appName and versions

[richard_r]

When a person loads my page, I would like to know if their application and version would be able to effect how certain scripts work.

functions, alerts, and passwords..?

Easiest way is to test it in diff versions. Post a link and ask people to try iy out.

I know that there is a script available to detect the surfer's (person who visits my site) browser, screen size, resolution, and so on and so forth..

Does anybody know of a website that has a comprehensive website of JavaScript Versions against Browsers and that support specific versions of JS?

for the screen size you have screen.width and screen.height and for the navigator, well you have an entire bject so try to find yourself a hierarchy sheet with all the different obejcts and methods of javascript
