我怎样才能使这个 JSON.stringify 正常工作

Question

I have a small issue to make my arrays into the json I want to. I have made this code:

 var arrData = [{label:Test,value:199.12}, {label:Test2,value:1024}] var data = []; for (var i = 0; i < arrData.length; i++) { data.push(JSON.stringify({ label: arrData[i][2], value: arrData[i][3] }).replace(/\"/g, "").replace("\\r", "")) }

It also does the job properly. But I do want it to be in this format:

{ label: 'Food', value: 90 },

I want to have the ' ' on the label data and I want to remove the double "" punctuation mark outside the json. Since my current json looks like this:

"{label:Test,value:199.12}", "{label:Test2,value:1024}",

{ label: 'Food', value: 90 } isn't valid JSON so you cannot create it using JSON.stringify .

It isn't any standard serialisation format (although it is a valid JavaScript literal) so if you want to serialise data to it, you'll need to write a custom serialiser.

You could loop over the properties of the object and append them, the associated values, and whatever quotes and commas your format demands, to a string.
