Is called only once, on start of scroll but I want to break scroll that is in progress. It's possible to do this in different way that not need to override scrollWheel method? 来源： https://stackoverflow.com

问题 Is there a way to trigger a scroll wheel event with an arbitrary delta. Just like jQuery does with 'click' like: $('#selector').trigger('click'); I need something like that just with an scrollwheel like: $('#selector').trigger('DOMMouseScroll',{delta: -650}); //or mousewheel for other browsers I can't do anything like 'fake it' with css trickery, I need to trigger the actual native (or as close as possible) event.

I am working on a WordPress site where the authors usually embed Google Maps using iFrames in most posts. Is there a way to disable the zoom via mouse scroll wheel on all of them using Javascript? Massa I was having the same problem: when scrolling the page then the pointer becomes over the map, it starts to zoom in/out the map instead of continuing scrolling the page. :( So I solved this putting a div with an .overlay exactly before each gmap iframe insertion, see: <html> <div class="overlay" onClick="style.pointerEvents='none'"></div> <iframe src="https://mapsengine.google.com/map/embed?mid
