How to get JSF id via jQuery

See a simple JSF example :

<h:form id="signup-form">
    <h:inputText id="email" value="#{}" />

It will generates following HTML code :

<input id="signup-form:email" type="text" />

Uses jQuery selector to get the email id, but failed.

   jQuery(document).ready(function($) {


This is a well-known problem to integrate JSF and jQuery – the colon “:” is reserved for jQuery selector. To use jQuery seletor to get the JSF id, you need to “escaped” the colon by placing two backslashes in front of it :

   jQuery(document).ready(function($) {

For PrimeFaces

PrimeFaces comes with a function to escape the JSF id :

   jQuery(document).ready(function($) {

This PrimeFaces.escapeClientId function is from primefaces.js, review the source code, it’s just a wrapper js function to replace the colon “:” with placing a double backslashes in front of it.


P.S Tested with PrimeFaces 3.3

    which ends up in HTML as

    so that you can get the id as:

    var elementId = $(‘.someClassName’);

      The JSF like so:
