title: How to fill a input field from a drop down list
body: <p>So this has been driving me nuts, im looking for a solution that will fill a input field from what ever selection is made from a drop down.</p>
  
  <p>My current working solution (that does not include a drop down) is as follows :</p>
  
  <pre><code>&lt;form method="link" action="dualstream/index.html"&gt;
  &lt;input value = 'apolloz' name="stream1" placeholder="" required="required"    
  autofocus="autofocus" /&gt;
  
  &lt;input type="submit" class="button" value="Click to watch the stream" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>So that auto fills the text field with "apolloz" then when you press submit it takes you to the relevant page which uses the word apolloz.</p>
  
  <p>Im looking for a solution that you can select the streamer from a drop down list, select it and that option fills the text field, and you can then submit.</p>
  
  <p>Im sure this is javascript based as i have seen similar things which use numerical values.</p>
  
  <p>Sorry if this is a bit vague, but any and all help is much appreciated. </p>
