## 生命周期的方法
### Create
When a component is created, it receives properties from its parent component as well as a `ComponentLink`. The properties can be used to initialize the component's state and the "link" can be used to register callbacks or send messages to the component.
當一個元件被建立,他會接收從父元件,也就是 `ComponentLink` ,傳下來的屬性。 這些屬性用來初始化元件的狀態此外「link」可以用來註冊回調函式或傳訊息給元件。
It is common to store the props and the link in your component struct, like so:
通常,你的元件 struct 會儲存 props 與 link就像下面的例子
```rust
pub struct MyComponent {

### View
Components declare their layout in the `view()` method. Yew provides the `html!` macro for declaring HTML and SVG nodes and their listeners as well as child components. The macro acts a lot like React's JSX, but uses Rust expressions instead of JavaScript.
元件會在 `view()` 方法中宣告佈局。Yew 提供 `html!` 巨集來宣告 HTML 合 SVG 的結點,包含他們的監聽事件與子結點。這個巨集扮演像是 React 的 JSX 的角色,但是是使用 Rust 的表達式,而不是 JavaScript 的。

impl Component for MyComponent {

For usage details, check out the `html!` guide:
更多使用細節,請參考 `html!` 教學:
{% page-ref page="../html/" %}
### Mounted
The `mounted()` component lifecycle method is called after `view()` is processed and Yew has mounted your component to the DOM but before the browser refreshes the page. A component may wish to implement this method to perform actions that can only be done after the component has rendered elements. If you wish to re-render your component after making changes `mounted()`, return `true`.
`mounted()` 生命周期的方法,會在 `view()` 方法結束後被呼叫此時Yew 已經掛載你的元件到 DOM 上,但是在瀏覽器還未刷新頁面。 實作這個方法,可以執行,希望在元件渲染完的元素之後,才能做的動作。如果結束 `mounted()` 的改變後,你希望重新渲染你的元件,請回傳 `true`
```rust
use stdweb::web::html_element::InputElement;

Note that this lifecycle method does not require an implementation and will do nothing by default
注意,這個生命周期方法,不是一定要被實作,預設的行為是不做任何事情。
