Question

我创建了一个使用HTML和CSS的幻灯片，但需要让它自动播放并像暂停选项一样添加控件。

这是我的代码。

您必须制作JavaScript文件或将此部分添加到HTML文件的末尾。这是一个简单的样本：

<script language="JavaScript">
var i = 0;
var path = new Array();

// LIST OF IMAGES
path[0] = "image_1.gif";
path[1] = "image_2.gif";
path[2] = "image_3.gif";

function swapImage()
{
   document.slide.src = path[i];
   if(i < path.length - 1) i++; else i = 0;
   setTimeout("swapImage()",3000);
}
window.onload=swapImage;
</script>

在HTML文件中，每个IMG标记都应该有一个src和name属性，如下所示：

<img height="200" name="slide" src="image_1.gif" width="400" />

尝试在Google中搜索。有很多样本。来源：http://www.siteforinfotech.com/2013/07/create-simple-image-slideshow-using-javascript.html
