Question

我有一组结果，我已经使用php json_encode函数转换为Json，现在我希望这个结果作为js中的数组，但我不知道这样做。

我的PHP数组是这样的：

Array
(
    [latestRating] => Array
        (
            [456] => Anonymous has rated xxx9
            [457] => Anonymous has rated xxxx8
            [458] => Anonymous has rated xxxx3.5
        )

    [latestUser] => Array
        (
            [242] => xxxxhas just signed up
            [243] => xxxxxhas just signed up
            [244] => xxxxxxhas just signed up
        )

)

当我在这上面执行php json_encode函数时，我得到以下字符串

{"latestRating":{"456":"Anonymous has rated mermaidbl00d 9","457":"Anonymous has rated GeorgiaHallx 8","458":"Anonymous has rated smithjhon 3.5","459":"Anonymous has rated Emilyxo 8.5","460":"Anonymous has rated leona 10","461":"Anonymous has rated leona 10","462":"Anonymous has rated W0rthlessliar 8","463":"Anonymous has rated Yousamsuck 9","464":"Anonymous has rated Aimeeerobbb 9","465":"Anonymous has rated lauramillerx 10","466":"Anonymous has rated tomwaz 1","467":"Anonymous has rated W0rthlessliar 1","468":"Anonymous has rated W0rthlessliar 1","469":"Anonymous has rated W0rthlessliar 1","470":"Anonymous has rated W0rthlessliar 1"},"latestUser":{"242":"rhiwilliamsx has just signed up","243":"W0rthlessliar has just signed up","244":"rebeccaronan has just signed up"}}

我尝试使用JSON.stringify，然后使用jQuery.makeArray创建一个数组。然后我尝试了eval（'['+ string +']'），但没有一个帮助过。

我是Json的新手也无法找到合适的支持。

Answer 1

使用JSON.parse()代替JSON.stringify 第一个是JavaScript相当于PHP的json_decode，后者相当于json_encode。

注意：如果您将jQuery.ajax与dataType: 'json'一起使用，则回调中的参数已经是解码对象。

在您的代码中，PHP“数组”不是JavaScript数组，而是对象。

Answer 2

如果您使用json_encode()，它应该已经准备好了，如果没有，请使用JSON.parse()。您还可以在回显要包含的数据时检查PHP标头：

header('Content-type: application/json');

如果它从ajax响应中返回，只需像这样引用对象：

success : function(data) {
    console.log(data.latestRating);
}

Json字符串到js数组
