How to automatically add form items with jQuery_jquery

The example in this article describes how jQuery automatically adds form items. Share it with everyone for your reference. The details are as follows:

Here you can dynamically add a form input by clicking a button

<script type="text/javascript" charset="utf-8">
 $(function() {
 var fieldCount = 1;
 $("#addFieldButton").click(function() {
  fieldCount++;
  if(fieldCount <= 5)
  {
  var fieldID = "recipient_email_" + fieldCount;
  $("#additionalEmails").append("<label for='"+fieldID+"'>Recipient Email "+fieldCount+": </label>"+ 
      "<input type='text' name='"+fieldID+"' " +
      "id='"+fieldID+"' size='30'><br />" );
  }
  else
  {
  alert("Maximum email fields reached.");
  }
 });
 });
</script>

I hope this article will be helpful to everyone’s jquery programming design.
