How to display tabbar in uniapp :

First, check the official website to learn about tabBar

If the application is a multi-tab application, you can specify the performance of the tab bar through the tabBar configuration item, and the corresponding page displayed when tab switching .

  • When the position is set to top, the icon will not be displayed

  • The list in tabBar is an array and can only be configured with at least 2 , up to 5 tabs, and the tabs are sorted in the order of the array.

  • tabbar may not be rendered in time when switching the first load. You can first load it in the onLoad life cycle of each tabbar page. Pop up a waiting snowflake (hello uni-app uses this method)

  • The tabbar page is displayed once and remains in the memory. Switching the tabbar page again will only trigger each page. onShow will no longer trigger onLoad.

  • The tabbar at the top is currently only supported on the WeChat applet. If you need to use the top tab, it is recommended not to use the top setting of the tabbar, but To make the top tab yourself, you can refer to hello uni-app->Template->Top tab.

Second, configure it in the page.js file

{
"pages": [ //pages数组中第一项表示应用启动页,
{
"path": "pages/index/index",
"style": {
"navigationBarTitleText": "uni-app"
}
}
    ,{
            "path" : "pages/show/show",
            "style" : {
"navigationBarTitleText": "show"
}
        }
        ,{
            "path" : "pages/component/component",
            "style" : {
"navigationBarTitleText": "component"
}
        }
    ],
"globalStyle": {
"navigationBarTextStyle": "black",
"navigationBarTitleText": "uni-app",
"navigationBarBackgroundColor": "#F8F8F8",
"backgroundColor": "#F8F8F8"
},
"tabBar": {
    "color": "#F0AD4E",
    "selectedColor": "#3cc51f",
    "borderStyle": "black",
    "backgroundColor": "#F8F8F8",
    "list": [{
        "pagePath": "pages/index/index",
        "iconPath": "static/logo.png",
        "selectedIconPath": "static/logo.png",
        "text": "首页"
    },{
        "pagePath": "pages/component/component",
        "iconPath": "static/logo.png",
        "selectedIconPath": "static/logo.png",
        "text": "组件"
    }, {
        "pagePath": "pages/show/show",
      "iconPath": "static/logo.png",
      "selectedIconPath": "static/logo.png",
        "text": "展示"
    }]
} 
}

At first I didn’t know why it was not displayed when I configured two pages in "tabBar", but it was successful after configuring three pages. I don’t know if you have encountered this problem.

Okay, the configuration is successful. , the renderings are as follows
