javascript - How to change the css attribute of #header using jQuery and an array of images? -

-

i trying edit script changes images of div shown below, change background-image property of #header.

as can see in fiddle here, http://jsfiddle.net/hskpq/460/ trying show images $('#header').css('background-image',..................).fadeto('slow',1);

how can this? guess have change other parts too..

var img = 0; var imgs = [     'http://www.istockphoto.com/file_thumbview_approve/9958532/2/istockphoto_9958532-sun-and-clouds.jpg',     'http://www.istockphoto.com/file_thumbview_approve/4629609/2/istockphoto_4629609-green-field.jpg',     'http://www.istockphoto.com/file_thumbview_approve/9712604/2/istockphoto_9712604-spring-sunset.jpg' ]; // preload images $.each(imgs,function(i,e){var i=new image();i.src=e;});  // populate image first entry $('img').attr('src',imgs[0]);   var opacity = 0.1; // change minimum opacity function changebg() {     $('img').fadeto('slow',opacity,function(){         $('#header').css('background-image',..................).fadeto('slow',1);     }); }    setinterval(changebg,5000);

you need couple of fixes:

  • use simple increment keep track of current image.
  • typo: "images" -> "imgs"
  • $("img") doesn't select anything, jquery fadeto "complete" callback never fired (i assume meant fade div itself)
  • you need "url('http://...')" "background-image" css property
function changebg() {     if (i >= imgs.length) i=0;     $('#header').fadeto('slow',opacity,function(){         var val = "url('" + imgs[i++] + "')";         console.log(val);         $('#header').css('background-image',val).fadeto('slow',1);     }); }

here updated demo.
