jQuery选择器

Question

I am making a jquery plugin.

You are given an object which contains several divs.

is there anyway to select the say, 3rd child div?

Answer 1

See .eq - remember it is 0 based

eg for the third div in an object containing a list of elements

$someObject.find('div:eq(2)')

Answer 2

.get（）从零开始的整数，指示要检索的元素。

($('div').get(3));

Answer 3

选择第三个div：

$('div').eq(2)

Answer 4

you can give them a className and use each or simple select the div, and count your selections

var n = 0    
$("div div").each(function() {
      n++;
      if(n == 3){
            $(this).html("do your thing");
      }
});
