Adding iframe to JSF components

问题

Is it possible to add an iframe to a JSF component(RichFaces, PrimeFaces) from backing bean?

I need to embed externel webpages in my homepage. And user needs to set this url. I cannot use jQuery.

I am not able to find any iframe equivalent JSF component. Is there any particular reason for this?

回答1:

Just use plain HTML.

<iframe src="#{bean.iframeUrl}"></iframe>

The most probable reason why a component doesn't exist is because there would be no extra advantages to offer when wrapping it in a JSF component. For example <p>, <br>, <hr>, etc have also no JSF equivalent.

Yes possible. We can use plain HTML with in xhtml file. I have tried it. It is working good. below i have given my code.

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<f:view locale="#{facesContext.externalContext.requestLocale}">
<h:head>
    <title>
        <h:outputText value="your application title"></h:outputText>
    </title>
    <style type="text/css">
        #imagepgframe { 
            width: 100%;
            height: 100%;
            position: absolute;
        }
        #wrap { 
            width: 100%;
            position: absolute;
            top: 0px; 
            left: 0;
            bottom: 0;
            overflow-y: hidden;
            overflow-x: hidden;
        }
    </style>
</h:head>
<h:body>
    <h:form>
        <div id="wrap"> 
            <iframe id="imagepgframe" name="imagepgframe" frameborder="0" scrolling="auto" src="#{bean.iframeUrl}">
              <p>Your browser does not support iframes.</p>
            </iframe>
        </div>
    </h:form>
</h:body>

You can add iframe navegation with hsk:panelFrame, this a simple sample, when the case navegation is ok and the commponent has target attribute, this case navegation toViewId is show in the iframe (into panelFrame), and until iframe page navegation to a parentViewId, this iframe close and return to parent page
