Handles data response from JSF Ajax in Javascript -
i have follow managed bean class:
import javax.faces.bean.managedbean; import javax.faces.bean.sessionscoped; import java.io.serializable; @managedbean @sessionscoped public class hellobean implements serializable { private static final long serialversionuid = 1l; private string name; public string getname() { return name; } public void setname(string name) { this.name = name; } public string getsaywelcome(){ //check if null? if("".equals(name) || name ==null){ return ""; }else{ return "ajax message : welcome " + name; } } } and jsf file:
<?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"> <h:body> <h3>jsf 2.0 + ajax hello world example</h3> <h:form> <h:inputtext id="name" value="#{hellobean.name}"></h:inputtext> <h:commandbutton value="welcome me"> <f:ajax execute="name" onevent="example" render="output" /> </h:commandbutton> <h2><h:outputtext id="output" value="#{hellobean.saywelcome}" /></h2> </h:form> </h:body> and javascript function call when ajax response has been completed receive data parameter:
function ejemplo(data){ $('#tablaejemplo').append('<table><thead><tr><th>user</th></tr></thead>'+ '<tbody><tr><td>'+data.name+'</td></tr></tbody> </table>'); } my pretensions when ajax response success, print table username of manage bean inserted in input text don't know how access parameter (the data.name doesn't work) print, don't know if f:ajax returning or have set in place (i guess in manage bean...) format json data retrieve , can access in function, no?. ideas?
if want show name, why not adding ajax rendered part :
<h:commandbutton value="welcome me"> <f:ajax render="output" /> </h:commandbutton> <h2><h:outputtext id="output" value="#{hellobean.saywelcome} #{hellobean.name}" /></h2> if name null not show @ all.
