I use opera as my main browser but find it difficult to use to do online
business since its javascript often crashes or just hangs on some sites. I
don't always know if I just have opera misconfigured or if opera's
javascript implementation is bad.
I have come to the conclusion that javascript as implemented in many linux
browsers just isn't very good, or, is simply not compatible with with many
web pages.
As an example, look at this very simple web page on my home computer,
HammersHome.com
This will hang opera, so be careful!
This page was made with WebSphere, the IBM free web page maker. Quite nice.
The image has two events associated with it. onClick, a message box pops up.
onMouseover a second message box pops up. Each of my browsers behaves
differently with it:
Opera works well with onClick, but with Mouseover, the message box never goes
away and you lose control of the browser.
Netscape 6.0 functions as you would expect.
Netscape 4.75, even with javascript enabled, ignores the events, in both
windows and linux. Looking at the page source shows that the event handlers
aren't even loaded.
Internet explorer under win4lin or windows works almost as expected but you can't
close the
window because the message box just keeps popping up when you hit close.
Mozilla, version 1.9, works as expected.
SO, the conclusion is, javascript is still a jungle, it is not fully standardized,
and we in the linux world cannot expect web page designers to worry about
us, since we are an insignificant part of the market. I have yet to see a
web page (I don't look that hard) which as opera specific code in it, for
example.
I hope the mozilla/linux_netscape people are listening and make their
javascript compatible with whatever $MS decides to do, because that will be
the standard.
