concatenate text input fields on submit

I have a form that allows me to dynamically add fields. For example one field is named "part_numbers". When the renders in the browser it renames each field sequentially using this syntax: parts[parts][0][part_numbers]

so for instance, if my form has the 3 part_numbers fields it will now have:
parts[parts][0][part_numbers]
parts[parts][1][part_numbers]
parts[parts][2][part_numbers]

I need to take each of these values and concatenate them with a comma separator. How can I do that and should it be attached to the submit function?

thanks.

Try again :)

What do you get in the alert with the following code and what don't you want or what it miss ?

$("form").submit(function() {
  part_numbers = "";
  $.map( $("form").serializeArray(), function(el,i) { part_numbers += ( ((i>0)?"|":"") + el.value) });
  $("#part_number").val( part_numbers );
  alert( part_numbers );
});

that gets me closer. It returns the values of all fields in my form in the alert.

So what do you get in the alert with the following code and what don't you want or what it miss ?

This line put all this value in a field with the id "part_number" : $("#part_number").val( part_numbers );

<input name="part_number" id="part_number" type="hidden" />

if this field did not exist you can create it on the fly before using : $("body").append("<input name=\"part_number\" id=\"part_number\" type=\"hidden\" />";

$("form").submit(function() {
  part_numbers = "";
  $.map( $("form").serializeArray(), function(el,i) { part_numbers += ( ((i>0)?"|":"") + el.value) });
  $("body").append("<input name=\"part_number\" id=\"part_number\" type=\"hidden\" />";
  $("#part_number").val( part_numbers );
  //alert( part_numbers ); checking off
});

Could you use a class to identify which fields are to be concatenated, as below:

jQuery(document).ready(function(){

  $("#click-me").click( function() {
    var pick = [];
    $(this).closest("form").find(".concatenate-me").each( function() { pick.push( $(this).val() ) });
    alert( pick.toString() );
  });

});

Open in new window

<form>
  <input class="concatenate-me" value="A" />
  <input class="concatenate-me" value="B" />
  <input class="concatenate-me" value="C" />
  <input class="concatenate-me" value="Z" />
  <input id="click-me" type="button" value="Submit" />
</form>

The issue now is that it is returning every value within my form as part of "part_numbers" value:

Whereas what I need is to take the part_numbers field (which in this case has values of 5555 and 444) and concatenate them together so that part_numbers = "5555, 444"

leakim971

What about :

$("form").submit(function() {
  part_numbers = "";
  $.map( $("[name^='parts[parts]']").serializeArray(), function(el,i) { part_numbers += ( ((i>0)?"|":"") + el.value) });
  $("#part_number").val( part_numbers );
  alert( part_numbers );
});

That's closer, however the row of fields that gets cloned actually has 4 fields each with the "parts[parts]" at the beginning of their name. The last segment of the name is [part_numbers] and is unique to each field. Is there a way to write it to fetch that?

ASKER

i don't know if that was clear enough, here is a sample of the names of each of the four fields:

parts[parts][0][part_numbers]
parts[parts][0][nsns]
parts[parts][0][quantity_required]
parts[parts][0][condition_required]

So if we can isolate them based on the last segment of their name the above code should work.
