In this article, we will select values from a JSON object and display them on the browser using jQuery. To select values from a JSON object to webpage, we use append() method. 

This append() method in jQuery is used to insert some content at the end of the selected elements.

Syntax:

$(selector).append( content, function(index, html) )

Approach: First we store a JSON object containing (key, value) pair in a variable. We have created a button using <button> element and when we click the button, the jQuery function called with selector and click events. After click the button, the attr() method added the name attribute with <select> element. The <option> element is appended to each element using append() and each() methods.

Example:

HTML 
<!DOCTYPE html>
<html lang="en">

<head>
    <title>

    <!-- Import jQuery cdn library -->
    <script src=
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
    </script>

    <script>
        $(document).ready(function () {

            var json = [
                { "name": "GFG", "text": "GFG" },
                { "name": "Geeks", "text": "Geeks" },
                { "name": "GeeksforGeeks", 
                    "text": "GeeksforGeeks" }
            ];

            $('button').click(function () {
                var select = $("<select></select>")
                    .attr("name", "cities");

                $.each(json, function (index, json) {
                    select.append($("<option></option>")
                    .attr("value", json.name).text(json.text));
                });
                $("#GFG").html(select);
            });
        });  
    </script>
</head>

<body style="text-align: center;">
