How to define a mouseDown event.button before the event is trigerred

Question

I have this error and I just don't know how to get ride of it.
I can add info if you want.
Bellow error and code.

////////error
Uncaught TypeError: Cannot read property 'button' of undefined
at mouseDown (renderer.js:303)
at index.html:196
////////////code
function mouseDown(e, imgs) {
if (e.button == 0) {///some code}

Answer 1

What is the use of <imgs> argument of mouseDown function? I thought event handler functions supposedly take one argument only (the event)? not too sure though,

Have you checked what <e> argument actually is in the console?

How did you bind the event with the element?

Answer 2

The event work perfectly in itself, and you can convey as much as you want info in it. And this is essential in electron. The clicked buttons works fine when they are clicked, but before then... there is this error.

Answer 3

I stopped to dev. Thanks for the help Tashi N san. I moved forwared.

Answer 4

So the event is mapped fine, but error is still coming? that's odd.

I'd suggest to either keep this thread open for further response, or delete it, and create a new thread with complete code attached, in a hope someone can help you out after reading the full version of the code.

You can save the code in SoloLearn (as code bit) and share its link in thread Description following this guide
