请注意,如果您出于某种原因不使用 jQuery Mobile,则此解决方案很有用。我使用了文章快速触摸事件处理并添加了一段代码
$.event.special.tap = {
distanceThreshold: 10,
timeThreshold: 350,
setup: function () {
var self = this,
$self = $(self);
// Bind touch start
$self.on('touchstart', function (startEvent) {
// Save the target element of the start event
var target = startEvent.target,
touchStart = startEvent.originalEvent.touches[0],
startX = touchStart.pageX,
startY = touchStart.pageY,
threshold = $.event.special.tap.distanceThreshold,
timeout,
expired = false;
function timerFired() {
expired = true;
}
function removeTapHandler() {
clearTimeout(timeout);
$self.off('touchmove', moveHandler).off('touchend', tapHandler).off('touchcancel', removeTapHandler);
};
function tapHandler(endEvent) {
removeTapHandler();
if (target == endEvent.target) {
if (expired) {
$.event.simulate('longtap', self, endEvent);
} else {
$.event.simulate('tap', self, endEvent);
}
}
};
// Remove tap and move handlers if the touch moves too far
function moveHandler(moveEvent) {
var touchMove = moveEvent.originalEvent.touches[0],
moveX = touchMove.pageX,
moveY = touchMove.pageY;
if (Math.abs(moveX - startX) > threshold || Math.abs(moveY - startY) > threshold) {
removeTapHandler();
}
};
// Remove the tap and move handlers if the timeout expires
timeout = setTimeout(timerFired, $.event.special.tap.timeThreshold);
// When a touch starts, bind a touch end and touch move handler
$self.on('touchmove', moveHandler).on('touchend', tapHandler).on('touchcancel', removeTapHandler);
});
}
};
所以,现在我有一个 tap 和一个 longtap 事件
