Using jQuery, what is the best way to insert 30 empty span tags into a paragraph?  My code below works but I want to do it with less code.

<style type="text/css">
span {
display: block;
border: 1px solid red; margin: 5px; float: left; height: 5px; width: 5px; background: blue;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function() {
 $('p').append('<span />')

How could I do that inline like this:

$('div').after( '<p class="slidesNav">'+  _30_SPAN_TAGS_HERE '+'</p>');

Try this
<script>
$(document).ready(function() {

 for(var i=0;i<30;i++) $('#test').add('<p><span></span></p>').appendTo(document.body);

});
</script>
<div id="test"></div>

I would use a combination of the two solutions:

$(document).ready(function() {
    $('div').after( '<p class="slidesNav"></p>');

     var spans;
     for(var i=0;i<30;i++) {
          spans += '<span></span>';
     }

$('.slidesNav').append(spans);
});

This is more performant than using the append method 30 times. By doing so you would use the append method only once with a text variable which contains 30 span tags.
