firefox下rowspan+border+border-collapse的bug
652
2024-03-30
自己寫了一個純jq形式的橫向輪播焦點圖，可點擊小圓點或者左右按鈕進行切換，屬于定寬類型。改成自適應寬度的也不難，將css里面的bannerCon寬度改為百分比，再在js里面將ul和li的寬度跟隨父級容器的寬度變化即可，需要用到$(window).resize。
兼容到IE6+以上瀏覽器，有輪播速度和切換間隔兩個參數可以改。
效果圖如下：
Html代碼如下：
<html> <head> <meta charset="utf-8"> <title>banner圖</title> <link rel="stylesheet"/> <script src="http://www.gimoo.net/t/1903/js/jquery-1.9.1.min.js"></script> <script src="http://www.gimoo.net/t/1903/js/common.js"></script> </head> <body> <div class="wrap"> <div class="banner"> <div class="bannerCon"> <ul class="imgList"> <li><a ><img src="http://www.gimoo.net/t/1903/images/banner01.jpg" alt=""/></a></li> <li><a ><img src="http://www.gimoo.net/t/1903/images/banner02.jpg" alt=""/></a></li> <li><a ><img src="http://www.gimoo.net/t/1903/images/banner03.jpg" alt=""/></a></li> </ul> <ul class="btnList clearfix"> <li class="cur"><span></span></li> <li><span></span></li> <li><span></span></li> </ul> <span class="pre-nex prev"><</span> <span class="pre-nex next">></span> </div> </div> </div> </body> </html>
Css樣式如下：
@charset "utf-8";
/* 簡單reset */
body, p, ul, ol, li {
margin: 0;
padding: 0;
}
ul, ol {
list-style: none;
}
img { border:none; }
a,button{ outline: none; }
.clearfix:after {
visibility: hidden;
display: block;
font-size: 0;
content: " ";
clear: both;
height: 0;
}
/* 具體樣式 */
.banner {
position: relative;
height: 400px;
overflow: hidden;
}
.banner .bannerCon {
position: absolute;
top: 0;
left: 50%;
width: 800px;
height: 400px;
margin-left: -400px;
overflow: hidden;
}
.bannerCon .imgList {
position: absolute;
top: 0;
left: 0;
width: 99999px;
height: 400px;
}
.bannerCon .imgList li {
float: left;
width: 800px;
height: 400px;
}
.bannerCon .imgList li a {
position: relative;
display: block;
height: 100%;
}
.bannerCon .imgList li img {
width: 800px;
height: 400px;
}
.bannerCon .pre-nex {
display: none;
position: absolute;
top: 50%;
width: 40px;
height: 60px;
margin-top: -40px;
font: bold 40px/60px Simsun;
color: #ccc;
text-align: center;
border:none;
background: rgba(0,0,0,.30);
filter:progid:DXImageTransform.Microsoft.Gradient(startColorStr=#4c000000, endColorStr=#4c000000);
cursor: pointer;
z-index: 3;
}
.bannerCon .pre-nex.show { display: inline-block; }
.bannerCon .prev { left: 13%; }
.bannerCon .next { right: 13%; }
.bannerCon .btnList {
position: absolute;
left: 0;
bottom: 20px;
width: 100%;
height: 12px;
text-align:center;
z-index: 2;
_overflow: hidden;
}
.bannerCon .btnList li { display: inline; }
.bannerCon .btnList li span {
display: inline-block;
width: 12px;
height: 12px;
margin: 0 5px;
border-radius: 6px;
background-color:#14829e;
cursor: pointer;
}
.bannerCon .btnList li.cur span { background-color: #f30; }
Js代碼如下：
//加載在文本讀取之后的js語句 開始 =============================================================
function Scroll(obj,speed,interval){ //父級容器，輪播速度，切換間隔
$("."+obj).each(function(){
var $box = $(this),
$imgUl = $box.children(".imgList"),
$imgLi = $imgUl.children("li"),
$btnUl = $box.children(".btnList"),
$btnLi = $btnUl.children("li"),
$btnPreNex = $box.children(".pre-nex"),
$btnPre = $box.children(".prev"),
$btnNex = $box.children(".next"),
n = $imgLi.length,
width = $imgLi.width(),
left = parseFloat($imgUl.css("left")),
k = 0,
Player;
$imgUl.css("width",n*width);
function scroll(){ //輪播事件
$imgUl.stop().animate({left:-width},speed,function(){
k += 1;
$imgUl.css("left",0);
$imgUl.children("li:first").appendTo($(this));
$btnLi.removeClass('cur');
if(k >= n){
k = 0;
}
$btnUl.children("li").eq(k).addClass('cur');
});
}
$btnLi.click(function(){ //小圓點點擊事件
var index = $btnLi.index(this);
$(this).addClass('cur').siblings("li").removeClass('cur');
if(index >= k){
var dif = index-k;
left = -dif*width;
$imgUl.stop().animate({left:left},speed,function(){
$imgUl.css("left",0);
$imgUl.children("li:lt("+dif+")").appendTo($imgUl);
});
}
else{
var j = n-(k-index);
$imgUl.css("left",(index-k)*width);
$imgUl.children("li:lt("+j+")").appendTo($imgUl);
$imgUl.stop().animate({left:0},speed);
}
k = index;
});
$btnPreNex.click(function(){ //左右按鈕點擊事件
var index = $btnLi.index(this);
if($(this).hasClass('next')){
if(!$imgUl.is(":animated")){
k += 1;
$imgUl.animate({left:-width},speed,function(){
$imgUl.css("left",0);
$imgUl.children("li:first").appendTo($(this));
if(k >= n){
k = 0;
}
$btnUl.children("li").removeClass('cur').eq(k).addClass('cur');
});
}
}
else {
if(!$imgUl.is(":animated")){
k += -1;
$imgUl.css("left",-width);
$imgUl.children("li:last").prependTo($imgUl);
$imgUl.stop().animate({left:0},speed);
if(k < 0){
k = n-1;
}
$btnUl.children("li").removeClass('cur').eq(k).addClass('cur');
}
}
});
$box.hover( //鼠標移入、移出事件
function(){
clearInterval(Player);
$btnPreNex.addClass('show');
},
function(){
Player = setInterval(function(){scroll()},interval);
$btnPreNex.removeClass('show');
}
);
Player = setInterval(function(){scroll()},interval);
});
}
$(function () { //讀取輪播事件
Scroll("bannerCon",600,4000);
});
注意加載一下jq庫，我用的是1.9.1的，其實1.7+的都沒問題的。
