- This commit sees the number of built in type detection and sorting
functions increase to cover the most common cases of use of plug-ins
for DataTables (witht he exception of dates, for which a new first
class plug-in will be created). Specifically, DataTables now has built
in support for:
- Dates (Date.parse())
- Numeric sorting
- Formatted numbers sorting (including currency and thousands
seperators)
- Numbers wrapped in HTML (link tags for example)
- Formatted numbers in HTML
- HTML
Although the numeric sorting plug-ins could have been collapsed down to
just two plug-ins (rather than 4) I decided to do it this way to allow
type based filter formatters to be used with the formatted number types
to allow search for "100,000" or "100000" to match the same data. This
is not built in, but it is possible (and might be in future).
- The goal with these additional functions is to enhance the abilities
of DataTables out of the box to cover the most common cases for data
usage - DataTables is all about making data in tables more accessable
after all! The size cost is ~300 bytes for these additional functions
- In the case of filtering, if there is no filtering extension for the
column type, then the basic string based filter formatting is
performed (i.e. string is always the fallback - there can't be an
error because a function isn't there).
- This commit matches that behaviour in sorting. If you define a column
type as something for which there is no column sorting function, then
the string type will be used rather than resulting in a javascript
error.
- Automatic column type detection was a real weak point of v1.9- - it
did basically work, but if you then updated a row that didn't match
the current data type it would always end up as a string. A good
example of this is the ambiguous date "06-06-13" (is it dd-mm-yy or
mm-dd-yy?). If it was detected as dd-mm-yy and then you add '05-20-13'
to the column (or update an exisiting cell), the type would not match
the exisiting value that thus failover to a string.
- Type detection is now more rigorous, but still optimised (since it
has the potential to take up a significant amount of time). When a row
is added or updated, or a cell is updated, the exisiting type is
removed from the target column(s) and then, before sorting or
filtering, the _fnColumnTypes function checks to see if any column
needs to be type detected and do so if needed. This approach allows
multiple rows to be added (for example) before the draw is performed and
the type actually needs to be calculated.
- In future I'd like to have a 'data-ready' type event which will tell
DataTables, and any of its components that something wants to work with
the data in the table and it should prep the data. The counterpart would be
a 'data-invalid' flag which would be set on update, add etc so it knows
when an update is needed.
- The oApi option wasn't being attached correctly to either the settings
object or the instance, so plug-ins were breaking. This adds the alias
back in.
- If you were multi-column sorting, and didn't have shift depressed and
click on the first column in the sorting priority, the multi-column
sort would be retained. Non-shift click on any of the other columns
would reduce to a single column sort, so match here
- This is a fairly far reaching commit in that the DataTables.ext object
is updated to primarily use camelCase, just like the rest of the 1.10
API. The old notation is still available for compatiblity, but
deprecated.
- While working in this area, I've made a number of updates:
- .model.ext has been removed - that was redundant and not useful.
DataTables.ext is where the plug-ins for DataTables will live and
will be correctly publically documented as such.
- Type based actions (detection, sorting and filter) now live in a
`type` namespace to make it clear that they are type based.
- Internal references to .ext updated to use the new parameters. We
could use the old ones since they are fully backwards compatible,
but I'd rather set the standard by using the modern ones.
- JSDoc comments for .ext updated
- Extension examples updated
- When creating the new visiblity methods, I forgot to have the table do
a scroll draw to have the columns align correctly for the header and
body. This commit fixes that.
- Also update the column visiblity example to use jQuery events rather
than DOM0 events.
- Previously you'd need to use initComplete and columns.adjust() to take
account of the data that was loaded by Ajax. Now this will be done
automatically. It does mean a few more clock cycles, but I think
that's a tradeoff that is worth it.
- Alias the static methods to camelCase and hungarian varients:
- versionCheck()
- tables()
- isDataTable()
- Small updates in styling of the static functions
- I'd previously added columns().cache() which gets the cached
information about filtering or sorting, but this rounds the API off,
extending that also to rows and cells:
- rows().cache()
- row().cache()
- cells().cache()
- cell().cache()
Fix: I've removed the third entry in the aaSorting array, as the issue
was that after using order() that entry wasn't present. It was a bit
confusing as well, so it is now replaced with a property (_idx on the
aaSorting entries) which indicates the current sorting index (in
asSorting) - and this property is optional. If not given, it is looked
up or 0.
build and commit scripts to keep the src and build repos in sync.
Dev: Update the dataTables main file to the latest build which was
accedentally committed. Just a couple of little dev fixes - no API
changes.
