Get value from first cell in a selected row using v1.10 beta 2

MikeS

I'm using the code found in the "Row Selection and Deletion (Single Row)" example as a start for something I'd like to do in my own code. The example code is:
[code]
$(document).ready(function() {
var table = $('#example').DataTable();

$('#example tbody').on( 'click', 'tr', function () {
if ( $(this).hasClass('selected') ) {
$(this).removeClass('selected');
}
else {
table.$('tr.selected').removeClass('selected');
$(this).addClass('selected');
}
} );

$('#button').click( function () {
table.row('.selected').remove().draw( false );
} );
} );
[/code]

I would like to determine the value of the first cell of the selected row because it contains an ID that I need. How can I get that value? I have a feeling that table.row('.selected'). is going to do it but I can't figure it out. I've looked at the API and scanned this forum and am stuck trying to find the answer.

Unfortunately, I don't have an external site to point you to an example :(

Are you trying to do something with the data only when the row is selected?

[code]
table.cell('.selected', 0).data()
[/code]

will get you the first select which has a row with a class `selected` and the first cell in the row ( http://next.datatables.net/reference/api/cell() ).

If you want the node, use the `cell().node()` method and then you can read the `id` parameter from it.

Thanks Allan. That did it for me.

So...in the button click function, if I delete the line of code to remove the selected row, and substitute alert(table.cell('.selected', 0).data());, the value in the first cell of the selected row will be displayed?

How would I get an array of cell data from multiple rows with the class .seleted?

This obviously doesn't work but it's the most I could come up with..

var cellData = [];
var rowCount = Table.cell('.checked')indexes().length;

for(var i=0;i<rowCount;i++) {
cellData.push(Table.cell('.checked', 0).data());

}

Does:

var data = Table.cells('.checked').data();

do what you are looking for?

Does that above not work for you? If not, please link to a test page, as per the forum rules, showing the issue so it can be debugged.
