react-cropper VS react-easy-crop

Reactjs Try create upload function with cropper component. But when I try set state it says that Uncaught TypeError: this.setState is not a function at FileReader.reader.onload Component import React, { Component, PropTypes } from 'react'import { Link, browserHistory } from 'react-router'import { connect } from 'react-redux'import Cropper from 'react-cropper';class HeadPortrait extends Component { constructor(props) { super(props) this.state = { image: '', } } clickadd(e) { document.getElementById('uploadfiles').click(); } loadFile(e) { e.preventDefault(); var reader = new FileReader(); reader.onload = function () { this.setState({ image: reader.result }) }; reader.readAsDataURL(e.target.files[0]); ; }; _crop() { // image in dataUrl console.log(this.refs.cropper.getCroppedCanvas().toDataURL()); } render() { return ( Add Image Save ) }}function mapStateToProps(state) { return { // stories: state.stories }}export default connect(mapStateToProps)(HeadPortrait) Trying do like in example https://github.com/roadmanfong/react-cropper/blob/master/example/src/Demo.jsx Answer link : https://codehunter.cc/a/reactjs/this-setstate-is-not-a-function-trying-upload-image-reactjs

Idk what tech OP used, but if you're working on React this is literally just react-easy-crop out of the box. https://www.npmjs.com/package/react-easy-crop

Once a user selects an image, he can modify the image(crop, zoom, rotate) via react-easy-crop library.
