Javascript doesn't support Unicode classes of the form \p{IsCyrillic}.

Javascript不支持表单\p{IsCyrillic}的Unicode类。

But, assuming the characters you want to replace are in the Unicode Cyrillic range 0400 - 04FF, you could use:

但是，假设您想要替换的字符在Unicode Cyrillic范围0400 - 04FF中，您可以使用:

newstr = strInput.replace( /[\u0400-\u04FF]/gi, '' );

For example:

例如:

    var strInput = 'уфхцчшщъhelloЁЂЃЄрстыьэю',
        newstr = strInput.replace( /[\u0400-\u04FF]/gi, '' ); 

    console.log( newstr );    //  'hello'

I think that JavaScript RegEx does not support this syntax.

我认为JavaScript RegEx不支持这种语法。

May be this will help?

这会有帮助吗?

Another way:

另一种方法:

Pattern.compile("[А-я]+", Pattern.UNICODE_CHARACTER_CLASS).matcher(strInput ).replaceAll("") ;

Where [А-я]+ is your alphabet.

[А-я]+你的字母。
