这样设置微信小程序没有返回键

{"path": "pages/index/index","style": {"navigationBarTitleText": "首页","app-plus": {"titleNView": false, //禁用原生导航栏 也就是去掉导航"scrollIndicator": "none"}}},

这样设置微信小程序有返回键

{"path": "pages/index/index","style": {"navigationBarTitleText": "首页","app-plus": {//#ifdef H5"titleNView": false  //这样就有返回键微信小程序，只在H5去掉顶部导航栏，条件编译，只在H5编译//#ifdef H5//#endif}}},
