javascript - 注入(inject)的 Javascript 错误(Python Web Scraper)

Question

我之前遇到过类似的问题，但我不明白为什么它不让我点击复选框。我相信我通过错误的方式选择复选框来检查复选框时出错。

这是我的回溯:

Traceback (most recent call last):
  File "C:\Python27\Sample Programs\Spynner Basic.py", line 19, in <module>
    br.check('input[name="AdvSearchView$SRView$_resultGrid$ctl01$chk"]')
  File "C:\Python27\lib\site-packages\spynner\browser.py", line 846, in check
    self._runjs_on_jquery("check", jscode)
  File "C:\Python27\lib\site-packages\spynner\browser.py", line 394, in _runjs_on_jquery
    raise SpynnerJavascriptError("error on %s: %s" % (name, code))
SpynnerJavascriptError: error on check: jq('input[name="AdvSearchView$SRView$_resultGrid$ctl01$chk"]').attr('checked', true)

这是 HTML/CSS 部分:

<tr>
<td align="left" style="width: 100%; vertical-align: top; background-color: #ffffff; height: 100%">
<table id="AdvSearchView_SRView__resultGrid" cellspacing="0" border="0" style="border-width:0px;width:100%;border-collapse:collapse;" rules="cols">

</tr>

这是我的 Python 代码:

from __future__ import division
from __future__ import unicode_literals
from __future__ import print_function
import re
import spynner
from BeautifulSoup import BeautifulSoup
import time
br = spynner.Browser()
br.create_webview()
br.show()
br.set_html_parser("BeautifulSoup")
br.load("https://www.thomsononeim.com/s-log_in.asp")
br.fill("input[name=txtLoginID]", "username")
br.fill("input[name=txtPWD]", "password")
br.click("input[name=Submit]", wait_load=True)
br.click("input[name=Market]", wait_load=True)
br.select('option[value="IBESNA~US"]')
br.click("#MktGoImg", wait_load=True)
br.check('input[name="AdvSearchView$SRView$_resultGrid$ctl01$chk"]')
br.browse()
br.close()

我认为这与选择器上的名称错误有关。
