JQUERY的TAB标签，我想实现5秒钟自动切换的效果，怎么做
下面这段代码替换你原来的js代码，亲测可用……
原理：
1.设置了一个定时器，每2秒触发。
2.如果用户自己切换，停止定时器。当用户鼠标离开区域时，再次进入定时切换。
不懂再问~
$(function(){
var i=0;//初始记录用户鼠标经过是第几个li
var canmove=true;
$('.menu li').mouseenter(function(){
canmove=false;
clearInterval(li_timer);
i=$(this).index();
$(this).addClass('off').siblings().removeClass('off');
$('.menudiv div').hide();
$('.menudiv div').eq(i).show();
});
$("#tab1").mouseenter(function(){//只要用户鼠标在这个tab1区域内，就不自动跳转
canmove=false;
}).mouseleave(function(){
clearInterval(li_timer);
setTimeout(function(){canmove=true;},2000);//两秒后自动切换
});
function li_timer(){
if(canmove){
i++;
if(i==$('.menu li').length){
i=0;
}
$('.menu li').eq(i).addClass('off').siblings().removeClass('off');
$('.menudiv div').hide();
$('.menudiv div').eq(i).show();
}
}
setInterval(li_timer,2000);//每两秒切换
});
[img]jquery 图片自动切换
需要js+css配合，我给您找段代码吧。
JS代码
$(function () { $(".dummy").click(function () { return false; }); var flipDelay = 5500; var flipCount = $("div.banner_footer a").size(); // 图片总数 var flipId = 1; var flipId1 = 0; var flipTimer = null; var flipTimer1 = null; var i = 0; var flip = function () { if (flipCount 2) return; $("div.banner_footer a").removeClass("current"); $($("div.banner_footer a").get(flipId)).addClass("current"); $($("div.banner_footer a").get(flipId)).css("current"); $("div.banner a:visible").fadeOut(); $($("div.banner a").get(flipId)).fadeIn("slow"); flipId = (flipId + 1) % flipCount; flipTimer = window.setTimeout(flip, flipDelay); } flipTimer = window.setTimeout(flip, flipDelay); $("div.banner_footer a").click(function () { clearTimeout(flipTimer); flipId = $("div.banner_footer a").index(this); flip(); return false; }); var flipserver = function () { $("div.index_server_box a:visible").fadeOut(); $($("div.index_server_box a").get(flipId1)).fadeIn("slow"); } $("a.index_server_left").click(function () { flipId1 = (flipId1 - 1) % 3; flipserver(); return false; }); $("a.index_server_right").click(function () { flipId1 = (flipId1 + 1) % 3; flipserver(); return false; }); var documentWidth = $(window).width(); var left = (documentWidth - 310) / 2; var right = left + 306; $("div.services_box div.left").css("width", left + "px"); $("div.services_box div.right").css("width", right + "px"); $(window).resize(function () { var documentWidth = $(window).width(); var left = (documentWidth - 310) / 2; var right = left + 306; $("div.services_box div.left").css("width", left + "px"); $("div.services_box div.right").css("width", right + "px"); });});

jquery选项卡自动切换时间怎么调
timer=setTimeout("start_autochange()",1000);
第二个参数表示延迟执行的时间，单位为毫秒，1000表示为延迟1秒执行
