Example
Use The Evaluator (Chapter 13 in the JavaScript Bible) to experiment with the
popup object and its properties. Enter the following statements into the top text
box. The first statement creates a pop-up window, whose reference is assigned to
the a global variable. Next, a reference to the body of the pop-up’s document is preserved
in the b variable for the sake of convenience. Further statements work with
these two variables.
a = window.createPopup()
b = a.document.body
b.style.border = “solid 2px black”
b.style.padding = “5px”
b.innerHTML = “Here is some text in a popup window”
a.show(200,100, 200, 50, document.body)
See the description of the show() method for details on the parameters.

Example
Use The Evaluator (Chapter 13 in the JavaScript Bible) to experiment with the
isOpen property. Enter the following statements into the top text box. The
sequence begins with a creation of a simple pop-up window, whose reference is
assigned to the a global variable. Note that the final statement is actually two statements,
which are designed so that the second statement executes while the pop-up
window is still open.
a = window.createPopup()
a.document.body.innerHTML = “Here is a popup window”
a.show(200,100, 200, 50, document.body); alert(“Popup is open:” + a.isOpen)
