我必須從陣列中創建一個物件，然后我才能使用它。我正在嘗試這段代碼它可以作業但輸出只有最后一個
let datas = "team1 1, team2 2, team3 3";
let teamdata = datas.split(" ");
var myObj = (function () {
var result = { Tname: null, count: null };
datas.split(/\s*\,\s*/).forEach(function (el) {
var parts = el.split(/\s* \s*/);
result.Tname = parts[0];
result.count = parseInt(parts[1]);
});
return result;
})();
console.log(myObj);
輸出獲取{ Tname: 'team3', count: 3 }
需要輸出
[{name: "team1", count: 1},
{name: "team2", count: 2},
{name: "team3", count: 3}]

簡單地說，你可以用
String.split()andArray.map()
let datas = "team1 1, team2 2, team3 3";
let teamdata = datas.split(", "); // ['team1 1', 'team2 2', 'team3 3']
let result = teamdata.map(team=>({team:team.split(/\s /)[0],count: team.split(/\s /)[1]}))
console.log(result);
預期輸出：
[{name: "team1", count: 1},
{name: "team2", count: 2},
{name: "team3", count: 3}]

我必須做一個物件
但是您隨后聲稱您的預期輸出是一個陣列，而不是一個物件：
[
{name: "team1", count: 1},
{name: "team2", count: 2},
{name: "team3", count: 3}
]
在這種情況下，創建一個陣列，然后.push()在回圈中創建該陣列：
var result = [];
datas.split(/\s*\,\s*/).forEach(function (el) {
var parts = el.split(/\s* \s*/);
result.push({
Tname: parts[0],
count: parseInt(parts[1])
});
});
return result;

這應該可以正常作業：
let datas = "team1 1, team2 2, team3 3";
var results = [];
var myObj = (function () {
var result = { Tname: null, count: null };
datas.split(/\s*\,\s*/).forEach(function (el) {
var parts = el.split(/\s* \s*/);
result.Tname = parts[0];
result.count = parseInt(parts[1]);
results.push(result);
});
return results;
})();
console.log(results)
您的代碼的問題是您成功拆分了字串并將其轉換為物件，但是由于您期望結果在陣列中，因此您沒有存盤物件，而是一次又一次地重寫同一個物件。
