"Is there anything wrong about the post?"
Someone suggested for you to use http://jsfiddle.net/
and you replied asking how to use Fiddler which is a different program/service.
Go to http://jsfiddle.net/
and create a page that has your code and shows the work you have done to resolve the issue.
People on forums and http://www.stackoverflow.com
help people who are helping themselves first. You just posted a problem and asked for a solution without showing what work you have already put into resolving the issue for yourself. What things have you tried to resolve this on your own?
I don't know the answer to your original question but I had some input on the last one.
