CasperJS无法使用fill（）方法登录

我是Casper JS的新手，我遇到了使用fill()方法登录网站的问题。 在调试输出中，我登录后应该到达着陆页的url。然而，然后送我到一个空白页，并打破：CasperJS无法使用fill（）方法登录

[debug] [phantom] Navigation requested: url=about:blank, type=Other, lock=true, isMainFrame=false

我已经测试下面的代码登录到Facebook和它的工作。我还在下面的例子中使用Phantomjs版本的Casperjs代码成功登录了该网站。所以这个问题似乎特定于使用Casperjs fill（）方法登录。

1）下面是HTML（我把它匿名为安全起见）：

//login form 
<form id="***id_form***" class="loginBox" method="post" action="https://***login_link***/"> 
// input login 
<input id="IDToken1" type="text" value="" name="IDToken1"> 
// input password 
<input id="IDToken2" type="password" name="IDToken2">

2）这是我的Casperjs代码：

var start_url = 'https://***login_url***' 
casper.start(start_url, function() { 
    this.test.assertExists('form#***id_form***', 'form is found'); 
    this.fill('form#***id_form***', { 
     'IDToken1': '***MY_ID***', 
     'IDToken2': '***MY_PASSWORD***' 
    }, true); 
}); 
casper.run();

3）这里是控制台输出（我隐藏了网址）：

任何帮助表示赞赏。谢谢！

回答：

尝试以下操作：

casper.start(start_url, function() { 
    this.waitForSelector('form#***id_form***', function() { 
     this.fill('form#***id_form***', { 
      'IDToken1': '***MY_ID***', 
      'IDToken2': '***MY_PASSWORD***' 
     }, true); 
    } 
}); 
casper.then(function() { 
    ... 
}
