标签-需要内容在页面加载时隐藏并在单击时显示

Question

我已经创建了一个标签系统。 它在JSFiddle上似乎最合适，因为我需要它，但在这里运行错误代码，并且我需要首先隐藏两个选项卡上的选项卡内容，并且仅在单击选项卡（图像）时才显示。 任何人都可以帮助解决这些问题吗？

我是Java的新手。 提前致谢。

我对Java语言只是一个新手，所以需要一些帮助。 提前致谢！

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

Answer 1

在body标签的末尾添加jQuery（在代码段中是html代码的末尾）可以解决您的问题。

如果您想知道的话，请告诉我。

由于您的js代码使用jQuery库语法，因此您需要添加jQuery库，如下所示：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>

对于隐藏部分，您可以通过以下方式使div隐藏：

div.a,
div.b {
  visibility:hidden;
}

然后在js中将可见性编辑为点击可见

$('div.a, div.b').css("visibility","visible")

可见性隐藏了内容，但仍会占用空间。 如果要让不可见内容占据页面中的任何空间，请使用“ display” css属性而不是可见性。

您可以在下面找到完整的代码：

 $('span.a, span.b').click(function() { if (!$(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 { margin-top: 40px; width: 80%; text-align: left; } div.a, div.b { visibility:hidden; } 

 <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.
