|

- `:xxx=yyy`, 属性绑定, 类似`vue`,在属性前加上`:`, 该属性不再使用`setAttribute()`, 而是直接赋值, 可满足你需要传递复杂数据结构的需求。
|
||||
- `#animation={type}`, 开箱即用的动画配置, 内置6种动画`fade(默认), scale, bounce, micro-bounce, rotate, slide`
|
||||
- `ref=xxx`, 类似`vue`的节点标识, 可方便的在`mounted()`之后通过 `this.$refs.xxx` 来访问该节点
|
||||
- 内置特色的双向绑定方法`live()`
|
||||
- 用内置的`bind()`方法来给当前组件绑定事件时, 组件移除时事件也会自动销毁,无需手动销毁。
|
||||
- 灵活的`props`定义
