arrays - 从嵌套数组 JSON 访问单个数据

问题描述

我正在尝试使用 URL ' https://123.abc.com/student ' 从 JSON 文件访问单个数据。我需要显示来自该 URL 的单个数据。有人可以帮我解决这个问题吗？

我的 Json 数据看起来像这样

{"students":[{"_id":"5dc516e51bdd2c0014e32e65","name":"John","email":"john@gmail.com","mobile":"9988776655","__v":0},{"_id":"5dc517b51bdd2c0014e32e69","name":"Mark","email":"mark@gmail.com","mobile":"9834783927","__v":0},{"_id":"5dca9231cfba5c0014d3d765","name":"Glen","email":"glen@gmail.com","mobile":"9996474563","__v":0},{"_id":"5dcb898b9327cb00142169bb","name":"vijay","email":"vijay@gmail.com","mobile":"9884699633","__v":0},{"_id":"5dcb89c09327cb00142169bc","name":"tests","email":"test@gmail.com","mobile":"9887456123","__v":0},{"_id":"5dcb8caa9327cb00142169bd","name":"greens","email":"greens@gmail.com","mobile":"9876543210","__v":0},{"_id":"5dcb95d69327cb00142169be","name":"Akash","email":"a4akash6@gmail.com","mobile":"9846042118","__v":0},{"_id":"5dcb961c9327cb00142169bf","name":"Akash K M","email":"Akash.Madhu@cognizant.com","mobile":"9846042118","__v":0},{"_id":"5dcce611ad69f500149660d5","name":"efavewbvwevb","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0},{"_id":"5dcce874ad69f500149660d6","name":"efavewbvwevb","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0},{"_id":"5dcce968ad69f500149660d7","name":"indrajit","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0}]}

解决方案

你可以用这个

let data = {"students":[{"_id":"5dc516e51bdd2c0014e32e65","name":"John","email":"john@gmail.com","mobile":"9988776655","__v":0},{"_id":"5dc517b51bdd2c0014e32e69","name":"Mark","email":"mark@gmail.com","mobile":"9834783927","__v":0},{"_id":"5dca9231cfba5c0014d3d765","name":"Glen","email":"glen@gmail.com","mobile":"9996474563","__v":0},{"_id":"5dcb898b9327cb00142169bb","name":"vijay","email":"vijay@gmail.com","mobile":"9884699633","__v":0},{"_id":"5dcb89c09327cb00142169bc","name":"tests","email":"test@gmail.com","mobile":"9887456123","__v":0},{"_id":"5dcb8caa9327cb00142169bd","name":"greens","email":"greens@gmail.com","mobile":"9876543210","__v":0},{"_id":"5dcb95d69327cb00142169be","name":"Akash","email":"a4akash6@gmail.com","mobile":"9846042118","__v":0},{"_id":"5dcb961c9327cb00142169bf","name":"Akash K M","email":"Akash.Madhu@cognizant.com","mobile":"9846042118","__v":0},{"_id":"5dcce611ad69f500149660d5","name":"efavewbvwevb","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0},{"_id":"5dcce874ad69f500149660d6","name":"efavewbvwevb","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0},{"_id":"5dcce968ad69f500149660d7","name":"indrajit","email":"indrajitrakurajravi@gmail.com","mobile":"9042758563","__v":0}]}

let result = data.students.forEach(val=>{
  console.log(val)
  // let data individually as 
  let name = val.name 
  let email = val.email 
})
