微信小程序自定义tabBar,中间突出

 

 1、app.json里

"tabBar": {
    "custom": true,
    "color": "#000",
    "selectedColor": "#ff6861",
    "borderStyle": "black",
    "backgroundColor": "#fff",
    "list": [
      {
        "pagePath": "pages/index/index",
        "text": "首页",
        "iconPath": "/images/home.png",
        "selectedIconPath": "/images/select-home.png"
      },
      {
        "pagePath": "pages/pub/index",
        "text": "发布"
      },
      {
        "pagePath": "pages/mine/index",
        "text": "我",
        "iconPath": "/images/my.png",
        "selectedIconPath": "/images/select-my.png"
      }
    ]
  },

app.js里存储菜单选中的是哪一个

 globalData: {
    selected: 0
  }

2、最外层定义tabBar组件

3、自定义菜单栏组件样式

custom-tab-bar/index.wxml文件代码如下

  
  
    
    
    {{item.text}}
    
    +
  

 

custom-tab-bar/index.json文件代码如下

{
  "component": true
}

custom-tab-bar/index.js文件代码如下

var app = getApp()
Component({
  data: {
    selected: 0,
    color: "#ccc",
    selectedColor: "#1296db",
    list: [{
        pagePath: "/pages/index/index",
        iconPath: "/images/home.png",
        text: "首页",
        selectedIconPath: "/images/select-home.png",
        id: 0
      },
      {
        pagePath: "/pages/ pub/index",
        text: "发布",
        id: 1
      },
      {
        pagePath: "/pages/mine/index",
        iconPath: "/images/my.png",
        text: "我",
        selectedIconPath: "/images/select-my.png",
        id: 2
      }
    ]
  },
  ready: function () {
    this.setData({
      selected: app.globalData.selected
    })
  },
  methods: {
    switchTab(e) {
      const data = e.currentTarget.dataset;
      const url = data.path;
      app.globalData.selected = data.index;
      if(data.index===1){
        wx.navigateTo({
          url: '/pages/publish/index'
        })
      }else{
        wx.switchTab({
          url: url
        })
      }
    }
  }
})

}

  justify-content: center;
  align-items: center;
  flex-direction: column;
}
