检查电子邮件是否在json对象中

function isEmailInJSONObject(jsonObject) {
  for (var key in jsonObject) {
    if (typeof jsonObject[key] === 'object') {
      // 递归遍历嵌套的JSON对象
      if (isEmailInJSONObject(jsonObject[key])) {
        return true;
      }
    } else if (typeof jsonObject[key] === 'string') {
      // 验证电子邮件地址
      var emailRegex = /\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/;
      if (emailRegex.test(jsonObject[key])) {
        return true;
      }
    }
  }
  
  return false;
}

// 示例用法
var json = {
  "name": "John Doe",
  "email": "john.doe@example.com",
  "address": {
    "street": "123 ABC Street",
    "city": "XYZ",
    "email": "another.email@example.com"
  }
};

var isEmailPresent = isEmailInJSONObject(json);
console.log(isEmailPresent); // 输出 true
