The HTML component allows you to insert custom HTML content into your survey. This is useful for adding rich text, images, videos, or any other HTML elements that are not covered by the standard question types.

​
Basic Usage

const welcomeMessage = new HTML({
    id: 'welcome',
    content: '<h2>Welcome to our survey!</h2><p>Thank you for participating.</p>'
});

​

​
id
string

​

​
styles

The HTML component inherits methods from the base Element class, but most are not applicable as it doesn’t collect data. Here are some key methods:
​
validate
function
Always returns an object indicating valid status as HTML components don’t require validation.Returns:
  • An object with isValid (boolean) set to true and an empty errorMessage string.
const { isValid, errorMessage } = htmlComponent.validate();
// isValid will always be true, errorMessage will be an empty string
​
generateHTML
function
Generates the HTML structure for the component.Returns:
  • string: The generated HTML
const htmlString = htmlComponent.generateHTML();
​
render
function
Renders the HTML content or updates it if already rendered.Parameters:
  • surveyElementStyles (object): Styles to be applied from the survey level
htmlComponent.render(surveyStyles);
​
destroy
function
Removes the HTML content from the DOM.
htmlComponent.destroy();

​
Example

Here’s an example of how to create a more complex HTML component: 
const complexContent = new HTML({
    id: 'instructions',
    content: `
        <div class="instructions">
            <h3>Survey Instructions</h3>
            <ol>
                <li>Read each question carefully</li>
                <li>Answer honestly</li>
                <li>Take your time</li>
            </ol>
            <img src="survey-image.jpg" alt="Survey illustration">
        </div>
    `,
    styles: {
        root: {
            backgroundColor: '#f0f8ff',
            padding: '15px',
            borderRadius: '8px',
            boxShadow: '0 2px 4px rgba(0,0,0,0.1)'
        },
        // Other style keys inherited from Element class can be used here
    }
});
