jQuery | Traversing Descendants
Using jQuery we can traverse down the DOM tree in search of descendants of an element.
A descendant is a child, grandchild, great-grandchild and so on.
Traversing Down the DOM Tree: jQuery methods for traversing down the DOM tree are.
- children()
- find()
The children() method returns all direct children of selected element.
This method traverses only a single level down to DOM tree.
Example:
<!DOCTYPE html><html> <head> <style> .descendants * { display: block; border: 2px solid lightgrey; color: lightgrey; padding: 5px; margin: 15px; } </style> <script src= </script> <script> $(document).ready(function() { $("div").children().css({ "color": "green", "border": "2px solid blue" }); }); </script></head> <body> <div class="descendants" style="width:500px;"> current element <p>child <span> grandchild </span> </p> </div></body> </html> |
Output:
jQuery find() method returns descendant elements of the selected element and all the way down to last descendant.
Example-2:
<!DOCTYPE html><html> <head> <style> .descendants * { display: block; border: 2px solid lightgrey; color: lightgrey; padding: 5px; margin: 15px; } </style> <script src= </script> <script> $(document).ready(function() { $("div").find("span").css({ "color": "green", "border": "2px solid blue" }); }); </script></head> <body> <div class="descendants" style="width:500px;"> current element <p>child <span>grandchild</span> </p> </div> </body> </html> |
