属性 uploader 必须是 FileUploader的一个实例。
属性 options 可能是 {FileItem} 的设置或者自定义设置。
属性 filters 可能是用,隔开的过滤器名称，比如： 'filterName1, filterName2'，这些过滤器必须如下预定义：

uploader.filters.push({name:'filterName1', fn:function() {/* your code here */}});
uploader.filters.push({name:'filterName2', fn:function() {/* your code here */}});

• nv-file-select

• nv-file-over
