Json extract and use data (node.js)

Question

How can I access this data?

Here is my Json:

 {
  \"6a768d67-82fb-4dd9-9433-d83dbd2f1b78\": {
    \"name\": \"Bahut\",
    \"11\": {
      \"timestam         


        

Answer 1

You could use Object.keys to get an array of properties.

var js = JSON.parse(json);
var props = Object.keys(js);

var result = props.map(function(prop) {
  return {
    id: prop,
    name: js[prop].name;
  };
});

The final result is an array of objects with 2 properties: id, name

Answer 2

If you want to loop through the data, use a for in loop:

for (var key in obj) { //obj is your data variable
    console.log(key); //xxxx-x-xx-x-x-xxxx
    console.log(obj[key].name); //the name for each
}

Answer 3

You need to use array-style access to get the subobject associated with the id key:

var nameid = json["a12d22cc-240e-44d6-bc58-fe17dbb2711c"].name; // or ["name"]
// nameid => "Cuis"

This is because hyphens are not a valid character for dot-style access (can't use them in variable names in JavaScript).

In order to extract all of the you will need to loop through the object, and add them to an array, like so:

var arr = [];
for (var id in json) {
    arr.push(json[id]["name"]);
}

Which will give you an array of all the names in that JSON object.

Answer 4

not a common way of looping, but in this case you could loop over the json object

for (var prop in json){
     print("prop",json[prop].name);
}

Answer 5

Access the JSON like you would an array, eg:

data["a12d22cc-240e-44d6-bc58-fe17dbb2711c"].name
