Hi helper,
I'm using <textarea> tag to insert a query string to use it for a database report.
It works well as long as I dont use Enter key.
Without using Enter key in the textarea I get:
String = "Select * from TableName"
Writing this string in the textarea and using EnterKey I get:
String = "Select *fromTableName"
(I pressed the Enter Key after "*" and after "from".
This query that I get doesnt allow me to create a resultset.
How can I insert spaces after pressing the Enter Key?
Please advise
Thanks
Jo

Hi,
I inserted the following routine to replace \n char with apace and it works well.
public static CharSequence removeLineTerminator(CharSequence inputStr) {
String patternStr = "\\n";
String replaceStr = " ";
Pattern pattern = Pattern.compile(patternStr);
Matcher matcher = pattern.matcher(inputStr);
return matcher.replaceAll(replaceStr);
}

Thanks any way
Jo

There may be a simpler solution. It looks like the textarea processing in the browser is simply removing newlines. Have you checked out the "wrap" options available for the textarea tag? If you haven't, you may find that one of them produces the effect you require, without extra processing.
This bulletin board "post a reply" form I'm typing into uses <textarea wrap='virtual'> for example.

Since this is a client-side issue, I'm moving this to the HTML/Javascript forum for future reference.
