是这种   就是不能滑到一半

然后想到了这种方法  只能凑合用了

scrollEnd:function(e){

    var _this = this;

    var str = “listOver[” + e.currentTarget.dataset.datas + “].scrollLeft”;

    setTimeout(function(){

        const query = wx.createSelectorQuery()

        query.select(’.orderListOver’ + e.currentTarget.dataset.datas).boundingClientRect()

        query.exec(function (res) {

            var left = res[0].left;

            _this.setData({

            [str]: left<-30?100:0

        })

    })

    },100)

},
