Compare text input's value against default value
<p>For a text input defined as:</p>

<pre><code>&lt;input type="text" name="Email0" id="Email0" value="1st Email" /&gt;&lt;br /&gt;
</code></pre>

<p>If the user changes the value of that text box I simply pass it along with the form submit...if they _haven't changed it - i need to pass a value of 'null'.</p>

<pre><code>$('#frmSignup').submit(function () {
    if (Email0.value != Email0.defaultValue) {
        alert("hit here"); //not hitting here
    }
});
</code></pre>

<p>You'll note that jQuery exists but i'm unclear as to exactly how to retrieve a input's defaultValue to jQuery.</p>

<p>thx</p>
