working with time?

[Bad_Kid]

how to set javascript to start every x ms?? [setTimeout('nam e()', speed)] ??
- and how to start that same javascript (second instance) with delay - for
example ->
javascript colors specified text to red and back to black every x ms...
how to start that same javascript on another text, with slight delay? (so it
goes: 1st text goes red, __ , 2nd text goes red, ___ 1st text goes black,
___ 2nd text goes black,___ ???

if those 5 lines work,
element.style.c olor ^= 0xFF0000
should work
[color=blue]
>}[/color]

However, since the colour is being changed in a preordained sequence, it
should be simpler to use
X %= n ; element.style.c olor = [0x000000, 0xFF0000, ...][X++] ;
where the literal array has n elements and X is declared outside the
function changeText. That may well remove the need for feature
detection.


Code should be indented to show logical structure - see FAQ/notes.

Unlikely. The value of element.style.c olor is a string.
You don't know the format returned, althoug it is likely to be
#xxxxxx. Converted to a number, that is NaN, and xor'in it with
0xFF0000 will not change that ... and if it did, the result would
be a number, not a CSS color value.
