I have a dynamic div create an image click or ipad tap.

HTML

<div></div> <div>
  $("#pgNum").live("click, tap", function () {
                var v = $("#book").turn("view");
                var rel = $("#pgNum").attr("rel");
                var spl = rel.split("x");// split the number from the text
                var pgClicked = parseFloat(spl[0]);// selects the number. Here I 
                //need to loop and number selected should = becomes pgClicked. 


                $("#book").turn("page", parseInt(pgClicked));
                $("#ContentTitle").fadeOut(1000);
                $("#CView").val(v[0] + " - " + v[1]);
            });

My c# code loads the a table of contents from the databases and put them into this:

HTML

</div> <div></div> <div>
<div id="contents" class="clscontents" rel="1 Front Cover">
<ul>
<li> <a href="#" id="pgNum" rel="1 Front Cover"></a>l</i>
<li> <a href="#" id="pgNum" rel="2 IFC"></a>l</i>
<li> <a href="#" id="pgNum" rel="3 Table of Contents"></a>l</i>
<li> <a href="#" id="pgNum" rel="6 Visual Index"></a>l</i>
<li> <a href="#" id="pgNum" rel="24 Layering Light"></a>l</i>
<li> <a href="#" id="pgNum" rel="28 Clearing Crystal"></a>l</i>
</ul>
</div>

What I need is when a user chooses a page to go like 28 Clearing Crystal goto page 28 or if 6 Visual Index goto page 6.With code below and above which is the same code it only goto page 1 no matter what page I click.

JavaScript

</div> <div>
  $("#pgNum").live("click, tap", function () {
                var v = $("#book").turn("view");
                var rel = $("#pgNum").attr("rel");
                var spl = rel.split("x");
                var pgClicked = parseFloat(spl[0]);
                $("#book").turn("page", parseInt(pgClicked));
                $("#ContentTitle").fadeOut(1000);
                $("#CView").val(v[0] + " - " + v[1]);
            });

somehow I need to loop and what was

JavaScript

selected = pgClicked

var spl = rel.split("x"); ?? Why?? this will always return array ["the same string",""] because in any attribute there is no "x"!

Why are you parsing first char of string (rel attribute) to Float and then to Int? How this make sense? Am I missing something?

All of your links have the same id

id="pgNum"

So

var rel = $("#pgNum");

will always return:

<a href="#" id="pgNum" rel="1 Front Cover"></a>

and

var rel = $("#pgNum").attr("rel");

will always return:

rel="1 Front Cover"

Your strange parsing code will because of that always return 1. See my comment.
Change your click event handler code to take attribute not from element with id #pgNum, but from element that was clicked:

JavaScript

 $("#pgNum").live("click, tap", function(e){
{...}
$(e.target).attr("rel");
{...}
});

How do I loop through attr("rel") to get the one I selected.
