Troubleshooting JavaScript/JScript

4. Why won't my script work ...

1. ... inside a table?

   There is a long-standing bug in JavaScript concerning tables. To be safe, Do not place <SCRIPT> tags inside <TD> tags. Instead, start the <SCRIPT> tag before the <TD> tag, and document.write() the <TD> tag through the </TD> tag. If you're a belt-and-suspenders kind of guy, you can go a step further by using document.write() to create the entire table , interlacing script statements where needed.

2. ... under MS Internet Explorer 3 for the Mac?

   JScript is available on the Macintosh starting with 3.0.1 (which is different from the Windows 3.01). I am still evaluating the Mac implementation, whose object model and other support for JavaScript does not necessarily jive with the Windows v ersion (e.g., the Mac version supports the Image object for mouse rollovers). MSIE 3.0.1 runs on Mac 68K and PPC. Download it from: http://www.microsoft.com/msdownload/ieplatform/iemac.ht m

3. ... under MSIE 3 for Windows 95?

   Most language features and objects that are new in Navigator 3.0 are not supported in MSIE 3.0, although several Navigator 3.0 items have been added to JScript version 2 (see below).

4. ... when I use document.cookie with MSIE?

   It does work, but not when you access the HTML file from your local hard disk, as you are probably doing during testing. Be aware, however, that MSIE limits you to one cookie name=value pair per domain, whereas Netscape allows up to 20 pairs per domain.
