我即将举行的婚礼的网站 (www.hilaryandmatthew.com) 有一个非常漂亮的 JQuery 幻灯片（由 www.dynamicdrive.com 提供）
我希望我能尽快得到一些帮助，我真的希望我的网站在发出邀请之前看起来很清晰。我对jQuery一无所知。因此，我遇到了复制粘贴开源代码的陷阱。
当我尝试在 IE8 中加载页面时出现此错误：
消息：'imagearray[...].0' 为空或不是对象行：39 字符：3 代码：0 URI：http ://www.hilaryandmatthew.com/includes/slideshow/fadeslideshow.js
这是我的图像数组的代码，它传递到函数'fadeSlideShow(settingarg)'
<script type="text/javascript">
var mygallery=new fadeSlideShow({
wrapperid: "fadeshow1", //ID of blank DIV on page to house Slideshow
dimensions: [267, 200], //width/height of gallery in pixels. Should reflect dimensions of largest image
imagearray: [
["images/ss1.jpg", "", "", ""],
["images/ss2.jpg", "", "", ""],
["images/ss3.jpg", "", "", ""],
["images/ss4.jpg", "", "", ""],
["images/ss5.jpg", "", "", ""],
["images/ss6.jpg", "", "", ""],
["images/ss7.jpg", "", "", ""],

],
displaymode: {type:'auto', pause:2800, cycles:0, wraparound:false},
persist: false, //remember last viewed slide and recall within same session?
fadeduration: 600, //transition duration (milliseconds)
descreveal: "ondemand",
togglerid: ""
})
</script>
这是单独的 .js 文件中包含错误的代码：
var fadeSlideShow_descpanel={
controls: [['/includes/slideshow/x.png',7,7], ['/includes/slideshow/restore.png',10,11], ['/includes/slideshow/loading.gif',54,55]],
//full URL and dimensions of close, restore, and loading images
fontStyle: 'normal 12px Verdana', //font style for text descriptions
slidespeed: 200 //speed of description panel animation (in millisec)
}
//No need to edit beyond here...
jQuery.noConflict()
