In this tutorial we will create a Submit Multiple Fields using JavaScript. This code will dynamically insert a multiple you array of form fields when the user click the insert button. The code use onclick() to call a method that can insert a multiple form fields with the use of for() loop to repeatedly insert the inputs base on the length of the array index. You can apply this script to your code to make your transaction faster, it is a user-friendly program feel free to modify it.
We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user.
Getting Started:
This is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.
