jQuery: Insert 30 empty span tags
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.

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:
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.
$(document).ready(function() {
$('div').after( '<p class="slidesNav"></p>');
var spans;
for(var i=0;i<30;i++) {
spans += '<span></span>';
}
$('.slidesNav').append(spans);
});
