How to pass a value from one window to another window

[hungnguyen]

Hi all,

I have a question. I have a webpage containing 3 pages: main page, contents pages, and header page. In the contents page, there are buttons; in the main page, there is a form to filled out. My problem is here: I open the form and enter information and there is a field in the form needs to be calulate in specific way. Therefore, I create a button to pop a new window for calculation. I do the calculation then press the button <Total> in the window to get back to the form. However, those information I entered has been cleared. Is there any way to prevent it??
Thanks for your help.
bye

Instead of poping up a new window you should submit your form with a different action. How could you do that? Using JavaScript. When you press the button it should run a JavaScript script that change the action and submit the form.
Then in calculation windows you should set all submitted variables as hidden inputs. Now this form must call the previous window and all data is saved (you have access to all information filled previously).
This is the algorithm if you need code call me back.
