我刚刚完成了一个我正在研究的旋转木马,它使用滑动/触摸,还使用prev / next等控件来控制旋转木马。现在我有关于旋转木马行为的问题。基本上我正试图让它一个接一个地滑动。以下是我一直在研究的代码示例。现在它似乎滑动了2或3,这取决于我放置了多少个旋转木马。
我也有关于使其响应的问题

好的,我在这里的第一个答案是匆忙完成的,但我相信我有一个清晰的JavaScript表示最现代的旋转木马会起作用,尽管如果你选择使用它,其余的由你决定。
以下是解释良好的JavaScript方面
// Index all Carousel
for (var i = 0; i < document.getElementsByClassName("carousel").length; i++) {
// Create a container for all the slides
document.getElementsByClassName("carousel")[i].innerHTML = (
'<div class="slides-container">' +
document.getElementsByClassName("carousel")[i].innerHTML +
'</div>'
);
// If the Carousel is automated
if (document.getElementsByClassName("carousel")[i].getAttribute("data-auto")) {
// Remove all white-space in the Carousel's "data-auto" attribute.
document.getElementsByClassName("carousel")[i].setAttribute("data-auto", document.getElementsByClassName("carousel")[i].getAttribute("data-auto").replace(/ /g, ""));
// Set the Carousel direction
document.getElementsByClassName("carousel")[i]._direction = String(document.getElementsByClassName("carousel")[i].getAttribute("data-auto").slice(0, document.getElementsByClassName("carousel")[i].getAttribute("data-auto").indexOf("_")));
// Set the Carousel interval
document.getElementsByClassName("carousel")[i]._interval = (parseFloat(document.getElementsByClassName("carousel")[i].getAttribute("data-auto").slice(document.getElementsByClassName("carousel")[i].getAttribute("data-auto").indexOf("_")).replace("_", "")) * 1000)
};
// Index all Carousel slides
for (var j = 0; j < document.getElementsByClassName("carousel")[i].querySelector(".slides-container").children.length; j++)
// Hide them
document.getElementsByClassName("carousel")[i].querySelector(".slides-container").children[j].hidden = true;
// Show the first one or the specified slide
document.getElementsByClassName("carousel")[i].querySelector(".slides-container").children[(parseInt(document.getElementsByClassName("carousel")[i].getAttribute("data-active")) || 0)].hidden = false;
// Carousel Next
document.getElementsByClassName("carousel")[i]._next = function() {
// Index all Carousel Slides
for (var j = 0; j < this.querySelector(".slides-container").children.length; j++)
// Show the next slide in the set
if (this.querySelector(".slides-container").children[j].hidden == false) {
this.querySelector(".slides-container").children[j].hidden = true;
(this.querySelector(".slides-container").children[j].nextElementSibling || this.querySelector(".slides-container").children[0]).hidden = false;
break
}
};
// Carousel Previous
document.getElementsByClassName("carousel")[i]._prev = function() {
// Index all Carousel Slides
for (var j = 0; j < this.querySelector(".slides-container").children.length; j++)
// Show the previous slide in the set
if (this.querySelector(".slides-container").children[j].hidden == false) {
this.querySelector(".slides-container").children[j].hidden = true;
(this.querySelector(".slides-container").children[j].previousElementSibling || this.querySelector(".slides-container").children[this.querySelector(".slides-container").children.length - 1]).hidden = false;
break
}
};
// Carousel Toggle
document.getElementsByClassName("carousel")[i]._toggle = function(slideIndex) {
// Index all Carousel Slides
for (var j = 0; j < this.querySelector(".slides-container").children.length; j++)
// Hide them
this.querySelector(".slides-container").children[j].hidden = true;
// Show the specified slide
(this.querySelector(".slides-container").children[slideIndex] || document.createElement("div")).hidden = false
};
// If the Carousel Interval is a Number
if (typeof document.getElementsByClassName("carousel")[i]._interval == "number") {
// Index
var index = i;
// Set an interval to automate the Carousel
setInterval(function() {
// If the Carousel direction is right
if (document.getElementsByClassName("carousel")[index]._direction == "right")
document.getElementsByClassName("carousel")[index]._next();
// If the Carousel direction is left
else if (document.getElementsByClassName("carousel")[index]._direction == "left")
document.getElementsByClassName("carousel")[index]._prev()
}, document.getElementsByClassName("carousel")[i]._interval)
}
// If the Carousel has buttons
if (document.getElementsByClassName("carousel")[i].hasAttribute("data-buttons"))
// Make the Buttons Container
document.getElementsByClassName("carousel")[i].innerHTML += (
'<div class="buttons-container">' +
'<button onclick="this.parentNode.parentNode._prev()"> Previous </button>' +
'<button onclick="this.parentNode.parentNode._next()"> Next </button>' +
'</div>'
)
// If the Carousel has indicators
if (document.getElementsByClassName("carousel")[i].hasAttribute("data-indicators"))
// Make the Indicators Container
document.getElementsByClassName("carousel")[i].innerHTML += (
'<div class="indicators-container">' +
// Place as many checkboxes for as many slides there are
(function() {
var indicators = "";
for (var k = 0; k < document.getElementsByClassName("carousel")[i].querySelector(".slides-container").children.length; k++)
indicators += (
'<input class="indicator-' + k + '" onclick="this.parentNode.parentNode._toggle(this.getAttribute(\'class\')[this.getAttribute(\'class\').length - 1])" type="checkbox">'
);
return indicators
})() +
'</div>'
);
// Add a click event to the Carousel
document.getElementsByClassName("carousel")[i].addEventListener("click", function() {
// Index all Carousel
for (var j = 0; j < document.getElementsByClassName("carousel").length; j++)
// If the Carousel indexed is not the target Carousel
if (document.getElementsByClassName("carousel")[j] != this)
// Blur it
document.getElementsByClassName("carousel")[j].removeAttribute("data-focus");
else
// 'Focus' it
document.getElementsByClassName("carousel")[j].setAttribute("data-focus", "")
// If the mouse click is to the left of the carousel
if (event.clientX < (this.getBoundingClientRect().left + (this.getBoundingClientRect().width / 2)))
this._prev();
// If the mouse click is to the right of the carousel
else if ((event.clientX > (this.getBoundingClientRect().left + (this.getBoundingClientRect().width / 2))))
this._next()
})
};
// Attach an event to the <body>.
document.body.addEventListener("keydown", function() {
switch (event.code) {
// If the left arrow key is pressed
case "ArrowLeft":
document.querySelector(".carousel[data-focus")._prev();
break;
// If the right arrow key is pressed
case "ArrowRight":
document.querySelector(".carousel[data-focus")._next();
break;
}
})
在Carousel代码的这一部分中,.hidden
属性可以替换为其他任何内容,但它提供了幻灯片如何通过活动和非活动状态传递的基本概念。
至于HTML部分
<html>
<body>
<div class="carousel" data-active="1" data-auto="right_1" data-buttons data-indicators style="height: 300px">
<div style="background: #F00; color: #FFF; font-size: 50px; height: 100%; line-height: 300px; text-align: center"> R </div>
<div style="background: #0F0; color: #FFF; font-size: 50px; height: 100%; line-height: 300px; text-align: center"> G </div>
<div style="background: #00F; color: #FFF; font-size: 50px; height: 100%; line-height: 300px; text-align: center"> B </div>
</div>
<!-- The JS script for the Carousel -->
<script src="carousel.js"> </script>
</body>
</html>
一切都已简化:
制作新转盘的class
carousel
,
data-active
属性指出哪个幻灯片处于活动状态(从0
开始),
data-auto
属性指定轮播是否自动化(right_
代表自动化的方向,_1
代表区间的长度),
如果需要按钮,data-buttons
属性,
data-indicators
如果需要轮播指示符
幻灯片作为旋转木马的孩子。

