简介 asp中实现清除html的函数_应用技巧_
这个函数是必需要的，很多黑客来捣乱，黑掉数据库，会注入大量的病毒js，在存储和展示文本数据的时候，使用此函数过滤一下，可避免不少麻烦
clearhtml代码
'清除HTML代码 function clearhtml(content) content=replacehtml("&#[^>]*;","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml(" ","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("(javascript|jscript|vbscript|vbs):","",content) content=replacehtml("on(mouse|exit|error|click|key)","",content) content=replacehtml("<\\?xml[^>]*>","",content) content=replacehtml("<\/?[a-z]+:[^>]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) content=replacehtml("]*>","",content) clearhtml=content end functionreplacehtml代码
function replacehtml(patrn,strng,content) if isnull(content) then content="" end if set regex=new regexp regex.pattern=patrn regex.ignorecase=true regex.global=true replacehtml=regex.replace(content,strng) end function
使用方法：
复制代码 代码如下:
<%=clearhtml("
分享代码提示(2)
- 添加完代码必须点击“完成并查看”生效
- 准确的编程语言，可正确对代码语法着色
- 输入简单几个字的代码片段说明
- 上传源码文件时无需再输入说明
- 非程序相关文件将直接删除，严重封帐号
- 图片仅用来上传截图之类的文件，勿作他途
以上就是本文所述的全部内容了，希望大家能够喜欢。
