本文实例讲述了js过滤HTML标签的方法。分享给大家供大家参考,具体如下:
<!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></body></html>希望本文所述对大家JavaScript程序设计有所帮助。
