Document: afterscriptexecute event

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The afterscriptexecute event fires when a static <script> element finishes executing its script. It does not fire if the element is added dynamically, such as with appendChild().


Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("afterscriptexecute", (event) => {});

onafterscriptexecute = (event) => {};

Event type

A generic Event.


function finished(e) {
  logMessage(`Finished script with ID: ${}`);

document.addEventListener("afterscriptexecute", finished, true);
// or
document.onafterscriptexecute = finished;
