[轉貼] JavaScript Touch and Gesture Events iPhone and Android
JavaScript Touch and Gesture Events iPhone and Android
There are quite a few sites that describe the touch and gesture events that can be used in the mobile version of WebKit running on iPhone and iPod Touch. There is, however, not so much info with regards to Android. I've placed a few links at the bottom of this article that contain information used to compile this brief explanation.
Touch events are a bit like mouse events, but there are some very important differences when it comes to touch vs. mouse:
A touch object contains pretty much the same data as a mouse event such as pageX, pageY etc...
Example:
Apples WebKit implementation has a few things that are different from the Android implementation. The touchEnd event removes the current touch from the
Example:
Touch events are a bit like mouse events, but there are some very important differences when it comes to touch vs. mouse:
- A touch is very hard to keep steady whilst a mouse can stay at a fixed position - this means that we go from a touchStart event directly to a touchMove event. Unlike a mouse where a mouseDown event is likely to fire without being followed up by a mouseMove event.
- There is no mouseOver equivalent since a touch can be discontinuous, i.e., we can get from point A to point B without the need of drawing a continuous line between these points.
- A touch is an averaged point taken from the surface area in contact with the pointing device (your finger) translated to pixel coordinates - like finding the centre of a circle. A mouse is very precise and there is no averaging that needs to be done. What I'm trying to say is that a touch is not as accurate as a mouse.
Android and iPhone touch events
Android and iPhone versions of WebKit have some touch events in common:- touchstart - triggered when a touch is initiated. Mouse equivalent - mouseDown
- touchmove - triggered when a touch moves. Mouse equivalent - mouseMove
- touchend - triggered when a touch ends. Mouse equivalent - mouseUp. This one is a bit special on the iPhone - see below
- touchcancel - bit of a mystery
document.addEventListener('touchstart', function(event) { alert(event.touches.length); }, false);
The Event object
As you may have noticed above, the event object contains an array called touches (in Androids case, the event object also containes a touch object - at this stage, touches has always a length of 1 in Android so event.touches[0] === event.touch). The touches array is Apples way of handling multi-touch events - but more on that later.A touch object contains pretty much the same data as a mouse event such as pageX, pageY etc...
Example:
document.addEventListener('touchmove', function(event) { event.preventDefault(); var touch = event.touches[0]; console.log("Touch x:" + touch.pageX + ", y:" + touch.pageY); }, false);
What about a click?
mouseClick events are triggered after a touchStart, touchEnd event sequence. A reason for mouseClick events not triggering can be that the event propagates further and a touchMove being initiated - this will cancel the mouseClick event sequence.iPhone Touch and Gesture Events
Apples WebKit implementation has a few things that are different from the Android implementation. The touchEnd event removes the current touch from the
