From: Vincent Petry Date: Fri, 4 Apr 2014 12:34:07 +0000 (+0200) Subject: Fixed file sorting to work with scrolling X-Git-Tag: v7.0.0alpha2~339^2~10 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=f6586f6bdfe8f5b2175d9ee5e833ecb4ccbc5f7d;p=nextcloud-server.git Fixed file sorting to work with scrolling The FileList.files model is now updated with file operations. Adding files to the list will add to the model first, then to the DOM. If the insertion point isn't visible yet, the file won't be added to the DOM until the user scrolls down. Updated unit tests to include checking for the correct insertion point. --- diff --git a/apps/files/js/filelist.js b/apps/files/js/filelist.js index 02754d7acbb..53bb3a5c868 100644 --- a/apps/files/js/filelist.js +++ b/apps/files/js/filelist.js @@ -30,6 +30,20 @@ window.FileList = { pageNumber: 0, totalPages: 0, + /** + * Compare two file info objects, sorting by + * folders first, then by name. + */ + _fileInfoCompare: function(fileInfo1, fileInfo2) { + if (fileInfo1.type === 'dir' && fileInfo2.type !== 'dir') { + return -1;
