## Onclick事件属性
单击元素时会触发事件。
它就像_onclick方法_或`addEventListener('click')` 。
```html
<element onclick="event"></element>
```
> `event`可以是JavaScript函数也可以编写原始JavaScript
### 例子
单击时更改`<p>`元素的颜色
```html
<p id="text" onclick="redify()">Change my color</p>
<script>
function redify(){
let text = document.querySelector('#text');
text.style.color = "red";
}
</script>
```
使用原始JavaScript onclick属性
```html
<button onclick="alert('Hello')">Hello World</button>
```
