You can use:

var myarray = [];
var myJSON = "";

var item = {
    "rollno": "10",
    "typeofattendence": 1
  };

myarray.push(item);

item = {
    "rollno": "10021",
    "typeofattendence": 0
  }
myarray.push(item);

myJSON = JSON.stringify({myarray: myarray});

As this http://jsfiddle.net/jensbits/MWSeg/ toturial says.

You should store your object in an array first. For example.

let data = [];
data.push({
 rollno: this.state.data,
 typeofattendence: this.state.value
});

and when you want to send it to the server

body: JSON.stringify(data);
