Use the jquery.validate custom method to implement the logical verification of 'fill in at least one mobile number or landline number'_jquery

In recent project development, we have encountered the requirement of "fill in at least one mobile phone number or landline number", as shown in the figure below:

The jquery.validate.js verification component used in the project currently does not support this kind of "or" logic verification, so I defined one myself

jQuery.validator.addMethod("phone", function(value, element) {
      var mobile = $("#mobile").val();// 手机号码
      var telephone = $("#telephone").val();// 固定电话
      var mobileRule = /^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0-9]|170)\d{8}$/;
      var telephoneRule = /^\d{3,4}-?\d{7,9}$/;

      // 都没填
      if (isEmpty(mobile) && isEmpty(telephone)) {
        //自定义错误提示
        $("#receivingMobile_tip").addClass("errorHint").text("请填写固定电话或手机号码");
        return false;
      }
      var mobilePass = false;
      var telephonePass = false;
      // 手机填了、固定电话没填
      if (!isEmpty(mobile) && isEmpty(telephone)) {
        if (!mobileRule.test(mobile)) {
          //自定义错误提示
          $("#receivingMobilePhone_tip").removeClass("successHint").addClass("errorHint").text("手机号码格式不对");
          return false;
        } else {
          mobilePass = true;
        }
      }

      // 手机没填、固定电话填了
      if (isEmpty(mobile) && !isEmpty(telephone)) {
        if (!telephoneRule.test(telephone)) {
          //自定义错误提示
          $("#receivingTelephone_tip").removeClass("successHint").addClass("errorHint").text("固定电话格式不对");
          return false;
        } else {
          telephonePass = true;
        }
      }

      if (mobilePass || telephonePass) {
        //自定义成功提示
        $("#receivingTelephone_tip").removeClass("errorHint").addClass("successHint").text('');
        return true;
      } else {
        return false;
      }
    }, "ignore");

Supplement isEmpty function:

 // 空字符串判断
function isEmpty(v, allowBlank) {
   return v === null || v === undefined || (!allowBlank ? v === "" : false);
}

Handling errorPlacement of validate:

errorPlacement : function(error, element) {
        //忽略自定义的方法错误提示
        if (error.text() == "ignore") {
          return;
        }
　　　　　　　　　
      }

Use

in rules

rules : {
        telephone : {
          phone : []
        },
        mobile : {
          phone : []
        }
      }
