jquery referencing blank value in textarea
<p>I am trying to do a form validate which is checking for unfilled entries. In my form, I have inputs, textareas, and selects. I was able to get the input validation working, but I can't get the textarea to work (I haven't even tried on the select yet.). Here is my code:</p>

<pre><code>$(document).ready(function(){   
$('input[type=submit]').click(function()
{
    if( ($(":text:not(:disabled)[value='']").length !== 0) || $(textarea).html == '') 
    {
        //$('#message').parents('p').addClass('warning');
        var happy = "happy";
        document.getElementById("message").innerHTML = "All entries must be completed";
        //var cool = document.getElementById(id).attributes.getNamedItem("value").nodeValue;
        alert('All Entries Must Be Completed');
        return false;
    }
    else
    {
        alert ('mess up');
        return false;
    }

});                                     
</code></pre>

<p>});</p>

<p>How would I do this for select as well?
Also, I was only able to get this first part working from the help on another stackoverflow post, but I realized afterwords that I'm not sure why it works. Why am I doing the if statement for when its not equal to zero (!==) ? Shouldn't I be doing it when it's equal to zero?</p>
