button value

yskapell

Hello all,

I have this code on a button

                        {
                            text: "Copy",
                            action: function ( e, dt, node, config ) {
                                var tblData = this.rows('.selected').data();
                                //console.log(tblData);
                                var tmpData;
                                $.each(tblData, function(i, val) {
                                    tmpData = tblData[i];
                                    count = count + 1;
                                    $.post('copy.php', {
                                        data: tmpData
                                    }, function(response) {
                                        //$('#content').html(response);
                                        console.log(response);
                                        
                                    });
                                });
                                return totalCount = count; 
                            }
                        },

Can I pass the totalCount in another button ?

for examples to have something like this

{
     text: "Preiview ("+totalCount+")",
      ...
}

Yep, set a global variable and update the other buttons text on click of the first button.

Sounds like you want to change the button text. To do this use button().text().

I want to update with the row I select to copy..

I'm not sure what this means. Please elaborate.

If I copy 5 rows the Preview button to change to Preview (5), if I copy 1 to change Preview (1) etc

Maybe something like this:

{
    text: "Copy",
    action: function ( e, dt, node, config ) {
        // Get selected rows
        var rows = this.rows('.selected');

        // Set the Preview button text to the count of rows
        dt.button( x ).text( "Preview (" + rows.count() + ")" );

        // Get the selected rows data
        var tblData = rows.data();
        //console.log(tblData);
        var tmpData;
        $.each(tblData, function(i, val) {
            tmpData = tblData[i];
            count = count + 1;
            $.post('copy.php', {
                data: tmpData
            }, function(response) {
                //$('#content').html(response);
                console.log(response);
                 
            });
        });
        return totalCount = count;
    }
},

I didn't test this. First it gets the selected rows. Uses count() to get the row count to set the other button via button().text(). Replace x with the appropriate button-selector.

Does your copy.php accept multiple rows? If so you can send them in one request. Change var tblData = rows.data(); to var tblData = rows.data().toArray(); to get a Javascript array that can be sent.
