一个简单的车牌输入组件（vue）

event事件：

export let life = {
     created () {
       // this.currentPlate = this.plateNumber    // console.log(this.plateNumber)    // this.EnterPlateNumber.input.firstWord = this.plateNumber.slice(0,1)    // this.EnterPlateNumber.input.secondWord = this.plateNumber.slice(1,2)    // this.EnterPlateNumber.input.lastWords = this.plateNumber.slice(2,9)  }}export let event = {
     clickInput (type) {
       this.methods('clickInput',type)  },  clickKeyboard (val) {
       if (this.plateInput.input.type === 'p2' && parseInt(val) >= 0 && parseInt(val) <= 9) return    this.methods('clickKeyboard', val)    this.methods('setPlateNumber')    this.methods('setDirectIssuedPlateNumber')  },  //删除车牌  clickDelete () {
       this.methods('clickDelete')    this.methods('setPlateNumber')    this.methods('setDirectIssuedPlateNumber')  },  hiddenKeybord(){
       this.methods('hiddenKeybord')  },  enterWord(){
       this.methods('enterWord')  }}export let watch = {
   }

methods方法：

export default class {
     clickInput(type){
       this.plateInput.input.type = type    this.plateInput.input.dialogVisible = true  }  hiddenKeybord(){
       this.plateInput.input.dialogVisible = false  }  enterWord(){
       this.plateInput.input.dialogVisible = false  }  clickKeyboard (val) {
       this.plateInput.input.value[this.plateInput.input.type] = val    let type = this.plateInput.input.type.split('p')[1]    if (type !== '8') {
         this.plateInput.input.type = 'p' + (parseInt(type) + 1)    }  }  clickDelete () {
       this.plateInput.input.value[this.plateInput.input.type] = undefined    let nu = this.plateInput.input.type.split('p')[1]-1    if(nu>=0){
         this.plateInput.input.value['p'+nu] = undefined    }    let type = this.plateInput.input.type.split('p')[1]    if (type !== '1') {
         this.plateInput.input.type = 'p' + (parseInt(type) - 1)    }  }  setPlateNumber () {
       if (this.plateInput.input.plateNumber) {
         this.plateNumber1 = this.plateInput.input.plateNumber    }else{
         this.plateNumber1 = undefined    }  }  setDirectIssuedPlateNumber () {
       if (this.plateInput.input.plateNumber) {
         this.plateNumber1 = this.plateInput.input.plateNumber    }else{
         this.plateNumber1 = undefined    }  }}

model数据：

export let props = ['name','plateNumber','noRightPart']export let model = {
     currentPlate:undefined,  plateInput:{
       input:{
         value:{
           p1:'桂',        p2:'B',        p3:2,        p4:2,        p5:2,        p6:2,        p7:2,        p8:0      },      type:'p1',      dialogVisible:false    }  },  Keyboard: {
       province: ['京', '津', '冀', '晋', '蒙', '辽', '吉', '黑', '沪', '苏', '浙', '皖', '闽', '赣', '鲁', '豫', '鄂', '湘', '粤', '桂', '琼', '渝', '川', '贵', '云', '藏', '陕', '甘', '青','宁','新','台','港','澳','使','领','警','学'],    number: ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C','D', 'E', 'F', 'G','H', 'J', 'K', 'L', 'M', 'N', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '学', '港', '澳']  },}export let computed = {
     plateNumber1 : {
       get () {
         return this.plateNumber||''    },    set (val) {
         this.$emit('update:plateNumber', val)    }  }}

因为这里用了独家的框架，所以根据需要把相应的生命周期函数放到正常的vue项目的位置，把event就写成正常的函数，methods就是i正常的methods里面的方法，model就是data里return的数据