event.touches array. Instead, we have to look inside the event.changedTouches array.Apples event object for touch events
The event object contains the following arrays:- touches - contains touch information upon touchStart and touchMove not touchEnd events
- targetTouches - contains information for touches originating from the same target element
- changedTouches - contains touch information upon all touch events
Gesture events
Apple supports gestures which are mult-touch events such as "pinching" and "rotating":- gesturestart - triggered when initiating a multi-touch event
- gesturechange - triggered when multiple touches move
- gestureend - triggered when a multi-touch event ends
Example:
document.addEventListener('gesturechange', function(event) { event.preventDefault(); console.log("Scale: " + event.scale + ", Rotation: " + event.rotation); }, false);
Event table
| touchstart | touchmove | touchend | gesturestart | gesturemove | gestureend | |
|---|---|---|---|---|---|---|
| Android | y | y | y | n | n | n |
| iPhone | y | y | y | y | y | y |
| has event.touches | y | y | y | n | n | n |
| (iPhone) has event.scale and event.rotation | n | n | n | y | y | y |
| (iPhone) touch in event.touches | y | y | n | - | - | - |
| (iPhone) touch in event.changedTouches | y | y | y | - | - | - |

7-11 賬單條碼規則
代收服務之電腦條碼及安全機制※條碼品質及規則：
一、 第一段條碼固定為9碼，前6碼為代收期限，後3碼為代收代號
二、 條碼固定為Code39碼，品質為C級以上，由7-11行銷作業人員檢測通過
三、 各段條碼由上而下依序排列，條碼間距請至少保留0.6公分，左右間距的空白長度一般為「X」dimension的10倍寬或1/4英吋，建議以約2公分為主。
四、 條碼長度不可超過6.2公分，英數字位數不超過20位，條碼高度建議在0.8公分至1.4公分左右，建議條碼寬窄比 2:5及印刷寬度愈大愈好。
五、 避免列印條碼為彩色或淺色系顏色，背景色(建議為白色空白)與條碼及空白間顏色的對比需明顯
六、 條碼前後需加起始字元*及結束字元*
七、 條碼區請加印「統一超商專用條碼區」以利辨視
八、 2-3段條碼欄位內容，英數字及長度依各代收項目規格設定
九、 條碼檢查碼計算方式依所指定公式計算。
Barcode：三段式條碼 (9+16+15)第一段(9) 繳費期限yymmdd (6) + 代收項目XXX(3)第二段(16) 業者自行訂定 (16)
第三段(15) 應繳日期mmdd (4) + 檢碼(2) + 應繳金額(9)
ps: 1.檢碼為”檢查碼公式一(二碼之校對碼公式)”
2.yymm為民國年月
3.帳單之唯一性以第二段條碼為依據(繳費證明單上查詢依據)
4.第二段條碼不足位數者，由位數小者補0
ps: 1.檢碼為”檢查碼公式一(二碼之校對碼公式)”
2.yymm為民國年月
3.帳單之唯一性以第二段條碼為依據(繳費證明單上查詢依據)
4.第二段條碼不足位數者，由位數小者補0
5.請說明第二段條碼編碼原則
校對碼計算：
附件: 校對碼公式一 (二碼校對碼的公式)
(1).Barcode中金額欄位之前二字元為全部條碼之檢查碼.
(2)若Barcode中有文字型態資料,則將其轉換成數值後計算
轉換Table
字母 | Ａ | Ｂ | Ｃ | Ｄ | Ｅ | Ｆ | Ｇ | Ｈ | Ｉ | Ｊ | Ｋ | Ｌ | Ｍ | Ｎ | Ｏ | Ｐ | Ｑ | Ｒ | Ｓ | Ｔ | Ｕ | Ｖ | Ｗ | Ｘ | Ｙ | Ｚ |
代碼 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
(3)校對碼之第一碼計算公式:
各段Barcode之’基數值’之加總值 除以11 後之’餘數’
(若餘數為0則放A,若餘數為10則放B)
各段Barcode之’基數值’之加總值 除以11 後之’餘數’
(若餘數為0則放A,若餘數為10則放B)
校對碼之第二碼算公式:
各段Barcode之’偶數值’之加總值 除以11 後之’餘數’
(若餘數為0 則放X, 若餘數為10則放Y)
各段Barcode之’偶數值’之加總值 除以11 後之’餘數’
(若餘數為0 則放X, 若餘數為10則放Y)
例: 有三段條碼,而Barcode3的後9碼為’金額“則**即為校對碼
Barcode1: 991231Y01
Barcode2: ABCDEFGHIKLMNPQR
Barcode3: 1234**000007890(本例不佳，因前4碼為MMDD，12月沒34日)
校對碼之第一碼計算
第一段積數位總和 (9+1+3+'Y':8+1) = 22
第二段積數位總和 ('A':1+'C':3+'E':5+'G':7+'I':9+'L':3+'N':5+'Q':8) = 41
第三段積數位總和 (1+3+0+0+8) = 12
積數位總位 22+41+12= 75 / 11→餘數9
校對碼之第二碼計算
第一段偶數位總和 (9+2+1+0) = 12
第二段偶數位總和 ('B':2+'D':4+'F':6+'H':8+'K':2+'M':4+'P':7+'R':9)= 42
第三段偶數位總和 (2+4+0+0+0+8+0) = 22
偶數位總位 12+42+22= 76 / 11→餘數10
→因此校對碼為 '9Y'
※超商手續費代碼(超商稱之為「代收項目」以台中商銀為例)
機構代碼 | 費用區間 | 手續費 |
625 | 10000以下 | 10 |
62E | 10000-20000 | 15 |
6BE | 20000以上 | 20 |
※超商條碼
條碼一 | 繳費期限(YYMMDD)+機構代碼 | 9碼 |
條碼二 | 16碼 | |
條碼三 | 繳費期限(MMDD)+校對碼(2碼)+繳款金額(9碼) | 15碼 |
