使用官方文档的代码,window.flag1 = true;var self1 = this;//鼠标悬停,滚动停止setTimeout(function() { $("div").find(".frozen-center").mouseover(function() { window.flag1 = false; }); //鼠标离开,继续滚动 $("div").find(".frozen-center").mouseleave(function() { window.flag1 = true; }); var old = -1; var interval = setInterval(function() { if (!self1.isVisible()) { return; } if (window.flag1) { currentpos1 = $("div").find(".frozen-center").scrollTop; if (currentpos1 == old && 0!=currentpos1) { $("div").find(".frozen-center").scrollTop = 0; } else { old = currentpos1; //以25ms的速度每次滚动1.5PX $("div").find(".frozen-center").scrollTop = currentpos1 + 1.5; } } }, 25); }, 1000);
