如何将多个对象放在JavaScript中的一个数组中？

我有这样的n 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个屈从于

这样的

'[{"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"}]'

结果，我尝试了以下内容，但是如果我推开它，它将进入数组本身。

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，然后将它们串成一个阵列。

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

Answer 2

您正在问如何将多个对象放在一个数组中，但是所需的输出是字符串对象。因此，我将所需的输出视为实际问题:)

您只需要通过Datalist迭代并将值合并到字符串对象中。

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

或只是

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