Signature

getContextHtml(el: HTMLElement): : string | null

Summary

Extracts the relevant surrounding container HTML for a field element. Walks up the DOM looking for a wrapping label, fieldset or common form-group patterns. Returns null when none is found.

Source Code

function getContextHtml(el: HTMLElement): string | null {
  const container =
    el.closest<HTMLElement>(
      'label, fieldset, [class*="field"], [class*="group"], [class*="form-"], [class*="input-wrap"]',
    ) ?? el.parentElement;

  if (!container || container === el) return null;

  // Avoid returning the entire <form> or <body>
  if (
    container.tagName === "FORM" ||
    container.tagName === "BODY" ||
    container.tagName === "MAIN"
  ) {
    return null;
  }

  const raw = container.outerHTML;
  if (raw.length <= MAX_CONTEXT_HTML_CHARS) return raw;
  return raw.slice(0, MAX_CONTEXT_HTML_CHARS) + "…";
}
