I am new to JavaScript so I might be missing something obvious here, but this is the problem. I am not getting the mouse down / up event if the event happened outside the active area under JavaScript control, so if the mouse enters the active area (onmouseover event) with the left button down, is there a way to know that the button is down?
Added info : Ideally, I would like to keep track of the mouse even outside the browser window – the way Google maps does – try clicking down the mouse button and move outside the browser – this works in chrome and with some quirks in Firefox. Is it possible to do this while remaining within the bounds of JavaScript or is it some proprietary stuff?
Yes: ensure that the mouse event handlers to detect a mouse-down event are attached to some element that occupies the entire viewport. For instance the HTML (document) element…
