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]();

        });

    }

}