在元素集合中设置/获取值时,最好use .map()。以下是50行(view on CodePen)中的答案:
$(".faculty-carousel").map(function() {
// Use that to refer to the child nodes of each carousel object instance
var that = $(this),
slides = that.find(".faculty-items li"),
carousel = that.find(".faculty-items"),
prevBtn = that.find(".prev"),
nextBtn = that.find(".next"),
slideLen = slides.length,
slideCount = slideLen - 1;
// Set reference point for carousel movements. The .is-active class will always
// be applied to the activeSlide, providing a reliable method for maintaining
// the carousel's state.
slides.first().addClass("is-active");
// Shift in response to user click. Accepts optional direction argument
var shiftCarousel = function(direction) {
var target = that.find(".is-active");
var currentSlide = target.attr("data-slide");
if (direction === "left" && currentSlide > 0) {
currentSlide--;
target.removeClass("is-active").prev().addClass("is-active");
}
if (direction === "right" && currentSlide < slideCount) {
currentSlide++;
target.removeClass("is-active").next().addClass("is-active");
}
var transformPercentage = -1 * currentSlide / slideLen * 100;
carousel.css("transform", "translateX(" + transformPercentage + "% )");
};
var x = 0;
// Get position of each slide and store it in an HTML attribute
slides.each(function() {
$(this).attr("data-slide", "" + x++ + "");
$(this).click(function() {
$(this).addClass("is-active").siblings().removeClass("is-active");
// Invoke shiftCarousel() without a parameter
shiftCarousel();
});
});
// Invoke shiftCarousel() with a parameter
prevBtn.on("click", function() {
shiftCarousel("left");
});
nextBtn.on("click", function() {
shiftCarousel("right");
});
// to manage mobile events, you can reference events via Hammer API
// or JavaScript's built-in touchstart, touchcancel etc. events i.e.
// prevBtn.on('touchstart', function() {
// do something
// });
});
最好坚持使用jQuery。 Oluwafunmito的解决方案使用innerHTML
,这是使用vanilla JS的唯一实用技术。但是,innerHTML
可以inadvertently expose your website visitors进行XSS攻击,应尽可能避免。

您在所有转盘上的所有幻灯片上使用.each,为每张幻灯片设置平移事件和动画。尝试仅在$('.faculty-carousel').each
