display pages with multiple options selected in form

I have a form with drop down boxes. I want to display pages based on the selections from drop down. How to do this in javascript? Form is as below:

<form name="search">
<p>Quarter:
<select name="quarter">
<option value="Summer">Summer Quarter1 2008</option>
</select></p>
<p>Course:
<select name="course">
<option value="mba">MBA</option>
<option value="bba">BBA</option>
</select></p>
<p>Location:
<select name="loc">
<option value="loc1">Location 1</option>
<option value="loc2">Location 2</option>
<option value="loc3">Location 3</option>
</select></p>
<p><input type="submit" value="Search"></p>
</form>
