【中文标题】Jquery - 遍历每个按钮以显示隐藏的 div

【英文标题】：Jquery - loop through each button to show the hidden 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。

【参考方案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();
        )
    );
