我有一个大数组（下面提供了简短示例），并且想要格式化 REPORT_DATE 值，以便我得到 2015 年 5 月 31 日而不是“31/05/2015 00:00:00”。有谁知道一个简单的方法来做到这一点？

{["data":[{"DOC1":"1234","FILE_NAME":"4321.PDF","TITLE":"gwewrgw","REPORT_DATE":"31/05/2015 00:00:00","CLIENT_ID":"1234512","CLIENT_NAME":"Zuba"}
     ,{"DOC1":"4737","FILE_NAME":"52345.PDF","TITLE":"erywery","REPORT_DATE":"30/09/2015 00:00:00","CLIENT_ID":"5234523","CLIENT_NAME":"Ziba"}

让我向您介绍for loop...
你想把值"31/05/2015 00:00:00" 改成"31/05/2015"
["data": 在 javascript 中无效，它会抛出 Uncaught SyntaxError: Unexpected token :
我正在尝试学习一种比常规 for 循环更好的方法，因为我确信这是一个 1-2 行的东西，带有 lodash 和下划线，但我似乎做不到。 @Pranav 尝试格式化“REPORT_DATE”值，以便“00:00:00”不出现
迭代内部数组并更新对象属性....用于使用空格更新拆分字符串并在索引0处获取字符串

【解决方案1】：

您粘贴了格式错误的 sn-p，顺便说一下，如果您不需要内存引用，可以使用 `Array.prototype.map' 修改数组

"use strict";

var data = [{"DOC1":"1234","FILE_NAME":"4321.PDF","TITLE":"gwewrgw","REPORT_DATE":"31/05/2015 00:00:00","CLIENT_ID":"1234512","CLIENT_NAME":"Zuba"}];

var result = data.map(i => {
  i.REPORT_DATE = Date.apply(null, i.REPORT_DATE.split(' ').reverse());
  
  return i;
});

console.log(result)
