javascript - Change background-image using jQuery addClass -


is possible change css background using jquery addclass? using following code stays on initial background image.

html

<div id="background"> </div>

jquery

$(document).ready(function() {                 (var x = 10; x > 0; x--) {                     $"#background").addclass(background2).delay(2000);                     $("#background").removeclass("background2");                     $("#background").addclass("background3").delay(2000);                     $("#background").removeclass("background3").delay(2000);                 };             });;

css

#background {     width: 100%;     height: 100%;     font-size: 1.5em;     background-image: url(backgroundimage1.jpg);     background-position: left;     background-size: cover;     background-repeat: no-repeat;     background-attachment: scroll; }  .background1 {     background-image: url(backgroundimage1.jpg); }  .background2 {     background-image: url(backgroundimage2.jpg); }  .background3 {     background-image: url(backgroundimage3.jpg); }

you have 2 issues here. firstly you're adding classes , instantly removing them delay not have effect on css() method. achieve require use setinterval instead. secondly, need increase specificity of backgroundx classes override default styles on #background element. try this:

var count = 0; var classes = [ 'background1', 'background2', 'background3' ];  function updatebackground() {     $('#background').removeclass(classes.join(' ')).addclass(classes[count % classes.length]);     count++; }  setinterval(updatebackground, 2000); 
#background.background1 {     background-image: url(backgroundimage1.jpg); }  #background.background2 {     background-image: url(backgroundimage2.jpg); }  #background.background3 {     height: 20%;     background-image: url(backgroundimage3.jpg); }

working example

note example using background-color principle same.

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
