单击不同项目时切换展开/折叠箭头

Question

我正在编写简单的常见问题解答部分，我需要一些帮助。

问题是当我在问题之间切换时，展开/折叠箭头将保持向上。你有什么建议吗？

$(document).ready(function(){
    var nadpis = $('.nadpis');
    nadpis.on('click', function () {
        $(this).siblings().slideToggle()
        $(this).children().toggleClass("off on")
        nadpis.not(this).siblings().slideUp();
    });
});

.textbox:first-child p {
    display: none;
}

.nadpis {
    display: flex;
    flex-direction: row;
    align-items: baseline;
    justify-content: space-between;
    gap: 5em;
    border-bottom: 1px solid;
}

.off i:nth-child(2) {
    display: none;
}

.off i:first-child {
    display: block;
}

.on i:nth-child(2) {
    display: block;
}

.on i:first-child {
    display: none;
}

这里已满code pen

Answer 1

您的toggleClass 调用只会影响点击项目的内容。扩展这个效果的范围：首先选择容器元素，然后找到所有相关的“on”元素，以及被点击项下方的“off”元素，并切换它们：

$(this).closest(".faq-text").find(".on")
       .add($(this).find(".off"))
       .toggleClass("off on")

片段：

$(document).ready(function(){
    var nadpis = $('.nadpis');
    nadpis.on('click', function () {
        $(this).siblings().slideToggle()
        $(this).closest(".faq-text").find(".on")
               .add($(this).find(".off"))
               .toggleClass("off on")
        nadpis.not(this).siblings().slideUp();
    });
});

.textbox p {
    display: none;
}

.nadpis {
    display: flex;
    flex-direction: row;
    align-items: baseline;
    justify-content: space-between;
    gap: 5em;
    border-bottom: 1px solid;
}

.off i:nth-child(2) {
    display: none;
}

.off i:first-child {
    display: block;
}

.on i:nth-child(2) {
    display: block;
}

.on i:first-child {
    display: none;
}

无关言论

确保在页面加载时隐藏所有涉及的 <p> 元素。在 CSS 中替换这个：

.textbox:first-child p {
    display: none;
}

...只有这个：

.textbox p {
    display: none;
}
