如何在javascript中将多个对象放在一个数组中？

我有n个这样的json字符串：

first object
'[{"name":"1","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"Platform", "name":"1"}]'

second object
'[{"name":"2","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"Platform", "name":"2"}]'

third object
'[{"name":"3","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"Platform", "name":"3"}]'
...
nth object

在这里，我想将 n 个对象放入一个结果中

像这样

'[{"name":"1","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"승강장","name":"1"},
[{"name":"2","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"승강장","name":"2"}],
[{"name":"3","position":{"x":-28.890169060450745,"y":-89.45,"z":103.39384013230637},"property":{"floor":"승강장","name":"3"}]'

为此，我尝试了以下操作，但如果我推动它，它会进入数组本身。

for (let i = 0; i < DataList.length; i++) {
    if (i == 0) {
        mergetData = JSON.parse(DataList[0]);
        continue;
    } else {
        mergetData.push(JSON.parse(DataList[i]));
    }
}

我想知道如何解决这个问题。

此致！

Answer 1

解析所有 JSON 数组，然后将它们连接成一个数组。

let parsedData = Datalist.map(s => JSON.parse(s));
let mergeData = [].concat(...parsedData);

您在问如何将多个对象放在一个数组中，但您想要的输出是字符串对象。 所以我正在考虑您想要的输出作为实际问题:)

为此，您只需遍历您的DataList并将值合并到一个字符串对象中。

StringObject = ''
for(let i=0; i < DataList.length; i++){
    if(i===0)
        StringObject += DataList[i]
    else
        StringObject += ',' + DataList[i]
}
console.log(StringObject)

要不就

StringObject = String(DataList)
console.log(StringObject)
