支付宝小程序tabbar底部导航

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
