简单的实现点击箭头图片切换的js代码
步骤如下:
(1) 准备图片(左右箭头,以及一些示例图片)
<script type="text/javascript" src="JS/jquery-1.4.4.js"></script>
<script type="text/javascript">
var picPath = new Array();
picPath.push("Images/chuang_yhb.jpg");
picPath.push("Images/dong_wgx.jpg");
picPath.push("Images/gao_xsg.jpg");
var index = 0;
$(function() {
var top = $("#img1").offset().top;
var left = $("#img1").offset().left;
var height = $("#img1").height();
var width = $("#img1").width();
$("#img1").attr({ "src": picPath[index] });
$("#img1").parent().hover(function() {
//show the arrow left and right
$("#leftArrow").show();
$("#rightArrow").show();
$("#leftArrow").css({ "left": left - 10, "top": top + (height / 2) });
$("#rightArrow").css({ "left": left + width, "top": top + (height / 2) });
}, function() {
//hide the arrrow left and right
$("#leftArrow").hide();
$("#rightArrow").hide();
});
$("#leftArrow").click(function() {
if (index > 0) {
$("#img1").attr({ "src": picPath[--index] });
}
});
$("#rightArrow").click(function() {
if (index < picPath.length) {
$("#img1").attr({ "src": picPath[++index] });
}
});
});
</script>
<div>
<img id="img1" alt="Show Pictures" style="margin-left:100px;" />
<img id="leftArrow" alt="Left Arrow" src="Images/arrowa.jpg" style="position:absolute;display:none;width:50px;height:35px;z-index:99" />
<img id="rightArrow" alt="Right Arrow" src="Images/arrowb.jpg" style="position:absolute;display:none;width:50px;height:35px;z-index:99" />
</div>
下面再附一个js版的
无标题文档
$=function(obj){return document.getElementById(obj);}
//图片地址
var imgsrc= new Array();
imgsrc[0]="http://img1.gtimg.com/0/68/6884/688412_550x550_0.jpg";
imgsrc[1]="http://img1.gtimg.com/0/68/6899/689943_550x550_0.jpg";

imgsrc[7]="http://img07.taobaocdn.com/tps/i7/T15wlEXmlEXXXXXXXX-638-369.jpg";
imgsrc[8]="http://img01.taobaocdn.com/tps/i1/T1tjxEXclXXXXXXXXX-638-369.jpg";
//图片预加载
var arr = new Array();
for(var i=1; i=imgsrc.length){i=0}
$("showimg").setAttribute("src",imgsrc[i]);
$("intro").innerHTML=title[i]
}
$("pre").onclick=function (){
i--;
if(i
