此链接具有类似于我要实现的旋转频率我有一个基本的图像滑块。
类似此示例的东西
jQuery(document).ready(function ($) {
$('#checkbox').change(function(){
setInterval(function () {
moveRight();
}, 3000);
});
var slideCount = $('#slider ul li').length;
var slideWidth = $('#slider ul li').width();
var slideHeight = $('#slider ul li').height();
var sliderUlWidth = slideCount * slideWidth;
$('#slider').css({ width: slideWidth, height: slideHeight });
$('#slider ul').css({ width: sliderUlWidth, marginLeft: - slideWidth });
$('#slider ul li:last-child').prependTo('#slider ul');
function moveLeft() {
$('#slider ul').animate({
left: + slideWidth
}, 200, function () {
$('#slider ul li:last-child').prependTo('#slider ul');
$('#slider ul').css('left', '');
});
};
function moveRight() {
$('#slider ul').animate({
left: - slideWidth
}, 200, function () {
$('#slider ul li:first-child').appendTo('#slider ul');
$('#slider ul').css('left', '');
});
};
$('a.control_prev').click(function () {
moveLeft();
});
$('a.control_next').click(function () {

我希望滑块单击按钮/链接时打开。我是JQUERY的新手,所以我不确定是否可以使用OnClick活动。有人可以告诉我这个实施背后的基本思想吗?谢谢!
在您的HTML中放置一个按钮,并使用它在单击时显示您的slides
。还将您完整的滑块相关的HTML包裹在DIV内,并最初隐藏潜水。如下。
<button id="showSlider">Show me the slider</button>
<div id="sliderWrapper" style="display:none;">
<!--Your current HTML goes here-->
</div>
将其安装到位,现在将所有当前逻辑放入脚本中。每当我们单击按钮时,让我们调用此功能。
function SliderScripts() {
//all your current scripts goes here
}
现在将您的文档就绪功能修改为下面。
jQuery(document).ready(function($) {
$('#showSlider').on('click', function() { // button click event
SliderScripts(); // run the sliders scripts
$('#sliderWrapper').show(); / show the slider.
$(this).hide(); //hide the button
});
});
这是一个工作片段。
jQuery(document).ready(function($) {
$('#showSlider').on('click', function() {
SliderScripts();
$('#sliderWrapper').show();
$(this).hide();
});
});
function SliderScripts() {
$('#checkbox').change(function() {
setInterval(function() {
moveRight();
}, 3000);
});
var slideCount = $('#slider ul li').length;
var slideWidth = $('#slider ul li').width();
var slideHeight = $('#slider ul li').height();
var sliderUlWidth = slideCount * slideWidth;
$('#slider').css({
width: slideWidth,
height: slideHeight
});
$('#slider ul').css({
width: sliderUlWidth,
marginLeft: -slideWidth
});
$('#slider ul li:last-child').prependTo('#slider ul');
function moveLeft() {
$('#slider ul').animate({
left: +slideWidth
}, 200, function() {
$('#slider ul li:last-child').prependTo('#slider ul');
$('#slider ul').css('left', '');
});
};
function moveRight() {
$('#slider ul').animate({
left: -slideWidth
}, 200, function() {
$('#slider ul li:first-child').appendTo('#slider ul');
$('#slider ul').css('left', '');
});
};
$('a.control_prev').click(function() {
moveLeft();
});
$('a.control_next').click(function() {
moveRight();
});

在单击上添加滑块,并用CSS样式的滑块元素
element.active {
position: fixed;
top: 50px;
left: 50%;
transform: translateX(-50%);
bottom: 50px;
z-index: 9999;
}
然后,该元素将从幻灯片中弹出,您可以将任何想要的内容添加到元素的活动类中。在您的示例中,单击"幻灯片"元素
$('#slider li').on('click', function () {
$(this).toggleClass('active');
});
活动类的CSS
li.active {
position: fixed !important;
top: 50px;
left: 50%;
transform: translateX(-50%);
bottom: 50px;
}
对于简单覆盖
li.active:after {
content: '';
position: fixed;
top: -50px;
bottom: -50px;
background: rgba(0,0,0,0.75);
left: -50%;
width: 200%;
height: 200%;
}
