hover() - trigger function changing the child of hovered object

in Using jQuery • 10 years ago

Hi there

I'm pretty new to jquery/javascript, and I can't answer this question for myself.

The thing I want is to change a class of an object (toggleClass) when hovering the parent-element.

Now; I can hover the parent, but then I want to apply the function to a child of it.

$('.parentclass').hover(
function () {
$(this.childclass).toggleClass('new-class-for-child');
},
function () {
}
);

of course this code does not work.

the 'this.childclass' of course does not select the right object.

Now I wanted to know how I select the child of the hovered parent correctly.

I tried things like

$(this).find('.childclass');

but unfortunately this did not work either. somehow I have to many brackets there I believe.

Well I think for some of you this is just peanuts, but right now I just can't figure it out.

Thanks for helping me out.

Cheers

Thanks a lot.

In the meantime I found the original problem;

.find does work too:

$(this).find('.childClass').toggleClass('newChildClass');

the problem was just, that I also wrote a point before the newChildClass - consequently like this

$(this).find('.childClass').toggleClass('.newChildClass');

And of course the .children does work as well. (but only for direct children?)

Anyway I got what I was looking for.

Thanks a lot for the fast and competent answer.

Cheers

You are welcome!

Here is another jsFiddle showing that children only selects direct child nodes and find is recursive.

.children vs. .find
