Import a javascript file and call the function within it

Question

I have this file: a.js

export function work(){
    // do stuff
}

And this jsp file:

...
<script type="text/javascript" src='<c:url value="/javascripts/a.js"/>'></script>
...

How do I call the function "work" from my jsp file? It always says "work is not defined"

Attempted (deeper in the jsp):

...
    <th><a href="#" onclick="return work();" > Work # </a></th>
...

Have you tried "return window.work();"? Since the script is in the HEAD, the DOM may not be initialized yet. You may need to listen for DOMContentLoaded. — Mr. Polywhirl

href="#" — if you're linking to the top of the page then you probably shouldn't be using a link and should be using a <button> instead. — Quentin

This might help if you still want to use modules. stackoverflow.com/questions/44590393/… — Yury Tarabanko

export is only supported in ES6 modules, and you aren't loading the JS file as a module.

Remove the export keyword.

(If you were loading it as a module <script src="..." type="module"></script> then work wouldn't be a global so you couldn't call it from an on* attribute anyway).

you don't need to export the function if you linking the file then remove the return and the href and replce the with a button it's better:

<th><<button onclick="work();" > Work # </button></th>
