1.首先安装vue  国际化电话组件

npm install el-phone-number-input;

 2.当前页面引入组件

import { ElPhoneNumberInput, mobileValidator, phoneNumberValidator} from 'el-phone-number-input'

 3.下面是具体使用代码：callingCode是国家区号，phoneNumber是手机号

import { ElPhoneNumberInput, mobileValidator, phoneNumberValidator} from 'el-phone-number-input'

export default {
    components: {
	      ElPhoneNumberInput
	},
	data(){
	    return{
           phone: {
              callingCode: '',
              phoneNumber: ''
           },
        }
    }
}

/* 使用方法 表单 */
<el-form-item label="Phone" prop="phone">
        <el-phone-number-input v-model="phone"   ></el-phone-number-input>
</el-form-item>
