Require one field or the other but CANNOT be left blank
<p>I am looking for the following functionality:</p>

<p>The user is required to fill in either one of two fields to be able to submit. (e.g. There is a phone number field and an email field and the user must fill in at least 1 to leaves some sort of contact details.)</p>

<p>How can do I possibly do this through jquery? Forgive me as I am relatively new to jquery and am still learning.</p>

<p>
I was thinking along the lines of the validate function but any way to get my desired result would be nice. </p>
