如何使用 Addon SDK 从 main 向 page-worker 发送消息

Question

这是我的main.js

var background = require("sdk/page-worker").Page({
    contentScriptWhen:'start',
    contentScriptFile: ['./jquery.min.js','./socket.io1.js', './background.js'],
    onMessage: function(message) {
        console.log(message);
    }
});

和我的background.js

var myuser={}
//other socket.io stuff

如何从 main.js-> background.js 和 background.js->[=24 发送消息=] ?

(port ? postMessage ?): 任何可用样本 ?

Answer 1

main.js

// keep track of your active workers
var workers = [];

require("sdk/page-mod").PageMod({
    include: "*",
    contentScriptWhen:'start',
    contentScriptFile: ['./jquery.min.js','./socket.io1.js', './background.js'],
    onAttach: function(worker){

        workers.push(worker);

        worker.on("message", function(aData){
            //messages from background.js
        });

        //remove inactive workers
        worker.on("detach", function(){
            workers.splice(workers.indexOf(worker), 1);
        });

        //messages to background.js 
        worker.postMessage({
            johnny : "oh, hi mark", 
            mark   : "oh, hi johnny"
        });
    }
});

background.js

self.on("message", function(msg){
    //messages from main.js 
});

//messages to main.js   
function post(msg){
    self.postMessage(msg);
}
