### 使用单独的Tree包
#### 组件引入
先进行下载Tree包
```
npm install --save bee-tree
```
组件调用
```js
2018-01-25 18:13:15 +08:00
import Tree from 'bee-tree';
2016-12-30 15:43:08 +08:00
2016-12-30 15:48:50 +08:00
const TreeNode = Tree.TreeNode;
2016-12-30 15:43:08 +08:00
2016-12-30 15:48:50 +08:00
const defaultProps = {
keys: ['0-0-0', '0-0-1']
}
class Demo1 extends Component {
constructor(props) {
super(props);
const keys = this.props.keys;
this.state = {
defaultExpandedKeys: keys,
defaultSelectedKeys: keys,
defaultCheckedKeys: keys,
};
}
onSelect(info) {
console.log('selected', info);
}
onCheck(info) {
console.log('onCheck', info);
}
render() {
return (
< Tree className = "myCls" showLine checkable
defaultExpandedKeys={this.state.defaultExpandedKeys}
defaultSelectedKeys={this.state.defaultSelectedKeys}
defaultCheckedKeys={this.state.defaultCheckedKeys}
onSelect={this.onSelect} onCheck={this.onCheck}
>
< TreeNode title = "parent 1" key = "0-0" >
< TreeNode title = "parent 1-0" key = "0-0-0" disabled >
< TreeNode title = "leaf" key = "0-0-0-0" disableCheckbox / >
< TreeNode title = "leaf" key = "0-0-0-1" / >
< / TreeNode >
< TreeNode title = "parent 1-1" key = "0-0-1" >
< TreeNode title = {<span style = {{ color: ' # 08c ' } } > sss< / span > } key="0-0-1-0" />
< / TreeNode >
< / TreeNode >
< / Tree >
);
}
}
2016-12-30 15:43:08 +08:00
2016-12-30 15:48:50 +08:00
React.render(< Demo1 / > , document.getElementById('target'));
```
#### 样式引入
- 可以使用link引入dist目录下tree.css
```
< link rel = "stylesheet" href = "./node_modules/build/bee-tree.css" >
2016-12-30 15:43:08 +08:00
```
2016-12-30 15:48:50 +08:00
- 可以在js中import样式
```js
import "./node_modules/src/Tree.scss"
//或是
import "./node_modules/build/bee-tree.css"
```
