如何将下一个和上一个按钮添加到图像galary

How to add next and previous buttons to image galary

本文关键字：添加 图像 galary 按钮 上一个 下一个      更新时间：2023-09-26

我知道有人问我这个问题，我在这里搜索了又搜索，但a）我似乎不知道如何调整我的发现，b）我还有另一个小问题要处理，试图将下一个和上一个按钮添加到我的图库布局中。

这是我的页面链接：

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

第二个问题是，我对我的图像使用了纯css渐变效果，但我找不到在页面加载时显示库的第一个图像的方法。

正如你所看到的，我已经有了下一个/上一个链接。只是对js/jquery了解不够，无法使其正常工作。

任何帮助都将不胜感激

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>

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;
}

我已经用jQuery用上一个和下一个按钮为图像幻灯片制作了完整的bin。我认为这个演示应该对你有帮助，所以下面的演示链接。
