Example On Converting JSON Text To JavaScript Object

Json » on Feb 1, 2012 { 2 Comments } By Sivateja

Let us see this concept before we see an example

JSON arrays are written inside square brackets
Array can contain any number of objects

Syntax

{"names": ['+'{"name" : "java4s",  "address"  : "United States", "admin"  : "sivateja",  "age"  : 25},'+'{"name" : "php4s",  "address"  : "United States", "admin"  : "teja",  "age"  : 26}'+']}

Here names is an array containing 2 objects. By using JavaScript syntax we can access the values with the help of “.” operator, will show you this in the following example.

Example

<html>
<head>
<title>

</title>
<script language="javascript" >

var JsonObjecttext = '{"names": ['+'{"name" : "java4s",  "address"  : "United States", "admin"  : "sivateja",  "age"  : 25},'+'{"name" : "php4s",  "address"  : "United States", "admin"  : "teja",  "age"  : 26}'+']}';

var JsonObjectName = eval ("(" + JsonObjecttext + ")");

document.write("<font color='#148ee3' size='2' face='verdana'>Name - <font color='#000'>" +JsonObjectName.names[0].name+"</font></font> || ");
document.write("<font color='#148ee3' size='2' face='verdana'>Age. - <font color='#000'>" +JsonObjectName.names[0].age+"</font></font> || ");
document.write("<font color='#148ee3' size='2' face='verdana'>name - <font color='#000'>" +JsonObjectName.names[1].name+"</font></font> || ");
document.write("<font color='#148ee3' size='2' face='verdana'>name - <font color='#000'>" +JsonObjectName.names[1].age+"</font></font>");

</script>
</head>
<body>
<br>
<font face="verdana" size="4">Example On Createing JSON Object Array</font><br><br>

<font face="verdana" color="#ff0024" size="2">
Note:<br>
<font color="#000">
var JsonObjectName - Here JsonObjectName is the object name, <br>can give your own name.</font></font>
</body>
</html>
