title: Can a search engine follow <button> or <input> elements?
body: <p>I am considering replacing  links with  such as:</p>
  
  <pre><code>&lt;input type="button" onclick ="window.location.href('http://foo.com')" value="Click me!" /&gt;
  </code></pre>
  
  <p>There was a suggestion that search engines could not follow this kind of link. Does anyone have any knowledge to confirm this. </p>
  
  <p>thanks,</p>
