如何在JavaScript HTML标签内刮擦JavaScript函数的参数

Question

我想删除dygraph函数的参数（主要是日期的长行），因为它们是图上的点。到目前为止，我正在刮擦其他类型的标签，这些标签通过使用Findall函数很容易获得，但是，我似乎需要更深入地研究这个问题。

<script type="text/javascript">     
g = new Dygraph(
// containing div
document.getElementById('DailySubscribers'),
// CSV or path to a CSV file.
"Date,Daily Subsn" + "2016-07-31,1n" + "2016-08-01,1n" + "2016-08-02,0n" + "2016-08-03,1n" + "2016-08-04,0n" + "2016-08-05,2n" + "2016-08-06,10n" + "2016-08-07,5n" + "2016-08-08,1n" + "2016-08-09,1n" + "2016-08-10,2n" + "2016-08-11,0n" + "2016-08-12,0n" + "2016-08-13,0n" + "2016-08-14,0n" + "2016-08-15,1n" + "2016-08-16,1n" + "2016-08-17,0n" + "2016-08-18,0n" + "2016-08-19,1n" + "2016-08-20,0n" + "2016-08-21,1n" + "2016-08-22,0n" + "2016-08-23,0n" + "2016-08-24,7n" + "2016-08-25,2n" + "2016-08-26,0n" + "2016-08-27,1n" + "2016-08-28,1n" + "2016-08-29,0n" + "2016-08-30,0n" + "2016-08-31,0n" + "2016-09-01,0n" + "2016-09-02,0n" + "2016-09-03,0n" + "2016-09-04,0n" + "2016-09-05,1n" + "2016-09-06,0n" + "2016-09-07,0n" + "2016-09-08,0n", {
        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>

Answer 1

这是解决它的快速方法（bruteforce但工作）

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)

输出：

<script type="text/javascript">g = new Dygraph(// containing divdocument.getElementById('DailySubscribers'),// CSV or path to a CSV file."Date,Daily Subsn" + "2016-07-31,1n" + "2016-08-01,1n" + "2016-08-02,0n" + "2016-08-03,1n" + "2016-08-04,0n" + "2016-08-05,2n" + "2016-08-06,10n" + "2016-08-07,5n" + "2016-08-08,1n" + "2016-08-09,1n" + "2016-08-10,2n" + "2016-08-11,0n" + "2016-08-12,0n" + "2016-08-13,0n" + "2016-08-14,0n" + "2016-08-15,1n" + "2016-08-16,1n" + "2016-08-17,0n" + "2016-08-18,0n" + "2016-08-19,1n" + "2016-08-20,0n" + "2016-08-21,1n" + "2016-08-22,0n" + "2016-08-23,0n" + "2016-08-24,7n" + "2016-08-25,2n" + "2016-08-26,0n" + "2016-08-27,1n" + "2016-08-28,1n" + "2016-08-29,0n" + "2016-08-30,0n" + "2016-08-31,0n" + "2016-09-01,0n" + "2016-09-02,0n" + "2016-09-03,0n" + "2016-09-04,0n" + "2016-09-05,1n" + "2016-09-06,0n" + "2016-09-07,0n" + "2016-09-08,0n", {        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>
