JavaScript: Passing parameters to a page

Passing parameters to a page

JavaScript FAQ | Navigation Enhancements

Question: Can I pass parameters (data values) from one my page to another?

Answer: Yes, you can pass a parameter to another page in several different ways:

by storing the parameter in a cookie
by storing the parameter in a JavaScript variable of another window or frame
by storing the parameter in the rewritable property top.name (the browser window name)
by appending the parameter to the destination page's URL as a query string

Here is a simple demo illustrating all these methods for passing parameters. The value to be passed is the string 'It_worked'. When you click on the button below, the onClick JavaScript event handler is invoked. It stores the parameter (1) in a cookie named parm_value, (2) in a top-level variable top.parm_value, and (3) in the top.name property. Then the script directs your browser to the URL parm_get.htm appended with a query string containing the URL-encoded parameter value.
