str=str.replace(/]*?>([wW]*?)/ig,"");
str=str.replace(/]+href="([^"]+)"[^>]*>(.*?)/ig,"n[url=$1]$2[/url]n");
str=str.replace(/]+color=([^>]+)[^>]*>(.*?)/ig,"n[color=$1]$2[/color]n");
str=str.replace(/]+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(/str=str.replace(/>/g,">");
str=str.replace(/

/ig,"n");
str=str.replace(/<[^>]*?>/g,"");
str=str.replace(/[url=([^]]+)]n([img]1[/img])n[/url]/g,"$2");
str=str.replace(/n+/g,"n");
returnstr;
}

functiontrans(){
varstr="";
str=document.getElementById('edit').contentWindow.document.body.innerHTML;
if(str.length==0){
alert("无转换内容！请使用Ctrl+V把内容复制到下面的编辑框内");
}
document.getElementById('ReCode').value=HtmlToUBB(str);
}

functionclearCode(){
document.getElementById('ReCode').value="";
}

functionStart(){
document.getElementById('edit').contentWindow.document.designMode="on";
try{
document.getElementById('edit').contentWindow.document.execCommand("undo",false,null);
}catch(e){
alert("你的Mozilla浏览器不支持在线RichEditor");
