微信小程序tabBar模板用法实例分析【附demo源码下载】

<template name="tabBar">
 <view class="flex-h flex-hsb tab-bar" style="color: {{tabBar.color}}; background: {{tarBar.backgroundColor}}; {{tabBar.position=='top'">
 <block wx:for="{{tabBar.list}}" wx:key="pagePath">
  <navigator url="{{item.pagePath}}" open-type="redirect" class="menu-item" style="{{item.active">
   <image src="/UploadFiles/2021-04-02/{{item.selectedIconPath}}">

接下来进行测试，首先是index.js的配置对象：


//配置tabBar
  tabBar: {
   "color": "#9E9E9E",
   "selectedColor": "#f00",
   "backgroundColor": "#fff",
   "borderStyle": "#ccc",
   "list": [
    {
     "pagePath": "/pages/index/index",
     "text": "主页",
     "iconPath": "../../img/tabBar_home.png",
     "selectedIconPath": "../../img/tabBar_home_cur.png",
     //"selectedColor": "#4EDF80",
     active: true
    },
    {
     "pagePath": "/pages/village/city/city",
     "text": "目的地",
     "iconPath": "../../img/tabBar_village.png",
     "selectedIconPath": "../../img/tabBar_village_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    },
    {
     "pagePath": "/pages/mine/mine",
     "text": "我的",
     "iconPath": "../../img/tabBar_mine.png",
     "selectedIconPath": "../../img/tabBar_mine_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    }
   ],
   "position": "bottom"
  }




index.wxml引入模板：


<import src="/UploadFiles/2021-04-02/tabBar.wxml">

接下来是mine.js文件引入配置对象：


//配置tabBar
  tabBar: {
   "color": "#9E9E9E",
   "selectedColor": "#f00",
   "backgroundColor": "#fff",
   "borderStyle": "#ccc",
   "list": [
    {
     "pagePath": "/pages/index/index",
     "text": "主页",
     "iconPath": "../../img/tabBar_home.png",
     "selectedIconPath": "../../img/tabBar_home_cur.png",
     //"selectedColor": "#4EDF80",
     active: false
    },
    {
     "pagePath": "/pages/village/city/city",
     "text": "目的地",
     "iconPath": "../../../img/tabBar_village.png",
     "selectedIconPath": "../../../img/tabBar_village_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    },
    {
     "pagePath": "/pages/mine/mine",
     "text": "我的",
     "iconPath": "../../img/tabBar_mine.png",
     "selectedIconPath": "../../img/tabBar_mine_cur.png",
     "selectedColor": "#4EDF80",
     active: true
    }
   ],
   "position": "bottom"
  }




mine.wxml引入模板：


<import src="/UploadFiles/2021-04-02/tabBar.wxml">

最后演示如下：

方案二，我把配置数据统一放在app.js文件，通过点击跳转页面后在把数据添加到当前页面实例上，具体做法如下：
1、app.js文件配置：


//app.js
var net = require('common/net');
var a_l, a_d = {}, a_cbSucc, a_cbSuccFail, a_cbFail, a_cbCom, a_h, a_m;
App({
 onLaunch: function () {
  var that = this;
 },
 //修改tabBar的active值
 editTabBar: function () {
  var _curPageArr = getCurrentPages();
  var _curPage = _curPageArr[_curPageArr.length - 1];<span style="font-family: Arial, Helvetica, sans-serif;">//相当于Page({})里面的this对象</span>
  var _pagePath=_curPage.__route__;
  if(_pagePath.indexOf('/') != 0){
   _pagePath='/'+_pagePath;
  }
  var tabBar=this.globalData.tabBar;
  for(var i=0; i<tabBar.list.length; i++){
   tabBar.list[i].active=false;
   if(tabBar.list[i].pagePath==_pagePath){
    tabBar.list[i].active=true;//根据页面地址设置当前页面状态
   }
  }
  _curPage.setData({
   tabBar: tabBar
  });
 },
 globalData: {
  userInfo: null,
  //配置tabBar
  tabBar: {
   "color": "#9E9E9E",
   "selectedColor": "#f00",
   "backgroundColor": "#fff",
   "borderStyle": "#ccc",
   "list": [
    {
     "pagePath": "/pages/index/index",
     "text": "主页",
     "iconPath": "/pages/templateImg/tabBar_home.png",
     "selectedIconPath": "/pages/templateImg/tabBar_home_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    },
    {
     "pagePath": "/pages/village/city/city",
     "text": "目的地",
     "iconPath": "/pages/templateImg/tabBar_village.png",
     "selectedIconPath": "/pages/templateImg/tabBar_village_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    },
    {
     "pagePath": "/pages/mine/mine",
     "text": "我的",
     "iconPath": "/pages/templateImg/tabBar_mine.png",
     "selectedIconPath": "/pages/templateImg/tabBar_mine_cur.png",
     "selectedColor": "#4EDF80",
     active: false
    }
   ],
   "position": "bottom"
  }
 }
})




2、index.js+mine.js+city.js页面使用：


var App=getApp();
Page({
 data:{
  detail: {},
 },
 onLoad:function(options){
  App.editTabBar();//添加tabBar数据
  var that=this;
 }
})




最终演示和上图一致！
