The information read from an Ajax data source can be arbitrarily complex, but still be displayed by
DataTables through the columns.data option, which is particularly useful for working with
JSON feeds in an already defined format.
The columns.data option has the ability to read information not only
from objects, but also from arrays using the same dotted object syntax as for objects. In addition to
this, when working with an array data source columns.data can process the data to combine and
display the data in simple forms (more complex forms can be defined by using columns.data as a function).
This example shows two different aspects of using columns.data to read arrays:
name[,
]).hr.0). Note that the order in which
the data can be used in the columns does not have to match the order in which it is defined in the
data source. The structure of the row's data source in this example is:
{
"name": [
"Nixon",
"Tiger"
],
"hr": [
"System Architect",
"$3,120",
"2011/04/25"
],
"office": "Edinburgh",
"extn": "5421"
}
| Name | Position | Office | Extn. | Start date | Salary |
|---|---|---|---|---|---|
| Name | Position | Office | Extn. | Start date | Salary |
The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
$('#example').dataTable( {
"ajax": "data/objects_subarrays.txt",
"columns": [
{ "data": "name[, ]" },
{ "data": "hr.0" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "hr.2" },
{ "data": "hr.1" }
]
} );
} );
In addition to the above code, the following Javascript library files are loaded for use in this example:
The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:
This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:
The following CSS library files are loaded for use in this example to provide the styling of the table:
This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.
