Vue elementUI el-input输入框手机号校验

1.限制input框内只能输入数字，且为11位

 type="number"    // 数字类型

 // maxlength属性对type="number"类型的输入框无效
οninput="if(value.length>11)value=value.slice(0,11)" 

 2.对输入手机号做校验 

   <el-form :model="dialogData" :rules="addAddressRules" ref="dialogData">
        <el-form-item label="" prop="phone">
          <el-input
            placeholder="请输入电话号码"
            v-model="dialogData.phone"
            type="number"
            oninput="if(value.length>11)value=value.slice(0,11)"
            onkeyup="this.value = this.value.replace(/[^\d]/g,'');"
            size="large"
            clearable
          >
          </el-input>
        </el-form-item>
   </el-form>

data() {
    var checkPhone = (rule, value, callback) => { // 手机号验证
      if (!value) {
        return callback(new Error('手机号不能为空'));
      } else {
        const reg = /^1[3456789]\d{9}$/
        if (reg.test(value)) {
          callback();
        } else {
          return callback(new Error('请输入正确的手机号'));
        }
      }
    };
    return {  
      dialogData: {
        phone:'',
      },   
      addAddressRules: {
        phone: [
          { required: true, message: "请输入正确手机号", trigger: "blur" },
          {validator: checkPhone, trigger: 'blur'}
        ],
      },
    }
  },
