jquery-mobile - 在 jQuery-mobile 中计算滑动距离

Question

我希望你今天一切都好，我正在尝试计算移动网站上的滑动距离(触摸手势)，你如何计算用户在屏幕上滑动了多少像素？

$('.cmButtons').live('swipeleft',function(){
    console.log("swiped left");
});

Answer 1

不确定这是否有帮助，但在 Beta 2 中，他们发布了一些额外的滑动功能

Configurable swipe event thresholds added

There were a number of hard-coded constants in the jquery.mobile.event.js swipe code. For developers who need to tweak those constants to allow a greater vertical displacement and still register a swipe, this new feature allows them to be adjusted. Thanks to mlitwin for contributing this.

• scrollSupressionThreshold (default: 10px) – More than this horizontal displacement, and we will suppress scrolling
• durationThreshold (default: 1000ms) – More time than this, and it isn’t a swipe
• horizontalDistanceThreshold (default: 30px) – Swipe horizontal displacement must be more than this.
• verticalDistanceThreshold (default: 75px) – Swipe vertical displacement must be less than this.
