Use the Open method of window to implement a child page to pass values to the parent page.

Sometimes we need to pop up a sub-page to cascade the selection data and populate the selected data with the parent page.

At this point a simple way is to open a sub-page through window.open (), when the child page commits to trigger the event, in the event of the sub-page fill in the data to the parent page method is:

WINDOW.OPENER.DOCUMENT.GETELEMENTBYID ("ID of the parent page element"). Value = ' Sub-page filled in values ';
This assignment method applies only to parent-child pages that are opened through the window.open () method. Do not use for other frames.
