Custom button form message

andreas.heckwolf@menturagroup.com

Description of problem:
I have a custom button "Delete All" which deletes all selected rows based on search. Before delete function, I want to display a form message warning the user about the delete all. I am unable to show the form message though I have the details.

{
                text: '<i class="fa fa-trash"></i> Delete all',
                className: 'btn btn-danger btn-editor-remove',
                
                formMessage: function ( e, dt ) {
                    return 'Do you want to delete all selected rows?';
                },
                action: function () {
                   
                        table.ajax.url("/xxxxxxxx?contentType=application/json");
                        table.page(0);
                        table.ajax.reload();
                        // set the URL back to the normal browsing call
                        table.ajax.url("/xxxxxxxxxxxxx?contentType=application/json");
                    
                }
            }

Also there is already and single row delete button on the table. I could use the simple javascript confirm dialog, but it looks quite different from form message. Please help.

I've never used this but from what I gather the formMessage option is used with Editor buttons, like this example. Are you using this with the Editor?

Hello Kevin,

Yes I am using this button as part of Editor buttons. I am using CRUD buttons along with this custom button. I need a warn form message for this custom button, but even after defining it in the button, it does not pup-up. Let me know if I am missing something.

In the example you have shown, the buttons have used 'extend' keyword. I have not used it as it is a custom button. Is it Ok to use 'extend' for custom button also? (Already there is a button extending 'remove' to delete a row)

Thanks
Andreas

I'm not sure if you're aware, but the standard Delete button does that behaviour already. If you look at this example, select a couple of rows, and then press "Delete", you'll see the warning message and then all rows are removed.

It might be useful if you tell us what you're trying to achieve, as there may be an alternative way of doing it,

Hello Colin,

I am using Search box to filter out the rows and then Click "Delete All" to delete the selected rows from the search. This comes handy when we have many rows to delete based on search criteria.

Thanks

I think this is doing what you're after - http://live.datatables.net/vehebuxu/1/edit

There's a new button that will delete all records returned by a search - I've tweaked it so that if there isn't an active search, it does nothing, but you can customise that,
