What's the best way to access a specific item in a list? and use it as a se开发者_JAVA技巧lector?
You can use .eq() or :eq() to get the jQuery object in a list:
$('ul li').eq(1).text();
//or:
$('ul :eq(1)').text();
You can try a demo here. When you get .get() you're getting a DOM element, which doesn't have any jQuery functions on it. Remember that both of these are 0-based so you'll need 1 to get the "Yes" in your example.
There are also other basic filters you may be interested in, for example :lt() (less-than-index), :gt() (greater-than-index), :first, :last and several others.
Use :eq filter selector:
$('ul li:eq(0)').text(); // gets first li
$('ul li:eq(1)').text(); // gets second li
$('ul li:eq(2)').text(); // gets third li
// and so on
