子组件传图片路径imgUrl值给父组件，父组件传imgaddr值给子组件
子组件：
export default class Son extends React.Component {
//获取父组件传过来的imgaddr值
constructor(props) {
super(props);
this.state = {
imgaddr:props.imgaddr,
};}
//通过回调函数传值给父组件
onSuccess=(res, dataUrl)=> {
this.refs.targetViewer.src = dataUrl;
this.props.getImg(res.data.imgurl);
};
//通过this.props.imgaddr绑定父组件传过来的值
render() {
return (
<div>
<img
src={this.props.imgaddr}
/>
</div>
}
}
父组件：
export default class Father extends Component {
constructor(props) {
super(props);
this.state = {
imgurl:'',
};}
//通过getImg方法取到子组件传过来的imgurl值
getImg = (imgurl) => {
this.setState({
imgurl:imgurl
});
};
//父组件通过record传imgaddr值给子组件
render: (value, index, record) => {
return (
<EditDialog
record={record}
/>
);
},
//在组件CropUploadImage中绑定imgurl值
<CropUploadImage
getImg={this.getImg}
/>
}
