oPopup = window.createPopup()

You reveal the popup window by the show() method. Here is an example of a popup window:

<SCRIPT LANGUAGE="JavaScript">
<!--
oPopup = window.createPopup();
var oPopupBody = oPopup.document.body;
oPopupBody.style.backgroundColor = "magenta";
oPopupBody.style.border = "solid blue 3px";
oPopupBody.innerHTML = "Click outside <B>popup</B> to close.";
oPopup.show(300, 80, 200, 50, document.body);
// -->
</SCRIPT>

You can find out the popup content object by calling:

oPopup.document;

One way to display the document object content is by printing its body.innerHTML property. Clicking the button below does just that. Its definition is as follows:

<FORM>
<INPUT TYPE="button" VALUE="Show Popup Document" onclick="alert(oPopup.document.body.innerHTML)">
</FORM>
