当我运行我的 vxml 应用程序时，我得到了这个语法错误

Question

我在运行 vxml 应用程序时收到此错误；

"ECMAScript 运行时错误：编译产生 1 个语法 错误。\n\n评估时：\n\"var acc_no = [37492414, 94190610, 23228367, 39574988, 64742440];\n\t\t\t\t\tfunction checkAccount(arr, val) {\n\t\t\t\t\treturn arr.some(arrVal => val === arrVal);\n\t\t\t\t\t\t\t\t\t\t\t} \"";

我还是 vxml 和 ecmascript 的新手。

Answer 1

有问题的 ECMAScript 在语法上似乎是正确的：

var acc_no = [37492414, 94190610, 23228367, 39574988, 64742440];
                    function checkAccount(arr, val) {
                    return arr.some(arrVal => val === arrVal);
                                        }

我建议打破这种零碎的做法并降低 VXML 代码的复杂性来调试它。使用带有一个简单字段的非常基本的 VXML 文件，将上面的 ECMAScript 放入填充部分，然后查看是否出现相同的错误。如果这样做，请在代码中将脚本进一步向上移动（即不在填充部分中）并再次检查是否遇到相同的错误。

由于换行等原因，错误语句有点混乱。当您第一次看到错误消息时，它看起来像吗？
