title: Let link deside what radio button is checked
body: <p>I have 3 links on a page, when clicking on one of the links, the radio button on the other page needs to be checked.</p>
  
  <p>Looks like this:</p>
  
  <pre><code>&lt;a href="page.html?amount=1"&gt;Go 1&lt;/a&gt;
  &lt;a href="page.html?amount=2"&gt;Go 2&lt;/a&gt;
  &lt;a href="page.html?amount=3"&gt;Go 3&lt;/a&gt;
  </code></pre>
  
  <p>I have some checkboxes on the page.html which needs to be checked.</p>
  
  <pre><code>&lt;input type="radio" name="amount" value="1" /&gt;
  &lt;input type="radio" name="amount" value="2" /&gt;
  &lt;input type="radio" name="amount" value="3" /&gt;
  </code></pre>
  
  <p>When click on Go 2, checkbox 2 needs to be checked.
  Anyone knows what js needs to be written?</p>
