If this is your real server side code then...its completely insecure. You should never pass variables posted by users directly into your queries.

$query2 = "insert into booking(cust_email, cust_mobile, cust_name) values('$mail','$mobile','$name')";

At least escape the values using "mysql_real_escape_string", or use prepared statements. And...dont use mysql anymore, use mysqli, which is almost identical to what you are using, but not deprecated soon.

Also, you are json encoding a string that doesnt need to be json encoded, its just a piece of text and not valid json code. This may be why @SimarjeetSingh Panghlia answer doesnt work for you.

instead of json_encoding that value, encode a structured array.

$response = array( "status" => true );

if(isset($_POST['type']))
    {
        if($_POST['type']=="booking"){
            $name = mysql_real_escape_string( $_POST ['Name'] ));    
            $mobile = mysql_real_escape_string($_POST ['Mob_Num']);
            $mail = mysql_real_escape_string($_POST ['Email']);               
            $query1 = "insert into customer(userName, userContactNumber, email) values('$name','$mobile','$mail')";
            $query2 = "insert into booking(cust_email, cust_mobile, cust_name) values('$mail','$mobile','$name')";          

            $result1 = mysql_query($query1);          
            $result2 = mysql_query($query2);
            $id = mysql_insert_id();

            $response["message"] = "Welcome Mr/Mrs ".$name."  Thanks for booking home services your booking id is =  ".$id;/* make sure you strip tags etc to prevent xss attack */

        }
    }
    else{
        $response["status"] = false;
        $response["message"] = "Invalid format";
    }

    echo json_encode($response);

    /* Note that you are making the query using ContentType:"application/json", */

which means you should respond using json regardless if query is successful or not. I would also recommend using a simple jQuery plugin called jStorage, that allows easy get/set of objects without having to serialize them.

You can use sessionStorage to store and retrieve JSON Data.

var complexdata = [1, 2, 3, 4, 5, 6];

// store array data to the session storage
sessionStorage.setItem("list_data_key",  JSON.stringify(complexdata));

//Use JSON to retrieve the stored data and convert it 
var storedData = sessionStorage.getItem("complexdata");
if (storedData) {
  complexdata = JSON.parse(storedData);
}

To remove sessionStorage Datas after using use sessionStorage.clear();

You can try this

declare variable on first page

<script type="text/javascript">
    var globalarray = [];
    globalarray.push(response.d);
     window.localStorage.setItem("globalarray", JSON.stringify(globalarray));
</script>

Call that variable on second page

<script type="text/javascript">
         var globalarray = [];
         var arrLinks =[];
         arrLinks = JSON.parse(window.localStorage.getItem("globalarray"));
        console.log(arrLinks);
</script>
