Answer 1

您可以使用arr [0] .pathmp3

访问此值

var arr= [
    {
    "id":2578774,
    "word":"apple",
    "addtime":"2013-11-04 21:40:05",
    "hits":6796,
    "username":"JerrySun",
    "sex":"m",
    "country":"United States",
    "code":"en",
    "langname":"English",
    "pathmp3":"http:\/\/apifree.forvo.com\/audio\/3l2h333f1p3d1h2a363f2j3b2h2j282e3f373m2b3f2k1g31231n3m3i3l331n2637361i3g393c293j243i3l2c3o341b2p291j2k1n1l1o3m233p2e1g1h2i343m25_2925241j3a1j3f342e232c3k2k212n2i29263p352i3n1t1t",

    "rate":5,
    "num_votes":5,
    "num_positive_votes":5
    }
];

alert(arr[0].pathmp3);

Answer 2

您的Object似乎有一个String实际上是Array。

只需alert(myString[0].pathmp3);

myString[0]将访问第一个（也是唯一的）对象，并且附加到其中的.pathmp3将访问该对象的pathmp3属性。

工作代码段：

var myString= [
    {
    "id":2578774,
    "word":"apple",
    "addtime":"2013-11-04 21:40:05",
    "hits":6796,
    "username":"JerrySun",
    "sex":"m",
    "country":"United States",
    "code":"en",
    "langname":"English",
    "pathmp3":"http:\/\/apifree.forvo.com\/audio\/3l2h333f1p3d1h2a363f2j3b2h2j282e3f373m2b3f2k1g31231n3m3i3l331n2637361i3g393c293j243i3l2c3o341b2p291j2k1n1l1o3m233p2e1g1h2i343m25_2925241j3a1j3f342e232c3k2k212n2i29263p352i3n1t1t",
