Add Another

Example: add_another.html | Add Another in JSFiddle

JavaScript:

• select the "div" we want to duplicate
• clone the "div" to create a new one
• change the id (to maintain uniqueness) of the new div
• insert the new div into the document

$(document).ready(function() {
    var numberofphones = 1;
    $('#addphone').click(function() {
      numberofphones++;
      newid = 'phone' + numberofphones;
      var phonediv = $('#phone1');
      var newphonediv = phonediv.clone();
      newphonediv.attr('id',newid);
      newphonediv.insertBefore('#addphone');
  });
 });
