With jQuery you can traverse up the DOM tree to find ancestors of an element. An ancestor is a parent, grandparent, great-grandparent, and so on.
Three useful jQuery methods for traversing up the DOM tree are:
The jQuery parent() method returns the direct parent element of the selected element.
This method only traverse a single level up the DOM tree.
The following example returns the direct parent element of each <span> elements:
$(document).ready(function(){
$("span").parent();
});
The jQuery parents() method returns all ancestor elements of the selected element, all the way up to the document's root element (<html>).
The following example returns all ancestors of all <span> elements:
$(document).ready(function(){
$("span").parents();
});
You can also use an optional parameter to filter the search for ancestors.
The following example returns all ancestors of all <span> elements that are <ul> elements:
$(document).ready(function(){
$("span").parents("ul");
});
The jQuery parentsUntil() returns all ancestor elements between two given arguments.
The following example returns all ancestor elements between a <span> and a <div> element:
$(document).ready(function(){
$("span").parentsUntil("div");
});
