微信小程序--动态切换登录注册标签页

1、try.js的

1.1、data函数

添加

activeTab: 'login', // 当前激活的标签，默认为登录

1.2、添加一个函数

// 切换登录/注册标签
  switchTab(e) {
    const tab = e.currentTarget.dataset.tab;
    this.setData({
      activeTab: tab
    });
  },

2、try.wxml的代码

<!--pages/try/try.wxml-->
<view class="login-container">
  <view class="header">
    <text class="logo">DataDevices</text>
    <text class="slogan">智能设备管理平台</text>
  </view>

  <view class="form-container">
    <view class="tab-container">
      <text class="tab-item {{activeTab === 'login' ? 'active' : ''}}" bindtap="switchTab" data-tab="login">登录</text>
      <text class="tab-item {{activeTab === 'register' ? 'active' : ''}}" bindtap="switchTab" data-tab="register">注册</text>
    </view>
  </view>
  
  <!-- 登录表单 -->
  <view wx:if="{{activeTab === 'login'}}" class="form">
  <view>登录表单</view>
  </view>

  <!-- 注册表单 -->
  <view wx:if="{{activeTab === 'register'}}" class="form">
  <view>注册表单</view>
  </view>

</view>

3、try.wxss

/* pages/try/try.wxss */
.login-container {
  padding: 40rpx;
  background-color: #f5f5f5;

  left: 25%;
  width: 50%;
