网站中发表一些文章或帖子的时候，文字填到了<textarea>中，提交存入数据库后，当在前台浏览器中显示的时候，其中的空格和回车处理有什么最好的办法吗？默认时将那些空格都不显示，回车也不起作用，替换成<br>, ？？？文章很长时呢？大概有好几万字
s=s.replaceAll("[\n]","<br>");
s=s.replaceAll(" "," ");
这样用
<%!
public static String repstr(String str, String strDen, String strSrc)
{
int iLen = str.length();
int iDenLen = strDen.length();
int iSrcLen = strSrc.length();
String strReturn = "";
int iSearchedFrom = 0 ;
int iPrevSearchedFrom = 0;
while ( (iSearchedFrom = str.indexOf(strSrc , iSearchedFrom)) != -1 )
{
strReturn += str.substring(iPrevSearchedFrom, iSearchedFrom);
strReturn += strDen;
iSearchedFrom += iSrcLen;
iPrevSearchedFrom = iSearchedFrom;
}
if ( iPrevSearchedFrom !=0 )
strReturn += str.substring( str.lastIndexOf(strSrc) + iSrcLen , str.length());
else
strReturn = str;
return(strReturn);
}
%>
<%!
String DoWhiteSpace(String str)
{
str=repstr(str," "," ");
str=repstr(str,"<br>","\r");
return (str);
}
%>
