JS: Touch equivalent for mouseenter

Question

is there a touch equivalent of the mouseenter.

I would like to detect if user slide on my DIV.

I prefer a solution depending directly on the target element not on a parent element with recounting positions etc.

The site: http://dizzyn.github.io/piano-game/ - works fine with mouse (mouse down and slide; not working with touch slide)

Thank you

Look into these events:

touchstart Triggers when the user makes contact with the touch surface and creates a touch point inside the element the event is bound to.

touchmove Triggers when the user moves the touch point across the touch surface.

touchend Triggers when the user removes a touch point from the surface. It fires regardless of whether the touch point is removed while inside the bound-to element, or outside, such as if the user's finger slides out of the element first or even off the edge of the screen.

touchenter Triggers when the touch point enters the bound-to element. This event does not bubble.

touchleave Triggers when the touch point leaves the bound-to element. This event does not bubble.

touchcancel Triggers when the touch point no longer registers on the touch surface. This can occur if the user has moved the touch point outside the browser UI or into a plugin, for example, or if an alert modal pops up.

Specifically touchenter and touchleave.

2019: Yes-ish: Using pointerenter.

By default, a touch causes a browser to 'capture' the pointer such that following events are scoped to that touched element. This prevents pointerleave/enter events, unless you explicitly release the capture. Moreover, you'll want to set touch-action:none on relevant elements to avoid the browser intercepting touches for default pan/zoom etc.

Example:

CSS:

*{ touch-action: none; }   

JS:

let div = document.querySelector("div") div.addEventListener("pointerdown",(e)=>{     console.log("down")     console.log("attempt release implicit capture")     div.releasePointerCapture(e.pointerId) // <- Important! }) div.addEventListener("pointerenter",(e)=>{     console.log("enter") }) div.addEventListener("pointerleave",(e)=>{     console.log("leave") }) 

Works in Chrome at least. Not so much in Mobile Safari 13 beta though... According to the w3c specs, I'm fairly certain it should work this way. Maybe when iOS 13 is officially released we'll be in the clear. [I've filed a bug and looks like it's being attended to.]

[Update: iOS 13 issue fixed. Should work in Chrome/FF/Safari]
