// Animate (11-January-2010)
// by Vic Phillips http://www.vicsjavascripts.org.uk
// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With the ability to scale the effect time on specified minimum/maximum values
// and with three types of progression 'sin' and 'cos' and liner.
// **** Application Notes
// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'
//
// The element would normally be assigned a unique ID name.
//
// **** Initialising the Script.
//
// The script is initialised by assigning an instance of the script to a variable.
// e.g A = new zxcAnimate('left','id1')
// where:
// A = a global variable (variable)
// parameter 0 = the mode(see Note 1). (string)
// parameter 1 = the unique ID name or element object. (string or element object)
// parameter 1 = the initial value. (digits, default = 0)
// **** Executing the Effect
//
// The effect is executed by an event call to function 'A.animate(10,800 ,5000,[10,800]);'
// where:
// A = the global referencing the script instance. (variable)
// parameter 0 = the start value. (digits, for opacity minimum 0, maximum 100)
// parameter 1 = the finish value. (digits, for opacity minimum 0, maximum 100)
// parameter 2 = period of time between the start and finish of the effect in milliseconds. (digits or defaults to previous or 0(on first call) milliSeconds)
// parameter 3 = (optional) to scale the effect time on a specified minimum/maximum. (array, see Note 3)
// field 0 the minimum value. (digits)
// field 1 the maximum value. (digits)
// parameter 3 = (optional) the type of progression, 'sin', 'cos' or 'liner'. (string, default = 'liner')
// 'sin' progression starts fast and ends slow.
// 'cos' progression starts slow and ends fast.
//
// Note 1: Examples modes: 'left', 'top', 'width', 'height', 'opacity.
// Note 2: The default units(excepting opacity) are 'px'.
// For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
// Note 3: The scale is of particular use when re-calling the effect
// in mid progression to retain an constant rate of progression.
// Note 4: The current effect value is recorded in A.data[0].
// Note 5: A function may be called on completion of the effect by assigning the function
// to the animator intance property .Complete.
// e.g. [instance].Complete=function(){ alert(this.data[0]); };
//

我有一个问题，这是一个奇怪的错误。如果您有超过 3 张图像（4 张或更多图像），那么会发生的不是淡入下一张图像，而是淡入倒数第二张图像。如果您只有三个图像，它工作正常。但我需要 6 张图片。
例如，如果我有 6 张图像，那么：
图像#1 出现，
然后图像#1 淡入图像#5，然后图像#2 出现，
然后图像#2 淡入图像#5，然后图像#3 出现，
然后图像#3 淡入图像#5，然后出现图像#4，
然后图像#4 淡入图像#5，然后出现图像#5，
然后图像#5 淡入图像#6，然后图像#6 出现，
然后图像#6淡入图像#1，然后出现图像#1
如您所见，当它到达倒数第二张图像时，它开始正常工作。但是，如果您重新加载页面，则循环会以这个奇怪的错误重新开始。
但应该发生的是：
图像#1 出现，
然后图像#1 淡入图像#2，
然后图像#2 淡入图像#3，
然后图像#3 淡入图像#4，
然后图像#4 淡入图像# 5，
然后图像#5淡入图像#6，
然后图像#6淡入图像#1
你能告诉我如何解决这个问题，以便淡入淡出在 3 张以上的图像上正常工作吗？
注意： 图像太大不是问题。如果它是 1px x 1px 图像，也会发生同样的事情。
（注：演示图像不再存在）
好的，所以我正在取得进展——
显示 SECOND TO LAST 的原因似乎是因为显然所有图像都显示在重复框中；只是，随着数量的增加，它们就会消失。除了最后一个图像之外，所有图像的不透明度都为 1，最后一个图像的不透明度为 -0.001，这使其隐藏，因此您看到倒数第二个而不是最后一个。
但是应该发生的是所有，但第一个应该被赋予不透明度-0.001，直到他们的数字出现。（当他们的号码出现时，由于某种原因，他们的副本消失了，并且 javascript 手动覆盖了具有不透明度的 HTML 元素的页面 CSS。）
解决了！！！！耶！！！！
好的，所以您需要添加以下 CSS：
#bg img {
opacity: -0.001;
}
请注意，您需要使用 !important 强制图像位置。例如，bg 的 div id 的完整 CSS 是：
#bg {
position: absolute;
z-Index:0;
}
#bg img {
position: absolute;
top: 50px !important;
left: 50px !important;
opacity: -0.001;
}
