我在 Firefox 插件开发中遇到了一件奇怪的事情：我编写这样的代码（我将注释代码从 Chrome 扩展转换为 Firefox 插件代码）：

function sendStoreIdentitiesMessage(identities, remember){
    console.log("Storing identities: "+identities.length);
    if(remember==null){
        remember=false;
    }
    //extension.sendMessage({type:"save.identities", identities:identities, remember:remember}, function(response) {
    //  identitiesNum=identities.length;
    //  identitiesDate=new Date();
    //  sendGetPageIdsMessage(function(){showCodeImageSuccess();});
    //});
    
    self.postMessage({type:"save.identities", identities:identities, remember:remember});
    self.port.on("response.save.identities",function(response){
        identitiesNum=identities.length;
        identitiesDate=new Date();
        sendGetPageIdsMessage(function(){showCodeImageSuccess();});
    });
}

当我用 Addon Builder 编译它时，它得到了错误：

“错误：NS_ERROR_XPC_NOT_ENOUGH_ARGS：没有足够的参数 [nsIDOMWindow.postMessage]”

然后我像这样更改代码：

function sendStoreIdentitiesMessage(identities, remember){
    console.log("Storing identities: "+identities.length);
    if(remember==null){
        remember=false;
    }
    //extension.sendMessage({type:"save.identities", identities:identities, remember:remember}, function(response) {
    //  identitiesNum=identities.length;
    //  identitiesDate=new Date();
    //  sendGetPageIdsMessage(function(){showCodeImageSuccess();});
    //});
    
    self.port.emit("message",{type:"save.identities", identities:identities, remember:remember});
    self.port.on("response.save.identities",function(response){
        identitiesNum=identities.length;
        identitiesDate=new Date();
        sendGetPageIdsMessage(function(){showCodeImageSuccess();});
    });
}

我得到另一个错误：

类型错误：self.port 未定义。

那么，怎么了？
