To get the current mouse position we are going to trigger a mouse event. So how can we get the mouse position from a mouse event? Getting the current X and Y coordinates from an event
As far as I’m aware it isn’t possible to get the current mouse position without triggering a mouse event. I would usually include some catch like ‘get the current mouse position without using an event’. This simple problem was something I found myself googling fairly often when I was new to coding. To do all of these things you need to know the current mouse position relative to the screen.
MouseEvent, the interface of the objects it constructs.Would you like to be able to open a modal, or a context menu? Maybe you are making a browser game, or simply adding a sparkly trail to your mouse. MouseEventPolyfill.prototype = Event.prototype Var mouseEvent = document.createEvent('MouseEvent') You can polyfill the MouseEvent() constructor functionality in Internet Explorer 9 and higher with the following code: (function (window) User must explicitly enable this feature.

Notes Disabled Notes Flag needed to retrieve value from MouseEvent.region. In some implementations, passing anything other than a number for the screen and client fields will throw a TypeError. The absence of any hit region is affected, is represented by the null value. "region", optional and defaulting to null, of type DOMString, is the id of the hit region affected by the event."relatedTarget", optional and defaulting to null, of type EventTarget, that is the element just left (in case of a mouseenter or mouseover) or is entering (in case of a mouseout or mouseleave).Main button pressed (usually the left button) "buttons", optional and defaulting to 0, of type unsigned short, that describes which buttons are pressed when the event is launched:.Secondary button pressed (usually the right button)
Main button pressed (usually the left button) or un-initializedĪuxiliary button pressed (usually the middle button)
"button", optional and defaulting to 0, of type short, that describes which button is pressed during events related to the press or release of a button:. "metaKey", optional and defaulting to false, of type Boolean, that indicates if the meta key was simultaneously pressed. "altKey", optional and defaulting to false, of type Boolean, that indicates if the alt key was simultaneously pressed. "shiftKey", optional and defaulting to false, of type Boolean, that indicates if the shift key was simultaneously pressed. "ctrlKey", optional and defaulting to false, of type Boolean, that indicates if the ctrl key was simultaneously pressed. "clientY", optional and defaulting to 0, of type long, that is the vertical position of the mouse event on the client window of the user's screen setting this value doesn't move the mouse pointer. "clientX", optional and defaulting to 0, of type long, that is the horizontal position of the mouse event on the client window of user's screen setting this value doesn't move the mouse pointer. "screenY", optional and defaulting to 0, of type long, that is the vertical position of the mouse event on the user's screen setting this value doesn't move the mouse pointer. "screenX", optional and defaulting to 0, of type long, that is the horizontal position of the mouse event on the user's screen setting this value doesn't move the mouse pointer. mouseEventInit Optional Is a MouseEventInit dictionary, having the following fields: Syntax event = new MouseEvent( typeArg, mouseEventInit) Values typeArg Is a DOMString representing the name of the event. The MouseEvent() constructor creates a new MouseEvent.
