删除 div 部分下方的空白区域

Question

我有一个包含两个图像的 div，当单击每个图像时，它们会显示一些文本。

 $('span.a, span.b').click(function() { if (!$(this).hasClass('active')) { $('span.a, span.b').removeClass('active'); $(this).addClass('active'); $('div.a, div.b').toggle(); } $('div.a, div.b').css("visibility","visible") });

 div.a, div.b { visibility:hidden; } .footer { font-family:'Arial'; font-size:13px; background-color:#000; color:#fff; text-align:center; padding:20px; }

 <div style="background-color:#fff;"><center><span class="a active"> <img src="http://cornerstoneparking.portfolio.com.au/wp-content/uploads/2016/10/Customers.jpg" width="200"> </span> <span class="b"> <img src="http://cornerstoneparking.portfolio.com.au/wp-content/uploads/2016/12/Landlords.jpg" width="200"></span> <div class="a">Cornerstone Parking provides value for money parking in Brisbane's CBD and surrounding suburbs.

我有两个问题：我需要最小化第一个 div 中两个图像下方的大空白 - 可以这样做吗？

当再次单击图像时，Javascript 代码是否可能再次隐藏文本？

谢谢！

Answer 1

额外的空间来自使用visibility: hidden; 这将在页面上留下隐藏内容的布局，但在视觉上隐藏它（所以它是不可见的）。 使用display: none; 而是从页面中删除内容的布局，就好像它从未存在过一样。

然后您可以简化您的 jQuery，只需切换一个类来指定活动/非活动图像，然后在 CSS 中使用同级选择器来显示活动内容。

 $('span.a, span.b').click(function() { $(this).siblings().removeClass('active'); $(this).toggleClass('active'); });

 div.a, div.b { display: none; } .a.active ~ .a, .b.active ~ .b { display: block; } .footer { font-family:'Arial'; font-size:13px; background-color:#000; color:#fff; text-align:center; padding:20px; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div style="background-color:#fff;"> <center><span class="a active"> <img src="http://cornerstoneparking.portfolio.com.au/wp-content/uploads/2016/10/Customers.jpg" width="200"> </span> <span class="b"> <img src="http://cornerstoneparking.portfolio.com.au/wp-content/uploads/2016/12/Landlords.jpg" width="200"></span> <div class="a">Cornerstone Parking provides value for money parking in Brisbane's CBD and surrounding suburbs.

Answer 2

您的 JavaScript 函数仅检查该类是否处于活动状态

if (!$(this).hasClass('active'))

您应该编写一个 else 语句来切换可见性。

空白是一个样式问题。 您应该在 CSS 中编辑边距/填充。
