Javascript - 图像不循环/旋转

Question

我正在编写一个脚本，用于在 javascript 中旋转/循环浏览图像，同时遵守循环浏览图像的次数限制。我所拥有的如下:

<a id="imageurl"><img id="Rotating1" border="0"></img></a>

<script language="JavaScript">

var delay = 3000; //6000 = change to next image after 6 seconds
var cycles = 2;
var currentCycle = 0;

function RotateImages(Start, delay)
{
    var a = new Array("frown.gif","grim.gif","smile.gif", "bomb.gif");
    var c = new Array("url1", "url2", "url3", "url4");
    var b = document.getElementById('Rotating1');
    var d = document.getElementById('imageurl');
    var totalCycles = cycles * a.length;
//  alert ("currentCycle: " + currentCycle);
//  alert ("totalCycles: " + totalCycles);

        if (Start>=a.length) 
            Start=0;
        b.src = a[Start];
        d.href = c[Start];

        if (currentCycle < totalCycles) {
            window.setTimeout("RotateImages(" + (Start+1) + ")", delay);
            currentCycle++;
        }
}

RotateImages(0, delay);

</script>

当我取消注释警报框时，脚本的行为就像它正在工作一样。当我注释掉它们时，旋转似乎停止了。关于到底发生了什么以及如何解决它有什么想法吗？

谢谢!

Answer 1

也许您想更改此行:

window.setTimeout("RotateImages(" + (Start+1) + ")", delay);

进入:

window.setTimeout("RotateImages(" + (Start+1) + ", " + delay + ")", delay);

这样下次调用RotateImages时，它将保持延迟。
