正则表达式如何过滤HTML标签中的属性值_随笔

1、过滤所有html标签的属性的正则表达式：

$search = array ("'<script[^>]*?>.*?</script>'si", // 去掉 JavaScript

"'<[\/\!]*?[^<>]*?>'si", // 去掉 HTML 标记

"'([\r\n])[\s]+'",// 去掉空白字符

"'&(quot|#34)'i",// 替换 HTML 实体

"'&(amp|#38)'i",

"'&(lt|#60)'i",

"'&(gt|#62)'i",

"'&(nbsp|#160)'i"

) // 作为 PHP 代码运行

$replace = array ("","","\\1","\"","&","<",">"," ")

$html = preg_replace($search, $replace, $html)

顶

<!DOCTYPE html>

<head>

window.onload = function() {

var oTxt1 = document.getElementById('txt1')

var oTxt2 = document.getElementById('txt2')

var test = document.getElementById('test')

test.onclick = function() {

var reg = /<[^<>]+>/g

oTxt2.value = oTxt1.value.replace(reg, '')

}

</script>

</head>

<body>

<div>

</div>

</body>

</html>
