PrimeFaces Ajax Navigation with Browser History/Hashtag

Solution

I have created a blog post explaining how to get this to work using jQuery BBQ, based on your question.

With jQuery BBQ you can keep track of state, history and allow bookmarking while dynamically modifying the page via AJAX and/or DHTML.. just click the links, use your browser's back and next buttons, reload the page..

First we should include jQuery BBQ.

<h:outputScript library="js" name="jquery.ba-bbq.min.js" />

Now consider we have the menu (with all our nav rules)

  <p:submenu label="Meat">
     <p:menuitem outcome="/meat/steak.xhtml" value="Steak" />
     <p:menuitem outcome="/meat/burger.xhtml" value="Burger" />
     <p:menuitem outcome="/meat/chicken.xhtml" value="Chicken" /> 
     <p:menuitem outcome="/meat/kebab.xhtml" value="Kebab" /> 
  </p:submenu>

Then the centered content

 <pe:layoutPane id="content" position="center">

     <h:panelGroup id="centerpanel" layout="block">
        <ui:include id="include" src="#{mainBean.currentNav}" />
     </h:panelGroup>

  </pe:layoutPane>

the include reflects the currentNav clicked.

now define a remoteCommand inside the form

<p:remoteCommand name="updateNav" 
                 actionListener="#{mainBean.updateNav()}"  
                 update=":centerpanel"/>

This remoteCommand will update our currentNav based on the hashtag.

Create your JS file or include the following code into the document ready

$(document).ready(function() {

   $('.ui-menuitem-link').click(function(event) {
       event.preventDefault();
       var currentNav = $(this).attr('href').
                        substr($(this).attr('href').indexOf("/faces") + 6)
       window.location.hash = '#' + currentNav;

   })

   $(window).bind('hashchange', function(e) {

    var url = $.param.fragment();
    updateNav([{name: 'currentNav', value: url}]); //remoteCommand Call

   })

   $(window).trigger('hashchange');

 });

Basically first we handle our clicks on the menu items, setting the hash of the window.

then we define an event of the hashchange of the window, using the help of jQuery BBQ.

ManagedBean

public void updateNav() {
    FacesContext context = FacesContext.getCurrentInstance();
    Map map = context.getExternalContext().getRequestParameterMap();
    currentNav = (String) map.get("currentNav");
}

For a complete code, please see my newly post created for the question.

And also the example is available on github.

Hope it helps.

Problem

I have implemented a web application which is a one-page-design. Which basically loads a single page then updates with AJAX the central content. The code is the following: ``` <h:body> <pe:layout id="page" fullPage="true"> <!-- West --> <pe:layoutPane id="west" position="west" > <f:facet name="header">Main Menu</f:facet> <h:form id="form1"> <p:panelMenu id="panelMenu"> <p:submenu label="Persons"> <p:menuitem value="Person List" update=":centerpanel" actionListener="#{layout.setAll('formPersonList.xhtml', 'Person List')}"> </p:menuitem> </p:submenu> </p:panelMenu> </h:form> </pe:layoutPane> <!-- Center --> <pe:layoutPane id="content" position="center"> <h:panelGroup id="centerpanel" layout="block"> <ui:include id="include" src="#{layout.navigation}" /> </h:panelGroup> </pe:layoutPane> </pe:layout> </h:body> ``` This basically works, but I want to enable browser navigation as well. For example like: http://ticketmonster-jdf.rhcloud.com/ with the hashtags on the url. So using the back/forward button I can go to the equivalent option. Any idea how to do this?
