DOM Manipulation

`$(id)`	Shortcut for `document.getElementById`: `var e = document.getElementById('mytextbox');` Use: `var e = PF.$('mytextbox'); var i = PF.$('myradiobutton');`
`$$(tagName, id,` `className, text)`	Shortcut for document.createElement. The `tagName` parameter must be specified. All other parameters are optional. `var div = PF.$$('div'); var divButton = PF.$$('div', 'button', 'button_class', 'this is a button');`
`remove(e, p) remove(id)`	Removes the element from the parent node.
`removeAll(el)`	Removes all child elements from the element. It recursively traverses all children and calls remove on them.

Example

This example demonstrates how to perform some simple DOM manipulations, including assigning an element to a variable and removing an element using the PF.Remove method.
