Question

我在Firefox插件开发中遇到一个奇怪的事情：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();});
    });
}

当我使用Addon Builder编译它时，它会收到“Error: NS_ERROR_XPC_NOT_ENOUGH_ARGS: Not enough arguments [nsIDOMWindow.postMessage]”错误。然后我改变代码：

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();});
    });
}

我收到了另一个错误：TypeError: self.port is undefined。那么，怎么了？感谢。

将self更改为addon。详细文档为here。

Firefox插件：为什么面板内容中的self.port未定义？
