一个字符替换过滤问题：如何将一个回车符转换成空格

[navysky]

<script language="javascript">
function FiltStr(s)
{
var s = s;
var start;
var lastStr;
s = s.replace(/(^\t*)|(\t*$)/g,"");
//s = s.replace(/\n*/g,"")
//s = s.replace(/\t\r\n/g,"")
//s = s.replace(/\r\n/g,"<br />").replace(/[\n|\r]/g,'<br />');

alert(s);

start = s.indexOf("（");
lastStr = s.slice(start+1,-1);
lastStr = lastStr.substr(0,10);
document.write(lastStr+" (" + s.length + ")");
}
</script>
<script language="javascript">FiltStr("


共同关注（迷失在网络的青...


");</script>

要是改成TAB键是可以的：<script language="javascript">FiltStr(" 共同关注（迷失在网络的青... ");</script>
不知道怎么将回车或换行符过滤出来
大伙儿帮我一下，谢谢！

var str="


共同关注（迷失在网络的青...


";

------------------------
上面赋值是错误的。
给字符串赋换行符是：
var str="\n \n \n共同关注（迷失在网络的青...\n"

\n 换行
\r 回车

那用其它的方式还有吗？

如果以上信息来自于数据库，请参考以下


字符串从数据库里读到页面时，通常要经过处理。
比如果<input value="aaaa">如果数据库里的值是aa"aa，不处理就直接使用的话，就会产生失真。
对于产生失真或的产生错误的特殊字符，都要进行处理。

Script里面的，可以这样调用
<%=CommStr.jsEncoder(yourString)%>
