title: Set query string parameter as input value
body: <p>so with jQuery I'd like to take my url value example:</p>
  
  <pre><code>/finance-proposal?value=BD07UWT
  </code></pre>
  
  <p>And add it to this input element on my page:</p>
  
  <pre><code>&lt;input name="field[21]" id="field21" class="input-text required-entry " style="" value="" type="text"&gt;&lt;/input&gt;
  </code></pre>
  
  <p>I have tried to parse the url value however I have had no success.</p>
  
  <p>Any idea what would be the most simple method of doing this with jQuery when the page loads?</p>
  
  <p>Thanks, Nick</p>
