How to use jQuery.serialize function with dynamic form elements

Question

How to serialize dynamic form inputs?

<table id="mytable">
<form id="myform">
 <tbody>
   <tr><td><input type="text" name="row0"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row1"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row2"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row3"></td></tr> <!-- dynamically generated -->
 </tbody>
 <tfoot>
   <tr><td><input type="button" id="save" value="SAVE"></td></tr> <!-- static -->
 </tfoot>
</form>
</table>

I want to use jQuery to load information from php

$('#save').click(function(){
   $.ajax({
     type: "POST",
     url: "post.php",
     data: $('#myform').serialize(),
     success: function(msg){
         console.log(msg);
     }
   });
});

This will not work if the lines are not dynamically generated, but I cannot figure out how to access or serialize dynamic content.

Serializing dynamic content works fine the way you do it (since you do it in a handler click, not a load) ... but you need to have a valid element <form>wrapped around <table>, for example:

<form id="myform">
<table id="mytable">
 <tbody>
   <tr><td><input type="text" name="row0"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row1"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row2"></td></tr> <!-- dynamically generated -->
   <tr><td><input type="text" name="row3"></td></tr> <!-- dynamically generated -->
 </tbody>
 <tfoot>
   <tr><td><input type="button" id="save" value="SAVE"></td></tr> <!-- static -->
 </tfoot>
</table>
</form>
