It can become quite processor intensive using recursion to iterate through a large number of elements. Below is a javascript example which puts this technique into practice. All source files can be downloaded here. First we define a class which will be responsible for iterating through the document object model DOM and calling a method on each child node.

The method will be supplied as an argument and must define a html node as one of its own arguments. This allows us to define a method we would like to apply to all of our elements externally and independent of the class. Please click here to download the full source and an example.
