在javascript中将JSON对象转换为逗号分隔的值

Question

I have a JSON OBJECT

{"data":{"source1":"source1val","source2":"source2val"}}

which i want to convert into

data : source1val, source2val.

Answer 1

Use Object.keys with Array#map

The Object.keys() method returns an array of a given object's own enumerable properties.

---

The map() method creates a new array with the results of calling a provided function on every element in this array.

 var input = { "data": { "source1": "source1val", "source2": "source2val" } }; var output = Object.keys(input.data).map(function(k) { return input.data[k]; }).join(','); console.log(output); //manipulated object console.log(input); //Original object

Answer 2

var input = {
  "data": {
    "source1": "source1val",
    "source2": "source2val"
  }
};
var output = [];
var i;
for (i = 0; i < input.data.length; i++) { 
    output.push(input.data[i]);
}
