Firefox 插件忽略 iframe

我正在尝试为 LinkedIn 构建一个插件，但内容脚本会在每一帧中输出......

我的 main.js：

exports.main = function() {

  var pageMod = require("page-mod");

  pageMod.PageMod({
    include: "http://www.linkedin.com/*",
    contentScriptWhen: 'ready',
    contentScript: 'alert("test")'
  });
};

通过检查框架元素，如果它是顶部框架，我可以执行操作

if(window.frameElement === null){ alert("YEAH this is the right place!); }

但是我的内容脚本很复杂并且使用了jquery，并且这个脚本仍然将脚本放在每一帧中......

更新，SDK page-modapi 现在支持“附加到”，因此您可以这样做：

var data = require("sdk/self").data;
var page = require('sdk/page-mod');

page.PageMod({
     match:['*'],
     contentScriptOptions: {},
     contentScriptFile: [data.url('myScript.js')],
     attachTo: 'top',
     onAttach: function(worker) {
         //set up hooks or other background behavior
     },
});

There are two approaches you could look into:

1. attach your content scripts using the tabs module. This works because the tabs module only deals with top-level documents. Here is a simple example:

2. do an initial load of a very small content script via page-mod, and then if thepage is something you really want to mod, inject scripts by sending them via port.emit messages. There is an example of this sort of scheme from the dotjs add-on:
