Answer 1

这是JSON个对象。要从中获取任何价值，您需要知道key name，例如： - jsonObj["x"]和jsonObj["y"]。

但是，如果您不知道密钥名称，则将其迭代为： -

$.each(jsonObj,function(k,v){

//get value by using v or jsonObj[k];

});

var data={};
data["0"]=["The VehicleNumber field is required."];
data["1"]=["The NumberSeats field is required."];
data["2"]=["The VehicleCode field is required."];
data["3"]=["The MaximumAllowed field is required."];
data["4"]=["The City field is required."];
data["5"]=["The State field is required."];
data["6"]=["The Phone field is required."];
data["7"]=["The Insurance field is required."];

Answer 2

我不确定我的问题是否正确，但不应该做以下工作？

console.log(myObj["y"][0] + " " + myObj["x"][0])

Answer 3

    var data = '{
    "0": [
        "The VehicleNumber field is required."
    ],
    "1": [
        "The NumberSeats field is required."
    ],
    "2": [
        "The VehicleCode field is required."
    ],
    "3": [
        "The MaximumAllowed field is required."
    ],
    "4": [
        "The City field is required."
    ],
    "5": [
        "The State field is required."
    ],
    "6": [
        "The Phone field is required."
    ],
    "7": [
        "The Insurance field is required."
    ],
    "9": [
        "The Address field is required."
    ]
}';
    data = JSON.parse(data);
    alert (data[0]);
    alert (data[1]);

Answer 4

您在问题中提到的构造不是数组，而是对象。

要打印对象内的所有数组值，可以使用 -

var data = {
    "x": [ "The 0 has already been taken." ],
    "y": [ "The 2 has already been taken." ]
}
for (var key in data) {
  if (data.hasOwnProperty(key)) {
     console.log("First=",data[key][0]);
    }
}

如何从数组中获取第一个元素和第二个元素内的值
