javascript - 如何通过单击另一个链接来打开切换功能

Question

我正在尝试创建一个向下滚动到切换功能并在向下滚动时自动打开的功能。

<a href="#!" id="linkbro">click me </a>

<div id="fine">
    <button class="show_hide">Toggle</button>
    <p class="content">
     This is the paragraph to end all paragraphs.  You
     should feel <em>lucky</em> to have seen such a paragraph in
     your life.  Congratulations!
    </p>
</div>

我的 JavaScript。向下滚动功能有效，但切换开关未打开。

$(document).ready(function () {
    $(".content").hide();
    $("#linkbro").click(function() {
        $('html, body').animate({
            scrollTop: $("#fine").offset().top - 50
        }, 2000);
        $(this).next('.content').slideToggle(200);
    });
});

Answer 1

您可以使用$(this).siblings。更改:
$(this).next('.content').slideToggle(200);
致:
$(this).siblings('div').find('.content').slideToggle(200);

也许您希望您的切换按钮是这样的？

$('.show_hide').click(function(){
    $(this).next('.content').slideToggle(200);
});  

这是您更新的脚本:

<script>
$(document).ready(function() {
    $(".content").hide();

    $("#linkbro").click(function() {
        $('html, body').animate({
            scrollTop: $("#fine").offset().top - 50
        }, 2000);
        $(this).siblings('div').find('.content').slideToggle(200);
    });

    $('.show_hide').click(function(){
        $(this).next('.content').slideToggle(200);
    });
});
</script>
