javascript - setTimeout() in for each loop doesn't work -


i have make board assignment lights 1 1 sci-fi movie “close encounters of third kind”. main objective here specific blocks light in specific order 2 second interval between them code have done now:

$(document).ready(function () {      var colorblocks = [         'yellow',         'green',         'blue',         'white',         'orange'     ]      $.each(colorblocks, function (i) {         $('#' + this).css("background", this);         // when use alert can see boxes change color 1 one         // alert(something);     });  });

but doesn't seem work changes colour of boxes @ once unless if alert(something);

can help?

i think want this:

$.each(colorblocks, function (i) {     settimeout(function() {         $('#' + this).css("background", this);     }.bind(this), * 2000); });

why i * 2000?

i iteration's index, it'll wait i * 2000 ms each call next "animation" occur.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
