title: jQuery selector on dynamic input value
body: <p>How can you use the <code>:contain()</code> on an input field, e.g.</p>
  
  <p><code>#inputfield</code> contains a dynamic value of 5.938 and I want to use <code>$("#inputfield:contains('5.938')")</code>.</p>
  
  <p>But that won't work, I've provided a demo at <a href="http://jsfiddle.net/NarutoDevil/ThFtt/" rel="nofollow">jsFiddle</a>. </p>
  
  <p>I don't want to use <code>if(element.val() == '5.938')</code> because I need a provisional selector instead doing an <code>if/else</code> statement.</p>
  
  <p>I also don't mean by using <code>[value=5.938]</code> because the value will change.</p>
