plupload上传控件错误exec(this.uid, component, action, args)

plupload上传控件错误exec(this.uid, component, action, args) --undefined is not a function

原因：Flash元素隐藏后调用控件的销毁方法就会报错，所以要在Flash元素隐藏销毁上传控件 uploader.destroy();

解决办法：

$('#loadlist').on('hidden.bs.modal', function (e) {
                uploader.destroy();
                $('#filelist').empty();
                $('.uploadProgress').hide();
                $('.uploadProgressPercent').css('width', '0%');
            });

改为

$('#loadlist').on('hide.bs.modal', function (e) {
                uploader.destroy();
                $('#filelist').empty();
                $('.uploadProgress').hide();
                $('.uploadProgressPercent').css('width', '0%');
            });

补充说明：hidden和hide的区别：hide是在隐藏窗口之前触发，hidden是隐藏窗口之后触发
