基于vue3.0和element-plus的IP地址输入框

<template>
  <div class="my_ip_address_input">
    <template v-for="index in indexes" :key="index">
      <el-input  v-model="ipAddress[index]"
                @keyup="handleChange"
                oninput="value=value.replace(/[^\d]/g,'')&&value>255?255:value"/>
      <span v-if="index!==3">.</span>
    </template>
  </div>
</template>

<script>
import {defineComponent, ref} from "vue";
const indexes=[0,1,2,3]
export default defineComponent({
  name: "MyIpAddressInput",
  props: {
    value: {
      type: String,
      default: ""
    }
  },
  setup(props,ctx) {
    const ipAddress = ref([])
    ipAddress.value = props.value.split(".")
    const handleChange = () => {
      console.log(ipAddress.value.join("."))
      ctx.emit("update:value",ipAddress.value.join("."))
    }
    return {
      ipAddress,
      handleChange,
      indexes
    }
  }
})
</script>
