Javascript 对象映射(展平)

Question

您好，我有一个使用 JSON.Stringify 输出到此的对象

{"0":["test1","ttttt","","","","","","","",""],"1":["test2","ghjgjhgjh","","","","","","","",""]}

我想要这样的输出。

[["test1","ttttt","","","","","","","",""],["test2","ghjgjhgjh","","","","","","","",""]]

我尝试使用 .map 删除“0”和“1”

var itemjson = $.map(cleanedGridData, function (n) {
        return n;
    });

然而，这给出了(如下)的输出，该输出已经变平了。

["test1", "ttttt", "", "", "", "", "", "", "", "", "test2", "ghjgjhgjh", "", "", "", "", "", "", "", ""]

Answer 1

您可以使用它来提取值:

var res = {"0":["test1","ttttt","","","","","","","",""],"1":["test2","ghjgjhgjh","","","","","","","",""]}
Object.keys(res).map(function(key) {
    return res[key];
});

Object.keys 将列出初始对象中的所有键。然后，您可以使用 map 迭代这些键并在该函数中提取值。
