The Python selenium chrome crawler seems to have been recognized. How else can it get around besides calling js?

here"s the thing. I was doing exercises on the food and drug safety website and found that there was such a situation on this website. As long as you use selenium to drive chrome to do any browser operation, you can"t get data

.

but after opening the website through selenium, there is no problem if you click manually.
after I also tried, I first filled in input data through selenium, and then manually clicked, but still prompted "the server did not return data". 

from selenium import webdriver
import time

browser = webdriver.Chrome()
url = "http://app1.sfda.gov.cn/datasearch/face3/base.jsp?tableId=89&tableName=TABLE89&title=%CA%B3%C6%B7%CC%ED%BC%D3%BC%C1%C9%FA%B2%FA%D0%ED%BF%C9%BB%F1%D6%A4%C6%F3%D2%B5&bcId=137403916083811026153735196207"  
browser.get(url)
browser.find_element_by_id("goInt").send_keys("4")
-sharp
time.sleep(5)
browser.find_element_by_xpath("//*[@id="content"]/div/table[4]/tbody/tr/td[7]/input").click()

I hope you can click.

Visualization is an anti-selenium method based on js, and you can't lose any browser.find_element.
for example: you call browser.find_element_by_id ("goInt"), and all subsequent requests return a value of 400.
the following is my personal understanding:
the find_element of selenium sends a request to the local server (chromediver, parses html and js) to get the data. I have seen the source code of selenium before and opened a service locally, which can be accessed directly through the URL.

provides another solution: 

from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtCore import QUrl
import time

app = QApplication([])
view = QWebEngineView()
view.load(QUrl("http://app1.sfda.gov.cn/datasearch/face3/base.jsp?tableId=89&tableName=TABLE89&title=%CA%B3%C6%B7%CC%ED%BC%D3%BC%C1%C9%FA%B2%FA%D0%ED%BF%C9%BB%F1%D6%A4%C6%F3%D2%B5&bcId=137403916083811026153735196207"))
view.show()
page = view.page()

def test():
    page.runJavaScript("document.getElementById('goInt').value = 5")
    page.runJavaScript("document.getElementById('goInt').parentNode.parentNode.childNodes[7].childNodes[0].click()")
    -sharptodo 

view.loadFinished.connect(test)
app.exec_()

have you solved the problem? I'm working on this website, too.
