        <form action="test.php" method="post">
University Name: <input type="text" name="college">
No. of branches:
<div id="dynamicInput">
          <select name="branches" id="branches" onchange="if (this.selectedIndex) addInput('dynamicInput');;" ">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="6">6</option>
  <option value="7">7</option>
  <option value="8">8</option>
</select>
     </div>   
<script>
    var counter = 0;
var limit = 3;  
function addInput(divName)
{    var counter = 0;   
    var k=parseInt(document.getElementById("branches").value);
    var newdiv;
       while(k>0) 
           {
        newdiv = document.createElement('div');
          newdiv.innerHTML = "Entry " + counter + " <br><input type='text' name='branch["+counter+"]'>";
          document.getElementById(divName).appendChild(newdiv);
          counter++;
          k--;
           }




}
    </script>
    <input type="submit" value="submit" />
        </form>
        </body>
</html>

并且php代码假设如下：

<?php
$name=$_POST["college"];
$text=$_POST["branch[0]"];
echo $name." ".$text"
?>

无法使用PHP访问java脚本生成的表单元素？
