title: How to redirect to other way on a select onChange event?
body: <p>I'm trying to make a product browser selection interface that when I click the selection of productType in the <code>column1</code>, the <code>column2</code> will appear the product with the selected productType by fetching information in the database (<code>SELECT productName from products WHERE productTYPE = 1</code>).</p>
  
  <p>I've done it with ajax, but it turns out ajax is not permitted in this assignment(really sad!)</p>
  
  <p>I can't come up with the solution without ajax. So Is there any way to make a post/get request with parameter and redirect to the self page(with self-post technique), only after I select a productType in the column1(onChange event on select element)</p>
