如何获取JavaScript生成的内容

Question

我目前在此（https://aca3.accela.com/MILARA/GeneralProperty/PropertyLookUp.aspx）网页上获取javascript生成的内容的HTML时遇到问题。它会在页面本身上生成javascript。我想知道自己在做什么错。我正在使用的代码是这样的：

import time
from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys
import selenium.webdriver.support.ui as ui
from bs4 import BeautifulSoup
driver = webdriver.Chrome(executable_path="/Users/MrPete/Downloads/chromedriver_win32/chromedriver")
driver.get('https://aca3.accela.com/MILARA/GeneralProperty/PropertyLookUp.aspx')

profession = Select(driver.find_element_by_xpath('//*[@id="ctl00_PlaceHolderMain_refLicenseeSearchForm_ddlLicenseType"]'))
profession.select_by_value("Pharmacist")
time.sleep(5) # Let the user actually see something!
lName = driver.find_element_by_xpath('//*[@id="ctl00_PlaceHolderMain_refLicenseeSearchForm_txtLastName"]')
lName.send_keys('roy')
search = driver.find_element_by_xpath('//*[@id="ctl00_PlaceHolderMain_btnNewSearch"]')
search.click()
time.sleep(5)
html = driver.execute_script("return document.getElementsByTagName('table')[38].innerHTML")
print(html)

现在，我没有输出，我得到的输出是：

<tbody><tr>
                                        <td style="white-space:nowrap;"><span class="ACA_SmLabel ACA_SmLabel_FontSize"> Showing 1-13 of 13 </span></td>
                                </tr>
                        </tbody>

[这是我要获取的表的标题。我想要的输出是整个表的HTML（张贴了由javascript生成的表的图片。我现在得到的是图片顶部的小标题，“显示1-13” 13'，而我想要的是整个桌子。

尝试更改

html = driver.execute_script("return document.getElementsByTagName('table')[38].innerHTML")
print(html)

收件人：

target = driver.find_element_by_xpath('//table[@class="ACA_GridView ACA_Grid_Caption"]')
print(target.text)

输出：

Showing 1-13 of 13
