lQuery: Select children by Index() including parent

Question

I want to dynamically get the index of all children with a certain attribute. I can do that like this

$("#parent [attribute]:eq(4)");

But sometimes the "#parent" itself also has the attribute, so I would like to get the index of that parent as well, relating to all the attribute elements index.

I tried this but for some reason it doesn't work

$("#parent").find("[attribute]:eq(4)").andSelf();

Answer 1

You can simply combine the selector with a comma , :

$("#parent [attribute]:eq(4), #parent[attribute]:eq(4)");

andSelf() method will only select #parent as a selector not #parent[attribute]:eq(4)

You can do this way too:

$("#parent [attribute]:eq(4)").add("#parent[attribute]:eq(4)");

Look thorough the api of add and andSelf method.
