简单的Html转换UBB的程序

整理编辑:建站学习网 更新时间:2017-04-14 阅读:0

这个功能主要是让 UBB 转贴的时候方便点. 

1.自动识别图片,超链接,字体颜色,和字体加粗,倾斜,下划线的HTML代码,并且转换为UBB代码.
2.兼容 IE 和 Mozilla多种浏览器
<html> 
<head> 
<title>Html转换程序</title> 
<SCRIPT language="JavaScript1.2"> 
function HtmlToUBB(str) { 
str = str.replace(/r/g,""); 
str = str.replace(/on(load|click|dbclick|mouseover|mousedown|mouseup)="[^"]+"/ig,""); 
str = str.replace(/<script[^>]*?>([wW]*?)</script>/ig,""); 
str = str.replace(/<a[^>]+href="([^"]+)"[^>]*>(.*?)</a>/ig,"n[url=$1]$2[/url]n"); 
str = str.replace(/<font[^>]+color=([^ >]+)[^>]*>(.*?)</font>/ig,"n[color=$1]$2[/color]n"); 
str = str.replace(/<img[^>]+src="([^"]+)"[^>]*>/ig,"n[img]$1[/img]n"); 
str = str.replace(/<([/]?)b>/ig,"[$1b]"); 
str = str.replace(/<([/]?)strong>/ig,"[$1b]"); 
str = str.replace(/<([/]?)u>/ig,"[$1u]"); 
str = str.replace(/<([/]?)i>/ig,"[$1i]"); 
str = str.replace(/ /g," "); 
str = str.replace(/&/g,"&"); 
str = str.replace(/"/g,"""); 
str = str.replace(/</g,"<"); 
str = str.replace(/>/g,">"); 
str = str.replace(/<br>/ig,"n"); 
str = str.replace(/<[^>]*?>/g,""); 
str = str.replace(/[url=([^]]+)]n([img]1[/img])n[/url]/g,"$2"); 
str = str.replace(/n+/g,"n"); 
return str;
