Dynamic Form Group Cloning Library – Repeater-Field.js

Repeater-Field.js is a lightweight JavaScript library for dynamically generating HTML forms where your users can duplicate form fields or form groups with a single click.

How to use it:

1. Download and load the repeater-field.js library.

<script src="repeater-field.js"></script>

2. Create a container to hold the HTML form.

<div id="repeater-field-container"></div>

3. Initialize the library to generate a basic HTML form containing an input field and a duplicate button.

const container = document.getElementById("repeater-field-container");
const repeaterField = new RepeaterField(container);

4. Generate an HTML form from user predefined data as follows:

const repeaterField = new RepeaterField(container,{
      data: [
        ["CSSScript", "2013-04-15", "A JavaScript/CSS Website"],
        ["", "", ""]
      ],
      fields: {
        row: {
          classList: [
            "my-repeater-row"
          ]
        },
        inputs: [
          {
            type: "text",
            name: "name",
            placeholder: "Name of the person..."
          },
          {
            type: "date",
            name: "dob"
          },
          {
            type: "textarea",
            name: "about",
            placeholder: "About the person...",
            wrapper: {
              element: "div"
            }
          }
        ]
      },
});

5. Customize the Duplicate & Remove buttons.

const repeaterField = new RepeaterField(container,{
      deleteButton: {
        value: "Delete person",
        classList: ["my-delete-button"]
      },
      addButton: {
        value: "Add person",
        classList: ["my-add-button"]
      }
});
