Can I override jQuery .val() for only some input elements?
<p>Suppose I'm using a "placeholder" jQuery plugin that reads the "placeholder" attribute from input elements and simulates it for browsers that don't yet support placeholders.</p>

<p>But I would still like $("input").val() to work properly -- that is, to return "" if the text in the textbox is the placeholder text.  Is there anyway I can override .val() just for these inputs?</p>
