Question

jQuery 1.7.1

Sometimes I have an element as an array,

<tr><td><input type="hidden" class="p" name="it" value="1"/></td></tr>
<tr><td><input type="hidden" class="p" name="it" value="2"/></td></tr>

The below jQuery code works,

$(".p").each(function(i){
alert($('.p')[i].value);
});

Sometime I have that element as a single element

<tr><td><input type="hidden" class="p" name="it" value="1"/></td></tr>

I want to make sure if the hidden input is an array or a single element before trying to execute the above jQuery code. How can I do that using jQuery?

Actually, that code works fine for both one input and two inputs.

But, use the size method to check:

if ($(".p").size() > 1) {
    $(".p").each(function(i){
        alert($(this).value);
    });
}
