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.

<h1>DataTables example <span>- Custom data source property</span></h1>
|
|
|
|
<div class="info">
|
|
<p>When loading data from an Ajax source, by default, DataTables will look for the data to use in the
|
|
<code>data</code> parameter of a returned object (e.g. <code>{ "data": [...] }</code>). This can easily
|
|
be change by using the <code>dataSrc</code> option of the <a href=
|
|
"//datatables.net/reference/option/ajax"><code class="option" title=
|
|
"Initialisation option">ajax</code></a> initiation option.</p>
|
|
|
|
<p>The <a href="//datatables.net/reference/option/ajax.dataSrc"><code class="option" title=
|
|
"Initialisation option">ajax.dataSrc</code></a> has a number of ways in which it can be used:</p>
|
|
|
|
<ul>
|
|
<li>As a string (e.g. <code>dataSrc: 'myData'</code>) - obtain data from a different property in
|
|
the source object.</li>
|
|
<li>As an empty string (e.g. <code>dataSrc: ''</code>) - the data source is not an object but an
|
|
array.</li>
|
|
<li>As a function (e.g. <code>dataSrc: function(json) {}</code>) - a function can be used to
|
|
transform the data from one source format to another (for example you could convert from XML to a
|
|
Javascript object). The value returned from the function is used as the data for the table.</li>
|
|
</ul>
|
|
|
|
<p>The example below shows <a href="//datatables.net/reference/option/ajax.dataSrc"><code class=
|
|
"option" title="Initialisation option">ajax.dataSrc</code></a> being used as a string to get the data
|
|
from a different source property, in this case <code class="string" title="String">demo</code> but it
|
|
could be any value, included a nested property by using standard dotted Javascript object notation.</p>
