selectItem(item, index) {
this.setState({
selectName: item.skill_name
})
this.props.getChildrenMsg(item.skill_name)
this.props.callBack()
}
父组件B代码如下：
import A from "../components/A"; //父组件引入子组件
getChildrenMsg(item) {
this.setState({
selectName: item, //传递的值 ， setState赋值
});
}
<A getChildrenMsg={this.getChildrenMsg.bind(this)}
/>
