Using JavaScript to transform a string into a multidimensional array

Question

Using JavaScript to transform a string into a multidimensional array

I am currently working with sockets (server and client) and I have been attempting to send a matrix. My goal is to send a string array and then convert it into a variable called "ARRAY". For instance, if I want to send an array structured like this:

edit `

var myString = "[\"Item\", \"Count\"],[\"iPad\",2],[\"Android\",1]";

var arr = JSON.parse("[" + myString + "]");
alert(arr[0][0]);

`

I came across this example, but it is not a multidimensional array. What I am looking for is to be able to access elements like School.Section(1).User(1).Name

Answer №1

Construct your structure using JavaScript and experiment with the functions JSON.stringify and JSON.parse.

For instance:

var Classroom = {
  Grade: [
    {
      Students: [
        {
          Name: "Tom Smith"
        },
        {
          Name: "Emily Brown"
        }
      ]
    }
  ]
};

var dataString = JSON.stringify(Classroom);
// Result will be `{"Grade":[{"Students":[{"Name":"Tom Smith"},{"Name":"Emily Brown"}]}]}`

var parsedClassroom = JSON.parse(dataString);
// Works like a charm!

var studentName = parsedClassroom.Grade[0].Students[1].Name;
// Will output `Emily Brown`.
