How to stop interpolation of Escape character in variable?

[\Rob\]

I have this code.....

<script language="JavaScript">
function getLogonUser() {

var u = '<% Response.Write(
Request.ServerVariables("LOGON_USER") ) %>'
alert( u )
}
</script>

......should return "MYDOMAIN\rob.test".....but the "\r" turns into a
Carriage return

Anybody know how to prevent this from happening?

Thanks

Request.ServerVariables("LOGON_USER").Replace('\r', '') should work.

You have to use a double backslash:

MYDOMAIN\\rob.test

Otherwise the character following the "\" will be interpreted as kind of
a special instruction character. That's the reason why path names have
double backslashes in many programming languages.

Hahaha, he's right, i thought you meant \r at the end. Yea the \r in
\rob is needs to be \\rob.

It would also work if Microsoft follows the lead (over 40 years) of Unix
and use '/' instead.

Thanks, but I don't have the option to do that.....

<% Response.Write( Request.ServerVariables("LOGON_USER") ) %>

......is returning it to me.

Is this classic ASP or ASP.NET?

If it's asp.net, the do
Response.Write(Request.ServerVariables("LOGON_USER").Replace('\',
'\\'))

You could also just insert another \ at the IndexOf('\')

Double the backslash:

var u = '<% Response.Write(
Replace(Request.ServerVariables("LOGON_USER"),"\","\\") ) %>'

If it's asp.net, the do
Response.Write(Request.ServerVariables("LOGON_USER").Replace('\',
'\\'))

Not sure, if asp.net will handle single backslashes, but in JavaScript
you need to escape them:

Replace('\\', '\\\\'))

You could also just insert another \ at the IndexOf('\')

That should than be done for every "\" not only for the first one which
IndexOf('\') will probably return.
