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

• 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}"/>
