我已经为div上的某些滚动实现了jQuery Custom Scroller,这非常有用。我甚至使用平滑滚动来水平滚动到某些DIV但我的问题是我想要一个Next和Previous Navigation按钮,我无法在任何地方找到它。
下面是我的HTML和jQuery。先谢谢
<div id="source-container">
<div class="container-inner">
<div class="source-item item one current" id="the-cedarburg">
<div class="source-slide-title">
<h2>the cedarburg</h2>
</div>
</div>
<div class="source-item item two" id="our-farm">
</div>
</div>
<div class="source-item item three" id="our-rooibos">
</div>
<div class="source-item item four" id="our-process">
</div>
<div class="source-item item five" id="our-innovation">

如何将“Next”和“Prev”按钮连接到插件的scrollTo方法? 从您提供的文档链接,看起来您可以滚动到给定ID的元素(要求每个元素都有一个id而不是使用元素索引滚动)由于某种原因:
var elID="#el-1";
$(".content").mCustomScrollbar("scrollTo",elID);
对于获取滚动条中的当前项目没有太多支持,因此您可能必须自己管理(通过滚动或单击下一个/上一个按钮可以更新的索引)和使用上面的方法滚动到下一个div。
我使用常规卷轴(不是插件)为此做了fiddle。这是javascript的源代码:
var currentElement = $("#wrapper > div:nth-child(2)");
var onScroll = function () {
//get the current element
var container = $("#source-container");
var wrapper = $("#wrapper");
var children = wrapper.children();
var position = 0;
for (var i = 0; i < children.length; i++) {
var child = $(children[i]);
var childLeft = container.offset().left < child.offset().left;
if (childLeft) {
currentElement = child;
console.log(currentElement)
return;
}
}
}
var indexClick = function () {
console.log($("#inputScrollIndex").val())
var index = parseInt($("#inputScrollIndex").val(), 10) - 1;
if (index < 1) {
index = 0;
}
console.log(index);
scrollToIndex(index);
}
var scrollToIndex = function (index) {
var element = $($("#wrapper").children()[index]);
scrollToElement(element);
}
var scrollToElement = function ($element) {
var container = $("#source-container");
var wrapper = $("#wrapper");
var children = wrapper.children();
var width = 0;
for (var i = 0; i < children.length; i++) {
var child = $(children[i]);
if (child.get(0) == $element.get(0)) {
if (i == 0) {
width = 0;
}
container.animate({
scrollLeft: width
}, 100);
onScroll();
}
if (child.next().length > 0) {
//make sure we factor in borders/padding/margin in height
width += child.next().offset().left - child.offset().left
} else {
width += child.width();
}
}
}
var next = function (e) {
scrollToElement(currentElement);
}
var prev = function (e) {
var container = $("#source-container");
if (currentElement.prev().length > 0) {
if (container.offset().left == currentElement.prev().offset().left) {
currentElement = currentElement.prev().prev().length > 0 ? currentElement.prev().prev() : currentElement.prev();
} else {
currentElement = currentElement.prev();
}
}
scrollToElement(currentElement);
}
$("#source-container").scroll(onScroll);
$("#scrollIndex").click(indexClick);
$("#next").click(next);
$("#prev").click(prev);
