如何在javascript中使用PHP数组或json响应？

让我简要介绍一下我的流程

当我从index.phtml文件调用Ajax时，Ajax会返回此响应

Array
(
    [Data] => Array
        (
            [0] => Array
                (
                    [PlayerId] => 201503261611120312176355026
                    [PlayerName] => Leonel Messi
                    [PlayerPossition] => Striker
                    [PlayerPrice] => 15
                    [PlayerNationality] => Argentina
                    [ImageUrl] => messi.jpg
                )

            [1] => Array
                (
                    [PlayerId] => 2015040711252904291525683176
                    [PlayerName] => Simon Mignolet
                    [PlayerPossition] => Goalkeeper
                    [PlayerPrice] => 12
                    [PlayerNationality] => Belgium
                    [ImageUrl] => Mignolet.jpg
                )

            [2] => Array
                (
                    [PlayerId] => 201503301517200320707502096
                    [PlayerName] => Petr Cech
                    [PlayerPossition] => Goalkeeper
                    [PlayerPrice] => 10
                    [PlayerNationality] => czech Republic
                    [ImageUrl] => Petr.jpg
                )
)

这是因为当我调用一个API时，它会给我这样的json字符串，我会对它进行解码，这样我们就可以得到上面的结果

{"Data":[{"PlayerId":"201503261611120312176355026","PlayerName":"Leonel Messi","PlayerPossition":"Striker","PlayerPrice":"15","PlayerNationality":"Argentina","ImageUrl":"messi.jpg"},
         {"PlayerId":"2015040711252904291525683176","PlayerName":"Simon Mignolet","PlayerPossition":"Goalkeeper","PlayerPrice":"12","PlayerNationality":"Belgium","ImageUrl":"Mignolet.jpg"},
         {"PlayerId":"201503301517200320707502096","PlayerName":"Petr Cech","PlayerPossition":"Goalkeeper","PlayerPrice":"10","PlayerNationality":"czech Republic","ImageUrl":"Petr.jpg"}]
}

最后，我的问题是什么

我想在javascript中使用API的响应作为数组，因此，我正在对来自API的字符串进行json_解码，我应该将字符串或ket解码为json字符串，以便在javascript中进一步使用？如果是，那么如何在javascript中使用json字符串作为数组

如果否，那么如何使用上面在javascript中显示的PHP数组作为数组

需要帮助！ 它只是需要如何使用它的指导，我已经看到曼尼在这个话题上的问题，但没有得到正确的答案

这是完整的回答

您可以使用

JSON.parse（JSON）要将其转换为对象，请使用该对象！：）

下面是一个演示，向您展示它返回的内容：

使用

var obj = {"Data":[{"PlayerId":"201503261611120312176355026","PlayerName":"Leonel Messi","PlayerPossition":"Striker","PlayerPrice":"15","PlayerNationality":"Argentina","ImageUrl":"messi.jpg"},{"PlayerId":"2015040711252904291525683176","PlayerName":"Simon Mignolet","PlayerPossition":"Goalkeeper","PlayerPrice":"12","PlayerNationality":"Belgium","ImageUrl":"Mignolet.jpg"},{"PlayerId":"201503301517200320707502096","PlayerName":"Petr Cech","PlayerPossition":"Goalkeeper","PlayerPrice":"10","PlayerNationality":"czech Republic","ImageUrl":"Petr.jpg"}]}

现在您可以访问如下元素，例如：

obj.Data[0].PlayerId

要解析或创建JSON字符串，有以下两个函数：

JSON.parse()
JSON.strigify()

使用

var obj = {"Data":[{"PlayerId":"201503261611120312176355026","PlayerName":"Leonel Messi","PlayerPossition":"Striker","PlayerPrice":"15","PlayerNationality":"Argentina","ImageUrl":"messi.jpg"},{"PlayerId":"2015040711252904291525683176","PlayerName":"Simon Mignolet","PlayerPossition":"Goalkeeper","PlayerPrice":"12","PlayerNationality":"Belgium","ImageUrl":"Mignolet.jpg"},{"PlayerId":"201503301517200320707502096","PlayerName":"Petr Cech","PlayerPossition":"Goalkeeper","PlayerPrice":"10","PlayerNationality":"czech Republic","ImageUrl":"Petr.jpg"}]}

现在您可以访问如下元素，例如：

obj.Data[0].PlayerId

如果您希望javascript使用JSON字符串，那么您根本不需要对其进行解码，那么我如何将该JSON字符串用作我尝试过的数组data.data，data['data']其中datais var和“Data是第一个键”。但它不起作用。请看一看文章：它使用json字符串并将其解析到数组中，然后您就可以对该数组值运行一个查找。@Daedalus表示数据是一个键，在执行
json.parse（json）之后，它具有数组
我正在做
data.data[0]
它给了我对象，但问题是一个错误
Uncaught SyntaxError:Unexpected token u

我做了一个测试，你可以看看上面的这个给定链接！（在您的开发工具中）没有正确输出json没有错误是的，您的输出json中有错误。我只是将

添加到最后一个右括号

之前，因此您应该检查生成json文件的代码！我已经这样做了，但是我面临这个错误
