Question

I have a directory with several .html files.

Would like to read the list of files into a select list and when one is selected, display the file in a div.

Have no problem using jquery or whatever if that is what is required.

Answer 1

you should read directory with php, and populate select list, than onchange event of select you should read selected one and show it where you want.

just a simple example with iframe,

<?php
  $dir = ".";
  $dh = opendir($dir);
  echo "<select onchange='changePage(this)'>";
  while (($file = readdir($dh)) !== false) {
            echo "<option value='$file'>$file</option>";
  }
  closedir($dh);
  echo "</select>";
?>
<br />
<iframe id="f" src="" height="600" width="800" ></iframe>
<script type="text/javascript">
  function changePage(e) {
      var ifr = document.getElementById("f");
      ifr.src = e.value;
  }
</script>
