how to make enter key trigger input type button

[drooh]

Ok, I have a google store locator set up on my site. it uses an input type button to fire an onclick="searchLocations()"

the problem is that I need the enter key when pressed to also perform the searching

is there a way to make the enter key trigger the javascript function searchLocations() ?

something like
onclick,onEnterKey="searchLocations()"

<input onkeydown="if (event.keyCode == 13) document.getElementById('searchLocations').click()" type="text" id="addressInput" size="45" />

<input type="button" onclick="searchLocations()" id="searchLocations" value="Search For Store"/>
