Why i haven’t alert(1)?:(

This handler will be passed the incoming message as well as a function to send back the response.

You can probably write a glue component to hook this into an ajax enabled backend in not to many lines of code..

Is there an example or documentation I need to read to understand how I can convince easyXDM to do this JSON-RPC? IIUC I basically just need to write a lot of AJAX calls in the producer side, but it seems like a lot of boilerplate, and IIUC easyXDM already uses JSONRPC anyway.

But I have run into the same issue xiaohan2012 has mentioned. My function on the provider gets called correctly. But then if I want to change the DOM on the provider side (like simply change the innerHTML of a div tag, it won’t work with no errors I can see. But the same function does alerts correctly.

Here is the provider code:

var provider = new easyXDM.Rpc({}, {
local: {
updateCart: {
method: function(url, message, fn, fnError) {
var message = “This message is coming from ” + url;
testFunctionA(message);
//return message;
throw new Error(“something happened!”);
}
}
}
});

function testFunctionA(message) {
try {
document.getElementById(‘messageDiv’).innerHTML = message;
alert(message);
} catch(e) {
alert(e.message);
}
}

and the consumer code:

var consumer = new easyXDM.Rpc({
remote: “domainA_rpc.html”
}, {
remote: {
updateCart: {}
}
});

function updateCartOnRemote(message) {
consumer.updateCart(“domainB_rpc.html”, message, function() {
alert(‘Update was successful’);
}, function() {
alert(‘Update was not successful’);
}
);
}

My requirement is like this:

    The consumer passes the content as parameter and calls the function through RPC. 
    The provider receives the request and use the content to modify its page.

Here, *modifying its page* means trying to modify the DOM structure or the content in the DOM node.

The code for the **provider** side, which will modify its page content once requested by the consumer.

    var provider = new easyXDM.Rpc({}, {
        local: {
            modifyContent: {
                method: function(content){
                    // modify the content on my page
                }
            }
        }
    });

The **consumer** side, which will perform RPC to ask the provider to change its page.

        var consumer = new easyXDM.Rpc({
            remote: “remoteUrl”
        }, {
            remote: {
                modifyContent: {}
            }
        });
        //perform RPC and ask the provider to the modify its content
        consumer.modifyContent(“This is some content that should be used to modify your content”);

All things go on well excepts when the provider tries to use the content to modify its page.

No errors nor warnings are raised. But the page just won’t change as expected.

Besides, I run the “change content” code alone(like copy&paste&run in Firebug console or Chrome console), it will work.
