.parent()


.parent( [selector ] )Returns: jQuery

Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.

Given a jQuery object that represents a set of DOM elements, the .parent() method allows us to search through the parents of these elements in the DOM tree and construct a new jQuery object from the matching elements.

The .parents() and .parent() methods are similar, except that the latter only travels a single level up the DOM tree. Also, $( "html" ).parent() method returns a set containing document whereas $( "html" ).parents() returns an empty set.

The method optionally accepts a selector expression of the same type that we can pass to the $() function. If the selector is supplied, the elements will be filtered by testing whether they match it.

Consider a page with a basic nested list on it:

1
2
3
4
5
6
7
8
9
10
11
12

<ul class="level-1">
<li class="item-i">I</li>
<li class="item-ii">II
<ul class="level-2">
<li class="item-a">A</li>
<li class="item-b">B
<ul class="level-3">
<li class="item-1">1</li>
<li class="item-2">2</li>
<li class="item-3">3</li>
</ul>
</li>
<li class="item-c">C</li>
</ul>
</li>
<li class="item-iii">III</li>
</ul>

If we begin at item A, we can find its parents:

1
$( "li.item-a" ).parent().css( "background-color", "red" );

The result of this call is a red background for the level-2 list. Since we do not supply a selector expression, the parent element is unequivocally included as part of the object. If we had supplied one, the element would be tested for a match before it was included.

Examples:

Example: Shows the parent of each element as (parent > child). Check the View Source to see the raw html.
