Java, JavaScript and VBScript

I've become interested in controlling HTML pages. This interest is mainly for work, in order to be able to link to some of our existing databases, with a nice new front end.

I rapidly discovered that Java is two languages, one imbedded in HTML pages called JavaScript and another which can be run standalone or called as a separate class file from within HTML pages, usually called Java Applets.

I found the implementation of JavaScript on Internet Explorer 3.02 a little frustrating as all the documentation refers to Netscapes implementation, so I tried VBScript instead.

Java Applets - Here are a few sites of interest so far

• Bill Gercken's Java Page - some examples and Links to other Java sites
• Java Developers Connection - Sun's own Java developers site
• Javasoft Homepage - Sun's Java homepage, lots of good info on this site
• Java Tutorial - this is from the Javasoft pages and can be downloaded
Scripting Tips for Internet Explorer 3.02

1. If you have relative path names within your script do not use null documents for your frames. Use a blank html document to fix the start location for the path.
JavaScript
Having tried JavaScript on Internet Explorer 3.02 I was a little frustrated and dissapointed, but I now have some ideas of what works and what doesn't!

JavaScript Tips for Internet Explorer 3.02

1. Use frames not Windows. There are lots of window commands that open up another sheet to use within the script. These do not work reliably on line although, to my frustration, they worked off line!

VBScript - I looked at this because of my disappointment with JavaScript.

1. Variables are not passed across windows. Use frames to use global variables.
