我正在尝试将其插入嵌套,如下所示:
[{
"chatid": 10000414,
"connected": true,
"index": 0,
"jsonedUser": {},
"membership": "",
"messages": [{
"chatid": 10000414,
"createdOn": "2018-10-29T16:50:44.4900000",
"isArchive": false,
"isNew": false,
"message": "great",
"messageid": 3,
"sentby": {
"id": 59,
"name": "Ana"
}
}, {
"chatid": 10000414,
"createdOn": "2018-10-25T13:49:50.9900000",
"isArchive": false,
"isNew": false,
"message": "hi",
"messageid": 2,
"sentby": {
"id": 59,
"name": "Ana"
}
}, {
"chatid": 10000414,
"createdOn": "2018-10-31T10:20:59.5000000",
"isArchive": false,
"isNew": false,
"message": "hello there",
"messageid": 1,
"sentby": {
"id": 91,
"name": "Miliam"
}
}],
"opened": true,
"port": 10842,
}]
我尝试将类似的对象推入消息内[]我不知道该怎么办,因为有人可以帮助我
我尝试像这样
var chat = { chatid: 10000414, createdOn: "2018-10-29T16:50:44.4900000", isArchive: false, isNew: false, message: val, messageid: 3, sentby: {id:59, name:"betsynray"} }
var newSingleChat = singleChat[0].messages.push(val);
但是当我使用newSingleChat时,您会显示“ 4”
答案 0 :(得分:0)
您似乎对Array#push和Array#concat感到困惑。
.push()
将修改原始数组并返回新长度。
var array = [1, 2, 3];
var result = array.push("a");
// array: [1, 2, 3, "a"]
// result: 4
.concat()
将基于旧数组和新值返回一个新数组。
var array = [1, 2, 3];
var result = array.concat("a");
// array: [1, 2, 3]
// result: [1, 2, 3, "a"]

谢谢,我使用
解决了这个问题var newSingleChat = singleChat[0].messages.concat(chat);
现在一切正常,这要感谢@James Long的所有帮助
