使用vue实现简单键盘的示例(支持移动端和pc端)(2)

<template>
 <div>
 <input type="text" ref="keyboard" v-model="inputValue" @focus="onFocus">
 <Keyboard :option="option" @keyVal="getInputValue" @close="option.show = false"></Keyboard>
 </div>
</template>
<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>
<style lang="less" scoped>

</style>

<template>
 <div>
 <key-input class="demo-class"></key-input>
 </div>
</template>
<script>
import KeyInput from '../components/KeyInput'
export default {
 components: {
 KeyInput
