How do I return HTML from managed bean in JSF?
I have one method in my managed bean which returns javascript as a string. When the method is invoked from head
tag, it works fine. But when it is invoked from body
, the browser instead of rendering the javascript writes it as it is. What can be the problem?
In my JSF page when i do #{IndexBean.EastRegionGadgets}
in head
it works fine but it doesn't in body
. It outputs the HTML as it is. Here is the code:
package BusinessFacade;
import java.util.ArrayList;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.component.html.HtmlOutputText;
enum REGION{
NORTH,EAST,WEST;
}
class Gadget{
private String gadgetCode = "";
private REGION gadgetRegion = REGION.WEST;
public Gadget(String gadgetCode, REGION gadgetRegion){
this.gadgetCode = gadgetCode;
this.gadgetRegion = gadgetRegion;
}
public String getGadgetCode() {
return gadgetCode;
}
public void setGadgetCode(String gadgetCode) {
this.gadgetCode = gadgetCode;
}
public REGION getGadgetRegion() {
return gadgetRegion;
}
public void setGadgetRegion(REGION gadgetRegion) {
this.gadgetRegion = gadgetRegion;
}
}
@ManagedBean(name="IndexBean")
@RequestScoped
public class IndexBean {
ArrayList<Gadget> _list;
public IndexBean() {
}
@PostConstruct
public void initialize(){
_list = new ArrayList<Gadget>();
Gadget objGadget = new Gadget("<script type='text/javascript' src='http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js'></script><script>if (WIDGETBOX) WIDGETBOX.renderWidget('78d12c15-dc87-42f2-a78a-3f62a91a119a');</script><noscript>Get the <a href='http://www.widgetbox.com/widget/crystal-clock'>Crystal Clock</a> widget and many other <a href='http://www.widgetbox.com/'>great free widgets</a> at <a href='http://www.widgetbox.com'>Widgetbox</a>!

_list.add(objGadget);
objGadget = new Gadget("<script type='text/javascript' src='http://cdn.widgetserver.com/syndication/subscriber/InsertWidget.js'></script><script>if (WIDGETBOX) WIDGETBOX.renderWidget('1ccc3dee-8266-4b84-8191-13a4bf584d0c');</script><noscript>Get the <a href='http://www.widgetbox.com/widget/custom-clock'>Shiny Clock</a> widget and many other <a href='http://www.widgetbox.com/'>great free widgets</a> at <a href='http://www.widgetbox.com'>Widgetbox</a>!

_list.add(objGadget);
}
public String getWestRegionGadgets(){
HtmlOutputText objHtm开发者_开发百科lOutputText = new HtmlOutputText();
String strGadgets = "";
for(Gadget objGadget:_list ){
if(objGadget.getGadgetRegion() == REGION.WEST){
strGadgets += objGadget.getGadgetCode();
}
}
return strGadgets;
}
public String getEastRegionGadgets(){
String strGadgets = "";
for(Gadget objGadget:_list ){
if(objGadget.getGadgetRegion() == REGION.EAST){
strGadgets += objGadget.getGadgetCode();
}
}
return strGadgets;
}
}
In my JSF page when i do
#{IndexBean.EastRegionGadgets}
inhead
it works fine but it doesn't inbody
. It outputs the HTML as it is.
I suppose you're using <h:outputText>
in body
to output the HTML. As per the documentation it by default escapes HTML. You need to set its escape
attribute to false
.
<h:outputText value="#{bean.html}" escape="false" />
