微信小程序重写tabbar底部导航,供大家参考,具体内容如下

1.app.js代码如下:

editTabBar: function() {
    var e = this.globalData.tabbar, a = getCurrentPages(), t = a[a.length - 1], s = t.__route__;
    0 != s.indexOf("/") && (s = "/" + s);
    for (var n in e.list) e.list[n].selected = !1, e.list[n].pagePath == s && (e.list[n].selected = !0);
    t.setData({
      tabbar: e
    });
  },
  tabBar: {
    color: "#123",
    selectedColor: "#1ba9ba",
    borderStyle: "#1ba9ba",
    backgroundColor: "#fff",
    list: [ {
      pagePath: "/we7/pages/index/index",
      iconPath: "/we7/resource/icon/home.png",
      selectedIconPath: "/we7/resource/icon/homeselect.png",
      text: "首页"
    }, {
      pagePath: "/we7/pages/user/index/index",
      iconPath: "/we7/resource/icon/user.png",
      selectedIconPath: "/we7/resource/icon/userselect.png",
      text: "我的"
    } ]
  },
  globalData: {
    userInfo: null,
    tabbar: {
      color: "#333",
      selectedColor: "#d0501f",
      backgroundColor: "#ffffff",
      borderStyle: "#d5d5d5",
      list: [ {
        pagePath: "/pages/seller/gzt",
        text: "工作台",
        iconPath: "/pages/images/gzt@3x.png",
        selectedIconPath: "/pages/images/gztxz@3x.png",
        selected: !0
      }, {
        pagePath: "/pages/seller/cp/cplb",
        text: "商品",
        iconPath: "/pages/images/dbdc.png",
        selectedIconPath: "/pages/images/dbdcxz.png",
        selected: !1
      }, 
      position: "bottom"
    }
  },

template.wxml

<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.list.length*100}}%; color:{{item.selected?tabbar.selectedColor:tabbar.color}}" url="{{item.pagePath}}" wx:for="{{tabbar.list}}" wx:key="index">
      <image class="tabbar_icon" src="{{item.selected?item.selectedIconPath:item.iconPath}}"></image>
      <text>{{item.text}}</text>
    </navigator>
  </view>
</template>

3.template.wxss

.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;
}

在需要用的页面(wxml)添加如下代码

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

在需要的样式(wxss)添加如下代码

@import "template.wxss";

在需要的js页面添加如下代码:

var dsq, app = getApp();添加在顶部
tabbar: {},在data中添加
app.editTabBar();在onLoad中添加

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持三水点靠木。
