- PopupWindow.js
- Author: Matt Kruse
- Last modified: 02/16/04
-
- DESCRIPTION: This object allows you to easily and quickly popup a window
- in a certain place. The window can either be a DIV or a separate browser
- window.
-
- COMPATIBILITY: Works with Netscape 4.x, 6.x, IE 5.x on Windows. Some small
- positioning errors - usually with Window positioning - occur on the
- Macintosh platform. Due to bugs in Netscape 4.x, populating the popup
- window with <STYLE> tags may cause errors.
-
- USAGE:
- // Create an object for a WINDOW popup
- var win = new PopupWindow();
-
- // Create an object for a DIV window using the DIV named 'mydiv'
- var win = new PopupWindow('mydiv');
-
- // Set the window to automatically hide itself when the user clicks
- // anywhere else on the page except the popup
- win.autoHide();
-
- // Show the window relative to the anchor name passed in
- win.showPopup(anchorname);
-
- // Hide the popup
- win.hidePopup();
-
- // Set the size of the popup window (only applies to WINDOW popups
- win.setSize(width,height);
-
- // Populate the contents of the popup window that will be shown. If you
- // change the contents while it is displayed, you will need to refresh()
- win.populate(string);
-
- // set the URL of the window, rather than populating its contents
- // manually
- win.setUrl("http://www.site.com/");
-
- // Refresh the contents of the popup
- win.refresh();
-
- // Specify how many pixels to the right of the anchor the popup will appear
- win.offsetX = 50;
-
- // Specify how many pixels below the anchor the popup will appear
- win.offsetY = 100;
-
- NOTES:
- 1) Requires the functions in AnchorPosition.js
-
- 2) Your anchor tag MUST contain both NAME and ID attributes which are the
- same. For example:
- <A NAME="test" ID="test"> </A>
-
- 3) There must be at least a space between <A> </A> for IE5.5 to see the
- anchor tag correctly. Do not do <A></A> with no space.
-
- 4) When a PopupWindow object is created, a handler for 'onmouseup' is
- attached to any event handler you may have already defined. Do NOT define
- an event handler for 'onmouseup' after you define a PopupWindow object or
- the autoHide() will not work correctly.
