Here's an example which automatically selects the first radio button.

javascript:

function autoForm()
{
    var myForm = document.forms["search"];

    myForm.elements["category"][0].checked = true;
}

window.onload = autoForm;

html:

<form name = "search">
<input type = "radio" name = "category"/>category 1
<input type = "radio" name = "category"/>category 2
</form>

Obviously, you'll have to implement the logic on which radio button is
to be selected.
