简介：Html转UBB的JS版本【寻求更好的方案】

转换部分，存在BUG。。。

------------------------------------------------------------------------------------------------------------------------------------------------------

Html代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>HtmlUbbTranslation</title>

<script src="js/Html_Ubb.js" type="text/javascript"></script>

</head>
<body>
<form id="form1" runat="server">
<div style="padding: 5px; text-align: center;">
<div>
<div>
请将 <strong>Html</strong> 源代码拷贝到下面表单中:
</div>
<div>
<textarea id="Hsource" cols="15" rows="15" style="width: 700px;" onkeyup="htmltoubb()"
onfocus="htmltoubb()"></textarea>
</div>
<span>下面表单中是相应的 <strong>UBB</strong> 代码: </span>
<br>
<span>
<textarea id="Uresult" cols="15" rows="15" style="width: 700px;"></textarea>
</span>
</div>
</div>
</form>
</body>
</html>

JavaScript脚本：

function htmltoubb(){
str = pattern(document.getElementById("Hsource").value);
document.getElementById("Uresult").value=str;
}

function pattern(str){
//str = str.replace(/(\r\n|\n|\r)/ig, '');
str = str.replace(/<br[^>]*>/ig,'\n');
str = str.replace(/<p[^>\/]*\/>/ig,'\n');
//str = str.replace(/\[code\](.+?)\[\/code\]/ig, function($1, $2) {return phpcode($2);});
str = str.replace(/\son[\w]{3,16}\s?=\s*([\'\"]).+?\1/ig,'');

str = str.replace(/<hr[^>]*>/ig,'[hr]');
str = str.replace(/<(sub|sup|u|strike|b|i|pre)>/ig,'[$1]');
str = str.replace(/<\/(sub|sup|u|strike|b|i|pre)>/ig,'[/$1]');
str = str.replace(/<(\/)?strong>/ig,'[$1b]');
str = str.replace(/<(\/)?em>/ig,'[$1i]');
str = str.replace(/<(\/)?blockquote([^>]*)>/ig,'[$1blockquote]');

str = str.replace(/<img[^>]*smile=\"(\d+)\"[^>]*>/ig,'[s:$1]');
str = str.replace(/<img[^>]*src=[\'\"\s]*([^\s\'\"]+)[^>]*>/ig,'');
str = str.replace(/<a[^>]*href=[\'\"\s]*([^\s\'\"]*)[^>]*>(.+?)<\/a>/ig,''+'$2'+'');
//str = str.replace(/<h([1-6]+)([^>]*)>(.*?)<\/h\1>/ig,function($1,$2,$3,$4){return h($3,$4,$2);});

str = str.replace(/<[^>]*?>/ig, '');
str = str.replace(/&/ig, '&');
str = str.replace(/</ig, '<');
str = str.replace(/>/ig, '>');

return str;
}

function up(str){

str = str.replace(/</ig,'<');
str = str.replace(/>/ig,'>');
str = str.replace(/\n/ig,'<br />');
str = str.replace(/\[code\](.+?)\[\/code\]/ig, function($1, $2) {return phpcode($2);});

str = str.replace(/\[hr\]/ig,'<hr />');
str = str.replace(/\[\/(size|color|font|backcolor)\]/ig,'</font>');
str = str.replace(/\[(sub|sup|u|i|strike|b|blockquote|li)\]/ig,'<$1>');
str = str.replace(/\[\/(sub|sup|u|i|strike|b|blockquote|li)\]/ig,'</$1>');
str = str.replace(/\[\/align\]/ig,'</p>');
str = str.replace(/\[(\/)?h([1-6])\]/ig,'<$1h$2>');

str = str.replace(/\[align=(left|center|right|justify)\]/ig,'<p align="$1">');
str = str.replace(/\[size=(\d+?)\]/ig,'<font size="$1">');
str = str.replace(/\[color=([^\[\<]+?)\]/ig, '<font color="$1">');
str = str.replace(/\[backcolor=([^\[\<]+?)\]/ig, '<font style="background-color:$1">');
str = str.replace(/\[font=([^\[\<]+?)\]/ig, '<font face="$1">');
str = str.replace(/\[list=(a|A|1)\](.+?)\[\/list\]/ig,'<ol type="$1">$2</ol>');
str = str.replace(/\[(\/)?list\]/ig,'<$1ul>');

str = str.replace(/\[s:(\d+)\]/ig,function($1,$2){ return smilepath($2);});
str = str.replace(/\[img\]([^\[]*)\[\/img\]/ig,'<img src="$1" border="0" />');
str = str.replace(/\[url=([^\]]+)\]([^\[]+)\[\/url\]/ig, '<a href="$1">'+'$2'+'</a>');
str = str.replace(/\[url\]([^\[]+)\[\/url\]/ig, '<a href="$1">'+'$1'+'</a>');
return str;
}

function ubbtohtml(){
str = up(document.getElementById("Usource").value);
document.getElementById("Hresult").value=str;
}
