With jQuery you can traverse down the DOM tree to find descendants of an element. A descendant is a child, grandchild, great-grandchild, and so on.

Two useful jQuery methods for traversing down the DOM tree are:

The jQuery children() method returns all direct children of the selected element.

This method only traverses a single level down the DOM tree.

The following example returns all elements that are direct children of each <div> elements:

					 
        
          $(document).ready(function(){
            $("div").children();
          });

You can also use an optional parameter to filter the search for children.

The following example returns all <p> elements with the class name "first", that are direct children of <div>

					 
        
          $(document).ready(function(){
            $("div").children("p.first");
          });

The jQuery find() method returns descendant elements of the selected element, all the way down to the last descendant.

This method only traverses a single level down the DOM tree.

The following example returns all <span> elements elements that are descendants of <div>:

					 
        
          $(document).ready(function(){
            $("div").find("span");
          });

The following example returns all descendants of <div>:

					 
        
          $(document).ready(function(){
            $("div").find("*");
          });
