React验证码组件实现

最近一直在写bug和改bug的死循环过程
总结一下自己修改的一个验证码组件

原生实现输入框 代码

import React from 'react'

class AutotabInput extends PureComponent {
    constructor(props) {
        super(props)

        this.handleChange = this.handleChange.bind(this)
        this.handleTab = this.handleTab.bind(this)
        this.handleDelete = this.handleDelete.bind(this)
    }

    handleChange(e) {
        const input = e.target.value
        if (this.props.onChange) {
            this.props.onChange(input)
        }
        this.handleTab(e)
    }

    handleDelete(e) {
        const BACK_SPACE = 8
        const isBackSpaceKey = e.keyCode === BACK_SPACE
        if (isBackSpaceKey && e.target.value.length === 0) {
            let previous = e.target
            previous = previous.previousElementSibling
            while (previous) {
                if (previous === null) break
                if (previous.tagName.toLowerCase() === 'input') {
                    previous.focus()
                    break
                }
            }
        }
    }

    handlePaste(e){
        let clipboardData = e.clipboardData || window.clipboardData;
        if(clipboardData){
            let clipdata=clipboardData.getData('Text')
            return this.props.handlePaste(clipdata)
        }
    }

    handleTab(e) {
        const target = e.target
        const input = target.value
        if (input.length >= this.props.maxLength) {
            let next = target
            next = next.nextElementSibling
            while (next) {
                if (next === null) break
                if (next.tagName.toLowerCase() === 'input') {
                    next.focus()
                    break
                }
            }
        }
    }

    render() {
        return (
            <input
                type={this.props.type}
                name={this.props.name}
                placeholder={this.props.hint}
                maxLength={this.props.maxLength}
                // defaultValue={this.props.value}
                onChange={this.handleChange}
                onKeyDown={this.props.maxLength ? this.handleDelete : null}
                style={this.props.style}
                autoFocus={this.props.autoFocus}
                value={this.props.value}
                ref={c => (this._input = c)}
                onPaste={(e)=>{this.handlePaste(e)}}
            />
        )
    }
}

export default AutotabInput
