Line breaks in string containing Javascript

[Travis Pupkin]

Hi,

I'm putting together a site to allow someone to add content to a DB
through a text area form, and then display it on the web. Pretty basic.

The problem I'm having is that they need to add snippets of javascript,
but by the time its displayed on the page, there have been extra
linebreaks added, breaking the javascript code.

Replace(string, vbCrLf,"") won't work because that removes all
linebreaks. Is there a way to preserve the original linebreaks as
submitted to the DB in the first place?

Thanks.

Just thinking off the top of my head, you could include another textarea
control for them to add the javascript, and then when you get _that_
field, you can do the replace.

Or, you could look for the beginning and end of the script tags, and
replace within them.

The text area should send the linebreaks that are entered.

Show your database update code and the code you use to send the content back
to the client.

one way - set the "wrap" attribute of the textarea to "hard" and it
sends the data exactly as it appears in the textarea.
<textarea wrap="hard" name="codeStuff">
--- or--- tell user to enter semicolons after every javascript command
** this will work**
document.write("hello"); var myVar = 10; document.write(myVar)
**this will not work***
document.write("hello") var myVar=10 document.write(myVar) //'**(no
semicolons)
**this will work** (should include some line breaks)****
document.write(
"hello"
);

Thanks for the tips. I'm beginning to think that it's the code itself
that is faulty, and not the way it's being submitted by the form.
