当我单击 div 时如何隐藏/显示兄弟姐妹 div

Question

我的网页上有多个 div。 当我单击名为singers-div 的父div 时，它假设仅在此div 中打开此<p>并在兄弟div中关闭<p> 。 但它不起作用。

注意：如果我尝试使用childern() ，它会给我一个错误。 mine.js:27 Uncaught TypeError: $(...).childern is not a function

你可以这样做：

 $(".singers-div").click(function() { if ($(this).find('p').css("display") == "none") { let singers = $(".singers").not(this); singers.each(function() { if ($(this).css("display") == "block") { $(this).slideUp(1000); } }); $(this).find('p').slideDown(1000); } else { $(this).find('p').slideUp(1000); } })

 h1, h2, p { margin: 0; }.singers { display: none; }.singers-head { cursor: pointer; }

Answer 2

在这一行：

$(this).find('.singers').siblings('p').slideUp(1000); 

.siblings 仅适用于具有相同父级的元素 - 不在同一“级别”（如果您愿意，可以是表亲）。 在您的 HTML 中，每个 the.singers 都在其自己的歌手分区中。

你需要 go 到一个共同的父母，然后找到所有的p.singers来隐藏它们：

$(this).closest(".container").find('p.singers')

 $(".singers-div").click(function() { $(this).closest(".container").find('p.singers').slideUp(1000); $(this).find('p').slideDown(1000); })

 h1, h2, p { margin: 0; }.singers { display: none; }.singers-head { cursor: pointer; }

为完整性编辑，您可以根据您的要求排除“当前”（很可能不会立即弹出和向下弹出 - 但可能是您希望它在第二次单击时隐藏，因此保留一个带有“当前”的变量" 段并根据需要将其排除）

 $(".singers-div").click(function() { var current = $(this).find('p').slideDown(1000); $(this).closest(".container").find('p.singers').not(current).slideUp(1000); })

 h1, h2, p { margin: 0; }.singers { display: none; }.singers-head { cursor: pointer; }
