I have image background.jpg
as the background. Every 10s, how to load a new background background_n.jpg
which stays for 100ms and then back to background.jpg
and so on?
How do I make an image change in HTML? Change setTimeout(“changeImage()”, 30000); to setInterval(“changeImage()”, 30000); and remove var timerid = setInterval(changeImage, 30000); .
Set an intervall that executes every 5 seconds in a useEffect that sets the new state with a randomly picked image.
The URL of the Images will be stored in a JavaScript Array and then using JavaScript setInterval function, the Background Image of HTML DIV will be dynamically changed (swapped) every 5 seconds using jQuery. The following HTML Markup consists of an HTML DIV element.
Here is an example (that does not need jQuery to work) :
var rotate = false;
function setbackground(){
window.setTimeout( "setbackground()", 5000);
newImage = rotate ? 'url(pict1.jpg)' : 'url(pict2.jpg)';
rotate = !rotate;
document.getElementById('change').style.backgroundImage = newImage;
}
function change_background( new_image_source ) {
var myimage = $( '#myimage' );
myimage.attr( 'src', new_image_source );
setTimeout( function () {
change_background( 'new image source here' );
}, 10000);
}
Use setInterval
and setTimeout
window.setInterval(function(){
window.setTimeout(function(){
$('div').css('background-image','url(background.jpg)');
},100);
$('div').css('background-image','url(background_n.jpg)');
},10000);
example: http://jsfiddle.net/niklasvh/M56A6/
You can use setTimeout(function, timeout)
(plain Javascript function) to set a function
(which you can define) to run after timeout
milliseconds
For example (the alert will be displayed after 10 seconds):
setTimeout(function () {
alert('I am running!');
}, 10000);
You can change an element's background with:
$(element).css('background-image', 'url(xy.jpg)')
Make sure you preload you background images before using them.
I'd advise against using setInterval()
for this (for such small intervals, it could stack up), use a chain of setTimeout()
s to set up the repeating action.
