這篇文章主要介紹了JavaScript正則表達(dá)式匹配<div><style>標(biāo)簽 的相關(guān)資料,需要的朋友可以參考下

測(cè)試字符串：

<style>v\:* {

BEHAVIOR: url(#default#VML)

} o\:*

{

BEHAVIOR: url(#default#VML)

} w\:*

{

BEHAVIOR: url(#default#VML)

}

.shape

{

BEHAVIOR: url(#default#VML)

}

</style>

第一次嘗試：<style[^>/]*>(.*?)</style> 發(fā)現(xiàn)有換行的情況匹配不了，因?yàn)?是匹配除了換行符（/n）以外的任意一個(gè)字符。

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！
