Question

I’m using struts2 and have this code that triggers after an action is performed (via Ajax):

    dojo.event.topic.subscribe("cambioProyecto", function() {
            var hola = json_entregables;
            alert("hola");
    }

The *json_entregables* variable is a parameter given via struts2. I can access it in the jsp, no problem. But i can’t in the script. What is the problem?

Answer 1

I figured out a way to gat what I wanted but it’s rather unclean. Since the anonymous function is a callback function from the Ajax process, I captured the response by defining a parameter for the function. That response is a string with the actual html of the response.

Now, to access the parameter, i have to include its value inside the jsp as a hidden element. Like this:

<s:hidden id="hidden_json_entregables" value="%{json_entregables}"/></p>

Then, i got it through jquery like this:

dojo.event.topic.subscribe("cambioProyecto", function(jsp) {
        var o = $(jsp)
        var string_entregables = o.find("#hidden_json_entregables").text();
}

Anyway, i don’t think it’s a good way to do it so i wouldn’t recommend it. But it worked for me. Thank for the support.
