#content6 { float: left; background: url(img/主页图片/adv_01.jpg); width: 533px; height: 280px; } /*.span3 li{clear: both;}*/ .content6-1 { width: 533px; height: 40px; background: #353535; position: relative; top: 240px; /*left: -20px;*/ }
静态网页效果图
jQuery实现
实现定时器效果
function a() { //alert(j); if(j > 4) { j = 0; } // alert(j); $("#content6").css("background","url(img/主页图片/adv_0" + (j+1) + ".jpg)");//轮播广告,替换当前广告 t = setTimeout(a, 1000);//定时器 $(".content6-1 ul li").each(function(i,e){ //遍历每一个并获取下标 if(i==j) { $(e).css("background","#D52D02");//改变当前选中项的背景颜色 } else { $(e).css("background","#353535"); } }) j++; } a();//在开始加载时调用代码
实现悬浮效果
$(".content6-1 ul li").mouseenter(function(){ j=$(this).index(); $("#content6").css("background","url(img/主页图片/adv_0" + (j+1)+ ".jpg)"); $(this).css("background","#D52D02") .siblings().css("background","#353535"); clearTimeout(t);//定时器停止在当前选中的项 // alert(j); })
实现移开效果
$(".content6-1 ul li").mouseleave(function(){ j++; setTimeout(a, 1000); })
JS脚本实现
实现定时器效果
var menus = document.querySelectorAll(".content6-1 ul li"); function a() { j++; if(j > 5) { j = 1; } // alert(i); // $("#content6").css({ "background": "url(img/主页图片/adv_0" + j + ".jpg)" }); document.querySelector("#content6").style.background = "url(img/主页图片/adv_0" + j + ".jpg)"; for(var i = 0; i < menus.length; i++) { menus[i].onmouseenter = enter; menus[i].onmouseleave = leave; } for(var i = 0; i < menus.length; i++) { if(i + 1 == j) { menus[i].style.background = "#D52D02"; } else { menus[i].style.background = "#353535"; } } t = setTimeout(a, 1000); } a();
悬浮效果
function enter() { for(var i = 0; i < menus.length; i++) { if(this == menus[i]) { j = i + 1; menus[i].style.background = '#D52D02'; document.querySelector("#content6").style.background = "url(img/主页图片/adv_0" + j + ".jpg)"; } else { menus[i].style.background = '#353535'; } } clearTimeout(t); }
移开效果
function leave() { j--; a(); }
