I have a pop up window that has a form when the user submits the form on the pop up window it should close and refresh the parent page.

i have used
1.

Code:

<input type="submit" value="Submit" />

->which closes the popup window without submitting the form

2.

Code:

<input type="submit" value=submit" />

->which submits the form but the popup window becomes blank; "it turns white"
