javascript can access element without using getElementbyId ?

[Linwood Hayes]

I saw some sample code like below.  I thought we need to use getElementById or getElementsByName.  How can document directly access it like document.test... ?

<form name="test">
    <input type="text" name="month" value="may" />
    <input type="text" name="date" value="25" />
    <input type="text" name="hours" value="12" />
    <input type="text" name="minutes" value="30" />
</form>

...

document.test.month.value = "";
document.test.date.value = "";
