最近做項(xiàng)目需要這樣的需求，當(dāng)用戶點(diǎn)擊標(biāo)簽欄按鈕，向下彈出菜單，再次點(diǎn)擊，收回菜單。接下來通過本文給大家介紹微信小程序?qū)崿F(xiàn)彈出菜單功能，感興趣的朋友一起看看吧

需求

點(diǎn)擊標(biāo)簽欄按鈕，向下彈出菜單，再次點(diǎn)擊，收回菜單

要解決的問題

標(biāo)簽欄三欄樣式，標(biāo)簽欄固定不動(dòng)；
點(diǎn)擊標(biāo)簽欄彈出菜單，并且出現(xiàn)透明遮罩；
遮罩優(yōu)先級(jí)在彈出框之下；
彈出框內(nèi)標(biāo)簽的設(shè)置；
滾動(dòng)欄滾動(dòng)條的隱藏

如何解決？

彈性布局，橫向，三者平分整欄;
狀態(tài)監(jiān)聽點(diǎn)擊事件，數(shù)據(jù)控制hide或者show,通過rgba設(shè)置透明度
彈出框設(shè)置z-index；
彈性布局flex 橫向排列超出后wrap 然后space-around控制間距
