How To Add And Remove Textbox Dynamically In Javascript

In this article, you will learn how to dynamically add and remove textboxes using JavaScript.

This dynamic functionality can be incredibly useful when you want to allow users to add more input fields as needed, providing a flexible and user-friendly interface.

Method 1: Using the appendChild() Method #

To add textboxes dynamically, you can utilize the appendChild() method to create and insert new textbox elements within a container div.

Explanation of the above example :

1. Create the HTML Container: Create a container element that will hold the dynamically generated textboxes.
2. Add an Event Listener: Attach an event listener to a button or any other trigger element that users can click to add a new textbox.
3. Create and Append Textbox: Within the event listener, create a new textbox element using createElement() method. Customize its attributes, such as type, name, and placeholder. Then, use the appendChild() method to add the newly created textbox to the container.

Remove Textbox Using the removeChild() Method #

To remove textboxes dynamically, you can use the removeChild() method to delete specific textbox elements from the container.

Explanation of the above example :

1. Create the HTML Container: Similar to Method 1, create a container element to hold the textboxes.
2. Add Event Listeners: For each textbox, attach an event listener to a delete button or icon. This listener will trigger the removal of the corresponding textbox.
3. Identify Target to Remove: Within the event listener, identify the textbox you want to remove using DOM traversal techniques.
4. Use removeChild(): Once the target textbox is identified, use the parent container's removeChild() method to remove the textbox from the DOM.

Conclusion: #

In this article, you've learned two methods to dynamically add and remove textboxes using JavaScript.

The first method involves using the appendChild() method to add textboxes to a container, and the second method uses the removeChild() method to delete specific textboxes.
