It's calling the function right away rather than after a delay. The
braces are incorrect (though syntactically valid). When that line
runs, the function is called immediately, and then I _think_ the
result is thrown away and undefined is passed into setTimeout; either
that, or the function's result is passed into setTimeout, but I'm
pretty sure not. Again, you just don't do that, so I'm not sure of
the effect of the braces. I am sure the function is executed
immediately.
You wanted to write this:
xtimer = setTimeout( function(){ doSomething( arg1, arg2,
arg3 ); }, 500);
^^^^^^^^^^
Or even better, use the features[1] of the library we're all talking
about:
xtimer = doSomething.delay(0.5, arg1, arg2, arg3);
I'll second Tobie's suggestion: It's well worth your time to read up
on this stuff. Websites, blogs, wikis, good old-fashioned books,
etc. Here's[2] a list of suggested material in the unofficial FAQ.
Also, take an hour to read through the complete Prototype API[3]
(literally, that's all it takes to read through it, an hour). In a
couple of months' time, you might check out Crockford's site[4] on
JavaScript (not Prototype), but probably not right now -- he gets into
advanced topics.
