.parent()
.parent( [selector] ) Returns: jQuery
Description: Get the parent of each element in the current set of matched elements, optionally filtered by a selector.
-
version added: 1.0.parent( [selector] )
selectorA string containing a selector expression to match elements against.
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.
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:
<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:
$('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.
