jQuery - Insert text and add string from variable

Question

I have the following jQuery:

j(".refreshMe").html(html);

var something = $("li", html).length;

if ( something > 0 ) {
    j('.showlatest').slideDown();
}

and HTML:

<p class="showlatest"></p>

What I want to happen is,

if ( something > 0 ) {
    j('.showlatest').slideDown();
    ADD THE CONTENTS OF 'something' WITH THE TEXT 'NEW MESSAGES'
}

E.g.

<p class="showlatest">2 new messages</p>

I suppose I could define the 'New Messages' text as:

var newmessages = "New Messages";

But how can I then, in PHP speak, echo the results?

What's wrong with using $('.showlatest').html(something + ' new message')? Note, you should be using id instead of class if these are single things. The selectors will be more efficient. — tster

I highly recommend that you change j to $ or $j. j will be used in nested for loops. — SLaks

Yes. Someone will write for (j = 0; j < something; j++). You should change that to var $j = jQuery.noConflict();. Unless you're already using a different $ library, you shouldn't do it at all. — SLaks

You can call the .text() method to set the text of an element, like this:

j('.showlatest').text(something + ' New Messages');
