How to get HTML element from PrimeFaces

In some scenarios, we might want to get the HTML element of a PrimeFaces component and process in javascript.
Assume we have a PrimeFaces inputText component like below.

<p:inputText id="address" value="#{myBean.address}" widgetVar="addrWV" />

1. widgetVar

addrWV.jq.get(0);

2. #{p:component('compId')}

document.getElementById('#{p:component("address")}');

Done!!
