Get inputs values from a form : JavaScript

Question

I have a dynamic form Like this in image :

How can I get each adult separately in variable like this :

[["Mr.","aa","bb"],["Mrs","cc","dd"],["Dr.","ee","ff"]]

I submit the form in Ajax, so I need this data serialized. I defined class add_pax_adult_x and x is the number of each adult. I have this code below. every this is ok and I can return the data but I need to return this format as I mentioned.

$(document).on('submit','#passenger_details_form',function(event){

var toatalAdults = [];
        var adultsPax  = [];
        for(var x=1; x<=$('#adults').val(); x++){
            var inputs = $(".add_pax_adult_"+x);

            for(var i = 0; i < inputs.length; i++){
                adultsPax.push($(inputs[i]).val())
            }
            toatalAdults.push(adultsPax);

        }

        alert(toatalAdults);

});

<div class="col-sm-5 adultsDiv" style="padding-left: 0">
               
                        <select id="adults" required="" class="form-control adults" name="no_of_adults">

You can use document.querySelector('...') to select and read the values from the inputs. — Marco

Also to answer this question completely you need to post the markup of the form. — Marco

Try below code

<?php if(isset($_GET['task']) && $_GET['task'] == 'send'){
$request = [];
foreach($_POST['pax_title'] as $k=>$pax_title){
    $request []=[$pax_title,$_POST['adult_fname'][$k],$_POST['adult_lname'][$k]];
}
print_r($request);exit(); } ?>

You say you need the data serialized, well you're in luck, just use the <form Element>.serialize() method.

i.e. You have this form

<form id="myForm">
    ...
</form>

In your script, just do this

var serialized=$("$myForm").serialize();

Voila, it is now serialized in standard AJAX notation.
