Android browsers not handling touchmove events correctly

问题 When I try to inspect the touchmove event in this jsbin demo it only triggers once in Chrome and Opera for Android, and immediately after that, it triggers a touchcancel event, instead of continuing to trigger touchmove events? Based on both the W3C specs, and the behaviour of the touchmove event in both Firefox for Android and Android's default browser, it seems to me that the way the touch events are supposed to work is that the touchmove event keeps triggering while the touch is still on

How to synchronize the scroll offset of two elements during inertial scrolling

荒凉一梦 提交于 2019-12-07 01:13:42
问题 I need to keep the scroll offset of an element in sync with another (the window actually) and I'm having trouble doing so during the inertial "roll off" phase of scrolling on Mobile Safari (iPad). I have a couple of divs with position:fixed; overflow:hidden and I need to keep their scroll offset in sync with the window's one (meaning the entire body scroll.) Usually I'd code it like this (jQuery): var $win = $(window), $div1 = $(...) $win.scroll(function() { $div1.scrollTop($win.scrollTop())

问题 I would like to add some multitouch features to my javascript application when it is accessed from an ios device (and maybe android later). I want to provide a shiftkey-like functionality: the user may hold a button on the screen with one finger, and while this button is pressed, the behavior for a tap action on the rest of the screen is slightly different from the classic tap. The problem i'm running into is that i do not receive any touchend event for the tapping finger unless a touchmove

click and hold to scroll, touchstart, touchmove, touchend

I have a scrollable div. I want people to be able to scroll the list through 'hold', and also select a button for click. The problem is that when a button is held in order to scroll the div, it is triggering the click function. I want that do not trigger when scrolling. I need some way to differentiate click of the hold function. So I'm using: $('.panel').bind("touchstart mousedown", function (e) { console.log(e.type); $(this).addClass('resize'); }).bind("touchmove mousemove", function (e) { $(this).removeClass('resize'); }).bind("touchend mouseup", function (e) { $(this).removeClass('resize')

Because the screen is very sensitive,

I'm developing a game for iPhone using COCOS2D . In that, I need to draw a line when user drag his finger from a point to another.

When to use touchmove vs mousemove?

问题 I build a web mobile game, it runs on browsers (PC/Mobile). Do I need to use the touchmove or not? How can I run the touchmove event like the mousemove event? 回答1: For parity between desktop and touch you have the following equivalences: mousedown === touchstart mousemove === touchmove mouseup === touchend Thus if you handle mousedown, mousemove and mouseup then you don't need to handle the corresponding equivalent events under touch. The same handlers should be executing. 回答2: Except on the

JavaScript DOM changes in touchmove delayed until scroll ends on mobile Safari

北战南征 提交于 2019-11-28 04:25:00
In mobile safari, in the course of handling touchmove for an element, I change the className of that element. Unfortunately, the visual change does not occur while the user is scrolling, or until the very end of an inertial scroll. What can I do to get the className to visually take immediately? More: Apparently this isn't limited to className changes, but seemingly any change to the DOM, such as innerHTML and style . This is by design unfortunately. iOS safari will queue up all DOM manipulation until the end of a scroll or gesture. Effectively the DOM is frozen during a scroll. I thought I

Can't prevent `touchmove` from scrolling window on iOS

六月ゝ 毕业季﹏ 提交于 2019-11-27 20:06:16
We are trying to scroll an element on our iOS web app while preventing the window itself from scrolling. We are capturing the touchmove event on the window, scrolling the element programmatically and (trying to) prevent the window itself from scroll by calling preventDefault on the event. Unfortunately this doesn't work in Mobile Safari. The window continues to scroll underneath our element. The issue sounds exactly like the Webkit bug described in https://bugs.webkit.org/show_bug.cgi?id=163207 , but that issue was supposedly fixed in iOS 10.3 whereas I am running 11.3. Catching
