Opening closing & Passing data from Child window to parent window in JavaScript & refreshing main

Here we can control the status bar, tool bar and resize the child window from the main window. By changing the value of status to 1 form 0 (status=1;) we can display the status bar for the child window. Same way by making the toolbar=1; we can display the tool bars for the small window. We can change the value of left to position the window horizontally. If we make the value of left to 0 like left=0; to align the window to left edge of the screen. Same way by making the top=0; we can place the window at the top of the screen. Don't forget to refresh the parent window every time you change the parameters.

Here is the code at the parent window to display the link. Click the demo link to see how the window opens.
