Re: RES: Ajax - obtaining a method result

[Musachy Barroso]

here is an example:

Action:
public GetIdAction {
  private int id;
  public String execute() {
     id = 10;
     return SUCESS;
  }

  public int getId() {
    return id;
  }
}

mapping:

<action name="hello" method="hello"
class="..package.action.SectionAction">
   <result type="freemarker">/view/Section/hello.ftl</result>
</action>



on the ftl file:
${id}

dojo.io.bind({
           url: "/hello.action",
           handler: function(type, data, e) {
             var id = data;
             alert(id);  // is "load" 
             
           },
           mimetype: "text/plain"
        });


Make sure the result is not decorated.

Hi ! 

Musachy ?

I'm getting the renderized view-result on my "divtest"..  when I expect
to get the "hello from action!!" string...

I'm not sure about my action mapping..

I'm trying to follow the examples but getting no success. :S


My action code:

  public String hello() {
    return "hello from action!!";
  }
-------------------------------------------------

My action map:

  <action name="hello" method="hello"
class="..package.action.SectionAction">
    <result type="freemarker">/view/Section/hello.ftl</result>
  </action>

-------------------------------------------------

Dojo code:

dojo.io.bind({
            url: "/hello.action",
            handler: function(type, data, e) {
              var id = data;
              //use your id
              alert(type);  // is "load" 
              document.getElementById('divtest').innerHTML = data;
            },
            mimetype: "text/plain"
         });
}

If you are making the call using the anchor or submit tag in the ajax 
theme, the returned text is available as a parameter(first parameter, 
when "type" is load) to the "notifyTopics", see:

 http://cwiki.apache.org/WW/ajax-tags.html

If you are going to use Dojo directly,:

dojo.io.bind({
            url: "/youraction",
            handler: function(type, data, e) {
              var id = data;
              //use your id
            },
            mimetype: "text/html"
         });

That's assuming you are going to return just the id in the response. You

can also returned a JSON string if you need to return more data. Or you 
can (but it will hurt :) ) return xml, which I wouldn't recommend unless

you have to. If you happen to be using GWT, you can just return the int 
from your method, and you will just get it back on your GWT(javascript) 
code. These are just a few ideas, there's got to be zillion ways of 
doing it these days.

Hi all

I want to make an ajax call to a method and get its returning.. (for 
use in a javascript fragment)


For example: I want to get the Id for the inserted person (in an ajax 
insert..)..


How it is possible?


This method could be in an action or directly in my Service class..



Thanks in advance

Luciano
