How to Parse JSON Data with jQuery / JavaScript 🤔

JSON (JavaScript Object Notation) is a popular data format used for transmitting and storing structured data. It is widely supported by various programming languages, including JavaScript.

In this blog post, we will address a common question: How can I loop through JSON data and place each name in a div? We will provide you with easy solutions and examples using jQuery and JavaScript.

Understanding the JSON Data 📚

Let's take a closer look at the JSON data returned by the AJAX call:

[ 
  { "id" : "1", "name" : "test1" },
  { "id" : "2", "name" : "test2" },
  { "id" : "3", "name" : "test3" },
  { "id" : "4", "name" : "test4" },
  { "id" : "5", "name" : "test5" } 
]

This data represents an array of objects. Each object contains two properties: id and name. To loop through this data and extract the name property, we can use jQuery or JavaScript.

Parsing JSON Data with jQuery 🔍

To parse JSON data with jQuery, we can make use of the $.each() function. Here's an example of how to loop through the JSON data and place each name in a div:

$(document).ready(function() {
  $.ajax({
    type: 'GET',
    url: 'http://example/functions.php',
    data: { get_param: 'value' },
    success: function(data) {
      var jsonData = JSON.parse(data); // Parse the JSON data

      $.each(jsonData, function(index, object) {
        var name = object.name; // Extract the name property

        // Create a div and append the name
        var div = $('<div>').text(name);
        $('#cand').append(div);
      });
    }
  });
});

In the example above, we first parse the JSON data using JSON.parse(). This converts the JSON string into a JavaScript object, allowing us to easily access its properties. We then use the $.each() function to iterate over each object in the array. Inside the loop, we extract the name property and create a div element with that name. Finally, we append the div element to the #cand div.

Parsing JSON Data with JavaScript 🌐

If you prefer to use plain JavaScript, you can achieve the same result using the forEach() method. Here's an example:

document.addEventListener('DOMContentLoaded', function() {
  var xhr = new XMLHttpRequest();
  xhr.open('GET', 'http://example/functions.php?get_param=value', true);
  xhr.onload = function() {
    if (xhr.status === 200) {
      var jsonData = JSON.parse(xhr.responseText); // Parse the JSON data

      jsonData.forEach(function(object) {
        var name = object.name; // Extract the name property

        // Create a div and append the name
        var div = document.createElement('div');
        div.textContent = name;
        document.getElementById('cand').appendChild(div);
      });
    }
  };
  xhr.send();
});

In this JavaScript example, we create an XMLHttpRequest object to fetch the JSON data. Once the data is fetched, we parse it using JSON.parse() and iterate over each object using forEach(). Inside the loop, we extract the name property and create a div element with that name. Finally, we append the div element to the #cand div.
