Phantomjs无法加载iframe [英] Phantomjs can't load iframe

问题描述

我是新手，最近开始使用phaperomjs和casperjs。我想从iframe获取信息，但是phantomjs无法加载它。

I'm a newbie, recently started to use phantomjs with casperjs. I want to get info from an iframe but phantomjs fails to load it.

这是我的脚本：

var casper = require('casper').create({
   verbose: true,
   logLevel: "debug",
   waitTimeout: 20000,
   retryTimeout: 100,
   viewportSize: {
     width: 1920,
     height: 1080
   },
   pageSettings: {
       "userAgent": 'Mozilla/5.0 (Windows NT 6.0) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.41 Safari/535.1'
   },
   localToRemoteUrlAccessEnabled: true
});

casper.start();

casper.open('http://www.badboysbarber.ru/online');

casper.waitForSelector('.y-main-container', function() {
   this.echo("Selector appeared.");
});

casper.then(function() {
   this.capture('screen.png');
});

casper.run();

因此，幻像会抛出错误（尽管选择器已正确定义）：

So, phantom throws an error (although selector is defined correctly):

[error] [phantom] Wait timeout of 20000ms expired, exiting.

有人可以帮帮我吗？也许我做错了什么？谢谢。

Could somebody help me please? Maybe I'm doing something wrong? Thank you.

推荐答案

iframe 将文档加载到另一个文档中。如果你想使用框架并使用CasperJS来获取数据，你可能需要 withFrame（） in Casper.prototype 。

An iframe loads a document inside another document. If you want to work with frames and use CasperJS to get data, you will probably need withFrame() in Casper.prototype.

以下脚本捕获主页中第一个 iframe 的原始HTML内容：

The following script captures the raw HTML content of the first iframe in your main page:

var casper = require('casper').create({
  viewportSize: {
    width: 1920,
    height: 1080
  },
  pageSettings: {
    'userAgent': 'Mozilla/5.0 (Windows NT 6.0) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/13.0.782.41 Safari/535.1'
  },
  localToRemoteUrlAccessEnabled: true
});

casper.start('http://www.badboysbarber.ru/online');

casper.withFrame(0, function () {
  this.echo(this.getHTML()); // HTML code of the first iframe
});

casper.run();
