[ p, p.foo, p ]
.parent()
CHAPTER 2 ■ COMMON JQUERY ACTIONS AND METHODS
The .parent() method returns a set of the immediate parent elements of the current selection. For
instance, to select all parent elements of any elements with the class foo, use the following:
$(".foo").parent();
This returns the following:
>>> $(".foo").parent();
[ body, p#bar ]
To match only paragraph elements that are parents of elements with class foo, modify the code to
the following:
$(".foo").parent("p");
This narrows the result set:
>>> $(".foo").parent("p");
[ p#bar ]
.parents() and .parentsUntil()
Unlike .parent(), .parents() will return all parent elements, with an optional selector passed to filter
the results.
To select all parent elements of the check box in the form on the example page, use the following
code:
$(":checkbox").parents();
This finds every parent element, all the way out to the html element:
>>> $(":checkbox").parents();
[ label, fieldset, form #, body, html ]
To filter the results so that only the parent form element is returned, modify the code as follows:
$(":checkbox").parents("form");
This returns only the parent form element:
>>> $(":checkbox").parents("form");
