如何在javascript html標籤內部刮取JavaScript函數的參數？

我想刪除Dygraph函數的參數（主要是日期的長行），因爲它們是圖上的點。直到現在，我還在使用findAll函數來抓取其他類型的標籤，然而，看起來我需要深入探究這個問題。如何在javascript html標籤內部刮取JavaScript函數的參數？

<script type="text/javascript">  
g = new Dygraph(

// containing div 
document.getElementById('DailySubscribers'), 
// CSV or path to a CSV file. 
"Date,Daily Subs\n" + "2016-07-31,1\n" + "2016-08-01,1\n" + "2016-08-02,0\n" + "2016-08-03,1\n" + "2016-08-04,0\n" + "2016-08-05,2\n" + "2016-08-06,10\n" + "2016-08-07,5\n" + "2016-08-08,1\n" + "2016-08-09,1\n" + "2016-08-10,2\n" + "2016-08-11,0\n" + "2016-08-12,0\n" + "2016-08-13,0\n" + "2016-08-14,0\n" + "2016-08-15,1\n" + "2016-08-16,1\n" + "2016-08-17,0\n" + "2016-08-18,0\n" + "2016-08-19,1\n" + "2016-08-20,0\n" + "2016-08-21,1\n" + "2016-08-22,0\n" + "2016-08-23,0\n" + "2016-08-24,7\n" + "2016-08-25,2\n" + "2016-08-26,0\n" + "2016-08-27,1\n" + "2016-08-28,1\n" + "2016-08-29,0\n" + "2016-08-30,0\n" + "2016-08-31,0\n" + "2016-09-01,0\n" + "2016-09-02,0\n" + "2016-09-03,0\n" + "2016-09-04,0\n" + "2016-09-05,1\n" + "2016-09-06,0\n" + "2016-09-07,0\n" + "2016-09-08,0\n", { 
     title: 'Daily Subs Gained for UCZx2vmIsQQLwzqwGWUbfqQA ', 
     legend: 'always', 
     ylabel: 'Daily Subs', 
     titleHeight: 20, 
     labelsDivStyles: { 
         'background': 'none', 
         'margin-top': '-10px', 
         'text-align': 'right', 
         }, 
     strokeWidth: 1, 
     colors: ["#dd2323", 
       "#dd2323", 
       "#dd2323", 
       "#dd2323"], 
     labelsKMB: true, 
     maxNumberWidth: 10 
     } 
); 
</script>

什麼是你想要的值。？ –

我想提取日期，日常子\ n「+」2016-07-31,1 \ n「+」2016-08-01,1 \ n「....這些值 –

因此，您想要提取該行直到'2016-09-08,0 \ n「，{'是否正確？ – chad

這裏是解決它（猜解，但工作）的快捷方式

bs = BeautifulSoup(data, 'html.parser') 
print(bs) 
values = (str(bs).split('"Date,Daily Subs\\n" +')[1].split(', {')[0].replace('\\n" + "', " ").replace('\\n', " ").replace("\"", "").split(" "))[1:-1] 
print(values)

輸出：
