关于HTML及UBB标记的闭合

代码还有待完善：
复制代码代码如下:<script type="text/javascript">
// Close HTML Tags --------------------------------------------
  function closeHTML（str）{
var arrTags=["span","font","b","u","i","h1","h2","h3","h4","h5","h6","p","li","ul","table","div"];

for（var i=0;i<arrTags.length;i++）{
var intOpen=0;
var intClose=0;

var  re=new RegExp（"\<"+arrTags[i]+"（ [^\<\>]+|）\>","ig"）;
var arrMatch=str.match（re）;
if（arrMatch！=null） intOpen=arrMatch.length;

re=new RegExp（"\<\/"+arrTags[i]+"\>","ig"）;
arrMatch=str.match（re）;
if（arrMatch！=null） intClose=arrMatch.length;

for（var j=0;j<intOpen-intClose;j++）{
str+="</"+arrTags[i]+">";
}
/*for（var j=（intOpen-intClose-1）;j>=0;j--）{
str+="</"+arrTags[i]+">";
}*/
}

return str;
}

// Close UBB Tags --------------------------------------------
function closeUBB（str）{
var arrTags=["code","quote","list","color","align","font","size","b"];

for（var i=0;i<arrTags.length;i++）{
var intOpen=0;
var intClose=0;

var  re=new RegExp（"\["+arrTags[i]+"（=[^\[\]]+|）\]","ig"）;
var arrMatch=str.match（re）;
if（arrMatch！=null） intOpen=arrMatch.length;

re=new RegExp（"\[\/"+arrTags[i]+"\]","ig"）;
arrMatch=str.match（re）;
if（arrMatch！=null） intClose=arrMatch.length;

for（var j=0;j<intOpen-intClose;j++）{
str+="[/"+arrTags[i]+"]";
}
}

return str;
}

alert（closeHTML（"正常:<div class="testBox"><ul><li><b>加粗</b><span>字体哈哈"））;
alert（closeHTML（"有错:<div class="testBox"><p><ul><li><b>加粗</b><span>字体哈哈"））;
</script>
