Jquery - 遍历每个按钮以显示隐藏的 div答案

【问题标题】：Jquery - loop through each button to show the hidden divJquery - 遍历每个按钮以显示隐藏的 div

【问题描述】：

我有六个带有六个按钮的框，当我悬停每个单独的按钮时，我想显示一个附加到每个框的单独隐藏 div。如您所见，我已经为第一个框完成了它（现在，所有按钮都附加在它上面），但我想知道循环遍历每个单独按钮以显示相应隐藏 div 的理想/正确方法。

$(document).ready(function() {
  $(".hiddenOne, .hiddenTwo, .hiddenThree, .hiddenFour, .hiddenFive, .hiddenSix").hide();
  $(".button").each(function(index) {
    $(".button").hover(function() {
      $(".hiddenOne").fadeIn();
    });
    $(".hiddenOne").mouseleave(function() {
      $(".hiddenOne").fadeOut();
    });
  });
});

【问题讨论】：

您有多确定 jQuery 是实现这种效果的最佳方式，而不仅仅是 CSS？
我正在开发一个 jquery 解决方案，待命
如果按钮被隐藏的 div 覆盖，您打算如何单击该按钮？
该按钮不是隐藏 Div 的一部分。 @AlexanderNied，可以通过 CSS 做到这一点，但网站的其余部分也使用 JQuery 来制作基本动画，所以这是出于一致性和结构原因。

【解决方案1】：

你可以这样试试：

$(document).ready(function() {
        $(".hiddenOne").hide();

        $(".button").hover(function () {
            $(this).parent().find('.hiddenOne').fadeIn();
        })

        $(".hiddenOne").mouseleave(function () {
            $(this).fadeOut();
        })
    });

* {
        box-sizing: border-box;
        margin: 0;
        padding: 0;
    }

    .centerThis {
        text-align: center;
        margin-top: 20px;
    }

    .center2 {
        text-align: center;
        background-color: red;
    }

    .container {
        padding-top: 50px;
        display: flex;
        /* establish flex container */
        flex-wrap: wrap;
        /* enable flex items to wrap */
        justify-content: space-around;
    }

    .button {
        background: red;
        color: white;
        padding: 10px;
    }
    
    .white {
        color: white;
        text-align: center;
        padding-top: 50px;
    }

    .hiddenOne {
        height: 300px;
        padding-top: 20px;
        background-color: red;
        color: white;
    }
    
    .itemWithin {
        flex: 0 35%;
        height: 300px;
        margin-bottom: 2%;
        background-color: grey;
    }
