how to display text with \n,\r in jsp from textarea?
I am wondering as how all these sites (like this Expert-Exchange, hotmail,
etc etc) works which are able to show all
kind of chars (KEEPING format) in your mail/postings. All these data are
entered in the TextField (like this one,
where a I am typing this content), which goes to some database (like Oracle
in mycase). And then they are able to
show the whole data back in some TextArea without any problem. I think if I
start taking care of each special char
for me (like new line, ', " etc) then there could be no end for my code. I
believe there should be some mechanism by
which whatever data you get from DB (Oracle) --> JSP Java String object -->
HTML TextArea and Vice-Versa without
loosing any data and preventing the "Unterminated string constant". I
believe that some sort of encoding and
decoding need to be done, but what those are? How all these sites do it.
Textarae:------
<tr>
<td>NOTES :-</td>
<td> <TEXTAREA Name="notes" rows="4"
cols="30"></TEXTAREA></td>
</tr>
JavaScript:----
var notes=document.Form.notes.value;
notes = notes.replace(/\n\r?/g, '<BR/>');
and saving it in db...as string..
and again retrivewing from db:------
notes = resultset.getString("notes");
notes = notes.replace("<BR/>","\n"); <--- is it corerect?
and displaying in jsp:----
<%
String notes =request.getAttribute("notes").toString();
out.println(notes);
%>
upto here ok....when i am edittng that notes in jsp as below:--
<tr>
<td>NOTES</td>
<td>: <html:textarea rows="6"
cols="30"name="searchPrfForm" property="fprofilevo.notes"
styleId="notes"/></td>
</tr>
here also showing correct ,..but when i was click submit button..it was
showing error as unterminated string constant error..
on svae function:---
var notes=document.getElementById("notes").value;
notes = notes.replace(/\n\r?/g, '<BR/>');
plz tell me ..where i have to modify it?

Uhhhmmm, I admit I just scanned the first part of this e-mail, but is
the Lucene users list an appropriate venue for this?
