Embed Library

Introduction

You can use Formcrafts’ embed library @formcrafts/embed to embed forms using vanilla JavaScript. The library is available as an npm package, and works well with frameworks like Svelte, React, Vue, and Angular.

Installation

To add the Formcrafts JavaScript library to your project, install it using npm:

npm install @formcrafts/embed --save

Importing the library

To make the library available in your code, import the necessary modules:

import { createInlineForm, createPopup } from "@formcrafts/embed";

Embed - Inline

Initialize the form

const myInlineForm = await createInlineForm({
	form: "form_key", // Your form key
	target: document.getElementById("element_id"), // Target element
	seamless: true, // Removes form border, shadow, and padding
	width: 500, // Max width of the form
	redirectWithin: true, // Keep redirect within form frame
	values: {
		field1: "Jack Smith",
		field2: ["Chocolate", "Vanilla"]
	} // Prefill values
});

Available methods

You can use the following methods to interact with the popup form:

myInlineForm.on("load", (height: number) => {}); // Fires when the form loads
myInlineForm.destroy(); // Remove the form instance
myInlineForm.values({
	field1: "New value"
}); // Update the values of the form

The values method should be called after the load event. The values method can also be used to update utm_parameters, as such:

myInlineForm.values({
	utm_source: "google",
	utm_medium: "cpc",
	utm_campaign: "summer_sale"
});

Embed - Popup

Initialize the form

const myPopupForm = await createPopup({
	form: "form_key", // Your form key
	width: 500, // Max width of the form
	redirectWithin: true, // Keep redirect within form frame
	values: {
		field1: "Jack Smith",
		field2: ["Chocolate", "Vanilla"]
	} // Prefill values
});

Available methods

You can use the following methods to interact with the embedded inline form:

myPopupForm.load(); // Load the form. Can be used to load the form before showing it. Optional.
myPopupForm.open(); // Open the popup
myPopupForm.close(); // Close the popup
myPopupForm.destroy(); // Destroy the popup and the form instance
myPopupForm.values({
	field1: "New value"
}); // Update the values of the form
