Directives（指令）

• nv-file-drop

<!--最少配置--><elementnv-file-dropuploader="{FileUploader}"></element><!--最多配置--><elementnv-file-dropuploader="{FileUploader}"options="{Object}"filters="{String}"></element>

属性uploader必须是 FileUploader的一个实例。
options可能是{FileItem}的设置或者自定义设置。
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(){/*yourcodehere*/}});
uploader.filters.push({name:'filterName2',fn:function(){/*yourcodehere*/}});

• nv-file-select

<!--最少配置--><inputtype="file"nv-file-selectuploader="{FileUploader}"/><!--最多配置--><inputtype="file"nv-file-selectuploader="{FileUploader}"options="{Object}"filters="{String}"/>

• nv-file-over

<!--最少配置--><elementnv-file-overuploader="{FileUploader}"></element><!--最多配置--><elementnv-file-overuploader="{FileUploader}"over-class="{String}"></element>
