Javascript Library read subfield repeatable field

[aberaldo]

I have a repeatable field with a subfield called 'subtotal' i want to read each subfield subtotal present in each row of the repeatable. How can i achieve this?

Hey @aberaldo

The subfield() supports the row number argument.

Try:

crud.field('features').onChange(function(field) {
    var i = 1;
    var total = 0;
    while ((crud.field('features').subfield(`subtotal`,i).value != undefined)) {
        var subtotal = crud.field('features').subfield(`subtotal`,i).value; //subfield() supports row number argument.
        console.log("subtotal",subtotal);
        total+=Number(subtotal);
        i++;
    }
    console.log("total",total);
}).change();

@pxpm can you suggest a better way to loop ?

Hi! @karandatwani92 thank you for the response!.
Finally i did like this using JQuery

jQuery('div[data-repeatable-identifier="up_services_data"]').each(function (index, value) {
  let totalUp = jQuery('input[data-repeatable-input-name="up_total_cost"]', value).val();
  ....
});

But if there is a way using the Backpack javascript library i think is better
