 const keys = () => [1, 2, 3, 4, 5, 6, 7, 8, 9, '', 0]
 // let sendFlag = true // 防止重复发送密码
 export default {
 data () {
 return {
 items: [0, 1, 2, 3, 4, 5],
 keys: keys(),
 password: []
 }
 },
 methods: {
 backHandle () {
 this.clearPasswordHandle() // 返回时清除password
 this.$emit('backFnc') // 返回上级
 },
 keyUpHandle (e) {
 let text = e.currentTarget.innerText
 let len = this.password.length
 if (!text || len >= 6) return
 this.password.push(text)
 this.ajaxData()
 },
 delHandle () {
 if (this.password.length <= 0) return false
 this.password.shift()
 },
 ajaxData () {
 if (this.password.length >= 6) {
 console.log(parseInt(this.password.join(' ').replace(/\s/g, '')))
