check if page is already opened and Send parameter to it

Go To


How can I check if an page is already opened, and if it is, send a parameter and not open it again, and if it isn't opened, open it and send the parameter as usual.. What I want to do is: I have an page which execute a specific functionality and has status line to show to the user, I want to display the status line in another page (let's call it 'statuspage'), but because the status is changed many times I don't want to open the statusPage again and again.

How can I implement Thanks.

the downvote is not mine; do you have some code that you have tried or you want someone here to point you in the right big-picture-type direction - cctan 2012-04-04 07:32

One way could be to open the new status window using a custom name. Any subsequently windows opening calls should refresh the already created window.
