Answer 1

Using the function forEach would be the cleanest way.

var data = [{    "Id": 4,    "Created_at": "2017-11-04T15:47:17Z"},{    "Id": 5,    "Created_at": "2017-11-05T15:53:24Z"},{    "Id": 6,    "Created_at": "2017-11-05T18:59:32Z"},{    "Id": 7,    "Created_at": "2017-11-05T20:05:39Z"}];

data.forEach(d => d.Created_at = d.Created_at.replace('T', " ").replace("Z", ""));
console.log(data)

.as-console-wrapper { max-height: 100% !important; top: 0; }

I'm sure there is a better date related solution, but you could easily use map() to loop through and remove the letters

data.map(item => ({ Id: item.Id, Created_at: item.Created_at.replace(/T/g,' ').replace(/Z/g, '')}))

var data = [
{
    "Id": 4,
    "Created_at": "2017-11-04T15:47:17Z"
},
{
    "Id": 5,
    "Created_at": "2017-11-05T15:53:24Z"
},
{
    "Id": 6,
    "Created_at": "2017-11-05T18:59:32Z"
},
{
    "Id": 7,
    "Created_at": "2017-11-05T20:05:39Z"
}
]

console.log(data.map(item => ({ Id: item.Id, Created_at: item.Created_at.replace(/T/g,' ').replace(/Z/g, '')})))

这将是最干净的方式：

data.map(obj => {
  return { Id: obj.Id, Created_at: obj.Created_at.slice(0, -1) }
})

How can i remove T and Z from this Jsonarray
