“所有JavaScript的列表”；未捕获的语法错误：无效的正则表达式“；信息

是否在任何地方维护了所有可能的JavaScript正则表达式语法冲突错误消息的综合列表

try {
    new RegExp(pattern);
} catch (e) {
    console.log(e.message);
}

例如，一些可能的错误消息如下：

Uncaught SyntaxError: Invalid regular expression: /(/: Unterminated group
Uncaught SyntaxError: Invalid regular expression: /+/: Nothing to repeat
Uncaught SyntaxError: Invalid regular expression: /\/: \ at end of pattern

---

这取决于javascript引擎

例如，对于v8引擎浏览器，请检查

搜索此模式

ReportError（CStrVector）（

查找所有错误

---

对于在解析器中作为指针引用的消息也是如此。

也适用于解析器中作为指针引用的消息。

这样的列表有什么用途？这将是特定于浏览器的。可能您必须筛选引擎的源代码。用例是了解在正则表达式验证程序模式窗口中显示的错误原因的最大长度，以便调整估计值。这确实需要upd在新的ES 2018功能之后使用ate。这样的列表有什么用途？这将是特定于浏览器的。可能您必须筛选引擎的源代码。用例是要知道在正则表达式验证器模式窗口中显示错误原因的最大长度，以便调整估计值。这确实需要在新的ES 2018功能之后进行更新s、 谢谢！这就是我最后要做的。谢谢！这就是我最后要做的。
