food_detail;
        // console.log($scope.food_detail);
        for (var i = 0; i < $scope.food_detail.length; i++) {
            for (var j = 0; j < $scope.food_menu.length; j++) {
                if ($scope.food_detail[i].id == $scope.food_menu[j].id) {

                    $scope.food_detail[i].price = $scope.food_menu[j].price;

Apakah sebabnya? Dalam projek yang saya kerjakan sebelum ini, ada kemungkinan untuk menulis js asli dalam pengawal Saya tidak tahu mengapa ia tidak boleh digunakan kali ini
