About jquery using scroll to implement pull-up and pull-down loading and refreshing

This article mainly introduces in detail how jquery uses iscorll to implement pull-up and pull-down loading and refreshing. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

The implementation principle is: judge whether fiiptop and flipdown are displayed as the basis

##

myScroll = new iScroll('wraphome', { 
        fixedScrollbar: true, 
        hideScrollbar: true, 
        fadeScrollbar: true, 
        hScrollbar: false, 
        vScrollbar: true, 
        onScrollMove: function () { 
          var topstat = $(".fliptop").is(":visible"); 
          var downstat = $(".flipdown").is(":visible"); 
          if (this.y > 15 && !topstat && !downstat) { 
            $(".fliptop").fadeIn(300); 
          } else if (this.y < 15 && topstat) { 
            $(".fliptop").hide(); 
          } else if (this.y < (this.maxScrollY - 25) && !topstat && !downstat) { 
            $(".flipdown").fadeIn(300); 
            this.refresh(); //这里是当显示正在加载中时刷新底部位置 
          } else if (this.y > (this.maxScrollY + 25) && downstat) { 
            $(".flipdown").hide(); 
          } 
        }, 
        onTouchEnd: function () { 
          var topstat = $(".fliptop").is(":visible"); 
          var downstat = $(".flipdown").is(":visible"); 
          if (topstat && !downstat) { 
            $(".fliptop").html("正在加载中……"); 
            setTimeout(function(){ 
              //此处为你自己的逻辑方法 
            },3000); 
          } else if (downstat && !topstat) { 
            $(".flipdown").html("正在加载中……"); 
            setTimeout(function(){ 
              //此处为你自己的逻辑方法 
            },3000); 
          } 
 
        } 
      });
