How to Use setTimeout in a for…loop

Question

What I want is this (news ticker type functionality):

1. Get a list of li\'s from a ul tag
2. Loop through all the li\'s and get the text
3. display t

Answer 1

The reason this is happening is because of closures. The for loop block has closures around it, so when you reference 'li_text' it was always equal the last value that li_text was set to. The for loop does not create a separate closure for each iteration through the loop.
