jQuery e.preventDefault仅在第一次单击时不起作用

Question

我在防止点击按钮时跳转部分有问题。我的代码是：

脚本：

    $('.read-more').on('click', function (e) {
        e.preventDefault();
        $(".active").each(function () {
            $(this).removeClass("active");
        });
        var target = $(this).attr('data-toggle');
        $("#" + target).show().siblings("div").hide();
        $(this).closest("article").find(".read-more").each(function () {
            $(this).toggleClass('active');
        });
        $(this).closest("article").find(".arrow-marker").each(function () {
            $(this).toggleClass('active');
        });
        return false
    });

HTML：

    <article class="service">
        <a href="#" class="read-more" data-toggle="expand1"></a>
        <button class="read-more" data-toggle="expand1">Read More</button>
        <span class="arrow-marker"></span>
    </article>
    <article class="service">
        <a href="#" class="read-more" data-toggle="expand2"></a>
        <button class="read-more" data-toggle="expand2">Read More</button>
        <span class="arrow-marker"></span>
    </article>
    <article class="service">
        <a href="#" class="read-more" data-toggle="expand3"></a>
        <button class="read-more" data-toggle="expand3">Read More</button>
        <span class="arrow-marker"></span>
    </article>
    <article class="service">
        <a href="#" class="read-more" data-toggle="expand4"></a>
        <button class="read-more" data-toggle="expand4">Read More</button>
        <span class="arrow-marker"></span>
    </article>

    <div id="expand1"></div>
    <div id="expand2"></div>
    <div id="expand3"></div>
    <div id="expand4"></div>

这个脚本的基本功能是切换4个选项卡和相关的类。我需要做同样的事情。

我必须说，它工作得很好，只有第一次点击任何选项卡都会跳到页面的顶部，之后的每一次点击都很好。你能找出代码出了什么问题吗？我知道可能有更好的解决方案。

提前感谢！

我不完全确定它是否会有帮助，但尝试像这样使用.on：

$('body').on('click', '.read-more', function(){});

<script>
$(document).ready(function() {
   $('.read-more').on('click', function (e) {
        e.preventDefault();
        $(".active").each(function () {
            $(this).removeClass("active");
        });
        var target = $(this).attr('data-toggle');
        $("#" + target).show().siblings("div").hide();
        $(this).closest("article").find(".read-more").each(function () {
            $(this).toggleClass('active');
        });
        $(this).closest("article").find(".arrow-marker").each(function () {
            $(this).toggleClass('active');
        });
        return false
    });
 });
</script>

Answer 3

编辑:我找到了解决方案，问题出在.active类中。Bootstrap carousel有激活的类，我已经瞄准了页面上的所有激活的类...在点击的时候，旋转木马消失了，这导致了跳跃...愚蠢的我。

感谢大家的帮助！
