首先我们需要一个html代码的框架如下：
<div> <ul> </ul> </div>
我们的目的是实现ul中的内容进行横向的一点一点滚动。ul中的内容应该是动态的。于是应该发送ajax来进行内容的获取拼接。
$.ajax({ type:"post", dataType:"json", url:"${contextPath}/indexPage/getSyNoticeInfo", success:function(result){ var totalStr = ""; if(result.length>0){ for(var i=0 ; i<result.length;i++){ str = "<li style=\"list-style: none;display:inline-block;float:left;height:47px;padding-right:50px;line-height:47px;\">"+ "<a style=\"color:white;\" class=\"sstzNoticeStyle\">"+result[i].peopleName+"</a>"+ "</li>"; totalStr +=str; } } $("#syNoticeUlNew").empty(); $('#syNoticeUlNew').html(totalStr); syRunHorseLight(); } });
拼接li时候有个class为sstzNoticeStyle。其样式如下：
.sstzNoticeStyle{ color:white; font-size:16px;text-decoration:none; } .sstzNoticeStyle:hover{ color:white; font-size:16px;text-decoration:none; }
ajax调用syRunHorseLight函数，函数如下：
function syRunHorseLight() { if (syTimer != null) { clearInterval(syTimer); } var oUl = document.getElementById("syNoticeUlNew"); if(oUl != null){ oUl.innerHTML += oUl.innerHTML; oUl.innerHTML += oUl.innerHTML; oUl.innerHTML += oUl.innerHTML; var lis = oUl.getElementsByTagName('li'); var lisTotalWidth = 0; var resetWidth = 0; for (var i = 0; i < lis.length; i++) { lisTotalWidth += lis[i].offsetWidth; } for (var i = 1; i <= lis.length / 4; i++) { resetWidth += lis[i].offsetWidth; } oUl.style.width = lisTotalWidth + 'px'; var left = 0; syTimer = setInterval(function() { left -= 1; if (left <= -resetWidth) { left = 0; } oUl.style.left = left + 'px'; }, 20) $("#syNoticeUlNew").hover(function() { clearInterval(syTimer); }, function() { clearInterval(syTimer); syTimer = setInterval(function() { left -= 1; if (left <= -resetWidth) { left = 0; } oUl.style.left = left + 'px'; }, 20); }) } }
跑马灯效果就此实现。
