I have a list of Data I get from dynamic inputs like this ones

   FirstNames : Person1 FN, Person2 FN, Person3 FN, ...
   LastNames : Person1 LN, Person2 LN, Person3 LN, ...

The list is dynamic and I’m Getting the values by input Name like this

    var FirstNames = $("input[name='FirstName']").map(function(){return $(this).val();}).get();

I want to pass these and many others to my C# backend as an array like This

  details:[
   0: {FirstName: 'Person1 FN', LastName: 'Person1 LN'}
   1: {FirstName: 'Person2 FN', LastName: 'Person2 LN'}
   ....................................................
   N{FirstName: 'PersonN FN', LastName: 'PersonN LN'}
  ]

I tried many different approaches like split() & Push() as below

  let FNs = [];
  let FN = FirstNames.toString().split(',');
  console.log("Splitted First Names : "+TFNs);

  $.each(TFNs, function(){
      FNs.push({FirstName:$(this)}.toString());
  });
  console.log("First Names[] : "+FNs);

Edit : Added Form markup(dynamic) & JS Save() Function

Here is the form (dynamically generated)

function GenerateFrms(Id) {
         //alert('Function Scripts');
        $("#FrmContainer").empty();
        var html = "";



        $.ajax({
            type: "POST",
            url: "WebService.asmx/GenerateForms",

            dataType: "json",

                try {
                    for (var i = 0; i <= data.d.length; i++) {
                   
                        if (data.d[i].Persons != "0") {

                    console.log(e);
                }
            },
            error: function (xhr, status, e) { alert(xhr.responseText); }
        });

    }

The Script function with Sample static data I’m working with now(I want get them dynamically from the above form)

function Save() {
        $('#create').prop('disabled', true);
        
        //Reading Values from the respective inputs/select
        var Titles = $("select[name='Title']").map(function(){return "Title:"+$(this).val();}).get();
        var FNames = $("input[name='FirstName']").map(function(){return $(this).val();}).get();
        var LNames = $("input[name='LastName']").map(function(){return $(this).val();}).get();
        var DOBs = $("input[name='DOB']").map(function(){return "DOB:"+$(this).val();}).get();


        //here I want to put them in array like `details[]` array below
        setTimeout(function () {

            let details=[];
            
            details.push({
                Title:"Mr.",
                FirstName:"Person1 FN",
                LastName:"Person1 LN",
                DOB:"1990-05-20"
            });
            
            details.push({
                Title:"Mrs.",
                FirstName:"Person2 FN",
                LastName:"Person2 LN",
                DOB:"2001-06-18"
            })
             console.log(details);

            var DataCarrier = {
                Id: Id, //From Query string
                 PersonsDetails:details
                };

               $.ajax({
                type: "POST",
                url: "WebService.asmx/SavePersons",
                data: JSON.stringify(DataCarrier),
                contentType: "application/json",
                dataType: "json",
                success: function (data) {
                    try {
                        if (data != null) {
                            setTimeout(function () { window.location = "destinationPage.aspx?Id=" + Id; }, 500);
                        }
                       
                    } catch (e) {
                        console.log(e);
                    }
                },
                error: function (xhr, status, e) { alert(xhr.responseText); }
            });

            }, 5000);
        }

And the button

 <input id="btnSave" class="btn btn-effect btn-book px-5" type="button" value="Continue" onclick="Save();" />

But I’m getting them as

 [object Object],[object Object],[object Object],[object Object],[object Object]

I also tried .toString() but nothing changes, And console.log("FNs : "+json.stringify(FNs)); is throwing error.

How can I process these data as mentioned above before passing them to the backend? What I’m doing wrong? Is there a better way to do what I want achieve?

  1. Chosen as BEST ANSWER

    First step is to read the values from the inputs or select

      //Reading Values from the respective inputs/select
    var Titles = $("select[name='Title']").map(function() { return $(this).val(); }).get();
    var FNames = $("input[name='FirstName']").map(function() { return $(this).val(); }).get();
    var LNames = $("input[name='LastName']").map(function() { return $(this).val(); }).get();
    var DOB = $("input[name='DOB']").map(function() { return $(this).val(); }).get();
    

    Then split the values into array

     //splitting the values into arrays
    let TL = Titles.toString().split(',');
    
    let FN = FNames.toString().split(',');
    
    let LN = LNames.toString().split(',');
    
    let BD = DOB.toString().split(',');
    

    After that you can push them into the details[] array using for loop like this

    let details = [];
    
    for (var i = 0; i < FNames.length; i++) {
        details.push({
            Title: TL[i],
            FirstName: FN[i],
            LastName: LN[i],
            DOB: BD[i],
            TravllerType: TT[i]
        });
    }
    console.log(JSON.stringify(details));
    

    Note: if you console.log(details); you will find out that its object:Object stuff, to get around this, we stringify it.

    finally incorprate all that into your SavePersons() function

    function SavePersons() {
    
            $('#create').prop('disabled', true);
    
            //Reading Values from the respective inputs/select
            var Titles = $("select[name='Title']").map(function () { return $(this).val(); }).get();
            var FNames = $("input[name='FirstName']").map(function () { return $(this).val(); }).get();
            var LNames = $("input[name='LastName']").map(function () { return $(this).val(); }).get();
            var TravllerTypes = $("input[name='TravllerType']").map(function () { return $(this).val(); }).get();
            var DOB = $("input[name='DOB']").map(function () { return $(this).val(); }).get();
    
    
            //splitting the values into arrays
            let TL = Titles.toString().split(',');
    
            let FN = FNames.toString().split(',');
    
            let LN = LNames.toString().split(',');
    
            let TT = TravllerTypes.toString().split(',');
    
            let BD = DOB.toString().split(',');
    
    
            setTimeout(function () {
    
                let details = [];
    
                for (var i = 0; i < FNames.length; i++) {
                    details.push({
                        Title: TL[i],
                        FirstName: FN[i],
                        LastName: LN[i],
                        DOB: BD[i],
                        TravllerType: TT[i]
                    });
                }
                console.log(details);
    
                var DataCarrier = {
                    Id: Id,
                    TravelersDetailsTT: details
    
                };
    
                $.ajax({
                type: "POST",
                url: "WebService.asmx/SavePersons",
                data: JSON.stringify(DataCarrier),
                contentType: "application/json",
                dataType: "json",
                success: function (data) {
                    try {
                        if (data != null) {
                            setTimeout(function () { window.location = "destinationPage.aspx?Id=" + Id; }, 5000);
                        }
                       
                    } catch (e) {
                        console.log(e);
                    }
                },
                error: function (xhr, status, e) { alert(xhr.responseText); }
            });
    
            }, 5000);
        }
    

    it may not be the best answer but it works and I tested it. any improves are welcome. in the mean time I hope it helps.


  2. I think the index of firstName and lastName in your array is identical so

    var FirstNames = $("input[name='FirstName']")
    .map(function(){return $(this).val();}).get();
    var LastNames = $("input[name='LastName']")
    .map(function(){return $(this).val();}).get();
    
    var FN = FirstNames.map((FN,index) => {
       return {{FirstName: FN, LastName: LastNames[index]}
    })
    

    It should be something like what you want
