opening link in new window from cfgrid

Hi all, I am using the following code to create a link to a more info page for the selected row of data:

<cfinput type="button" name="MoreInfo" value="More Info" width="100" tooltip="Click here to view more information on the selected data" onClick="getURL('moreInfo.cfm?ID='+data.dataProvider[data.selectedIndex]['ID'])">

how can I make it open in a new window please?

many thanks
