String with carriage returns causes problems

I am trying to display a String by default into a text area using a JSP directive and it works unless there is a carriage return contained in the String that is returned.

What I am looking for is what character will represent the carriage return to do a substring and break it up into multiple javascript assignments.

For instance:

Now there is:

document.getElementById('coverRow2').innerHTML = "<textarea cols='40' rows='10' name='coverPageContent' id='coverPageContent' onKeyUp='setScreenState(true); wrap'><%=faxCoverBLOB.getCompressedBlobString() %></textarea>";

I think I would need to go with
javascriptString += substring(faxCoverBLOB.getCompressedBlobString(), 0, indexOf('character')) or something like that, but I don't know which character I should search for.

you will also have problems with quotes("):-
faxCoverBLOB.getCompressedBlobString().relpace("\n","\\n").relpace("\"","\\"");

actually
faxCoverBLOB.getCompressedBlobString().relpaceAll("\n","\\n").relpaceAll("\"","\\"");

That's a great idea, but it didn't work. Also my IDE won't compile the page with the replaceAll("\"", "\\"") portion. I still get an unterminated string constant with this.

Well, I had to bite the bullet and include the textarea in the main source of the html. Does anyone have a good way of handling an unchecked checkbox submit?

if you have a boolean value for your checkbox:-
<% boolean chkBoxVal=(request.getParameter("chkBoxParam")!=null)?true:false;%>

Actually, I figured it out already, but gave you the answer. I have a javascript method that actually does the submitting and I can pass additional request paramaters to it and have used that.

Thanks anyhow. The replaceAll function may come in handy later.
