The importScripts()
method of the WorkerGlobalScope
interface synchronously imports one or more scripts into the worker's scope.
WorkerGlobalScope.importScripts()
Syntax
self.importScripts('foo.js'); self.importScripts('foo.js', 'bar.js', ...);
Parameters
A comma-separated list of DOMString
objects representing the scripts to be imported. These paths are relative to html document base URL.
Return value
None.
Exceptions
-
NetworkError
-
Imported scripts were served without a
text/javascript
MIME type or without one of the permitted legacy JavaScript MIME types.
Example
If you had some functionality written in a separate script called foo.js
that you wanted to use inside worker.js, you could import it using the following line:
importScripts('foo.js');
importScripts()
and self.importScripts()
are effectively equivalent — both represent importScripts()
being called from inside the worker's inner scope.
