Controlling Text; Targeting Links; 'Webbots'
By David Fiedler and Scott Clark
Dear Dr. Website: Can I control the appearance of text (font, size, background color) in form fields, or am I stuck with browser settings?You might use standard FONT tags within a form, changing the text color, size, face, etc. As for background colors, you could use a table within the form, and then use background colors or even images within the table.
Dear Dr. Website: I've seen Java scripts for creating a pop-down list with links for navigation, and I've seen a frame-based example on the Web. But I want a way to use different targets for my links in the same form.
We love it when we've already got a question figured out, and the code is sitting right on our home page, too! Here's your solution:
<HEAD> <SCRIPT LANGUAGE=JavaScript> <!-- function doArray() { var arylnth = doArray.arguments.length; for ( i = 0 ; i < arylnth ; i++ ) { this[i]=doArray.arguments[i] } } function newpage() { var choose = eval(document.dropdown.site.selectedIndex); if( (choose > 0) && (choose < 12) ) { var section=new doArray( ' ', 'http://www.webdeveloper.com/index.html', 'http://www.webdeveloper.com/library/', 'http://www.webdeveloper.com/library/reference.html', 'http://www.internetnews.com/wd-news/', 'http://www.webdeveloper.com/reviews/', 'http://www.webdeveloper.com/devforum/'); top.left.location=section[document.dropdown.site.selectedIndex]; } } //--> </SCRIPT> </HEAD> <BODY> <FORM NAME="dropdown"> <SELECT NAME="site" onChange='newpage();' ALIGN="left"> <OPTION SELECTED>Select a Web Developer Section <OPTION>Main page <OPTION>DoIt Library <OPTION>Reference <OPTION>Web Developer News <OPTION>Reviews <OPTION>Developer's Forum </SELECT> </FORM> </BODY>The important part is:
top.left.location=section[document.dropdown.site.selectedIndex];This part tells the browser where to open the page; "top" tells the browser that the frame to be updated is the main frameset; and "left" is the name of the frame to be updated.
Dear Dr. Website: My FrontPage 98-generated guest book doesn't update properly. Can you help? Here is the code:
<p><!--webbot bot="PurpleText" Preview="Guest Book - Use this page to collect the reactions of visitors to your web site." --> </p> </body> </html>
Does your Web host/ISP support FrontPage extensions? The FrontPage tool uses "webbots"--basically server-side processes--and your guest book is one such example. Without the FrontPage extensions, the process never happens, and the guest book won't update.
