Closing a browser window

If you use multiple windows in your Domino application, you may want to close one of them programmatically.

In your form's JS Header, declare a variable called LotusWin:

 var LotusWin; On the form, create a button with the following JavaScript: LotusWin = window.open('http://www.lotus.com', 'LotusSite'); This opens a new window containing Lotus' web site. The name of the window is 'LotusSite'. The variable LotusWin now contains a pointer to this window. To close the window, you would think you could use: LotusWin.close(); ...but this doesn't work. Why? Because the Lotus web site contains frames. To force the closure of the browser window, you have to use: LotusWin.top.close(); This forces the close to happen at the top-level object of the LotusWin window -- the browser window itself rather than any frames.

 In form JS Header: var LotusWin; In button labeled 'Open': LotusWin = window.open('http://www.lotus.com', 'LotusSite'); In a button labeled 'Close': LotusWin.top.close();
