array.map 不是函数[关闭]

Question

我不断收到此错误 escalationreport.js:62 Uncaught (in promise) TypeError: results.map is not a function

{escalated_by: "Osten Diniz", ticket_Number: "SHA-194414", escalation_reason: "Closing sale", date: "2020-03-31T16:25:30.000Z"}

这是浏览器级别的控制台日志

我正在尝试将这些值映射到一个表，但由于上述错误而失败

我发现 data.map 仅适用于数组，但不知道如何将该 json 转换为数组（{} 到 []）

Answer 1

您可以使用Object.keys() 或Object.entries()，然后使用map

Object.entries(yourObject).map((arr) => {
 // arr[0] will have the key and arr[1] will have the value of a key-value 
 // pair of yourObject.
 console.log(arr) 
})

Answer 2

var result = {escalated_by: "Osten Diniz", ticket_Number: "SHA-194414", 
escalation_reason: "Closing sale", date: "2020-03-31T16:25:30.000Z"};

 // one
var keys= Object.keys(result);
keys.map(v => {
  console.log("KEY  ========>",v);
});

// two
var entries= Object.entries(result);
entries.map(v => {
   console.log("KEY  ========>",v[0],"VALUE  ========>",v[1]);
});
