Example of Multi Select Datatable Within a Form, passing selected values to Servlet on Submit

ggiavelli

Hi,

I have a working multi-select datatable. How can I use it in a form with a submit button, calling a java servlet with the data values from a particular column (say col 0). Do I have to get into jQuery and maintain an array of selections or should be an API call to get the data for submit. Can some one show a simple example?

Hi @ggiavelli ,

Are you expecting to pass the column values with Ajax? If so, use ajax.data to pass the values. And to get the values, use rows({selected:true}).data().pluck(0).

Cheers,

Colin

I am getting all the datatable values and some formatting info. Is there a way to clean this up on the client side so I only get the first columns values?

e.g.
$('button').click( function() {

            var data = table.rows( ['.selected'] ).data().pluck(0);
            var stringdata = JSON.stringify(data);
            alert(
                "The following data is selected: \n\n"+
                stringdata
            );
            return false;
        } );

The pluck() API can get column 0 using pluck(0) of using arrays. However if you are using columns.data then use the object property as shown in the docs.
