I have a parent with li's, and given the pointer to a li, I want to get it's position as a child.

For this I used:

```
li.index()

```

Now... I have one more condition, it should find an index only among these children that have display:block property in css.

I tried it some other ways around but I was unable to solve it.
Do have any ideas?

**Edit**: PS: or, rather for these that do not have display:none property.

**EDIT 2**: Well I these all require the reference to parent or specific ids, but what if have only a pointer to a li, for example:

```
<ul>
<li>Foo</li>
<li>Bar</li>
<li>Fiz</li>
<li>Buz</li>
</ul>

li=$('li:nth-child(n)');

```

now, let's suppose I know only one variable, and I want it's index among these that don't have css display: none propery...

**Solved** This is what did it:

```
li.add(li.siblings()).filter(':visible').index( li );

```

Thanks for helping me out with great ideas and different approach. :)
