How to Retrieve Values from Multiple Textboxes with jQuery on Keyup
In modern web development, efficiently handling user input is crucial for creating responsive and dynamic user interactions. One common requirement is retrieving values from multiple textboxes in real-time as users type. In this post, we'll explore how you can leverage the power of jQuery to accomplish this task using the keyup event.
Understanding the keyup Event
The keyup event is triggered when the user releases a key on the keyboard. By attaching a keyup event handler to your textboxes, you can execute code every time the user types, allowing you to dynamically fetch and utilize the input values.
Setting Up Your HTML
Before diving into the jQuery code, let's create a simple HTML structure with multiple textboxes:

jQuery Implementation
Let's break down the jQuery implementation from the script tag:
Document Ready: We ensure that the DOM is fully loaded before attaching event handlers by using $(document).ready(function(){ ... });.
Event Handling: We use $('.textbox').keyup(function(){ ... }); to attach the keyup event to all textboxes with the class textbox.
Retrieve Values: Inside the event handler, we declare an empty array values. By iterating over each textbox using $('.textbox').each(function(){ ... });, we push the current value of each textbox into the values array using values.push($(this).val());.
Display Results: Finally, we update the output div with the concatenated values by using $('output').text('Values: ' + values.join(', '));.
Conclusion
By using jQuery's keyup event, you can efficiently retrieve and handle values from multiple textboxes in real-time. This approach not only enhances the user experience but also provides a clean and manageable way to handle dynamic input.
