Get the selected value of the checkbox

lenamtl

Hi,

I'm using Select and jquery-datatables-checkboxes https://github.com/gyrocode/jquery-datatables-checkboxes

I'm retriving the selected value like this
var tempContactId = table52.rows( { selected: true } ).data().pluck(2).toArray();

I'm wondering is there another way using Datatables function to get the same result, I'm wondering if there is a better way or this code is just ok?

Note I'm not using server-side process.

Thanks

That is the way to get an array of selected rows where the array contains the values in column 2. Are you trying to achieve something different?

If column with index 2 is the column containing checkboxes, you could use:

table.column(2).checkboxes.selected()

For all other columns I thought you could use selector-modifier as shown below, however it doesn't work in my tests, could be a bug in the DataTables possibly ?

table.column(2, { selected: true }).data()

I created an example where column().data() doesn't work as expected, maybe Allan can take a look at it.

table.column(0, { selected: true } ).data();

This won't work with row selection. You need to use rows() when selecting by rows.

Maybe then documentation is not 100% correct, since column() API method documentation states that selector-modifier can be used for operations which involve rows.

Could be. Allan can comment on that part.

Maybe Allan's answer in this thread will help explain why it doesn't work as expected.

It is working as expected, though possibly counter-intuitively.

By default, the Select extension will select rows - so when you use column() and selector-modifier {selected: true}, since no columns are selected, everything is returned.

If you set select.items to columns, so you select the columns, then you do get what you expect - see example here.

Hope that helps make it clearer. So for you, Kevin's suggestion of rows() is the way to go.
