To escape character in javascript/jsp

I have this code bit:

var description = '${requestScope.description}';

In the above code if

${requestScope.description} = '''''''''

IE is throwing script error. How to solve this problem?

You mean to same that description itself is a consecutive quotes? — sundar, Aug 14 '12 at 09:25

Can you fix it using the technique mentioned in https://stackoverflow.com/a/1473192/476786 as suggested by @xdazz.

If not, try using double quotes as follows:

var description = "${requestScope.description}";

Edit: OP says that description could also potentially contain " (double quotes):

In that case, you could replace the double quotes before you output the string as:

var description = "${requestScope.description.replace("\"", "''")}";

This would replace all instances of double quotes with 2 single quotes.

Please note that my jsp isvery weak, and as such the code sample above might need a tweak or two... :)

@xdazz it is working for Apostrophe but if "${requestScope.description}" value is "(double quotes) it is not working again the same script error — Chinna, Aug 14 '12 at 09:50
