支付宝小程序重写tabbar底部导航，供大家参考，具体内容如下

1.app.js中代码如下

editTabBar: function () { var e = this.globalData.tabbar, a = getCurrentPages(), t = a[a.length - 1], s = t.route; console.log(t) console.log(s) 0 != s.indexOf("/") && (s = "/" + s); for (var n in e.items) e.items[n].selected = !1, e.items[n].pagePath == s && (e.items[n].selected = !0); t.setData({ tabbar: e }); }, globalData: { userInfo: null, //配置tabbar tabbar: { textColor: "#333", selectedColor: "#d0501f", backgroundColor: "#ffffff", borderStyle: "#d5d5d5", items: [{ pagePath: "/pages/seller/gzt/gzt", name: "工作台", icon: "/pages/icon/index.png", activeIcon: "/pages/icon/index_1.png", selected: !0 },{ pagePath: "/pages/seller/shezhi/shezhi", name: "设置", icon: "/pages/images/sz@3x.png", activeIcon: "/pages/images/xzsz.png", selected: !1 }], position: "bottom" } }

2.template.axml代码如下

<template name="tabbar"> <view class="tabbar_box" style="background-color:{{tabbar.backgroundColor}}; border-top-color:{{tabbar.borderStyle}}; {{tabbar.position=='top'?'top:0':'bottom:0'}}"> <navigator class="tabbar_nav" openType="redirect" style="width:{{1/tabbar.items.length*100}}%; color:{{item.selected?tabbar.selectedColor:tabbar.textColor}}" url="{{item.pagePath}}" a:for="{{tabbar.items}}" a:key="index"> <image class="tabbar_icon" src="{{item.selected?item.activeIcon:item.icon}}"></image> <text>{{item.name}}</text> </navigator> </view></template>

3.template.acssl代码如下

.tabbar_box { display: -webkit-box; display: -ms-flexbox; display: flex; -webkit-box-orient: horizontal; -webkit-box-direction: normal; -ms-flex-direction: row; flex-direction: row; -ms-flex-pack: distribute; justify-content: space-around; position: fixed; bottom: 0; left: 0; z-index: 999; width: 100%; height: 100rpx; border-top: 0.5rpx solid #d5d5d5;}.tabbar_nav { display: -webkit-box; display: -ms-flexbox; display: flex; -webkit-box-orient: vertical; -webkit-box-direction: normal; -ms-flex-direction: column; flex-direction: column; -webkit-box-pack: center; -ms-flex-pack: center; justify-content: center; -webkit-box-align: center; -ms-flex-align: center; align-items: center; font-size: 25rpx; height: 100%;}.tabbar_icon { width: 40rpx; height: 40rpx;}

4.在需要引入的页面(.axml)中

- <import src="../template.axml"></import><template is="tabbar" data="{{tabbar:tabbar}}"></template>

5.在需要引入的样式(acss)中

@import "../template.acss";

6.在需要引入的js中

var app=getApp(); //放在顶部 tabbar:{}, //放在data中 app.editTabBar(); //放在onLoad中
