這是一個很好的實現:
// pressableElement: pressable-element
.directive('pressableElement', function ($timeout) {
return {
restrict: 'A',
link: function ($scope, $elm, $attrs) {
$elm.bind('mousedown', function (evt) {
$scope.longPress = true;
$scope.click = true;
// onLongPress: on-long-press
$timeout(function() {
$scope.click = false;
if ($scope.longPress && $attrs.onLongPress) {
$scope.$apply(function() {
$scope.$eval($attrs.onLongPress, { $event: evt });
});
}
}, $attrs.timeOut || 600); // timeOut: time-out
// onTouch: on-touch
if ($attrs.onTouch) {
$scope.$apply(function() {
$scope.$eval($attrs.onTouch, { $event: evt });
});
}
});
$elm.bind('mouseup', function (evt) {
$scope.longPress = false;
// onTouchEnd: on-touch-end
if ($attrs.onTouchEnd) {
$scope.$apply(function() {
$scope.$eval($attrs.onTouchEnd, { $event: evt });
});
}
// onClick: on-click
if ($scope.click && $attrs.onClick) {
$scope.$apply(function() {
$scope.$eval($attrs.onClick, { $event: evt });
});
}
});
}
};
})
用例:
<div pressable-element
ng-repeat="item in list"
on-long-press="itemOnLongPress(item.id)"
on-touch="itemOnTouch(item.id)"
on-touch-end="itemOnTouchEnd(item.id)"
on-click="itemOnClick(item.id)"
time-out="600"
>{{item}}</div>
var app = angular.module('pressableTest', [])
.controller('MyCtrl', function($scope) {
$scope.result = '-';
$scope.list = [
{ id: 1 },
{ id: 2 },
{ id: 3 },
{ id: 4 },
{ id: 5 },
{ id: 6 },
{ id: 7 }
];
$scope.itemOnLongPress = function (id) { $scope.result = 'itemOnLongPress: ' + id; };
$scope.itemOnTouch = function (id) { $scope.result = 'itemOnTouch: ' + id; };
$scope.itemOnTouchEnd = function (id) { $scope.result = 'itemOnTouchEnd: ' + id; };
$scope.itemOnClick = function (id) { $scope.result = 'itemOnClick: ' + id; };
})
.directive('pressableElement', function ($timeout) {
return {
restrict: 'C', // only matches class name
link: function ($scope, $elm, $attrs) {
$elm.bind('mousedown', function (evt) {
$scope.longPress = true;
$scope.click = true;
$scope._pressed = null;
// onLongPress: on-long-press
$scope._pressed = $timeout(function() {
$scope.click = false;
if ($scope.longPress && $attrs.onLongPress) {
$scope.$apply(function() {
$scope.$eval($attrs.onLongPress, { $event: evt });
});
}
}, $attrs.timeOut || 600); // timeOut: time-out
// onTouch: on-touch
if ($attrs.onTouch) {
$scope.$apply(function() {
$scope.$eval($attrs.onTouch, { $event: evt });
});
}
});
$elm.bind('mouseup', function (evt) {
$scope.longPress = false;
$timeout.cancel($scope._pressed);
// onTouchEnd: on-touch-end
if ($attrs.onTouchEnd) {
$scope.$apply(function() {
$scope.$eval($attrs.onTouchEnd, { $event: evt });
});
}
// onClick: on-click
if ($scope.click && $attrs.onClick) {
$scope.$apply(function() {
$scope.$eval($attrs.onClick, { $event: evt });
