常见问题及解决方案

  1. 本地缓存storage,类似localStorage,可以存取改删 String/Object

  2. 页面跳转及传值

<navigator url="../detail/detail?name={{item.name}}"></navigator>
  1. 跨页面通信,发现一个方案是:https:/danneyyang/weapp-event

  2. 组件化

   如模版:header.wxml <template name="header"> <view class="page-header"> <text class="page-header-text">{{title}}</text> <view class="page-header-line"></view> </view> </template>    如何使用? ```

 <template is="header" data="{{title: 'start/stopRecord、play/pause/stopVoice'}}"/>

```
  1. 如何请求http数据?

    方法:开发者工具-点击项目-勾选开发环境不校验请求域名及TLS版本;  

  2. Page 内部方法如何调用?方法:this.fn(),例如:


fn:function () {
  console.log("fn");
},
onReady: function () {
   var that = this;
   //that = this;
   that.fn();
} 

  1. 底部tabBar菜单栏显示不出来   解决方法:pages先后顺序配置正确,依次是第一个tabBar的路径,第二个tabBar的路径。。app页面的路径,例如:
{
  "pages":[ 
    "pages/week/index",
    "pages/mine/index",
    "pages/index/index"
  ],
  "window":{
    "backgroundTextStyle":"light",
    "navigationBarBackgroundColor": "#FC3D39",
    "navigationBarTitleText": "title",
    "navigationBarTextStyle":"white"
  },
  "tabBar": {
    "color": "#9a9a9a",
    "selectedColor": "#FC3D39",
    "borderStyle": "black",
    "backgroundColor": "#ffffff",
    "list": [{
      "pagePath": "pages/week/index",
      "iconPath": "image/calendar.png",
      "selectedIconPath": "image/calendar2.png",
      "text": "first"
    }, {
      "pagePath": "pages/mine/index",
      "iconPath": "image/mine.png",
      "selectedIconPath": "image/mine2.png",
      "text": "second"
    }]
  }
}
