Parse JSON string to javascript object with exact values

Question

I want to parse a JSON string to a javascript object with the exact values of the JSON string.

When I call JSON.parse on a JSON string like eg { "someArray": [1.0, 2, 3.7] } I want exactly the numbers 1.0 , 2 and 3.7 in my object. Unfortunately I get 1 , 2 and 3.7 .

How do I parse a JSON string like the one above in an object with the exact values of the string?

Answer 1

In javascript there is no difference between 1.0 and 1 as all numbers are doubles. As far as your parsed data is concerned there is no difference. Try evaluating [1.0, 2.0, 3.0] in your browser console.

 console.log([1.0, 2.0, 3.0]) 

If you really need the string representation of nodes in your JSON, you'd have to use a parser, and walk the parse tree. Something like the acorn parser, for example.

Answer 2

Here you are doing a mistake

{ "someArray": [1.0, 2, 3.7] }

Data in your array [1.0,2,3.7] are integer now and in any programming there are no difference between 1 or 1.0 as integer so change them into string by applying this

{ "someArray": ["1.0", "2", "3.7"] }

Stay trying new 😛

Answer 3

将someArray的值转换为字符串
