### Common Patterns

**Example 1** (javascript):

```javascript
WeixinJSBridge.invoke('imagePreview', {
    current: 'http://inews.gtimg.com/newsapp_bt/0/1693121381/641',
    urls: [ // 所有图片的URL列表，数组格式
        'https://img1.gtimg.com/10/1048/104857/10485731_980x1200_0.jpg',
        'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
        'https://img1.gtimg.com/10/1048/104857/10485729_980x1200_0.jpg'
    ]
}, function(res) {
    console.log(res.err_msg)
})
```

**Example 2** (javascript):

```javascript
wx.previewImage({
  current: 'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
  urls: [ // 所有图片的URL列表，数组格式
    'https://img1.gtimg.com/10/1048/104857/10485731_980x1200_0.jpg',
    'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
    'https://img1.gtimg.com/10/1048/104857/10485729_980x1200_0.jpg'
  ],
  success: function(res) {
    console.log(res)
  }
})
```

## Reference Files

This skill includes comprehensive documentation in `references/`:

- **getting_started.md** - Quick start and introduction
- **framework.md** - Mini Program framework (逻辑层、视图层)
- **components.md** - Built-in components
- **api.md** - API reference
- **cloud.md** - Cloud development (云开发)
- **reference.md** - Configuration reference

Use `view` to read specific reference files when detailed information is needed.

## Key Concepts

### App Lifecycle

```javascript
App({
  onLaunch(options) {
    // Mini Program initialized
  },
  onShow(options) {
    // Mini Program shown
  },
  onHide() {
    // Mini Program hidden
  },
  globalData: {
    userInfo: null
  }
})
```

### Page Lifecycle

```javascript
Page({
  data: {
    message: 'Hello World'
  },
  onLoad(options) {
    // Page loaded
  },
  onShow() {
    // Page shown
  },
  onReady() {
    // Page ready
  },
  onHide() {
    // Page hidden
  },
  onUnload() {
    // Page unloaded
  }
})
```

### WXML Data Binding

```wxml
<view>{{message}}</view>
<view wx:if="{{condition}}">Conditional</view>
<view wx:for="{{array}}" wx:key="id">{{item}}</view>
```

### Event Handling

```wxml
<button bindtap="handleTap">Click Me</button>
```

```javascript
Page({
  handleTap(e) {
    console.log(e)
  }
})
```
