微信小程序重寫tabbar底部導航，供大家參考，具體內容如下
1.app.js代碼如下：
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: "首頁"
}, {
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: "工作臺",
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" >
<navigator class="tabbar_nav" openType="redirect" 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;

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;

align-items: center;
font-size: 25rpx;
height: 100%;
}
.tabbar_icon {
width: 40rpx;
height: 40rpx;
}
在需要用的頁面(wxml)添加如下代碼

在需要的樣式（wxss）添加如下代碼
@import "template.wxss";
