Javascript - How to fetch data from mySQL and view in Modal

To fetch data from MySQL and display it in a modal using JavaScript, you'll typically follow these steps:

  1. Set up a backend server to handle MySQL database queries.
  2. Create a frontend interface to trigger fetching data and displaying it in a modal.
  3. Use AJAX or fetch API to communicate with the backend and fetch the data.
  4. Render the fetched data in a modal on the frontend.

Here's a basic example using JavaScript, PHP, and MySQL:

  1. Backend (PHP): Create a PHP script to handle the database query.
<?php // Assuming you have established a MySQL connection $connection = mysqli_connect("localhost", "username", "password", "database"); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); exit(); } // Perform SQL query $result = mysqli_query($connection, "SELECT * FROM your_table"); $data = mysqli_fetch_all($result, MYSQLI_ASSOC); // Return the data as JSON echo json_encode($data); // Close connection mysqli_close($connection); ?>
  1. Frontend (JavaScript): Use AJAX to fetch data from the backend and display it in a modal.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Modal Example</title> <!-- Include necessary CSS and JavaScript files --> </head> <body> <button id="openModalBtn">Open Modal</button> <!-- Modal --> <div id="myModal" class="modal"> <div class="modal-content"> <span class="close">&times;</span> <ul id="dataList"></ul> </div> </div> <script> // Function to fetch data from backend and display in modal function fetchDataAndDisplayModal() { // Make AJAX request to fetch data from backend fetch('backend.php') .then(response => response.json()) .then(data => { // Process the fetched data const dataList = document.getElementById('dataList'); dataList.innerHTML = ''; // Clear previous data data.forEach(item => { const li = document.createElement('li'); li.textContent = `${item.id}: ${item.name}`; // Example: Display id and name dataList.appendChild(li); }); // Display modal const modal = document.getElementById('myModal'); modal.style.display = "block"; }) .catch(error => { console.error('Error fetching data:', error); }); } // Open modal button click event handler document.getElementById('openModalBtn').addEventListener('click', fetchDataAndDisplayModal); // Close modal event handler document.getElementsByClassName('close')[0].addEventListener('click', function() { const modal = document.getElementById('myModal'); modal.style.display = "none"; }); </script> </body> </html>

In this example:

  • When the user clicks the "Open Modal" button, it triggers the fetchDataAndDisplayModal function.
  • This function makes an AJAX request to the PHP backend (backend.php) to fetch data from MySQL.
  • Upon successful retrieval of data, it updates the HTML content of the modal with the fetched data and displays the modal.
  • The modal is closed when the user clicks the close button (&times;).

Examples

  1. "Fetch MySQL data and display in modal using JavaScript"

    • Users may want to retrieve data from a MySQL database and display it dynamically in a modal using JavaScript.
