来自＃个孩子的CSS动画延迟

Question

I'm trying to write a java script that offsets the start and loop delays of CSS animations. the offset should be based off of the number of images in the containing div. I'm not very experienced with javascript so any help would be appreciated.

JavaScript:

function bannersImgOffset(){

var photoBanners = document.getElementsByClassName("photoBanner");
for(var i=0; i < photoBanners.length; i++){

    var bannerChildren = i.getChildNodes;
    var loopDelay = bannerChildren.length*5;

    for(i=0, i>bannerChildren.length, i++){
        var imageDelay = (i*5); 

        i.style.webkitanimation = "bannerCycle 5s linear infinite " + loopDelay + "s";
        i.style.mozanimation = "bannerCycle 5s linear infinite " + loopDelay + "s";
        i.style.msanimation = "bannerCycle 5s linear infinite " + loopDelay + "s";
        i.style.oanimation = "bannerCycle 5s linear infinite " + loopDelay + "s";
        i.style.animation = "bannerCycle 5s linear infinite " + loopDelay + "s";

        i.style.webkitanimationDelay = imageDelay + "s";
        i.style.mozanimationDelay = imageDelay + "s";
        i.style.msanimationDelay = imageDelay + "s";
        i.style.oanimationDelay = imageDelay + "s";
        i.style.animationDelay = imageDelay + "s";
        }
    }
}

html:

    <div class="photoBanner">
        <img src="Image01.jpg" alt="">
        <img src="Image02.jpg" alt="">
        <img src="Image03.jpg" alt="">
        <img src="Image04.jpg" alt="">
        <img src="Image05.jpg" alt="">
    </div>

Thanks in advance.

Did you intend to use the same variable to set your second level for loop? If not, try using a different variable inside the 2nd level for loop.
