javascript - 无法在 Perl 脚本中使用 selenium 远程驱动程序从下拉列表中选择选项

Question

我在 perl 脚本中使用 Selenium::Remote::Driver 模块。我正在尝试从网页中的下拉列表中选择国家/地区，该国家/地区对于 Selenium 远程驱动程序不可见(显示为无)，我已经使用了很多方法，但仍然对我不起作用。您可以帮助我如何选择该国家/地区吗？从该下拉列表中。

use strict;
use warnings;
use Selenium::Remote::Driver;
use Selenium::Remote::WebElement;
use Time::HiRes qw(sleep);

my $driver = new Selenium::Remote::Driver
$driver ->get($url);

eval{$driver->find_element('register_address_country','id');};
      if($@)
      {
         print "register adress country element not found \n";
      }
      else
      {
       print "element is found \n";
       my $script = q{

            var elem1 = window.document.findElementById(register_address_country);
            return elem1;
            };

              my $elem2=$driver->execute_script($script,'DE'); 
              $elem2->click();
           }
  }

#here the script is exited without performing any operation even the element is find

我也在用这个:

$driver->find_element("//select[\@id='register_address_country']/option[\@value='DE']")->click();

#here  the element is find but not perform any operation like click or select

我也在用这个:

eval{$driver->find_elements('span','tag_name');};
      if($@)
      {
         print "span tag_name elements are not found \n";
      }
      else
      {
         print "span tag elements are found \n";
         my @values=$driver->find_elements('span','tag_name');
         foreach my $r(@values)
         {
             print "rvalue:$r \n";
             my $text1=$r->get_text();
             print "text1:$text1 \n";
             if($text1 eq 'Please choose your country')
             {
                $r->click();
                print "selected \n";
                last;
             }
         }

      }


#here please choose text is find but not clicked that webelement

Answer 1

我遇到了同样的问题，虽然没有解释这种情况是如何发生的，但我可以通过简单地添加另一次点击来解决这个问题。

所以你的例子看起来像这样:

print "span tag elements are found \n";
my @values=$driver->find_elements('span','tag_name');
foreach my $r(@values)
{
    print "rvalue:$r \n";
    my $text1=$r->get_text();
    print "text1:$text1 \n";
    if($text1 eq 'Please choose your country')
    {
       $r->click();
       $r->click();
       print "selected \n";
       last;
    }
}

尝试一下，它对我有用。
