Based on jquery documentation: First, you can define your selectors, it's the easier way if you already work with CSSs: http://docs.jquery.com/Selectors You can use something like: $('.error > ul > li').text(); to match all li's inside the element with class set to 'error' (the . referees a element using class name right after the dot). You can also use $('.error ul li').text() to get "each" li descending from a ul than from a element with a class named 'error'. In our .text() method this won't make much diference than using the first selector. Now let's try some jquery methods without complicating our basic selector: We have the .find() and .children() methods >From now I'm adapting the text from jquery documentation to our example: "In most cases two selections made with and without find() are equivalent, such as $('.error').find('li') and $('.error ul li'). However, using a selector filter may lead to unexpected results: $('.error').find('li:first').length may be > 1, (whereas $('.error li:first').length will never be > 1) as there is an implicit each() done within find()." In other words: you can try to select the first li of all div with the class attribute named 'error'. Now the .children(), this method will return all the immediate descendants elements within the selected element. Example: $('.error').children('ul').children('li') this will return exactly the directly children of the .error! .find() would return all descendants, not only the immediate ones. As said in the jquery documentation, it's important to refrain here: while .children() returns only the immediate descendants, .parents() will look at all ancestors. That's all, Have a good day. -- At, Leo Balter http://leobalter.net Blog técnico: http://blog.leobalter.net
