plug-ins
- A lot of plug-ins use _fnCalculateEnd and although all that is needed
in the upgrade is to remove it, since the value is calculated
automatically now, it will likely cause confusion and hassle. So I've
added this stub to prevent those errors.
- Chrome (V8) will incorrectly detect '$245.12' and similar as dates,
since V8 will strip unknown characters from a string given to
Date.parse and then attempt to parse the rest of the string - in the
example above: Dec, 245:
https://code.google.com/p/v8/source/browse/trunk/src/dateparser-inl.h#72
- The fix implemented to to check for a leading a-zA-Z, number or +-.
Although this isn't a perfect match for what Chrome does, it, I think,
a good enough effort to chatch nearly all particular use cases.
- Additionaly, V8 will try to parse a single number passed into
Date.parse - 1-12 are months, 32+ are years. As such, the numeric type
detection much be a highter priority than the date detection, since
Chrome might incorrectly use a column as a date. It would sort
correctly, but it isn't "correct".
- The take away from this is that Date.parse cannot be used for date
format validation on its own...
1D arrays.
- The method implemented isn't actually 100% perfect - if you mix arrays
and scalars, then the behaviour is undefined. But that shouldn't
happen in DataTables. Will look into it further, though
- This is actually a little more complex than it might first appear
since any classes which have been added by DT_RowClass need to be
removed. We can't just bindly remove all classes, so we need to track
that classes have been added in a private variable.
- It appears that ti is impossible to know in CSS if a table doesn't
have a tfoot element reliably and cross browser, so I've added a class
which is added to the table automatically if the table has no footer
or the fotoer is empty to complete the styling of the table.
- Fixed error when there are no cells in an empty TR row in the footer.
- With the change to camelCase, it is easier to extend the usageof
optiosn now, and in this case I've allowed the `orderFixed` (formally
`aaSortingFixed` parameter to be passed in as an object as well as an
array. As an object the `pre` and `post` parameters are used to
specify prefix and / or postfix ordering. Useful for gouping.
- The _pluck() function that was being used to get the tr elements
didn't remove nulls, while jQuery doesn't like removing a class from!
- Thanks to `RagingTroll` in the forums for spotting this:
http://datatables.net/forums/discussion/18651
the property being expanded is an object or not. If not, then set it to
be an empty object which will be extended. Only really effected the
`ajax` property
Based on the discussion in the forms (
http://datatables.net/forums/discussion/18456 ) the fix from 8935b8a
wasn't good enough. What was happening was that the _save_data function
was doing a deep copy of all arrays (minus the data array) so the
default sort was stil applied.
The fix is to reinstate the _fnExtend function which does a jQuery like
deep extend on objects and a shallow extend on arrays. That is extended
slightly to allow array references to be broken on initialisation, to
resolve the issue 8935b8a attempted to (sorting array would be used for
two tables for example), by an optional parameter. This should resolve
the issue correctly this time!
- This fixes DataTables/DataTables issue #241.
- Most of the properties attached are objects, so we want the references
to them, rather than a copy, so a simple assignment is all that is
needed. Strings etc will continue to work as well.
syntax paraneter names
- Data added using fnServerParams with array syntax had different
behaviour in 1.10 from 1.9. In 1.9 jQuery would create an array for
us, but in 1.10 before we create an object first, we need to create
that array ourselves. So the following code had different behaviour:
"sAjaxSource": "data/arrays.txt",
"fnServerParams": function ( d ) {
d.push(
{name: 'somekey[]', value: 'somevalue1'},
{name: 'somekey[]', value: 'somevalue2'}
);
}
In 1.10 it would have sent `somekey[] = somevalue2` but 1.9 would have
sent both as part of an array.
To maintain full compatiblity with 1.9 we need to convert this syntax to
an array - this commit does that.
I was concerned about using parameters in the brackets, but jQuery only
searches for `[]` when performing this conversion. We could use $.param
and then decode the created query string, which would be absolutely 100%
comaptible, but would involve additional code and I think this method
provides that 100% compatiblity from reading the jQuery code), and its
shorter.
- The ability to use negative numbers as a column selector for the
column data index was added recently, but that didn't include the
ability to work with negative numbers with the :visible pesudo
selector. This commit adds that ability so you can do:
`table.column("-1:visible")` to always get the right most visible
column
with :name postfix.
- Previously you could use a jQuery selector for columns by using the
:jq postfix, and names were matched otherwise. This is reversed now
for consistency with the rows and cells selectors which treat strings
as jQuery selectors without the :jq postfix.
returned undefined, null etc.
- The base issue was in the instanceof check which has a priority error,
it was:
! obj instanceof _Api
which is the same as:
(! obj) instanceof _Api
which is rubbish.
We want:
! (obj instanceof _Api)
but there is of course a wrapper function, so that needs ot be taken
into account as well. The new logic does just that.
- Because of the manipulation of the initalisation object initialisation
of multiple tables with a single jQuery call (i.e.
`$('.dataTable').dataTable();`) was broken since the second table
would see the modified init object. Need to take a coopy of the object
before entering that state.
- This could probably do with a bit of a clean up sometime...
- The displayLength option is poorly named, particularly with the new
API refering to it as the page length (page.len()) so, using the new
translation option to allow backwards compatiblity while using new
parameter names, I've updated this parameter's name and its
documentation.
- Renaming in keeping with the new terminology
- Updating example which uses it (main documentation still to be
written)
- Backwards compatible with a bit of logic to check if the old version
is being passed in
- Decided that it would be better to provide the new API by having
plug-ins extend it directly, rather than providing their own API.
Using the plugin() method it was possible to get a plug-in insta,ce
for example TableTools, but the way it should work is that TableTools
would provide a tabletools() API method, registering it as an
extension to the DataTables API objects. Further more, TableTools
should provide methods such as row().select() etc, extending the
current API rather than doing its own thing which the plugin() methods
prompted.
- No backwards compatiblity issues here as the plugin() code hasn't
shipped as a release.
- I added a static DataTable.on() method previously in the 1.10
development for a single event called `construct` which would tell us
when a table was constructed. But I've realise that since the events
that DataTables' triggers bubble up through the document, that effect
can already be achieved:
- Use:
- $(document).on( 'init.dt', function ( e, settings ) { } );
- Rather than:
- $.fn.dataTable.on( 'construct', function ( settings ) { } );
- No backwards compatiblity issues as the DataTable.on code was never
shipped, its dev code only
- Previously DataTables would only show an error message if there was a
JSON parsing error. However, if there was any other kind of error,
such as a 404, it would just silently swallow the error. THink its
best to show an error and a tech note.
