Window: DOMContentLoaded event - Web APIs 编辑

The DOMContentLoaded event fires when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading.

The original target for this event is the Document that has loaded. You can listen for this event on the Window interface to handle it in the capture or bubbling phases. For full details on this event please see the page on the Document: DOMContentLoaded event.

A different event, load, should be used only to detect a fully-loaded page. It is a common mistake to use load where DOMContentLoaded would be more appropriate.

Examples

Basic usage

window.addEventListener('DOMContentLoaded', (event) => {
    console.log('DOM fully loaded and parsed');
});

Specifications
