Example 15.12:
Clearing the Web Page Before Writing to a Window


Click on these buttons to open a window, then to write HTML to it. You'll notice this time that the original Web document is cleared before the new text is written:

Note that this script uses the focus() method to bring the secondary window back again. This is a JavaScript 1.1 feature, so you'll need Navigator 3 or later; with an earlier browser you'll have to switch to the window manually the second time you write to it.

Click here to close the other window:


This is the script we used. In the HEAD... <SCRIPT LANGUAGE="JAVASCRIPT"> <!-- function OpenWindow() { Win1 = open("window.htm","SecWin","scrollbars=yes,width=400,height=230"); } function CloseWindow() { Win1.close() } function MoreText() { Win1.document.write("<P>Here's some <P>more text for you...and some more. Yes, and more, and yet more<BR>") Win1.focus() } //--> </SCRIPT> Then these buttons... <FORM> <input type="button" value="Open Window" onclick="OpenWindow()"> <input type="button" value="Write to Window Again" onclick="MoreText()"><P> <I>Click here to close the other window:</I><P> <input type="button" value="Close Window" onclick="CloseWindow()"> </FORM>
