javascript - 将javascript数组转换为具有相同键/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。

As the documentation exemplifies ，所需的输入看起来像这样

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

考虑到键与值相同，我如何将我的数组转换为所需的格式？

所以，结果会是这样的:

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

我试过 JSON.stringify，但输出不是我需要的:

"[["aaa123","Açucena","Braúnas","C. Fabriciano","gege","gegeq2","Ipatinga","Joanésia","Mesquita","Rodoviário","teste","teste2","Timóteo","Tomatoentro","ts"]]"

Answer 1

这可以通过简单的 reduce 调用来完成:

// 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));
