my.switchTab

Introduction

Jump to the specified tabBar page, and then close all other pages that are not tabBar.

If the Mini Program has multiple tabs, you can use tabBar to configure the behavior of the specified tab, and the page to display during the tab switchover (You can switch tabs at the bottom of the client window).

Note: You can jump to the page via page jumping (my.navigateTo) or page redirecting (my.redirectTo) . Even the page is defined in the tabBar configuration, the bottom tab bar is not displayed. In addition, the first page of the tabBar must be the homepage.

Sample Code

copy

// app.json
{
  "tabBar": {
    "items": [{
      "pagePath": "page/home/index",
      "name": "Home"
    },{
      "pagePath": "page/user/index",
      "name": "User"
    }]
  }
}
