// 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]); };
//

我有这个问题，这是一个奇怪的错误。如果您有超过3个图像（4个或更多图像），那么所发生的是不是淡入下一个图像，而是淡入下一个到最后一个图像。如果你只有三个图像，它工作正常。但我需要6张图片。
例如，如果我有6张图片，那么：
图像＃1出现，
然后图像＃1淡入图像＃5，然后出现图像＃2，
然后图像＃2淡入图像＃5，然后出现图像＃3，
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，然后出现图像＃6，
然后图像＃6淡入图像＃1然后图像＃1出现
如你所见，当它到达倒数第二个图像时，它开始正常工作。但是如果你重新加载页面，这个奇怪的bug就会重新开始循环。
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
你能否告诉我如何解决这个问题，以确保幻灯片可以正常显示超过3张图像？
注意： 图片太大不是问题。如果它是1px x 1px图像，也会发生同样的事情。
（注意：演示图像不再存在）
好的，所以我正在取得进展 -
看起来显示的是SECOND TO LAST的原因，因为显然所有图像都显示在一个重复的框中;只是，它们随着数量的增加而消失。除了最后一个图像之外，所有不透明度都被赋予1，最后一个图像被赋予不透明度-0.001，这使得它被隐藏，因此为什么你会看到倒数第二个而不是最后一个。
但应该发生的是ALL，但是第一个应该被赋予不透明度-0.001，直到它们的数量出现。 （当他们的号码出现时，由于某种原因，他们的副本会消失，并且javascript会手动覆盖具有不透明度的HTML元素的页面CSS。）
解决!!!! YAY !!!!
好的，所以你需要添加以下CSS：
#bg img {
opacity: -0.001;
}
只是一个注释，你需要用！important强制图像位置。例如，div id为bg的完整CSS是：
#bg {
position: absolute;
z-Index:0;
}
#bg img {
position: absolute;
top: 50px !important;
left: 50px !important;
opacity: -0.001;
}
答案 0 :(得分：0)
