Question

I have the following string coming in from users and need to turn it into JSON.

2r,5g|3b,2r,4y|3g

I would like to convert it to JSON with JavaScript. Here is what I would like the JSON to look like:

rounds = { 
    "round" : {
        "interval" : {
            "time" : "2",
            "color" : "r"
        },
        "interval" : {
            "time" : "5",
            "color" : "g"
        }
    },
    "round" : {
        "interval" : {
            "time" : "3",
            "color" : "b"
        },
        "interval" : {
            "time" : "2",
            "color" : "r"
        },
        "interval" : {
            "time" : "4",
            "color" : "y"
        }
    },
    "round" : {
        "interval" : {
            "time" : "3",
            "color" : "g"
        }
    }
}

I’m not really sure where to start here so any help is appreciated!

You can use this code:

var strRounds = "2r,5g|3b,2r,4y|3g";
var roundsSplit = strRounds.split("|");

var rounds = {};

for (var i = 0; i < roundsSplit.length; i++){
    var intervalsSplit = roundsSplit[i].split(",");

    if (intervalsSplit.length > 0){
        rounds["round" + i] = {};
    }

    for (var j = 0; j < intervalsSplit.length; j++){
        rounds["round" + i]["interval" + j] = {
            "time": intervalsSplit[j][0],
            "color": intervalsSplit[j][1]
        };
    }
}

But I have to say, that JSON written by you is not valid because its’ fields must have unique names. I’ve used names like round0, round1… and interval0 and so on.
