The domComplete read-only property returns a DOMHighResTimeStamp representing the time immediately before the user agent sets the document's readyState to "complete".

See also the complete state of Document.readyState which corresponds to this property and refers to the state in which the document and all sub-resources have finished loading. The state also indicates that the load event is about to fire.

A DOMHighResTimeStamp representing the time immediately before the user agent sets the document's readyState to "complete".

The domComplete property can be used to log the time when the DOM is complete.

Example using a PerformanceObserver, which notifies of new navigation performance entries as they are recorded in the browser's performance timeline. Use the buffered option to access entries from before the observer creation.

const observer = new PerformanceObserver((list) => {
  list.getEntries().forEach((entry) => {
    console.log(`${entry.name}: domComplete time: ${entry.domComplete}ms`);
  });
});

observer.observe({ type: "navigation", buffered: true });

Example using Performance.getEntriesByType(), which only shows navigation performance entries present in the browser's performance timeline at the time you call this method:

const entries = performance.getEntriesByType("navigation");
entries.forEach((entry) => {
  console.log(`${entry.name}: domComplete time: ${entry.domComplete}ms`);
});
