使用vue实现简单键盘的示例(支持移动端和pc端)

Keyboard.vue



<script>
import clickoutside from '../directives/clickoutside'

export default {
 directives: { clickoutside },
 data() {
 return {
  keyList: [],
  status: 0,//0 小写 1 大写 2 数字 3 符号
  lowercase: [
  ['q', 'w', 'e', 'r', 't', 'y', 'u', 'i', 'o', 'p'],
  ['a', 's', 'd', 'f', 'g', 'h', 'j', 'k', 'l'],
  ['top', 'z', 'x', 'c', 'v', 'b', 'n', 'm', 'del'],
  ['123', 'point', 'blank', 'symbol', 'enter']
  ],
  uppercase: [
  ['Q', 'W', 'E', 'R', 'T', 'Y', 'U', 'I', 'O', 'P'],
  ['A', 'S', 'D', 'F', 'G', 'H', 'J', 'K', 'L'],
  ['top', 'Z', 'X', 'C', 'V', 'B', 'N', 'M', 'del'],
  ['123', 'point', 'blank', 'symbol', 'enter']
  ],
  equip:!!navigator.userAgent.toLocaleLowerCase().match(/ipad|mobile/i)//是否是移动设备
 }
 },
 props: {
 option: {
  type: Object
 }
 },
 computed: {
 showKeyboard(){
  return this.option.show
 }
 },

 mounted() {
 this.keyList = this.lowercase
 },

 methods: {
 tabHandle({ value = '' }) {
  if(value.indexOf('tab-num') > -1){
   this.status = 2
   //数字键盘数据
  }else if(value.indexOf('key-delete') > -1){
  this.emitValue('delete')
  }else if(value.indexOf('tab-blank') > -1){
  this.emitValue(' ')
  }else if(value.indexOf('tab-enter') > -1){
  this.emitValue('\n')
  }else if(value.indexOf('tab-point') > -1){
  this.emitValue('.')
  }else if(value.indexOf('tab-symbol') > -1){
  this.status = 3
  }else if(value.indexOf('tab-top') > -1){
  if(this.status === 0){
   this.status = 1
   this.keyList = this.uppercase
  }else{
   this.status = 0
   this.keyList = this.lowercase
  }
  }else{

  }
 },

 clickKey(event) {
  if(event.type === 'click' && this.equip) return
  let value = event.srcElement.innerText
  value && value !== '符' && value !== '·' && value !== '123'? this.emitValue(value) : this.tabHandle(event.srcElement.classList)
 },

 emitValue(key) {
  this.$emit('keyVal', key)
 },

 closeModal(e) {
  if (e.target !== this.option.sourceDom) {
  // this.showKeyboard = false
  this.$emit('close', false)
  }
 }
 }
}
</script>

KeyInput.vue


<script>
import Keyboard from '../components/Keyboard'
export default {
 components: {
 Keyboard
 },
 data() {
 return {
  option: {
  show: false,
  sourceDom: ''
  },
  inputValue: ''
 }
 },
 props: {},
 created() {},
 methods: {
 getInputValue(val) {
  if(val === 'delete'){
  this.inputValue = this.inputValue.slice(0,this.inputValue.length -1)
  }else{
  this.inputValue += val
  }
 },
 onFocus() {
  this.$set(this.option, 'show', true)
  this.$set(this.option, 'sourceDom', this.$refs['keyboard'])
 },
 //获取光标位置
 getCursorPosition() {
  let doc = this.$refs['keyboard']
  if (doc.selectionStart) return doc.selectionStart
  return -1
 },
 //设置光标位置 暂未实现
 setCursorPosition(pos) {
  let doc = this.$refs['keyboard']
  console.log(doc.setSelectionRange)
  doc.focus()
  doc.setSelectionRange(1,3)
 }
 }
}
</script>

使用demo


<script>
import KeyInput from '../components/KeyInput'
export default {
 components: {
 KeyInput
 },
 data() {
 return {
 }
 },
 created() {},
 methods: {
 }
}
</script>
