how to retrieve value from dynamic html form elements in servlet

Question

How can I retrieve value from input elements that are generated dynamically using servlet?

Here's an example:

<label>Name your </label><input type="text" name="values[]">
<input type="button" value="Add More" onClick="addXYZ();">

it can be retrieved using :

String val[]=request.getParameterValues("values[]");

now having problem in

 <form enctype="multipart/form-data" method="POST" action="uploadfr">
<input  type="file" name="filed[]" accept="image/*" required>
 <input type="submit" value="upload">
 </form>

I am assuming you are looking for something similar to:

<html>
<head>
<script type="text/javascript">
var addXYZ = function() {
    var retrievedValue = document.getElementsByName("values[]")[0].value;
    alert(retrievedValue);
}
</script>
</head>
<body>

<label>Name your </label><input type="text" name="values[]">
<input type="button" value="Add More" onClick="javascript:addXYZ()">
</body>
<html>
