javascript and dragging in firefox

问题

I am writing a script to scroll a div container with javascript. Unfortunately it is not working that well in firefox. In firefox the stop-icon appears next to the cursor once I start dragging the knob and then my script is not able to get the mouseup-event.

Does anyone have an idea how to fix this?

回答1:

Check that mousemove event attached to document or window and not to the .knob element.

For those looking for a fix to a stop icon blocking the mouseup event (as I was when I found this post) I asked the question too, and finally found the answer myself which is here : **SOLVED** Click and drag on links in Firefox are blocking mouseup events

here is the JS code, everything is more detail on the question

const links = document.querySelectorAll('a');
links.forEach(element => {element.addEventListener('mousedown',function(e) { 
  e.preventDefault();
})
})
