I don’t know if this is a mistake if I am doing something wrong or is it just normal HammerJS behavior, but I am trying to use HammerJS to create a slide menu (Facebook style) for the application I'm developing with Cordova.
So far, everything is working fine for me, except for one: HammerJS kills the native -webkit-overflow-scroll: touch;children of the element to which HammerJS is attached. I talked to juste about all the options that I could find in the document, but didn't seem to be able to get this to work.
Any ideas?
Here is my coffescript code
Hammer($page, {
transform_always_block: false,
drag_block_horizontal: false,
drag_block_vertical:false
})
.on('dragstart', (event)->
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(->
