title: In JQuery how can I get the adjacent table cell?
body: <p>I have a table with multiple rows, and each row contains three cells. Each cell contains a textbox, so it looks like this:</p>
  
  <pre><code>XXXX   XXXX   XXXX
  </code></pre>
  
  <p>on the keyup event of the first textbox, I want its contents to be copied into the second textbox, but not the third textbox.</p>
  
  <p>my keyup event I can get a reference to the first textbox. Doing .parent() will give me the cell, and if I want, doing .parent() again will give me the row.</p>
  
  <p>What JQuery can I use to get the adjacent textbox?</p>
