 //上传多文件
    functionUploadMultiFile() {

            //选完文件后，是否自动上传。

            server: '../../Document/Art/UploadFile',
            //选择文件的按钮。可选。
            //内部根据当前运行是创建，可能是input元素，也可能是flash.
            pick: '#picker',
            //不压缩image, 默认如果是jpeg，文件上传前会压缩一把再上传！
            resize: false
