JSON : JavaScript Ojbect Notation.
It contains name/value pairs, array and other object for passing aroung ojbect in java script. It is subset of JavaScript and can be used as object in javascript.
You can use JSON to store name/value pair and array of ojbect.
It has eval() method to assign value to variable.
In below example, I have put all things together.
Just make one html file and you can start your practice on it.
How to use this tutorial:
1. Make one file JSONDemo.html
2. And paste below code
<html>
<head>
<body>
<script language="javascript">
eval("var amount =10;");
alert("Value of amount :: "+amount);
var student = {
name : "Binod",
roll : 110,
subject : ["Java","Database","Networking"]
}
alert("Student Name :: "+student.name);
alert("Student All Subject :: "+student.subject);
alert("Student First Subject :: "+student.subject[0]);
alert("Student No. of Subject :: "+student.subject.length);
for(var i=0;i<student.subject.length;i++){
var value = student.subject[i];
alert(value);
}
var person = {
name : "Ambani",
books : [
{
title : "Java Programming",
author : "Binod Suman"
},
{
title : "XML",
author : "Don Box"
}
]
}
alert("Book Title :: "+person.books[0].title);
alert("Book Author :: "+person.books[0].author);
