Document.currentScript
Returns the <script>
element whose script is currently being processed.
Syntax
JavaScript
Copy Code
var <var>curScriptElement</var> = document.currentScript;
Example
This example checks to see if the script is being executed asynchronously:
JavaScript
Copy Code
if (document.currentScript.async) { console.log("Executing asynchronously"); } else { console.log("Executing synchronously"); }
Notes
It's important to note that this will not reference the <script>
element if the code in the script is being called as a callback or event handler; it will only reference the element while it's initially being processed.
