Question

当您单击内容上方的选项卡时，我只创建了一个用Jquery显示/隐藏内容的脚本（它还会更改单击的选项卡的颜色）。一切正常（结果：https://jsfiddle.net/e572s3oq/embedded/result/）但我认为还有另一种方法可以在内容之间切换，从而更容易添加更多标签。如果有人可以帮助我，我会很高兴。我希望你理解我的意图。（请原谅我的英语并问我是否还有其他问题）

这是我的代码（我认为只有jQuery代码是相关的）：

＆＃13;

    $(document).ready(function() {
  $(".tab:first-child").click(function() {
    $(".content p:nth-child(2)").css('display', 'none');
    $(".tab:nth-child(2)").css('background-color', '#F5F7F7');
    $(".tab:first-child").css('background-color', 'white');
    $(".content p:first-child").css('display', 'block');
  });

  $(".tab:nth-child(2)").click(function() {
    $(".content p:first-child").css('display', 'none');
    $(".tab:first-child").css('background-color', '#F5F7F7');
    $(".tab:nth-child(2)").css('background-color', 'white');
    $(".content p:nth-child(2)").css('display', 'block');
  });

});

＆＃13;

body,
html {
  padding: 0;
  margin: 0;
  background-color: #ecf0f1;
}
#wrapper {
  width: 260px;
  margin: auto;
  margin-top: 100px;
}
.tab {
  width: 130px;
  height: 30px;
  font-family: 'Lato', sans-serif;
  font-size: 14px;
  line-height: 30px;
  text-align: center;
  color: #7f8c8d;
  display: block;
  float: left;
}
.tab:hover {
  cursor: pointer;
}
.tab:first-child {
  background-color: white;
}
.tab:nth-child(2) {
  background-color: #F5F7F7;
}
.content {
  width: 260px;
  height: 300px;
  background-color: white;
  overflow: scroll;
}
.content p {
  color: #7f8c8d;
  font-size: 12px;
  font-family: 'Lato', sans-serif;
  margin-top: 8px;
  margin-left: 8px;
  margin-right: 8px;
  margin-bottom: 5px;
}
.content p:first-child {
  display: block;
}
.content p:nth-child(2) {
  display: none;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id=wrapper>
  <div class="tab">
    PAGE 1
  </div>

  <div class="tab">
    PAGE 2
  </div>

  <div class="content">
    <p>Content1</p>
    <p>Content2</p>
  </div>
</div>

Answer 1

这应该做：

$('.tab').click(function() {
    $('.content p').hide();
    $('.tab').css('background-color', '#F5F7F7');
    $(this).css('background-color', 'white');
    $('.content p').eq($(this).index()).css('display', 'block');
});

基本上发生的是：

我们首先默认隐藏p div中的所有.content元素。
我们还为所有background-color元素设置#F5F7F7至.tab。
然后，您可以使用.tab定位当前$(this)元素，并将其background-color设置为white。
最后，我们可以使用当前p元素的当前 .index() 来定位.content div中的特定.tab元素，然后我们将这个.index()提供给另一个名为 .eq() 的jQuery方法，然后我们将获得所需的p元素。

<强> 段：

$('.tab').click(function() {
    $('.content p').hide();
    $('.tab').css('background-color', '#F5F7F7');
    $(this).css('background-color', 'white');
    $('.content p').eq($(this).index()).css('display', 'block');
});

body, html {
    padding:0;
    margin:0;
    background-color:#ecf0f1;

#wrapper {

    margin: auto;
    margin-top:100px;

    font-family:'Lato', sans-serif;
    font-size:14px;
    line-height: 30px;
    text-align: center;
    color:#7f8c8d;
    display: block;
    float: left;
    background-color: #F5F7F7;
}
.tab:hover { cursor:pointer; }
.tab:first-child { background-color: white; }
.content {
    width:260px;
    height:300px;
    background-color:white;
    overflow: scroll;
}

    color:#7f8c8d;

    margin-top:8px;
    margin-left:8px;

在CSS中修改了一些样式，并在HTML中为上述代码段添加了更多内容。希望这会有所帮助。

使用jquery
