var abc = '{ "age":26, "city :PUNE",''name:siddhanam" }';
var anobj = JSON.parse(myJSON);
document.getElementById("abc").innerHTML = myObj.name;
<h2>Convert a string written in JSON format, into a JavaScript object.</h2>
<p id="abc"></p>
var anobj = JSON.parse(myJSON);
document.getElementById("abc").innerHTML = myObj.name;

common use of JSON is to exchange data to/from a web server. When receiving data from a web server, the data is always a string. Parse the data with JSON.parse(), and the data becomes a JavaScript object.
now let us see JSON with php
<!DOCTYPE html>
<html>
<body>
<h2>Example of JSON.</h2>
<p id="abc"></p>
<script>
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var myObj = JSON.parse(this.responseText);
document.getElementById("demo").innerHTML = myObj[2];
}
};
xmlhttp.open("GET", "trial.php", true);
xmlhttp.send();
</script>
</body>
</html>

in above code there is getting result of trial.php file and assign value to demo div.
suppose you type an address in trial.php or anything data by using this xmlhttp request & get method browser will show result.
json is not need any external installation .
our aim is to gain & share more & more knowledge.suppose you type an address in trial.php or anything data by using this xmlhttp request & get method browser will show result.
