将javascript数组转换为相同键/值的对象

Question

我有一个返回数组的函数,如下所示:

但我正在尝试填充SweetAlert2对话框.

正如文档所示,所需的输入将如下所示

inputOptions: {
    'SRB': 'Serbia',
    'UKR': 'Ukraine',
    'HRV': 'Croatia'
  },

考虑到密钥与值相同,我怎样才能将我的数组转换为所需的格式？

所以,这样的结果将是结果:

{
    'aaa123': 'aaa123',
    'Açucena': 'Açucena',
    'Braúnas': 'Braúnas',
    [...]
}

我试过了JSON.stringify,但输出不是我需要的:

"[[" AAA123" , "Açucena", "布劳纳斯","C.Fabriciano " "格格", "gegeq2", "伊帕廷加", "若阿内夏", "梅斯基塔", "Rodoviário", "睾丸中", "teste2", "TIMOTEO", "Tomatoentro", "TS"]]"

Answer 1

这可以通过简单的reduce调用完成:

// Demo data
var source = ['someValue1', 'someValue2', 'someValue3', 'other4', 'other5'];


// This is the "conversion" part
var obj = source.reduce(function(o, val) { o[val] = val; return o; }, {});


// Demo output
document.write(JSON.stringify(obj));
