微信小程序跳转tabbar不见了,微信小程序tabbar找不到标

问题阐述：

在写微信小程序时需要用到tabBar这个功能，但是在app.json文件中写好pages和tabBar保存刷新编译后，预览页面中没有显示底部tab

"pages": [ "pages/index/index", "pages/todo/todo", "pages/diary/diary", "pages/record/record" ], "window": { "backgroundColor": "#F6F6F6", "backgroundTextStyle": "light", "navigationBarBackgroundColor": "#F6F6F6", "navigationBarTitleText": "demo", "navigationBarTextStyle": "black" }, "tabBar": { "list": [{ "pagePath": "pages/todo/todo", "text": "one" },{ "pagePath": "pages/diary/diary", "text": "two" },{ "pagePath": "pages/record/record", "text": "three" } ]}

问题解决：

1、将pages中的tab页面放到前面，但是index会无法显示，页面直接是tab内容

"pages": [ "pages/todo/todo", "pages/diary/diary", "pages/record/record", "pages/index/index" ],

2、比较好的解决方法是让 tabBar 中包含 index 初始页面这一项

"tabBar": { "list": [{ "pagePath": "pages/index/index", "text": "one" },{ "pagePath": "pages/diary/diary", "text": "two" },{ "pagePath": "pages/record/record", "text": "three" } ]}

这样问题就解决了，再次保存刷新编译，底部成功显示出tabBar
