# 微信小程序（跳页之tabBar导航跳转） #

# tabBar小程序导航 #

# 简介： #

小程序是一个多tab标签应用（客户端窗口的底部或顶部有tab栏可以切换页面），可以通过Tabbar配置项指定tab栏的表现，以及tab切换时显示的对应页面。

小程序根目录下的 app.json 文件用来对微信小程序进行全局配置  
在小程序配置文件里面可以设置tabBar属性：

先来个简单案例看下效果

### 接下来挨个看下tabBar配置项下的属性： ###

tabBar配置项属性—color

tabBar配置项属性—selectedColor

tabBar配置项属性—backgroundColor

tabBar配置项属性—position

tabBar配置项属性—borderStyle  
![在这里插入图片描述][20191125104122754.png]  
导航位于顶部时看不到上边框，为看到更清晰的效果，简单做下调整，包括字体颜色，背景色等

tabBar配置项属性—list

![在这里插入图片描述][20191125104135655.png]  
tabBar中的list是一个数组，官方限制配置最少2个、最多5个tab，tab按数组的顺序排序。

tabBar配置项属性—list  
按数组的顺序排序，每个项都是一个对象，其属性值如下：

图片文件夹images  
在list中需要按钮的图片，在小程序图标直接放在与app.json文件同级即可。

然后在里面又建了个icons文件夹，专门用于存放图标

图标文件夹images/icons

tabBar配置项之list属性配置项—iconPath

tabBar配置项之list属性配置项—iconPath  
注意：当 position 为 top 时，不显示 icon

以上便是关于tabBar小程序导航的基础配置，后期可能需要动态设置tabBar例如右上角红色消息数等，这些需要调用小程序API，后续涉及到再进行详细介绍。
