Question

我正在使用http://jscs.info。如果我的应用程序留下尾随逗号，我需要收到警告，例如，使用：

var x = {
    prop1: 10,
    prop2: 20,
};

我应该收到警告。使用以下设置：

disallowTrailingComma true
requireTrailingComma true

我无法得到警告。

我在这里做错了什么？

Answer 1

你的两个选择相互矛盾。同时，您要求使用"requireTrailingComma": true的尾随逗号，并禁止使用"disallowTrailingComma": true跟踪逗号。

要获取尾随逗号的警告，请移除"requireTrailingComma": true选项，同时保留"disallowTrailingComma": true。

<强>更新

我删除了以下在控制台中生成错误的选项，它适用于稍微修改过的示例代码，只显示尾随逗号警告：

var x ={
    prop1 : 10,
    prop2 : 20,
};

我删除了以下行（与错误一起显示）

"disallowSpaceAfterLineComment": false

因为

AssertionError: disallowSpaceAfterLineComment option requires the value true

和

"safeContextKeyword": true

，因为

AssertionError: safeContextKeyword option requires string or array value

和

"requireTrailingComma": true

因为上述矛盾。

disallowTrailingComma在jscs中不起作用
