jQuery Slideshow在IE8中不起作用，在Safari / Firefox中运行良好

我即将到来的婚礼网站（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，在发出邀请函之前，我真的希望我的网站看起来很清晰。我对jQuery一无所知。因此，我遇到了复制和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 查尔：3 代码：0 URI：http://www.hilaryandmatthew.com/includes/slideshow/fadeslideshow.js

这是我的图像数组传入函数'fadeSlideShow（settingarg）'的代码

<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", "", "", ""],
                ["images/ss9.jpg", "", "", ""],
                ["images/ss10.jpg", "", "", ""],
                ["images/ss11.jpg", "", "", ""],
                ["images/ss12.jpg", "", "", ""],
                ["images/ss13.jpg", "", "", ""],
                ["images/ss14.jpg", "", "", ""],
                ["images/ss15.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>

以下是单独的.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()

function fadeSlideShow(settingarg){

    this.setting=settingarg
    settingarg=null
    var setting=this.setting
    setting.fadeduration=setting.fadeduration? parseInt(setting.fadeduration) : 500

为了进一步澄清，我个人花了一些时间找到它...... 

<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", "", "", ""],

        ],

答案 1 :(得分：4)

问题直接出现在您发布的第一个代码块中：Internet Explorer不喜欢对象和数组中的尾随逗号。
您只需要从imagearray中的最后一个元素中删除尾随逗号，它应该可以工作（如果没有，请检查其他数组和对象是否存在同一问题）
