我想要做什么
*滚动时显示图片
看右边的移动句子。
就像这样,我想每次滚动时突出显示<p>
元素。
也就是说,通常它的opacity: 0.3;
,当它滚动时,从顶部逐个切换到opacity: 1;
。
我认为我可以使用swiper.js来实现这一点。
我现在感觉是这样的,请也看看右侧的那个。
如果此滑块包装达到每个<p>
的高度并停止滚动使用preventDefault()
, 我认为实现会如预期。
我尝试过的
jQuery(未完成,这不起作用)
$(function() {
$(".mai").scroll(function() {
onScroll();
});
onScroll();
});
function onScroll() {
$(".main-p p").each(function(i) {
$(".main-p p").eq(i).removeClass("hl"); // mean highlight
var scrPos = $(".main-p p:nth-last-child(2)");
// I want to be second from the bottom of the "visible range" of .mai, not of <p>
if(scrPos < active) {
// If hl (= active) is above the second from the bottom of the range seen in .mai
$('.mai').scroll(function(e) {
e.preventDefault();
});
} else {
$('.mai').scroll();
// I want to return the scroll, but is this correct?
}
// I want to put processing to highlight with <p>, next <p>, next <p>..
$('.main-p .active').addClass('hl');
});
}
添加:当前状态
请看右侧。
当图像在左侧位置滚动时,会应用高亮。
但是,如果滚动到右侧句子位置,则不会应用高亮。
并且,如果按照上方左侧的幻灯片导航,图像将正确移动到该幻灯片,但我也想突出显示句子。(Swiper设置为同步图像和文本)
我在这个问题的第二张图片中发现了一个看起来还不错的东西(实际上 "the middle of the frame" 不错..)。-> scrollama.js
我想保持这个“Basic”。
它正在设置 nth-child(2)
,但我想将其更改为 scrollama 的“Basic”。
换句话说,我想要:
1) 当滚动到右侧的句子时突出显示
2) 左右同步
3) 将 nth-child(2)
更改为 scrollama 的“Basic”
我创建了一个分支,将最新答案添加了一张图像和 scrollama。请 fork 这个-> JSFiddle
变得更长了..
很抱歉,请务必谅解!

你能帮我一下吗?

。2)在HTML中添加一些<br>
。-> [JSFiddle](https://jsfiddle.net/__R2D2/cxeh6t3z/6/)但是,即使代码与我的本地代码完全相同,`<br>`在JSFiddle中也能正常工作。所以,我上传了我的实际本地情况[here](https://mqs2.com/broblem/br.html)。就像这样... - POPpre-line
