Determine if a window was opened window.showModalDialog?

Question

Does anyone know how to find out if window.showModalDialog() opened? window.opener returns the parent window when window.open() opens, but for some reason, when you use window.showModalDialog() , window.opener returns as undefined. JQuery solutions are also welcome.

Answer 1

You can check if window.dialogArguments is defined :

 function isModalWindow() { return (window.dialogArguments != null); }
