Javascript Question
Javascript slider loop
I have been trying to create an image slider for html by changing the value of the image element, using a loop to go through each image and then returning to the original image.
However once it reaches the end of the loop it doesn't continue.
Here is my Js code:
window.onload = function() {
var x = 0
while(x<1000){
setTimeout(function() {
document.getElementById('carousel').src='img/header2.jpg';
setTimeout(function() {
document.getElementById('carousel').src='img/header3.jpg';
setTimeout(function() {
document.getElementById('carousel').src='img/header.jpg';
}, 5000);
}, 5000);
}, 5000);
x = x+1
}
}

I'd recommend you to not do while loop in this case. Just recall setTimeout when executed.
window.onload = function() {
/* Element */
var carousel = document.getElementById('carousel'),
/* Carousel current image */
cimage = 2,
/* Carousel source images */
csources = [
'img/header2.jpg',
'img/header3.jpg',
'img/header.jpg'
];
function changeCarouselImage() {
// Reset the current image if it's ultrapassing the length - 1
if(cimage >= 3) cimage = 0;
// Change the source image
carousel.src = csources[cimage ++];
// Re-call the function after 5s
setTimeout(changeCarouselImage, 5000);
}
setTimeout(changeCarouselImage, 5000);
};
