I am working on a project, which requires me to select a item from the categories navigation, which contains a “rel” attribute like (category-action, category-adventure, etc). As you can see from my demo: My Demo Script, it works on the first two categories, however, it does not work with the last two. Why is this? and how can I fix it?

Here is my current script:

$(document).ready(function()
{
    $("#sidebar ul li a").each(function()
    {
        var categories = $(this).attr("rel");
        var entries = $("#content-main .blog-entry").attr("rel").split(" ")

        $(this).hover(function()
        {
            for(i = 0; i < entries.length; i++)
            {
                if(entries[i] == categories)
                {
                    $("#content-main .blog-entry[rel~="+categories+"]").each(function()
                    {
                        $("#content-main .blog-entry[rel~="+categories+"]").addClass("match");
                    });
                }
            }
        },
        function()
        {
                $("#content-main .blog-entry[rel~="+categories+"]").each(function()
                {
                    $("#content-main .blog-entry[rel~="+categories+"]").removeClass("match");
                });
        });
    });
});

and here is my html file, if you don’t want to view the web page… although I’d strongly suggest viewing it.

    You could simplify all your javascript code to 

    $('#sidebar li a').hover(
    function(){
        $('div[rel*=' + $(this).attr('rel') +']' ).addClass('match');
        },
    function(){
        $('div[rel*=' + $(this).attr('rel') +']' ).removeClass('match');
    }
);

    and even simpler would be to use this.rel instead of the jquery equivalent $(this).attr('rel') as @lonesomeday commented..
