嵌入在json字符串中的日期 [英] Date embedded in json string

问题描述

我有一个函数，该函数接收一个String并将其转换为json对象.

I've a function, that receives a String and convert It to a json Object.

问题是，有时te函数可以获取一个Date，而我需要将它作为一个date！ (不是字符串).

The problem is, that sometimes, te function could recibe a Date, and I need it to be a date! (Not a string).

例如，我发送给函数的字符串是这样的:

For example, the string that I send to the function is like this:

[{
        "date" : new Date(2013 - 01 - 01),
        "Weigth" : "120.00"
    }, {
        "date" : new Date(2013 - 01 - 01),
        "Weigth" : "110.00"
    }
]

在其他情况下，字符串将如下所示:

In other cases, the string will look like this:

[{
        "age" : 12,
        "Weigth" : "120.00"
    }, {
        "age" : 15,
        "Weigth" : "110.00"
    }
]

但是，在第一个示例中，解析器将引发错误. 如何检测到这种情况，并强制解析器生成带有此属性的javascript对象?

But, in the first example, the parser throws an error. How can I detect this case, and force the parcer to generate an javascript object with this atributes?

谢谢！

推荐答案

最简单的方法是eval()您的字符串，但是我建议您生成一个正确的JSON，因为eval()可能会导致以下问题:不值得通过这种简单的转换来获取利润:

The easiest way is to eval() your string but I would suggest you to generate a correct JSON instead because eval() may lead to the problems that doesn't worth the profit of this easy conversion:

var invJSIN = '[{"date":new Date(2013-01-01),"Weigth":"120.00"},{"date":new Date(2013-01-01),"Weigth":"110.00"}]'
var something = eval(invJSON)
