[微信小程序]bindtap获取的force字段含义 [换个简单的问我吧!]

对一个按钮设置bindtap的事件,采集到的数据中,有一项是force,如下所示:

{"type":"tap","timeStamp":7667,"target":{"id":"","offsetLeft":0,"offsetTop":0,"dataset":{}},"currentTarget":{"id":"","offsetLeft":0,"offsetTop":0,"dataset":{}},"detail":{"x":276.4107360839844,"y":22.62050437927246},"touches":[{"identifier":0,"pageX":276.4107360839844,"pageY":22.62050437927246,"clientX":276.4107360839844,"clientY":22.62050437927246,"force":1}],"changedTouches":[{"identifier":0,"pageX":276.4107360839844,"pageY":22.62050437927246,"clientX":276.4107360839844,"clientY":22.62050437927246,"force":1}],"_requireActive":true,"_relatedInfo":{"anchorTargetText":"一键复制","anchorRelatedText":"","anchorTapTime":1549955498761}}


其中"force":1这个字段是什么含义? 官网文档并无解释。特此求助。

  • force表示压力大小,是从0.0(没有压力)到1.0(最大压力)的浮点数 , 这几个字都认识,放在一起就不理解了。
  • 不懂+1, 不懂就算了懂了会伤的
  • 3D touch?, 看的我一脸懵,都开始怀疑我的智商了。
