Question

你能告诉我怎么用手印读杰森吗?

我有一个json 弦如铃声

 {"person":{"First name":"Dharmalingm","Last name":"Arumugam","Address":{"door number":"123","street":"sample street","city":"sample_city"},"phone number":{"mobile":"0123","landline":"01234","skype":"01235"}}}

我想读读 < enger> skype 的电话号码

Answer 1

这应该能让你上路

var o = {"person":{"First name":"Dharmalingm","Last name":"Arumugam","Address":{"door number":"123","street":"sample street","city":"sample_city"},"phone number":{"mobile":"0123","landline":"01234","skype":"01235"}}}

o["person"]["phone number"]["skype"];

/* or */

o.person["phone number"]["skype"];

Answer 2

如果您是以 JSON 字符串开头, 请以 < code> 1 开头。如果您已经有 JS 对象, 请跳转到 < code> 2 。

使用“https:// developmenter.mozilla.org/en/javaScript/Reference/Global_Objects/Json/parse” rel=“nofollow”\\code>Json.parse () 将JSon字符串转换为 JSON 的 JSON 对象。支持的浏览器, 一个没有本地 JSON < /a> 的浏览器, 您可以使用 < a href= 来实施它。
```
var jsondata = JSON.parse( {"person":{"First name":"Dharmalingm","Last name":"Arumugam","Address":{"door number":"123","street":"sample street","city":"sample_city"},"phone number":{"mobile":"0123","landline":"01234","skype":"01235"}}} );
```

从 JUS 对象中获取您通常一样的数值

var skype = jsondata.person[ phone number ].skype;

此处的代码完整, 样本 :

var jsondata = JSON.parse( {"person":{"First name":"Dharmalingm","Last name":"Arumugam","Address":{"door number":"123","street":"sample street","city":"sample_city"},"phone number":{"mobile":"0123","landline":"01234","skype":"01235"}}} );

//normally, the dot-notation is used
//but since "phone number" is not a valid key when using dot-notation
//the bracket notation is used
var skype = jsondata.person[ phone number ].skype;

Answer 3

首先,它需要解析到本地的 javascript 对象, 在现代浏览器中, 可以通过 < code> Jsson.parse( json string here) 进行 ; 。现在, 要具体获取您刚刚解析的天平号, 您需要将天花板切开。让我们假装您通过 < code> var skypeData = Jsson.parse( json string here); , 个人天花板号码可以通过 < code> skypeData. person [phone].skype < /code > 进入。我们必须使用 < code> [ phone number] 而不是 person. phonenumber.skype , 因为空间的原因, 。
