So that they're together with the other resources instead of in site-package/gramps. Aside from a better source and installation layout, this makes it easier to bundle them. svn: r22576

// TODO: on resize (at least when wrapping within a table), the arrow is pushed down to the next line
|

|

// TODO: add options for advanced paging template
|

// TODO: general cleanup and refactoring, commenting
|
|
// TODO: detailed Exception handling, logging

|
// TODO: FF2, up arrow from bottom has erratic scroll behavior (if multiple flexboxes on page)
|
|
// TODO: FF2 (and maybe IE7): if maxVisibleRows == number of returned rows, height is a bit off (maybe set to auto?)
|
|
// TODO: escape key only works from input box (this might be okay)
|
|
// TODO: make .getJSON parameters (object and callback function) configurable (e.g. when calling yahoo image search)
|
|
// TODO: escape key reverts to previous value (FF only?) (is this a good thing?)
|
|
|
|
// TEST: highlightMatches uses the case of whatever you typed in to replace the match string, which can look funny
|
|
// TEST: handle pageDown and pageUp keys when scrolling through results
|
|
// TEST: allow client-side paging (return all data initially, set paging:{pageSize:#}, and ensure maxCacheBytes is > 0)
|
|
// TEST: accept json object as first parameter to flexbox instead of page source, and have it work like a combobox
|
|
// TEST: implement no results template
|
|
// TEST: implement noResultsText and class
|
|
// TEST: watermark color should be configurable (and so should default input color)
|
|
// TEST: exception handling and alerts for common mistakes
|
|
// TEST: first example should use defaults ONLY
|
|
// TEST: add property initialValue, so you can set it when the flexbox loads
|
|
// TEST: handle hidden input value for form submissions
|
|
// TEST: how can we allow programmatically setting the field value (and therefore hidden value). add jquery function?
|
|
// TEST: use pageSize parameter as threshold to switch from no paging to paging based on results
|
|
// TEST: if you type in an input value that matches the html, it might display html code (try typing "class" in the input box)
|
|
// TEST: don't require all paging subprops (let default override)
|
|
// TEST: when tabbing from one ffb to another, the previous ffb results flash...
|
|
// TEST: IE7: when two non-paging ffbs right after each other, with only a clear-both div between them, the bottom ffb jumps down when selecting a value, then jumps back up on mouseover
|
|
// TEST: FF2, make sure we scroll to top before showing results (maxVisibleRows only)
|
|
// TEST: if maxVisibleRows is hiding the value the user types in to the input, scroll to that value (is this even possible?)

// TEST: make sure caching supports multiple ffbs uniquely
