Jquery validation
<p>I am using the below code to validate a user's input:</p>

<pre><code>function validateAddress(){
//if it's NOT valid
if(f1.val().length = 0){
f1.addClass("error");
return false;
}
//if it's valid
else{
//whatever
}
</code></pre>

<p>My  question is: For the user to fill his address I have 3 text_fields. id=f1 - id=f2 - id=f3. In this line</p>

<pre><code>if(my_text_field_id.val().length = 0){
</code></pre>

<p>Can I check if any of these values (f1, f2, f3) are empty? (not just one at a time)</p>

<p>Thank you</p>
