react中使用js防抖校验邮箱

RegisterBindUser.js

	onEmailChange = (e) => {
		e.persist();
		this.setState({
			email: e.target.value
		}, () => {
			this.checkEmail(e.target.value)
		})
	};
	
	checkEmail = (email) => {
		axios.post('/account/check_register_email', {
			email
		}).then(res => {
			if (res.data.has_email_registered) {
				this.setState({
					emailRegistered: true,
					msgOpen: true,
					msg: '此邮箱已注册'
				})
			} else {
				this.setState({
					emailRegistered: false,
					msgOpen: false,
				})
			}
		})
	};

	constructor(props) {
		super(props);
		this.state = {
			msgOpen: false,
			msg: '',
			emailRegistered: false
		};
		this.checkEmail = _.debounce(this.checkEmail, 500)
	}
