单击时如何让菜单栏中的 A href link 在正文中打开一个关闭的手风琴？ - html

Question

单击名为“打开第一个手风琴”的 href 时如何打开第一个手风琴，而第二个 href 也是如此？手风琴本身 100% 正常工作，我只想在单击菜单栏中的 href 按钮时从其范围之外访问它。

$(".expand").on("click", function () {
    $(".right-arrow").text("+");
    $(".detail:visible").slideUp();
    if(!$(this).next().is(":visible")){

        $(this).next().slideDown(200);
        $(this).find(".right-arrow").text("-");
    }
});

Answer 1

在顶部标记中添加一个 class a:

<a class="accord" href=""> Open 1st accordion </a> <br>
<a class="accord" href=""> Open 2nd accordion </a> 

接下来，利用each()方法和index参数，将点击事件的逻辑写在a这些标签上。

使用 event.preventDefault() 禁用 a 标签的默认行为。

并使用 trigger() 方法，使用具有适当 index[=48= 的 eq() 在 .expand class 上调用点击事件]:

$(".expand").eq(index).trigger('click');

这样，我们得到了如下代码。只需将它添加到您的主代码即可。

$('.accord').each(function(index) {
  $(this).click(function(event) {
    event.preventDefault();
    $(".expand").eq(index).trigger('click');
  });
});

编辑：

修改了 jquery 代码，考虑到了 localStorage().

$(document).ready(function () {
    $(".expand").on("click", function () {
        $(".right-arrow").text("+");
        $(".detail:visible").slideUp();
        if (!$(this).next().is(":visible")) {
            $(this).next().slideDown(200);
            $(this).find(".right-arrow").text("-");
        }
    });

    let click_state = localStorage.getItem("click_state");
    let ind = localStorage.getItem("ind");

    if (click_state == 1) {
        $(".expand").eq(ind).trigger("click");

        localStorage.removeItem("click_state");
        localStorage.removeItem("ind");
    } else {
    }

    $(".accord").each(function (index) {
        $(this).click(function (event) {
            event.preventDefault();

            localStorage.setItem("click_state", 1);
            localStorage.setItem("ind", index);
        });
    });
});
