回复了 ewwink 创建的主题 » python selenium-get(ctrl-u)等价的页面源代码

如果我没有错,你想比较原始的html ctrl+U 和呈现的html browser.page_source ,您可以使用 requests 

import requests

originalHTML = requests.get('http://...').text
print(originalHTML)

或者可以为 view-source: 

url = 'https://..../'
browser.get(url)
renderedHTML = browser.page_source

# open blank page because JS cannot open special URL like `view-source:`
browser.execute_script("window.open('about:blank', '_blank')")
# switch to tab 2
browser.switch_to_window(browser.window_handles[1])
browser.get("view-source:" + url)
originalHTML = originalHTML = browser.find_element_by_css_selector('body').text

# switch to tab 1
#browser.switch_to_window(browser.window_handles[0])

你可以试试这个 

....
var continue_spinning = true;

....
var stopSpinning = function() {
    if (continue_spinning) {
      setTimeout(stopSpinning, my_timer);
      return
    }
    ....

$('#gen').click(function() {
  if (continue_spinning) {
    continue_spinning = false;
    $('#gen').html('Start');
  }
  else {
    $('.reel-container:first').slotMachine(randGen());
    continue_spinning = true;
    $('#gen').html('Stop');
  }
});

演示: 

var reeling_time = 500;
var stop_spinning_time_difference = 350;
var start_spinning_time = 0;
var currency_symbol = "$";
var continue_spinning = true;

    number = (number + '');
    return number;
  }

  for (var $j = 0; $j <= 9; $j++) {
    hidden_reels_array[$j] = "";
    for (var $i = 0; $i <= 9; $i++) {
      hidden_reels_array[$j] += '<div class="reel-symbol' + ($i == 0 ? ' reel-loop' : '') + '">' + (($j + $i) % 10) + '</div>';
    }
  }
  var transformNumberToArrayPlusDollar = function(my_number) {
    var my_scale = parseInt(my_number, 10) > 999 ? 0 : 2;

    my_number = numberFormat(my_number, my_scale, ".", ",");

    var my_number_array = my_number.split('');

    // my_number_array.unshift(currency_symbol);

    return my_number_array;
  };

  //Effect for the reel to go up and then down like it is pushed to spin
  var effectBeforeSpin = function() {
    $parentSlot.find('.main-reel-symbol').removeClass('reel-stop').addClass('reel-begin');
  };

  var slotMachine = function(my_number) {

    var my_number_array = transformNumberToArrayPlusDollar(my_number);
    var reels_html = '';

    for (var $i = 0; $i < my_number_array.length; $i++) {
      reels_html += '<div class="reel">' + hidden_reels_array[($i % 10)] + '</div>';
    }
    effectBeforeSpin();
    var startSpinning = function() {
      $parentSlot.html(reels_html);
      var my_timer = reeling_time;
      $.each(my_number_array, function(my_index, my_value) {
        var next_value = /^[0-9]$/.test(my_value) ? (parseInt(my_value, 10) + 1) % 10 : "0";
        var stopSpinning = function() {

            setTimeout(stopSpinning, my_timer);
            return
          }
          $parentSlot.find('.reel:eq(' + my_index + ')').html("<div class='reel-symbol main-reel-symbol reel-stop'>" + my_value + "</div>")
            .append("<div class='reel-symbol'>" + next_value + "</div>");
        };


        setTimeout(stopSpinning, my_timer);

        my_timer += stop_spinning_time_difference;


      });

    };

    setTimeout(startSpinning, start_spinning_time);
  };

  slotMachine(my_number);

  return this;

};

HTML无效,已中断 BeautifulSoup 在这里修理 

....
html_doc = response.text.replace('<table <', '<')
html_doc = re.sub(r'<\!--\s+\d+\s+--\!>', '', html_doc)
html_doc = re.sub(r'</?font.*?>' ,'', html_doc)
soup = BeautifulSoup(html_doc, "html.parser")

trs=  soup.findAll('table')[8].findAll('tr')
print (len(trs))

注:使用 lxml 返回7而不是22
