错误:未能识别属性“`Script`”的值‘for’

Question

我正在尝试从字符串中过滤汉字。

根据这个答案的说法，我可以：

const nonChinese = /[^\p{Script=Han}]/gimu;
const text = "asdP asfasf这些年asfagg 我开源的 几个小项目sad asd";
console.log(text.replace(nonChinese, ""));

预期产出：

"这些年我开源的几个小项目"

这可以在js：js小提琴操场这样的在线编译器中工作，但是它不适用于我的NextJs (带有类型脚本)应用程序，它会给我一个编译错误：

Error: Failed to recognize value `Han` for property `Script`.

引发此错误的原因如下：

我能知道为什么会发生这种事，以及如何解决吗？

Answer 1

嗯，不知道为什么，但在我把正则表达式改为：

const nonChinese = /[\P{Script=Han}]/gim

它只是起作用了，如果有人仍然面临这个问题，而你只有ASCII和汉字，你可以使用一个替代方案，过滤掉所有的ASCII字符。

const allAscii = /[\x00-\x7F]/gim
