Just to understand this properly, the programm knows what this is when declared, but when you just say “li” instead it gets confused because there is no proper reference?[/quote]
That’s right. Using “li” means that it gets all LI elements on the page.
Sorry, it doesn’t work that way.
It gives you an array-like structure of all the matching HTML elements on the page.
The this keyword can easily become very confusing, so it can really help to assign it to a variable so that you know what is happening there.
For example:
function hideNext(){
var li = this;
$(li).prev().hide('fast', hideNext)
}
