第二次嘗試：<style(([/s/S])*?)</style> 成功
匹配<div>只需要把<style>換成<div>即可
1. 只替換匹配到的第一個(gè)<style>
var result= testData.replace(<style(([/s/S])*?)<//style>, '');
2. 會(huì)替換所有testData中所有的<style>標(biāo)簽
var result= testData.replace(/<style(([/s/S])*?)<//style>/g, '');
g：代表可以進(jìn)行全局匹配。
i：代表不區(qū)分大小寫匹配。
m：代表可以進(jìn)行多行匹配。
以上內(nèi)容是小編給大家介紹的JavaScript正則表達(dá)式匹配<div><style>標(biāo)簽，希望對(duì)大家有所幫助！
