：<textarea id=main_editer onKeyDown="return ctlent();" onKeyUp=javascript:main_editer_Keyup(); onClick="javascript: storeCaret

(this);" " name=main_editer rows=14 cols=60 onSelect="javascript: storeCaret(this);">
<p>[M][fts=6][ftf=wingdings][ffg,999999,00FFFF]R[/ft][/ft][/ft]－/は[[U][ffg,999999,00FFFF]厦天[/ft][/U]〕の,<br />－/[U]

</textarea>。。
<br />是有空格的....<br空格/>替换成<br/>

<input type="button" onclick='rep()' value='替换' />
<textarea id=sub_editer rows=14 cols=60 ></textarea>

<script>
function rep()
{
var d = document.getElementById("main_editer");
var d1 = document.getElementById("sub_editer");

val = d.value;

val = val.replace(/<br[^>]*\/>/gi, "<br/>");
d1.value = val;
}
</script>

//使用正则, 忽略大小写, 将所有的 <br(任意非>字符)/>都替换成<br/>

Answer 2

不需要JS
text=replace(replace(replace(replace(replace(request.form("text"),"<",""),">",""),chr(32),""),"script",""),chr(13),"<BR>")
包括回车 空格 等

<textarea name="area" cols='18' rows="3" onchange="replaceChar(this.value)">

js文件:

function replaceChar(Str)
{
var getStr = "";
while(Str.indexOf("<br/>") > 0)
{
getStr = replace("<br/>","<br>")
}
document.getElementByName("area").value = getStr;
}
