我不知道这是否是错误，是否做错了或者这仅仅是HammerJS的正常行为，但是我试图使用HammerJS为我正在使用Cordova开发的应用制作滑出菜单(Facebook风格) 。
到目前为止，除一种功能外，我一切正常:HammerJS杀死附加了HammerJS的元素的子元素的本地-webkit-overflow-scroll: touch;。我在文档中找到了所有可以找到的选项，但都无法解决这个问题。
有任何想法吗 ？
这是我的咖啡代码
Hammer($page, {
transform_always_block: false,
drag_block_horizontal: false,
drag_block_vertical:false
})
.on('dragstart', (event)->
#event.gesture.preventDefault()
#event.gesture.stopPropagation()
direction = event.gesture.direction
$mainMenu.show()
$('.UIViewContainer').css(overflow: 'hidden')
if direction is 'left'
$('#homeDisableOverlay').animate({
opacity: 0
}, 500, 'ease', ->
$(@).hide()
)
)
.on('dragright', (event)->
event.gesture.stopPropagation()
direction = event.gesture.direction
offsetLeft = $page.offset().left
scaleMenu = 0.9 + scaleStep * offsetLeft
if scaleMenu > 1
scaleMenu = 1
if scaleMenu < 0.9
scaleMenu = 0.9
if((offsetLeft > sidebarOffset) or (!App.PageDrag)) then return false
if !App.sidebar
offset = event.gesture.deltaX
if offset > sidebarOffset then offset = sidebarOffset
$page.animate({ translate3d: offset + 'px, 0, 0'}, 0)
$mainMenuTable.animate({ scale: scaleMenu}, 0)
)
.on('dragleft', (event)->
event.gesture.stopPropagation()
event.stopPropagation()
console.log direction
offsetLeft = $page.offset().left
scaleMenu = 0.9 + scaleStep * offsetLeft
if scaleMenu > 1
scaleMenu = 1
if scaleMenu < 0.9
scaleMenu = 0.9
if((offsetLeft <= 0) or (!App.PageDrag)) then return false
if App.sidebar
offset = sidebarOffset + event.gesture.deltaX
if offset < 0 then offset = 0
$page.animate({ translate3d: offset + 'px, 0, 0'}, 0)
$mainMenuTable.animate({ scale: scaleMenu}, 0)
)
.on('dragend', (event)->
event.gesture.stopDetect()
event.gesture.preventDefault()
event.gesture.stopPropagation()
speed = 300 / event.gesture.velocityX
if speed > 300 then speed = 300
if(event.gesture.direction is 'right' and !App.sidebar)
if((event.gesture.deltaX > sidebarOffset/2) or (event.gesture.velocityX > 0.4))
$page.animate({ translate3d: sidebarOffset + 'px, 0, 0'}, speed, 'ease')
$mainMenuTable.animate({ scale: 1}, speed, 'ease')
App.sidebar = true
$('#homeDisableOverlay').show().animate({
opacity: 0.3
}, 200, 'ease')
else
$page.animate({ translate3d: '0, 0, 0'}, 200, 'ease')
$mainMenuTable.animate({ scale: 1}, 200, 'ease')
$('.UIViewContainer').css(overflow: 'hidden')
scaleMenu = 1
else
if((event.gesture.deltaX < sidebarOffset/2) or (event.gesture.velocityX > 0.4))
$page.animate({ translate3d: '0, 0, 0'}, speed, 'ease')
$mainMenuTable.animate({ scale: 0.9}, speed, 'ease')
App.sidebar = false
setTimeout(->
document.getElementById('mainMenuScroll').scrollTop = 0
,speed)
else
$page.animate({ translate3d: sidebarOffset + 'px, 0, 0'}, 200, 'ease')
$mainMenuTable.animate({ scale: 0.9}, 200, 'ease')
setTimeout(->
document.getElementById('mainMenuScroll').scrollTop = 0
,200)
$('.UIViewContainer').css(overflow: 'auto')
scaleMenu = 0.9
)
最佳答案
是的，这显然是HammerJS的预期行为:

我目前正在尝试寻找一种替代方法，以使捏合手势在全局范围内运行而又不会破坏iOS上的滚动。
