我發(fā)現(xiàn)這種使用Unicode 屬性轉(zhuǎn)義的不使用“巨大魔法范圍”的正則表達(dá)式來(lái)檢測(cè)表情符號(hào)的絕妙方法：console.log(/\p{Emoji}/u.test('flowers???????'))?//?true console.log(/\p{Emoji}/u.test('flowers'))?//?false注意到它\p{Emoji}也匹配數(shù)字！這是為什么？數(shù)字不是表情符號(hào)？console.log(/\p{Emoji}/u.test('flowers 123')) // unexpectdly true// regex-only workaround by @Bonzdragonconst regex = /(?=\p{Emoji})(?!\p{Number})/u;console.log(? regex.test('flowers'), // false, as expected? regex.test('flowers 123'), // false, as expected? regex.test('flowers 123 ??????'), // true, as expected? regex.test('flowers ??????'), // true, as expected)// more readable workaroundconst hasEmoji = str => {? const nbEmojiOrNumber = (str.match(/\p{Emoji}/gu) || []).length;? const nbNumber = (str.match(/\p{Number}/gu) || []).length;? return nbEmojiOrNumber > nbNumber;}console.log(? hasEmoji('flowers'), // false, as expected? hasEmoji('flowers 123'), // false, as expected? hasEmoji('flowers 123 ??????'), // true, as expected? hasEmoji('flowers ??????'), // true, as expected)
