javascript用空值创建json对象

Question

我有javascript日期数组

["2015-09-10", "2015-09-16"]

我希望json对象采用以下格式

{
"2015-09-10": {},
"2015-09-16": {}
}

我该怎么做？

var json = {};
var arr  = ["2015-09-10", "2015-09-16"] ;
$.each(arr,function(index,item)
{
     json[item] = {};
});

Answer 2

var result = JSON.stringify(["2015-09-10", "2015-09-16"].reduce(function(result, datum) {
    result[datum] = {};
    return result;
}, {}));
