Question

I’m not getting how to loop a ul and just add a class if li has class=’parent’

I always get each li with my new class…

this is the code

$('.navigation').find('li').each(function() {
        if($(this).hasClass('parent')) {
            $(this).find('li').each(function() {
                $(this).addClass("nivel_1");
                $(this).css('display', 'none');
                if($(".nivel_1").hasClass('parent')) {
                    $(".nivel_1").find('li').each(function() {
                        $(this).addClass("nivel_2");
                        $(this).css('display', 'none');
                    });
                }
            });
        }
    });

this is what i get

what should i do?

thanks!

So you have a tree view and those with a list within have a class called parent.

I haven’t tested this (and I don’t know if jQuery has something built in to do this) but you could try something like:

$(document).ready(function(){
    $('.navigation').find('li.parent > ul > li').addClass('nivel_X');
    $('.nivel_X').each(function(){
        var level = $(this).parents('.parent').size();
        $(this).removeClass('nivel_X').addClass('nivel_'+level);
    });
});

The idea is that you’ll add a class to each immediant child of a li with the “parent” class and then name that class nivel_X where X is replaced by the number of parents it finds above…

The following code works too and I like it better:

$('.navigation').find('li.parent > ul > li').addClass(function() {
    return 'nivel_'+$(this).parents('.parent').size();
});
