Form - How to submit and go to url?

I have this form below which is perfect for my needs with dependent fields. What I would like to do is when someone selects one of the subcategories (ie: Beddings), they would then be transferred to a url (ex: www.beddings.com). But this is far beyond my understanding!

Any help would be appreciated!

Here is a demo of this form: http://www.tamilcodes.com/demopages/jsdropdownlist.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <script language="javascript" type="text/javascript">
function dropdownlist(listindex)
{

document.formname.subcategory.options.length = 0;
switch (listindex)
{

case "Home Ware" :
document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
document.formname.subcategory.options[1]=new Option("Air-Conditioners/Coolers","Air-                               Conditioners/Coolers");
document.formname.subcategory.options[2]=new Option("Audio/Video","Audio/Video");
document.formname.subcategory.options[3]=new Option("Beddings","Beddings");
document.formname.subcategory.options[4]=new Option("Camera","Camera");
document.formname.subcategory.options[5]=new Option("Cell Phones","Cell Phones");

break;

case "Education" :
document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
document.formname.subcategory.options[1]=new Option("Colleges","Colleges");
document.formname.subcategory.options[2]=new Option("Institutes","Institutes");
document.formname.subcategory.options[3]=new Option("Schools","Schools");
document.formname.subcategory.options[4]=new Option("Tuitions","Tuitions");
document.formname.subcategory.options[5]=new Option("Universities","Universities");

break;

case "Books" :
document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
document.formname.subcategory.options[1]=new Option("College Books","College Books");
document.formname.subcategory.options[2]=new Option("Engineering","Engineering");
document.formname.subcategory.options[3]=new Option("Magazines","Magazines");
document.formname.subcategory.options[4]=new Option("Medicine","Medicine");
document.formname.subcategory.options[5]=new Option("References","References");

break;

}
return true;
}
</script>

You can do it as follows using javascript

window.location = url

You need to check the subcategory and set the url accordingly.

Here you go

function redirect_subCategory() 
{
var e = document.getElementById("subcategory"); //set subcategory as id of select box
var subcategory = e.options[e.selectedIndex].value;

switch (subcategory)
{

case "Colleges" :
windows.location = "www.colleges.com";

break;

case "Institutes" :
windows.location = "www.insitutes.com";

break;

case "Schools" :
windows.location = "www.schools.com";

break;

case "Tuitions" :
windows.location = "www.tuitions.com";

break;

case "Universities" :
windows.location = "www.universities.com";

break;

}
}

Create a function and keep the above code inside it. On onchange event of the select box call the function as -

<select id="subcategory" onchange='redirect_subCategory()'>

Not sure if you're looking to actually POST to the form; if not, you can use your Option structure to store your target paths, create a function to navigate to urls, and call from the onChange event of your second dropdown ie:

<script language="javascript" type="text/javascript">
  function dropdownlist(listindex)
  {
    document.formname.subcategory.options.length = 0;
    switch (listindex)
    {
      case "Home Ware" :
        document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
        document.formname.subcategory.options[1]=new Option("Air-Conditioners/Coolers", "www.google.com");
        document.formname.subcategory.options[2]=new Option("Audio/Video", "www.yahoo.com");
        document.formname.subcategory.options[3]=new Option("Beddings", "www.ikea.com");
        document.formname.subcategory.options[4]=new Option("Camera", "www.apple.com");
        document.formname.subcategory.options[5]=new Option("Cell Phones", "www.sprint.com");
        break;
      case "Education" :
        document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
        document.formname.subcategory.options[1]=new Option("Colleges", "www.aol.com");
        document.formname.subcategory.options[2]=new Option("Institutes", "www.facebook.com");
        document.formname.subcategory.options[3]=new Option("Schools", "www.pintrest.com");
        document.formname.subcategory.options[4]=new Option("Tuitions", "www.lottopick.in");
        document.formname.subcategory.options[5]=new Option("Universities", "www.cnn.com");
        break;
      case "Books" :
        document.formname.subcategory.options[0]=new Option("Select Sub-Category","");
        document.formname.subcategory.options[1]=new Option("College Books","www.oracle.com");
        document.formname.subcategory.options[2]=new Option("Engineering","stackoverflow.com");
        document.formname.subcategory.options[3]=new Option("Magazines","monster.com");
        document.formname.subcategory.options[4]=new Option("Medicine","www.twitter.com");
        document.formname.subcategory.options[5]=new Option("References","www.yelp.com");
        break;
    }
    return true;
  }

  function navigate(target){
    window.location.href = 'http://' + target;
  }
</script>

Also:

    <tr>
      <td align="right" valign="middle">Sub Category : </td>
      <td align="left" valign="middle">
        <select name="subcategory" onchange="javascript:navigate(this.options[this.selectedIndex].value);">
          <option value="">Select Sub-Category</option>
        </select>
      </td>
    </tr>

You should write a java function for Select box's onChange event..

In that function, use window.location to redirect to a page..

Eg:

function redirect() {
      window.location = 'www.beddings.com';
}
