用JSON编码元组的最佳方法 [英] Best way to encode tuples with json

问题描述

在python中，我有一个将元组映射到元组列表的字典.例如

In python I have a dictionary that maps tuples to a list of tuples. e.g.

{(1,2): [(2,3),(1,7)]}

我希望能够使用javascript对这些数据进行编码，因此我调查了json，但发现键必须是字符串，因此我的元组不能用作键.

I want to be able to encode this data use it with javascript, so I looked into json but it appears keys must be strings so my tuple does not work as a key.

处理此问题的最佳方法是将其编码为"1,2"，然后将其解析为我想在javascript上找到的内容?还是有更聪明的方法来处理这个问题.

Is the best way to handle this is encode it as "1,2" and then parse it into something I want on the javascript? Or is there a more clever way to handle this.

推荐答案

您可能会考虑说

{"[1,2]": [(2,3),(1,7)]}

，然后当您需要获取值时，您可以将键本身解析为JSON对象，所有现代浏览器都可以使用内置的JSON.parse方法来实现(我正在使用jQuery.each进行迭代在这里，但您可以使用任何东西):

and then when you need to get the value out, you can just parse the keys themselves as JSON objects, which all modern browsers can do with the built-in JSON.parse method (I'm using jQuery.each to iterate here but you could use anything):

var myjson = JSON.parse('{"[1,2]": [[2,3],[1,7]]}');
$.each(myjson, function(keystr,val){
    var key = JSON.parse(keystr);
    // do something with key and val
});

另一方面，您可能希望仅以不同的方式构造对象，例如

On the other hand, you might want to just structure your object differently, e.g.

{1: {2: [(2,3),(1,7)]}}

所以不用说

myjson[1,2] // doesn't work

您可能会说这是无效的Javascript语法

which is invalid Javascript syntax, you could say

myjson[1][2] // returns [[2,3],[1,7]]
