這是我從觸摸事件中獲得的返回數據。顯着缺失的是任何有用的觸摸X/Y座標(https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent/changedTouches)。這是一個毫無希望的通用問題,但是,還有什麼想法? 「事件」對象傳遞給觸摸執行的功能:Touch in Angular
{
"originalEvent": {
"isTrusted": true
},
"type": "touchstart",
"timeStamp": 1450388006795,
"jQuery203026962137850932777": true,
"which": 0,
"view": "$WINDOW",
"target": {},
"shiftKey": false,
"metaKey": false,
"eventPhase": 3,
"currentTarget": {},
"ctrlKey": false,
"cancelable": true,
"bubbles": true,
"altKey": false,
"delegateTarget": {},
"handleObj": {
"type": "touchstart",
"origType": "touchstart",
"data": null,
"guid": 2026,
"namespace": ""
},
"data": null
}
現在,這是在畫布的角度UI模式,但鼠標事件做工精細。這裏是我的元素BTW:
link: function(scope, element, attrs, model){
//scope.canvasElem = element[0].children[0].children[0];
scope.canvasElem = angular.element($('.touchScreen'))[0];
scope.ctx = scope.canvasElem.getContext('2d');
下面是我如何綁定一個例子:
element.bind('touchstart', scope.touchStart);
編輯,這裏是比較mouseDown事件對象:
{
"originalEvent": {
"isTrusted": true
},
"type": "mousedown",
"timeStamp": 1450389131400,
"jQuery20309114612976554781": true,
"toElement": {},
"screenY": 436,
"screenX": 726,
"pageY": 375,
"pageX": 726,
"offsetY": 81,
"offsetX": 41,
"clientY": 375,
"clientX": 726,
"buttons": 1,
"button": 0,
"which": 1,
"view": "$WINDOW",
"target": {},
"shiftKey": false,
"relatedTarget": null,
"metaKey": false,
"eventPhase": 3,
"currentTarget": {},
"ctrlKey": false,
"cancelable": true,
"bubbles": true,
"altKey": false,
"delegateTarget": {},
"handleObj": {
"type": "mousedown",
"origType": "mousedown",
"data": null,
"guid": 2025,
"namespace": ""
},
"data": null
}
嘿,我很欣賞的答覆,你可以在我如何獲得該包裝,請詳細點嗎? – VSO
@VSO我添加了一個如何將原始事件對象記錄到控制檯的示例。 –
我試過了,它返回的結果是:{「isTrusted」:true}。原始對象中的屬性(在我的問題文章中)就是我可以訪問的所有內容。我真的很希望我失去了一些東西。 – VSO
