How can one avoid selecting 2 radio buttons with the same value?

问题

I have a form where I have two groups of radio buttons, names are different but values are shared, so I need to select a radio from the first group, once it's selected the radio from the second group and same value can not be selected, i. e. it becomes disabled...

<table>
<tr><th>Origin language</th><th>Target language</th></tr>
<tr><td>
<label><input type="radio" name="lang_or" value="de">German</label>
<label><input type="radio" name="lang_or" value="en">English</label>
<label><input type="radio" name="lang_or" value="ca">Catalan</label>
<label><input type="radio" name="lang_or" value="es">Spanish</label>
<label><input type="radio" name="lang_or" value="fr">French</label>
<label><input type="radio" name="lang_or" value="it">Italian</label>
<label><input type="radio" name="lang_or" value="pt">Portugues</label>
</td><td>
<label><input type="radio" name="lang_tg" value="de">German</label>
<label><input type="radio" name="lang_tg" value="en">English</label>
<label><input type="radio" name="lang_tg" value="ca">Catalan</label>
<label><input type="radio" name="lang_tg" value="es">Spanish</label>
<label><input type="radio" name="lang_tg" value="fr">French</label>
<label><input type="radio" name="lang_tg" value="it">Italian</label>
<label><input type="radio" name="lang_tg" value="pt">Portugues</label>
</td></tr>
</table>
