如何获取网络图的javascript标记中的数据，以便制作自己的图
How can I get the data inside a javascript tag for a web graph, so I can make my own graph?
到目前为止，使用python库twill和beautifulsoup，我能够登录到我的公用事业公司的网站，并分别访问包含我的天然气和电力使用数据的页面。实际上，他们用javascript绘制了一个很好的图，原始数据就埋在那里。
twill库非常好地显示了使用showforms()、show()等的web表单#1、#2、#3等的组成，但据我所知，还没有显示javascript元素beautifulsoup似乎能够显示html元素，比如网页的标题，例如：title1 = soup1.html.head.title，但我似乎无法让它列出javascript元素（页面上大约有4或5个不同的java脚本，其中一个包含以下数据）。
有没有办法分别在twill或beautifulsoup中使用类似showjavascript()或soup1.html.body.javascript的东西来访问这些javascript数据，并可能对其进行解析以导入matplotlib或者其他python绘图包？
javascript元素中的数据如下（您可以看到我、邻居和高效邻居）：

您可以使用slimit包解析javascript代码：
SlimIt是一个用Python编写的JavaScript迷你程序。它编译将JavaScript转换为更紧凑的代码，以便下载和运行更快。
SlimIt还提供了一个库，该库包括JavaScript解析器，lexer，漂亮的打印机和一个树访客。
在您的情况下，您可以通过找到对象的第一个赋值来应用它：
import json
from bs4 import BeautifulSoup
from slimit import ast
from slimit.parser import Parser
from slimit.visitors import nodevisitor
data = """
<script type="text/javascript">
(function() {
window.seriesDTO = {
...
};
})();
</script>
"""
soup = BeautifulSoup(data)
parser = Parser()
tree = parser.parse(soup.script.text)
json_data = next(node.right.to_ecma() for node in nodevisitor.visit(tree)
if isinstance(node, ast.Assign) and isinstance(node.right, ast.Object))
print json.loads(json_data)
打印Python字典：
