我正在制作一个选项按钮（右上方的树点）。单击它时，必须显示选项。再次单击，隐藏选项。下面是我的代码，但它不起作用。你能看一下吗？

$("body").ready(function () {
    $(document).on("click", ".options-knop", function() {

        if (this.nextSibling.style.display == "none"){
            this.nextSibling.style.display = 'block !important';
        } else {
            this.nextSibling.style.display = 'none';
        }
    });
});
.img-wrapper {
    width: 100px;
    height: 100px;
    overflow: hidden;
    border-radius: 100%;
    float: left;
    margin: 5px;
}

.img-container {
    height: 100px;
}

.artist {
    transition: background-color 0.5s, color 0.5s;
    cursor: pointer;
}

.artist-outer {
    margin: 5px 0;
    padding: 10px 5px;
}

.artist .naam {

因为您正在使用JQuery，所以您可以使用 css() 功能：

if ( $(this).next().css('display') == "none")
     $(this).next().show();
else
     $(this).next().hide();

或者只是使用 toggle() 切换div show/hide的显示而不使用条件：

$(this).next().toggle();

希望这有帮助。

您可能想要使用jQuery.toggle 

$(document).ready(function () {
    $(document).on("click", ".options-knop", function() {
        $(this.nextSibling).toggle( );
    });
});

答案 3 :(得分：1)

首先，对我来说，如果不需要，我不想将jquery与纯Javascript混合

在你的代码中使用

$(document).ready();

而不是

$("body").ready

并使用

$("body").on();

而不是

$(document).on()

要使用jquery获取下一个元素，你需要使用 .next（）; ..所以jquery代码应该是这样的

$(document).ready(function () {
    $("body").on("click", ".options-knop", function() {

        $(this).next('.options-list').slideToggle();

    });
});
