selecting one row in dynamic table

selecting one row in dynamic table

Hey, i have a table where I need the elements of one row only.

Let's say I have a table where the rows are dynamically made by php:
  <tr>
  <td><input name="balance" type="text" /></td>
  <td><input name="interest_rate" type="text" /></td>
  <td><input name="term" type="text" /></td>
  <td><input name="payment" type="text" /></td>
  <td name="missing_type">1</td>
  <td>1</td>
  <td>1</td>
  <td>1</td>
  </tr>

This will repeat for however many there are in the array.

I want change the background of the 4 input cells if any of the 4 is still empty on change:

So far I have:
  $('#homeloan tr input').removeClass();
  $('#homeloan tr input[name]').addClass('red');


For now i just want to be able to change the background of the cells in one row, but the cells of the whole table changes. How can I change the cells in the row where the change occurred?
