Get cell table contents

Hi,

I'm looking to get the cell contents (only text) after I click on a row.

<tr onDblclick='newWindow()'><td>$asset_id</td>

If I double click on a row a new window opens as above....would it be possible to pass the contents of one of the cells into the new window so I can then read some from a database as one of the table cells holds the  primary key??

Thanks,
