Note Chapter 4 ✦ The Document and Body Objects (Chapter 18) drawPage(“default”) To satisfy the curiosity of those who want to change the color of a loaded document on the fly, the preceding example includes a pair of buttons that set the color properties of the current document. If you’re running browsers and versions capable of this power (see Table 18-1), everything will look fine; but in other platforms or earlier versions, you may lose the buttons and other document content behind the color. You can still click and activate these items, but the color obscures them. Unless you know for sure that users of your Web page use only browsers and clients empowered for background color changes, do not change colors by setting properties of an existing document. anchors If you are using Internet Explorer 3 for the Macintosh, you will experience some difficulties with Listing 18-1. The script in the main document loses its connection with the subwindow; it does not redraw the second window with other colors. You can, however, change the colors in the main document. The significant flicker you may experience is related to the way the Mac version redraws content after changing colors. NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Compatibility ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ Example In Listing 18-2, I append an extra script to Listing 17-1 (in Chapter 3 of this book) to demonstrate how to extract the number of anchors in the document. The document dynamically writes the number of anchors found in the document. You will not likely ever need to reveal such information to users of your page, and the document.anchors property is not one that you will call frequently. The object model defines it automatically as a document property while defining actual anchor objects. 227 document.anchors
