如何将下一个和上一个按钮添加到图库

时间:2012-08-03 04:20:20

标签: javascript jquery css

我知道这个问题已被问及我在这里搜索和搜索但a)我似乎无法弄清楚如何调整我发现的东西和b)我还有另外一个小问题尝试将下一个和上一个按钮添加到我的gallery-ish布局。

以下是我页面的链接:

http://mymediaculture.com/_broadway_branding/index2.html

第二个问题是我正在使用纯css fadein / out过渡效果,对于我的图像,但是当页面加载时我无法找到一种方法来显示图库的第一个图像。

如您所见,我已经有了下一个/上一个链接。只是对js / jquery不够了解才能使它们发挥作用。

非常感谢任何帮助

HTML

 <div id="top_mid_mid">
    <a rel="nofollow" target="_blank" href="#">
        <img id="mypicture" border="0" alt="portfolio" src="images/recent/recent1.jpg" />
    </a>
    <div id="prev"><a class="current" href="#"  title="portfolio"><img  alt="prev" src="images/prev.gif" id="prevlink" /></a></div>
        <div id="next"><a class="current" href="#"   title="portfolio"><img  alt="next" src="images/next.gif" id="nextlink" /></a></div>

</div>

的javascript

window.onload= recent_pic;
window.onload= toogle;

var mypix=new Array("images/recent/recent1.jpg","images/recent/recent2.jpg","images/recent/recent3.jpg","images/recent/recent4.jpg","images/recent/recent5.jpg");

var thispic = 0;

function recent_pic(){
    document.getElementById("prevlink").onclick=processprev;
    document.getElementById("nextlink").onclick=processnext;

        document.getElementById(1).onclick =  one;
        document.getElementById(2).onclick =  tow;
        document.getElementById(3).onclick =  three;
        document.getElementById(4).onclick =  four;
        document.getElementById(5).onclick =  five;

}

/******************for arrow ****************/
function processprev(){
    if(thispic==0){
        thispic=mypix.length;
    }
    thispic--;
    document.getElementById("mypicture").src= mypix[thispic];
    return false;
}

function processnext(){
    thispic++;
    if(thispic==mypix.length){
        thispic=0;
    }
    document.getElementById("mypicture").src= mypix[thispic];
    return false;
}

我使用jQuery为使用上一个和下一个按钮的图像幻灯片放映完成了完整的垃圾箱。我认为这个演示应该对你有所帮助,所以演示链接如下。
