Handling 'multi-line' string variables

[neilm]

My application needs to read a field from a database that contains a multi-line
piece of text (actually a piece of html code). I want to store this string
in a client side javascript variable (want to be able to assign it to a text
box in a form). Code looks like this

<% dim sz
...
sz = rs("tmltext")
...
%>

<SCRIPT LANGUAGE="javascript">
var sz = "<% = sz %>"
...
</SCRIPT>

The expansion of <% = sz %> (obviously) causes a scripting error as it inserts
lines of html into the script. How do I get around this problem? Thanks.

It would occur to me that quite possibly you are attempting to use a
server side call from client side script
e.g.(
<SCRIPT LANGUAGE="javascript">
var sz = "<% = sz %>"
...
</SCRIPT>
)

Thats a no,no.

What you might try is generating the client side script in the .asp server
side code. (e.g. Response.write ("<SCRIPT LANGUAGE=""javascript"">") & chr(10)
& chr(13)
Response.write ("var sz =") & sz
Response.write </SCRIPT>

Or something along those lines this reply is a little rushed. But the concept
is generate the entire script tags in the .asp code and utilize the server
side variable there.

The construction is a perfectly acceptable way to transfer values from the
server to a client-side script.

There's nothing wrong with that code as long as you understand what it does.
In this case, it creates a line of client-side script that defines a string
variable. However, you also have to understand that the value of the
client-side sz variable is the value of the server-side sz variable _at the
time the page was created_, and that changing the client-side variable _does
not_ affect the value of the server-side variable. Finally, you need to
understand that the code between the <% %> tags only runs on the server. The
code doesn't dynamically connect to the server and retrieve a value--the
client-side sz variable gets its value because the server resolves the <%=
sz%> code when it creates the page.
