how to Change image automatically in every specified seconds by JavaScript


<script>
var image=['image-1.jpg','image-2.jpg','image-3.jpg'];
var i=0;
function AutoChangeImage(){
document.getElementById('image').src=image[i];
i++;
var d;
for(d=0;d<=2000;d++){
//delay
}

AutoChangeImage();
}

</script>
<img src='image.jpg'  id="image"/>

if you see above code , i made function AutoChangeImage() to change image but i need it should be change image after 2 second and i used for loop to delay it for 2 second

for(d=0;d<=2000;d++){
//delay
}

i am thinking each iteration take one millisecond .
i do not think its good way to use for loop to delay it .not good at JavaScript so suggest something more better

yes it is not good to use loop like for or while to make delay in script .

for the delay JavaScript Native have function setTimeout

setTimeout(func , 2000) means run func function after 2 second (2000 milisecond )

so in your case wait for page load complete. window.load is the function will used for it


window.onload=function(){
    setTimeout(function(){
AutoChangeImage();
    }, 2000);
};
