how read contents of dynamically added form elements???

please consider following steps improve markup structure. tough decode snippets in fiddle.

  1. each <input> element has different class, different attributes. , trying access them using common selector.
  2. your <a> links should have unique attribute or selector. both fired on click of 'add user'
  3. try use separate <div>s or atleast appropriate selectors accessing 2 different sets of <input> elements.
  4. none of <input> elements has same class. $('classname').serialize() never work elements.
  5. .attr('name') getting class? wrong logic; 'name' attributes each <input> not same.
  6. use delegation using .on(), in case of dynamically generated elements.
  7. keep common convention; either class selector or id's, don't mix them.

and here fiddle solution. made changes in html attributes, click events , everything.
