Question

JQuery selector problems when selecting using $(this)

Asked by: smacca

Hi,

I have the following html


              <ul class="jcarousel-controls">
              
                  <li><a class="first 1" href="javascript:void(0);">&lt;&lt;</a></li>
                  <li><a class="prev" href="javascript:void(0);">&lt; Prev</a></li>
                  <li><a class="next" href="javascript:void(0);">Next &gt;</a></li>
                  <li><a class="last" href="javascript:void(0);">&gt;&gt;</a></li>
              
              </ul>


I have several ".jcarousel-controls" and need to iterate through each as I must do some navigation from each element.

Now, I am using the following JQuery code, and simply want to addClass to the last <li> child - simple right!
But, it gets difficult for me when using the $(this) operator and I cannot find any information on how to concatenate statements etc.

The code I have is:


            $(".jcarousel-controls").each(function()
            {
                var obj = $(this).select(":last-child"); //this is returning the first child!!
                var len = 10; //code here usually finds out the number of photos listed above each "jcarousel-controls" and is why I must iterate using each statement.

                //add last selector to controls.
                //$(obj).addClass(len);

            });

This following code works:

            $(".jcarousel-controls").each(function()
            {
                var obj = $(this).children("li").children("a.last");
                var len = $(this).prev("div.jcarousel").children("ul").children("li").length;
                $(obj).addClass(len.toString());
            });


Can it be optimised??
