测试字符串：

<style>v:* { BEHAVIOR: url(#default#VML) } o:* { BEHAVIOR: url(#default#VML) } w:* { BEHAVIOR: url(#default#VML) } .shape { BEHAVIOR: url(#default#VML) } </style> abcdefg <style> @font-face { font-family: Wingdings; } @font-face { font-family: Wingdings; } @font-face { font-family: Calibri; } @font-face { font-family: Tahoma; } @page WordSection1 {size: 8.5in 11.0in; margin: 1.0in 1.0in 1.0in 1.0in; } P.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman","serif" } LI.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman","serif" } DIV.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman","serif" } H1 { FONT-WEIGHT: bold; FONT-SIZE: 24pt; MARGIN-LEFT: 0in; MARGIN-RIGHT: 0in; FONT-FAMILY: "Times New Roman","serif"; mso-style-priority: 9; mso-style-link: "Heading 1 Char"; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto } A:link { COLOR: blue; TEXT-DECORATION: underline; mso-style-priority: 99 } SPAN.MsoHyperlink { COLOR: blue; TEXT-DECORATION: underline; mso-style-priority: 99 } A:visited { COLOR: purple; TEXT-DECORATION: underline; mso-style-priority: 99 } SPAN.MsoHyperlinkFollowed { COLOR: purple; TEXT-DECORATION: underline; mso-style-priority: 99 } P { FONT-SIZE: 12pt; MARGIN-LEFT: 0in; MARGIN-RIGHT: 0in; FONT-FAMILY: "Times New Roman","serif"; mso-style-priority: 99; mso-margin-top-alt: auto; mso-margin-bottom-alt: auto } P.MsoAcetate { FONT-SIZE: 8pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Tahoma","sans-serif"; mso-style-priority: 99; mso-style-link: "Balloon Text Char" } LI.MsoAcetate { FONT-SIZE: 8pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Tahoma","sans-serif"; mso-style-priority: 99; mso-style-link: "Balloon Text Char" } DIV.MsoAcetate { FONT-SIZE: 8pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Tahoma","sans-serif"; 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(([sS])*?)</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(([sS])*?)</style>, '');

2. 会替换所有testData中所有的<style>标签

var result= testData.replace(/<style(([sS])*?)</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！
