问题描述
我有一个隐藏的功能列表,单击按钮可以取消隐藏它们.在项目之间还有另一个执行相同操作的列表:隐藏直到单击按钮.这是一个示例:
I have a list in function that are hidden and a click of a button unhides them. There's another list in between items that does the same thing: hidden until a button is clicked. Here's an example:
- 1
- 2
- 3a
- 3b
- 3c
- 4
- 5
它可以正常工作到3c结束.当我单击一个按钮继续时,所有内容都消失了.我正在尝试找到一种方法,当更改为第二个列表时,可以继续取消隐藏第一个列表中的列表.
It works fine until the end of 3c. When I click a button to continue, everything disappears. I'm trying to find a way to continue to unhide a list in the first list when changing to the second list.
我的代码:单击下一步".当3a出现时,单击"multi next",直到3c.当点击3c之后的下一步"时,它消失了.假设4显示然后5
My code: Click on 'single next' to advance. When 3a appears, click 'multi next' until 3c. When click on 'single next' after 3c, it disappears. 4 is suppose to show then 5
$("#multi-single-next").click(function () {
var index = $('.pagnation').find('li:visible').index();
if ($(this).hasClass('prev')) {
index = index == 0 ? 0 : (index - 1);
} else {
var totalLiElem = $('.pagnation').find('li').length
index = (index == (totalLiElem - 1)) ? (totalLiElem - 1) : (index + 1);
}
$('.pagnation').find('li:visible').fadeToggle("fast", "linear", function() {
$('.pagnation').find('li:eq(' + index + ')').fadeToggle(550, "linear");
});
});
$('.pagnation-2 li:gt(0)').hide();
$('#multi-next-multi-item').click(function() {
var last = $('.pagnation-2').children('li:visible:last');
last.nextAll(':lt(1)').fadeToggle('slow').show();
last.next().prevAll().fadeToggle('slow').hide();
});
.pagnation li {
display: inline-block;
list-style: none;
}
.pagnation li:not(:first-child) {
display: none;
}

推荐答案
这就是您想要的?
我删除索引,并使用类active
作为当前索引.可以使用 .next 兄弟来简单显示下一个LI.
I remove index and use class active
instead as current index.Next LI can be simple simply showed with using .next sibling.
$('#multi-single-next').click(function() {
let $item;
if(!$('ul.pagnation li.single-data-item.active').length) {
$item = $('ul.pagnation li.single-data-item').first();
}
else {
$prev = $('ul.pagnation li.single-data-item.active');
$item = $prev.next();
if(!$prev.next().length) {
$prev.removeClass('active');
$prev.hide();
return;
}
$prev.removeClass('active');
$prev.hide();
}
$item.addClass('active');
$item.show();
// sub items
$('ul.pagnation-2 li').removeClass('active');
if($item.hasClass('has-multi-items')) {
const $sub = $item.find('ul li').first();
$sub.addClass('active');
$sub.show();
}
});
$('#multi-next-multi-item').click(function() {
const $item = $('ul.pagnation-2 li.active');
const $next = $item.next();
$item.removeClass('active');
$item.hide();
$next.addClass('active');
$next.show();
});
