In some tables you might wish to have some content generated automatically. This can be done in a number of ways:
columns.render for
content that is dynamic (i.e. based upon the row's data)
columns.defaultContent for static content (i.e. simple strings)
This examples shows the use of columns.defaultContent to create a button element in the last column of the table. A simple jQuery
click event listener is used to watch for clicks on the row, and when activated uses the row().data() method to get the data for the row and show a
bit of information about it in an alert box. This is a simple use case, but it can be built up to be arbitrarily complex.
Note also that the columns.data option for the column has been set to null to indicate that the column has no information
contained in the data source object.
The Javascript shown below is used to initialise the table shown in this example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | $(document).ready(function () { var table = $('#example').DataTable({ ajax: 'data/arrays.txt', columnDefs: [ { targets: -1, data: null, defaultContent: '<button>Click!</button>', }, ], }); $('#example tbody').on('click', 'button', function () { var data = table.row($(this).parents('tr')).data(); alert(data[0] + "'s salary is: " + data[5]); });}); |
In addition to the above code, the following Javascript library files are loaded for use in this example:
