Hai friends i want to know how to dispaly same value and different page without enter any value because already some content is there display that content in different page using javascript

Eh, what does that even mean? Can you rephrase and post some code please?

Give an example. What you are asking is not clear.

It depends on how you render your page. Is your page a static HTML? Or is it rendered via the backend (i.e. PHP, JSP, ASP, etc.). If it is a simple static HTML, you need to place cookies in your client's in order to pass the values for display in different pages. If it is rendered via back end, you simply pass the values to the server (back-end), store them in variables, and render the page using the variables.
