微信小程序頁面滾動到指定位置

假設頁面上有位置#content，代碼如下

var query = wx.createSelectorQuery();
query.selectViewport().scrollOffset();
query.select("#content").boundingClientRect();
query.exec(function (res) {
   console.log(res);
   var miss = res[0].scrollTop + res[1].top - 100;
   wx.pageScrollTo({
      scrollTop: miss,
      duration: 300
   });
});
