我是Angular的新手,我正在尝试使用angular-hammer.js指令获取水龙头的XY坐标。以下是指令的设置方式:
var hmTouchevents = angular.module('hmTouchevents', []),
hmGestures = ['hmHold:hold',
'hmTap:tap',
'hmDoubletap:doubletap',
'hmDrag:drag',
'hmDragup:dragup',
'hmDragdown:dragdown',
'hmDragleft:dragleft',
'hmDragright:dragright',
'hmSwipe:swipe',
'hmSwipeup:swipeup',
'hmSwipedown:swipedown',
'hmSwipeleft:swipeleft',
'hmSwiperight:swiperight',
'hmTransform:transform',
'hmRotate:rotate',
'hmPinch:pinch',
'hmPinchin:pinchin',
'hmPinchout:pinchout',
'hmTouch:touch',
'hmRelease:release'];
angular.forEach(hmGestures, function(name){
var directive = name.split(':'),
directiveName = directive[0],
eventName = directive[1];
hmTouchevents.directive(directiveName, ["$parse", function($parse) {
return {
scope: true,
link: function(scope, element, attr) {
var fn, opts;
fn = $parse(attr[directiveName]);
opts = $parse(attr["hmOptions"])(scope, {});
scope.hammer = scope.hammer || Hammer(element[0], opts);
return scope.hammer.on(eventName, function(event) {
return scope.$apply(function() {
return fn(scope, {
$event: event
});
});
});
}
};
}
]);
});
我的HTML看起来像这样:
<div ng-controller="IndexCtrl" >
<div class='tap-area' hm-tap="tap();">
</div>
</div>
我的控制器看起来像这样:
App.controller('IndexCtrl', function ($scope, Myapp) {
$scope.tap = function(ev){
//How do I get the event.gesture.center.pageX in here?
};
});

我想出了如何使这项工作。在return scope.hammer.on(eventName, function(event) {
之后我添加了scope.event = event;
,然后在我的控制器中,我可以使用this.event.center.pageX
或this.event.center.pageY
获得点按的XY坐标。

它是很久以前发布的,但这是另一个解决方案。
只需将$ event添加到您的html
