因此,我目前正在使用jQuery中的幻灯片项目,其中图像将淡入淡出。问题是这只适用于我的KhanAcademy project,而不适用于CodePen - Pen。
有人可以告诉我CodePen上的问题吗?谢谢!
代码:
var slideShow = function(container, time, effect) {
container = document.querySelector(container);
this.images = [];
this.curImage = 0;
if (effect === "fade") {
for (i = 0; i < container.childElementCount; i++) {
this.images.push(container.children[i]);
this.images[i].style.opacity = 0;
}
// Handle going to to the next slide
var nextSlide = function() {
for (var i = 0; i < this.images.length; i++) {
if (i != this.curImage) this.images[i].style.opacity = 0;
}
this.images[this.curImage].style.opacity = 1;
this.curImage++;
if (this.curImage >= this.images.length) {
this.curImage = 0;
}
window.setTimeout(nextSlide.bind(document.getElementById(this)), time);
};
nextSlide.call(this);
} else if (effect === "clickFade") {
for (i = 0; i < container.childElementCount; i++) {
this.images.push(container.children[i]);
this.images[i].style.opacity = 0;
}
// Handle going to to the next slide
var nextSlideClick = function() {
for (var i = 0; i < this.images.length; i++) {
if (i != this.curImage) this.images[i].style.opacity = 0;
}
this.images[this.curImage].style.opacity = 1;
this.curImage++;
if (this.curImage >= this.images.length) {
this.curImage = 0;
}
window.setTimeout(nextSlideClick.bind(document.getElementById(this)), time);
};
nextSlideClick.call(this);
}
};
slideShow(".slideshow", 2000, "fade");

答案 0 :(得分:2)
如果您使用the validator检查您的CSS,则会收到此错误:
0.5 is not a transition value : opacity 0.5 s
您可以看到0.5
和s
之间有空格
删除此空格,它将按预期工作。
var slideShow = function(container, time, effect) {
container = document.querySelector(container);
this.images = [];
this.curImage = 0;
if (effect === "fade") {
for (i = 0; i < container.childElementCount; i++) {
this.images.push(container.children[i]);
this.images[i].style.opacity = 0;
}
// Handle going to to the next slide
var nextSlide = function() {
for (var i = 0; i < this.images.length; i++) {
