I need to know if the button to draw points on this map ...
https://bl.ocks.org/danswick/083a0b48c2cc78c4a08d
is clicked.
I've tried to use this Javascript code ..
var editButton = document.getElementsByClassName('mapbox-gl-draw_ctrl-draw-btn mapbox-gl-draw_point'); // grab a reference to your element
editButton.onclick = function(){
alert("Clicked!");
}
... but nothing happens (no error ... ).
If I try to check for the editButton variable value in my Chrome console I can see that it's a HTMLCollection[1], so not empty ...
Suggestions / example / alternatives?

document.getElementsByClassName
returns a collection. You need to set the click handler for the actual element.
var elements = document.getElementsByClassName('mapbox-gl-draw_ctrl-draw-btn mapbox-gl-draw_point');
var editButton = elements[0];
