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.



Fired when a static <script> element  finishes executing its script. Does not fire if the element is added dynamically, eg with appendChild().


document.onafterscriptexecute = funcRef;

funcRef is a function reference, called when the event is fired. The event's target attribute is set to the script Element that just finished executing.


function finished(e) {
  logMessage("Finished script with ID: " +;

document.addEventListener("afterscriptexecute", finished, true);
