Do you know a pretty way to show/disable input by check one radio and one/several checkboxes with jQuery?

I get a lot of extra code, please give me link at least.

<input type="radio" name="first" value="1">
<input type="radio" name="first" value="2">
<input type="checkbox" name="second" value="1">
<input type="checkbox" name="second" value="2">
<input name="text">
