    } DIV.MsoAcetate
    {

    mso-style-priority: 99; mso-style-link: "Balloon Text Char"
    }
    SPAN.Heading1Char
    {
    FONT-WEIGHT: bold; mso-style-priority: 9; mso-style-link: "Heading 1"; mso-style-name: "Heading 1 Char"
    }
    SPAN.EmailStyle19 {
    COLOR: #1f497d; FONT-FAMILY: "Arial","sans-serif"; mso-style-type: personal-reply
    } SPAN.BalloonTextChar
    {
    FONT-FAMILY: "Tahoma","sans-serif"; mso-style-priority: 99; mso-style-link: "Balloon Text"; mso-style-name: "Balloon Text Char"
    }
    .MsoChpDefault {
    FONT-SIZE: 10pt; mso-style-type: export-only
    } DIV.WordSection1 {
    page: WordSection1 } OL
    {
    MARGIN-BOTTOM: 0in } UL
    {
    MARGIN-BOTTOM: 0in
    }
    </style>
    第一次尝试：<style[^>/]*>(.*?)</style> 发现有换行的情况匹配不了，因为.是匹配除了换行符（/n）以外的任意一个字符。
    第二次尝试：<style(([\s\S])*?)</style> 成功
    匹配<div>只需要把<style>换成<div>即可
    1. 只替换匹配到的第一个<style>
    var result= testData.replace(<style(([\s\S])*?)<\/style>, '');
    2. 会替换所有testData中所有的<style>标签
    var result= testData.replace(/<style(([\s\S])*?)<\/style>/g, '');
    g：代表可以进行全局匹配。
    i：代表不区分大小写匹配。
    m：代表可以进行多行匹配。
    以上内容是小编给大家介绍的JavaScript正则表达式匹配<div><style>标签，希望对大家有所帮助！
