Question

I would like to get the third or forth element and set its id.

I found that:

$('#menu li:first').attr('id', 'test')

its actually working but I only get the first element. On the other hand I tried to use the following but it is not working.

$('#menu li').get(0).attr('id', 'test')

Can someone explain how to get the desirable element? (eg 4 or 5) and set its id and why the second bunch of code it’s not working?

Answer 1

you can use eq() method:

$('#menu li').eq(2).attr('id', 'third') // selects third element
$('#menu li').eq(3).attr('id', 'fourth') // selects fourth element
