jQuery(document).ready(function(){
jQuery('div').css('background-color','#ffffff').delay(12000).css('background-color','#000000');
});
Hello everyone! I'm having some trouble with this code. I am attempting to change the background color of a div element after a certain amount of time has passed, but it doesn't seem to be working as expected.
One possible solution is to use the setTimeout method.
jQuery(document).ready(function(){
var elements = jQuery('div').css('background','#fff');
setTimeout(function(){ elements.css('background','#000'); }, 12000);
});
Using only CSS, you have the ability to achieve this.
body {
animation:color-change 5s 1;
-webkit-animation:color-change 5s 1; /* Compatible with Safari and Chrome */
animation-fill-mode: forwards;
-webkit-animation-fill-mode: forwards;
}
@keyframes color-change
{
0% {background:#fff;}
90% {background:#fff;}
100% {background:#000;}
}
@-webkit-keyframes color-change /* Safari and Chrome */
{
0% {background:#fff;}
90% {background:#fff;}
100% {background:#000;}
}
To customize the animation effects, simply adjust the properties as needed.
When it comes to using .delay(), keep in mind that it only functions with jQuery's standard effect queue or a custom one. In most cases, opting for a setTimeout() call would be more suitable.
jQuery(document).ready(function(){
jQuery('div').css('background','#fff')
setTimeout( function(){ jQuery('div').css('background','#000'); }, 12000);
});
Take a look at this jsFiddle example (with a three-second timeout for quicker display)
When using the jQuery delay function, it is important to queue subsequent functions in order for them to execute properly:
$('div').css('background','#fff').delay(12000).queue(function(nxt){
$(this).css('background','#000');
nxt(); // continue the queue
});
