首先我們需要一個(gè)html代碼的框架如下：

<div style='position: absolute; top: 0px; left: 168px; width: 100%; margin-left: auto; margin-right: auto; height: 47px; border: 0px solid red; overflow: hidden;'> <ul style='margin: 0px;left:0; top:0;margin-bottom:0px;width:100%;height:47px;position:absolute;'> </ul> </div>

我們的目的是實(shí)現(xiàn)ul中的內(nèi)容進(jìn)行橫向的一點(diǎn)一點(diǎn)滾動(dòng)。ul中的內(nèi)容應(yīng)該是動(dòng)態(tài)的。于是應(yīng)該發(fā)送ajax來進(jìn)行內(nèi)容的獲取拼接。

$.ajax({ type:'post', dataType:'json', url:'${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 class='sstzNoticeStyle'>'+result[i].peopleName+'</a>'+ '</li>'; totalStr +=str; }}$('#syNoticeUlNew').empty();$(’#syNoticeUlNew’).html(totalStr);syRunHorseLight(); } });

拼接li時(shí)候有個(gè)class為sstzNoticeStyle。其樣式如下：

.sstzNoticeStyle{ color:white; font-size:16px;text-decoration:none;}.sstzNoticeStyle:hover{ color:white; font-size:16px;text-decoration:none;}

ajax調(diào)用syRunHorseLight函數(shù)，函數(shù)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); }) } }

跑馬燈效果就此實(shí)現(xiàn)。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
