纬天建筑工程信息资讯网网站快速优化排名方法

直接上图上代码吧

// login/login.js
const app = getApp()
Page({/*** 页面的初始数据*/data: {},/*** 生命周期函数--监听页面加载*/onLoad(options) {},/*** 生命周期函数--监听页面初次渲染完成*/onReady() {},/*** 生命周期函数--监听页面显示*/onShow() {},/*** 生命周期函数--监听页面隐藏*/onHide() {},/*** 生命周期函数--监听页面卸载*/onUnload() {},/*** 页面相关事件处理函数--监听用户下拉动作*/onPullDownRefresh() {},/*** 页面上拉触底事件的处理函数*/onReachBottom() {},/*** 用户点击右上角分享*/onShareAppMessage() {},handleClick({currentTarget}){let userType = currentTarget.dataset.type// debuggerapp.globalData.userType =  currentTarget.dataset.typeconst targetPath = userType === 'a' ? '/pages/person/home/home' : '/pages/company/gift/gift';wx.switchTab({ url: targetPath }); // 关键：跳转到Tab页}
})

<!--login/login.wxml-->
<text>login/login.wxml</text>
<view><button data-type="a" bind:tap="handleClick">登陆个人</button></view>
<view><button data-type="b" bind:tap="handleClick">登陆企业</button></view>

1，这是我的目录解构

开启自定义tabbar开关custom：true，

然后list需要把所有tabar页面都注册进去

// app.json{"pages": ["login/login","pages/person/home/home","pages/person/vip/vip","pages/person/person/person","pages/company/gift/gift","pages/company/mine/mine","pages/company/order/order"],"tabBar": {"custom": true,"color": "#7A7E83","selectedColor": "#3cc51f","borderStyle": "black","backgroundColor": "#ffffff","list": [{ "pagePath": "pages/person/home/home", "text": "首页"},{ "pagePath": "pages/person/vip/vip", "text": "会员"},{ "pagePath": "pages/person/person/person", "text": "个人中心"},{ "pagePath": "pages/company/gift/gift", "text": "礼品"},{ "pagePath": "pages/company/order/order", "text": "订单"},{ "pagePath": "pages/company/mine/mine", "text": "我的"}]},"window": {"backgroundTextStyle": "light","navigationBarBackgroundColor": "#fff","navigationBarTitleText": "WeChat","navigationBarTextStyle": "black"},"usingComponents": {}
}

2.自定义tabbar文件夹  custom-tab-bar

// custom-tab-bar/index.js
Component({data: {tabList: [],     // 根据用户类型动态设置activeIndex: 0   // 当前选中Tab},methods: {switchTab(e) {// const path = e.currentTarget.dataset.path;// const index = e.currentTarget.dataset.index;// wx.switchTab({ url: path });// this.setData({ activeIndex: index });const { path, index } = e.currentTarget.dataset;console.log(path)wx.switchTab({url: path,success: () => {console.log('跳转成功');this.setData({ activeIndex: index });},fail: (err) => {console.error('跳转失败:', err);}});},// 根据用户类型更新Tab列表updateTabList(userType) {const tabs = {a: [{ pagePath: "/pages/person/home/home", text: "首页"},{ pagePath: "/pages/person/vip/vip", text: "会员"},{ pagePath: "/pages/person/person/person", text: "个人中心"}],b: [{ pagePath: "/pages/company/gift/gift", text: "礼品"},{ pagePath: "/pages/company/order/order", text: "订单"},{ pagePath: "/pages/company/mine/mine", text: "我的"}]};this.setData({ tabList: tabs[userType] });}},
});

//index.json{"component": true
}

<!-- custom-tab-bar/index.wxml -->
<!-- <view class="tab-bar"><block wx:for="{{tabList}}" wx:key="index"><view class="tab-item {{activeIndex === index ? 'active' : ''}}" bindtap="switchTab"data-path="{{item.pagePath}}"data-index="{{index}}"><image src="{{activeIndex === index ? item.selectedIconPath : item.iconPath}}"></image><text>{{item.text}}</text></view></block>
</view> -->
<!-- custom-tab-bar/index.wxml -->
<cover-view class="tab-bar"><block wx:for="{{tabList}}" wx:key="index"><cover-view class="tab-item {{activeIndex === index ? 'active' : ''}}"bindtap="switchTab"data-path="{{item.pagePath}}"data-index="{{index}}"><cover-image class="tab-icon" src="{{activeIndex === index ? item.selectedIconPath : item.iconPath}}" /><cover-view class="tab-text">{{item.text}}</cover-view></cover-view></block>
</cover-view>

/* custom-tab-bar/index.wxss */
.tab-bar {position: fixed;bottom: 0;left: 0;right: 0;height: 100rpx; /* 高度与原生TabBar一致 */background: #ffffff;display: flex;align-items: center;justify-content: space-around;box-shadow: 0 -2rpx 10rpx rgba(0,0,0,0.05); /* 顶部阴影 */z-index: 9999; /* 确保层级最高 */
}.tab-item {display: flex;flex-direction: column;align-items: center;justify-content: center;height: 100%;padding: 0 20rpx;
}.tab-icon {width: 48rpx;height: 48rpx;margin-bottom: 4rpx;
}.tab-text {font-size: 20rpx;color: #666666;
}/* 选中状态样式 */
.tab-item.active .tab-text {color: #007AFF; /* 主题色 */
}.tab-item.active .tab-icon {filter: brightness(0.8); /* 图标选中效果 */
}

3.自定义util

// util/changetab.js
const app = getApp()
module.exports = Behavior({methods: {updateTabBarIndex(index) {const userType = app.globalData.userType;const tabBar = this.getTabBar();if (tabBar) {tabBar.updateTabList(userType);tabBar.setData({ activeIndex: index })};}}
});

z最后在各个tabbar对于的页面的onshow中引入util方法

// pages/person/home/home.js
const changeTab = require('../../../util/changeTab')
Page({behaviors:[changeTab],/*** 页面的初始数据*/data: {},/*** 生命周期函数--监听页面显示*/onShow() {this.updateTabBarIndex(0); },/*** 生命周期函数--监听页面隐藏*/onHide() {},/*** 生命周期函数--监听页面卸载*/onUnload() {},/*** 页面相关事件处理函数--监听用户下拉动作*/onPullDownRefresh() {},/*** 页面上拉触底事件的处理函数*/onReachBottom() {},/*** 用户点击右上角分享*/onShareAppMessage() {}
})
