title: Identifying a text_field with no unique property
body: <p>I have to fill in a mandatory text field and the html is as below</p>
  
  <p><code>&lt;input type="tel" id="54221" class="NEdit" title="" maxlength="5" style="position: absolute; overflow: hidden; font-style: normal; font-weight: normal; font-family: arial; font-size: 12px; text-align: right; width: 41px; left: 136px; top: 83px; height: 14px;"&gt;</code></p>
  
  <p>The <code>id</code> is dynamic and so I tried 
  <code>text_field(:trouble, :type  =&gt; 'tel', :max_length =&gt; '5')</code>
  and
  <code>text_field(:trouble, :type  =&gt; 'tel', :title =&gt; '')</code>
  and
  <code>text_field(:trouble, :type  =&gt; 'tel', :title =&gt; '', :max_length =&gt; '5')</code></p>
  
  <p>nothing seems to work. Any suggestions? Please do let me know. Thank you!</p>
