本文實例講述了js過濾HTML標籤的方法。分享給大家參考,具體如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
<html xmlns= "http://www.w3.org/1999/xhtml" >
<head>
<meta http-equiv= "Content-Type" content= "text/html; charset=utf-8" />
<title>无标题文档</title>
<script>
window.onload= function ()
{
var oTxt1=document.getElementById( 'txt1' );
var oTxt2=document.getElementById( 'txt2' );
var oBtn=document.getElementById( 'btn' );
oBtn.onclick= function ()
{
var reg=/<[^<>]+>/g;
oTxt2.value=oTxt1.value.replace(reg, '' );
};
};
</script>
</head>
<body>
<textarea id= "txt1" cols= "40" rows= "10" ></textarea><br />
<input type= "button" value= "过滤" id= "btn" /><br />
<textarea id= "txt2" cols= "40" rows= "10" ></textarea>
