ECMAScript对文件夹图片幻灯片播放

代码如下：

var curContext = null;
var curWeb = null;
var picListTitle = "PictureLib";
var folderName = "PictureSlide";
var liTemp = "<li style='background-image: url({0});'></li>";

$(document).ready(function () {
    curContext = SP.ClientContext.get_current();
    curWeb = curContext.get_web();
    
    ShowSlidePics();
    
});

function ShowSlidePics()
{
    var camlQuery = SP.CamlQuery.createAllFoldersQuery();
    //var folderUrl = "/teams/ap1/gctech/DEV/PictureLib/" + folderName+"/"; ///teams/ap1/gctech/DEV
    //camlQuery.set_folderServerRelativeUrl(folderUrl);
    camlQuery.set_viewXml("<View Scope='RecursiveAll'><Query><Where><Contains><FieldRef Name='FileDirRef'/><Value Type='Text'>/PictureSlide</Value></Contains></Where></Query></View>");

    var picList = curWeb.get_lists().getByTitle(picListTitle);
    var fileItems = picList.getItems(camlQuery);
    curContext.load(fileItems, 'Include(ID, Title, FileRef)');//, FileLeafRef, FileDirRef
    curContext.executeQueryAsync(Function.createDelegate(this, onQuerySucceeded), Function.createDelegate(this, onQueryFailed));

    function onQuerySucceeded(sender, args) {
        var itemInfo = '';
        var itemEnumerator = fileItems.getEnumerator();

        while (itemEnumerator.moveNext()) {
            var item = itemEnumerator.get_current();
            itemInfo += liTemp.replace("{0}", item.get_item('FileRef'));
        }

        $("#divBanner ul").html(itemInfo);

        StartBindSlide();
    }
    function onQueryFailed(sender, args) {
        console.log('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }

    function StartBindSlide()
    {
        $('#divBanner').unslider({
            speed: 500,     // speed
            delay: 3000,    // delay
            keys: true,     // enable Key
            dots: true      //  dots
        });

        var unslider = $('#divBanner').unslider();
        $('.unslider-arrow').click(function () {
            var fn = this.className.split(' ')[1];
            //  Either do unslider.data('unslider').next() or .prev() depending on the className
            unslider.data('unslider')[fn]();
        });
    }
}
