javascript - 使用键 :value in one line 创建对象

Question

如果可能的话，我需要在一行中实现这一点:

我有一个对象

var object1 = {};

object1['key_1'] = "value_1";
object1['key_2'] = "value_2";
object1['key_3'] = "value_3";

我需要将对象中的一项(不仅是值)传递给函数，键 - 仅字符串值

for (var key in object1)
    FunctionTemp({key:object1[key]}); // - this don't work as I need, and eval() method I don't want

也许有这样的事情

FunctionTemp((new {})[key]=object1[key]) - its don't work!!! :)

由于您确实希望将其写在一行中，因此可以这样做:

var temp;
for (var key in object1)
    FunctionTemp(((temp = {}) && (temp[key] = object1[key]))? temp: null);

但我认为它不再可读，最理想的解决方案是将其分成几行。

var temp;
for (var key in object1) {
    temp = {};
    temp[key] = object1[key];
    FunctionTemp(temp);
}
