通过一种或另一种技巧，我设法使用 SlimerJS 处理新窗口（window.open、target=blank 等）和 iframe 中的标题。也可以为新窗口更改导航器数据（例如 navigator.appVersion），但我坚持为 iframe 执行此操作。看起来 onInitialized 方法仅适用于主窗口和新窗口，但不适用于 iframe。

这是代码的一些部分。

var headers =
{ 
 "Accept-Language" : "test_language",
 "Accept" : "test/accpet",
 "Connection" : "keep-alive",
 "Keep-Alive" : "333",
 "Accept-Charset" : "test-utf",
 "User-Agent" : "test_ua"
}

var webpage = require('webpage').create(
{
 pageSettings:
 {
  javascriptEnabled: true,
  loadImages: true, 
  loadPlugins: true,
 }
});

_onPageCreated = function(childPage) 
{
 console.log('a new window is opened');
 childPage.settings.userAgent = options.useragent["navigator.userAgent"];
 childPage.customHeaders = headers;
 childPage.viewportSize = { width:400, height: 500 };

 childPage.onInitialized = _onInitialized;
 childPage.onNavigationRequested = _onNavigationRequested;
 childPage.onLoadStarted = _onLoadStarted;
 childPage.onLoadFinished = _onLoadFinished;
 childPage.onResourceRequested = _onResourceRequested;
 childPage.onPageCreated = _onPageCreated;
};

_onResourceRequested = function(requestData, networkRequest)
{
 for(var h in headers)
 {
  networkRequest.setHeader(h, headers[h], false);
 }
...
}

var _onInitialized = function() 
{
 this.customHeaders = headers;

 console.log("[webpage.onInitialized]");
 this.evaluate(function(options)
 {
  (function()
  { 
   window.navigator.__defineGetter__('appVersion', function ()
   {
    return options.useragent["navigator.appVersion"];
   });
   ...
  })();
 }, options);
};

...
               
webpage.onInitialized = _onInitialized;
webpage.onNavigationRequested = _onNavigationRequested;
webpage.onLoadFinished = _onLoadFinished;
webpage.onResourceRequested = _onResourceRequested;
webpage.onPageCreated = _onPageCreated;

我尝试使用 PhantomJS 执行此操作，但在以下情况下似乎无法使用“this”而不是“webpage”：

var _onInitialized = function() 
{
 console.log("[webpage.onInitialized]");
 this.evaluate(function()  // <<---not working
 {

 });
 console.log("test"); //is not being printed 
};

我希望此函数与“this”对象一起使用，以便可以将其定义为主页面和子页面的 onInitialized。

无论如何，主要问题是关于 SlimerJS 代码，而不是 Phantom 代码。
