Rational for this is that the number renderer expects a number
input, not HTML, but if non-numeric input is given the value is just
returned (now escaped) - for example an empty string.
- I just updated my PHP and HTML Tidy was not installed which resulted
in the examples in the dist repo all being rewritten unfortunately.
This should stop that happening again.
- If d or objectRead were truthful then the row's data object would be
replaced with an empty object. This was one shortcut in code too many!
- Relates to thread 29530 with thanks to idleog.
- Bootstrap is proving to be a far more popular theme for DataTables -
this example comes from back in the day when jQuery UI theming was
first added, so it is no longer required.
DataTables which character is used as a decimal place in the table's
data, so that number which are formatted using characters other than a
dot as the decimal place can be correctly detected and sorted.
- A large part of the world uses the comma as a decimal place, so it
makes sense to have this option built-in directly to DataTables,
rather than needing to use plu-in sorting types as before:
http://en.wikipedia.org/wiki/Decimal_mark
- However, the decimal place character cannot be detected automatically
since there are far to many ambiguities. As such, a new
`language.decimal` option is defined which is passed through to the
type detection functions. The type detection functions can then use
that character to alter their detection functions to transform numbers
into the dot formatted equivilent for parsing in Javascript.
- The numeric sorting methods have been bundled together in the function
`_addNumericSort` which is called when a character is given for the
decimal mark, adding the sorting functions required specifically for
that mark. This means that any character at all can be added, while
keeping the table's sort performance as it was.
- Code size in increased a little for this new feature, but a lot of
work has been done to keep it to a minimum (while still optimising for
the most common use case of a dot decimal place), and this is a good
feature to have in DataTables' core code.
- All required documentation added and updated.
- Special thanks to Tobias Bäthge for suggesting and sponsoring this
feature.
