jQuery - 当 div 成为水平滑块上的当前容器时,div 内的动画内容
设置 我有一个全屏水平滑块,包含 5 个以上的 div,当您单击锚链接时,该滑块会向左移动。我有一些 jquery 的基本知识,并尝试使用 (scrollLeft)。但 div 是包装 div 隐藏在流中并且不会真正去任何地方。
目标是在容器 div 成为当前容器时对容器内的内容进行动画处理,并在它对不同的 div 进行动画处理时撤消动画。
问题:我可以播放动画,但无法控制它何时开始。
HTML
<div class="contentItem" id="content2">
<div id="top-box"></div>
<div id="bottom-box"></div>
</div>
<div class="contentItem" id="content3"></div>
<div class="contentItem" id="content4"></div>
<div class="contentItem" id="content5"></div>
JavaScript
var theWidth;
var theHeight;
var currentContent = 0;
$(window).resize(function () {
sizeContent();
});
$(window).ready(function () {
sizeContent();
});
function sizeContent() {
theWidth = $(window).width();
theHeight = $(window).height();
sizeContentItems();
setLeftOnContentItems();
sizeContentWrapper(theWidth, theHeight);
moveContent(currentContent, theWidth);
changeSelected(currentContent);
}
function sizeContentItems() {
$(".contentItem").css('width', theWidth);
$(".contentItem").css('height', theHeight);
}
function setLeftOnContentItems() {
var contentCount = 0;
$(".contentItem").each(function (i) {
contentCount += i;
$(this).css('left', i * 990); //slider contern hight
});
}
function sizeContentWrapper(width, height) {
$("#contentWrapper").css('width', width);
$("#contentWrapper").css('height', height);
}
function moveContent(i, width) {
$("#contentWrapper").scrollLeft(i * width);
}
function changeSelected(i) {
$(".selected").removeClass("selected");
$("li:eq(" + i + ") a").addClass("selected");
}
function scrollContentNext() {
scrollContent(currentContent + 1);
}
function scrollContent(i) {
i = checkMax(i);
scrollLogo(i);
scrollTriangle(i);
changeSelected(i)
currentContent = i;
$("#contentWrapper").animate({ scrollLeft: i * 990 }, 400); // how far to go
}
function scrollLogo(i) {
var left = (i * +200);
$("#logo").animate({ left: left }, 1000);
}
function scrollTriangle(i) {
var left = (i * -300);
$("#triangle").animate({ left: left }, 700);
}
// **my edit**
function scrollbox(i) {
var i = currentContent;
if ( currentContent = 2) {
$("#bottom-box").stop().animate({'margin-top': '200px'}, 1500);
}
}
function checkMax(i) {
var maxItems = $("li").length;
if (i >= maxItems) {
return 0;
}
return i;
}
The Setup I have a full screen horizontal slider with 5+ divs that moves to the left when you click on an anchor link. I have some basic knowledge of jquery, and did attempted to use (scrollLeft). But the div is the wrapper div is hiding over flow and doesn't really go anywhere.
The goal is to animate the content inside the container div when it becomes the current container, and undo animation when it does to a different div.
The Issue: I got the animation to play, but have no control over when it starts.
The HTML
<div class="contentItem" id="content2">
<div id="top-box"></div>
<div id="bottom-box"></div>
</div>
<div class="contentItem" id="content3"></div>
<div class="contentItem" id="content4"></div>
<div class="contentItem" id="content5"></div>
The javascript
var theWidth;
var theHeight;
var currentContent = 0;
$(window).resize(function () {
sizeContent();
});
$(window).ready(function () {
sizeContent();
});
function sizeContent() {
theWidth = $(window).width();
theHeight = $(window).height();
sizeContentItems();
setLeftOnContentItems();
sizeContentWrapper(theWidth, theHeight);
moveContent(currentContent, theWidth);
changeSelected(currentContent);
}
function sizeContentItems() {
$(".contentItem").css('width', theWidth);
$(".contentItem").css('height', theHeight);
}
function setLeftOnContentItems() {
var contentCount = 0;
$(".contentItem").each(function (i) {
contentCount += i;
$(this).css('left', i * 990); //slider contern hight
});
}
function sizeContentWrapper(width, height) {
$("#contentWrapper").css('width', width);
$("#contentWrapper").css('height', height);
}
function moveContent(i, width) {
$("#contentWrapper").scrollLeft(i * width);
}
function changeSelected(i) {
$(".selected").removeClass("selected");
$("li:eq(" + i + ") a").addClass("selected");
}
function scrollContentNext() {
scrollContent(currentContent + 1);
}
function scrollContent(i) {
i = checkMax(i);
scrollLogo(i);
scrollTriangle(i);
changeSelected(i)
currentContent = i;
$("#contentWrapper").animate({ scrollLeft: i * 990 }, 400); // how far to go
}
function scrollLogo(i) {
var left = (i * +200);
$("#logo").animate({ left: left }, 1000);
}
function scrollTriangle(i) {
var left = (i * -300);
$("#triangle").animate({ left: left }, 700);
}
// **my edit**
function scrollbox(i) {
var i = currentContent;
if ( currentContent = 2) {
$("#bottom-box").stop().animate({'margin-top': '200px'}, 1500);
}
}
function checkMax(i) {
var maxItems = $("li").length;
if (i >= maxItems) {
return 0;
}
return i;
}
