Jquery Keyup with Contains to hide Span
<p>I am attempting to hide certain elements using the combination of keyup with contains. What I want to do is hide the span elements that do not equal my input values.</p>

<p>For instance, if I input the value 1 the spans containing the values 2 and 3 are hidden, leaving only the span containing the 1 visible. I would also want it to show all of the spans if I then deleted the 1 value from the input</p>

<p>Here is what I have so far, <a href="http://jsfiddle.net/8TXDM/36/" rel="nofollow">http://jsfiddle.net/8TXDM/36/</a></p>
