The goal
I am working on a private project, written in Python3 and using Selenium to write information from a local database into input-elements on an HTML file of a website.
More explicitly : I want to write to a dnd-character-sheet-html on the website roll20 (https://roll20.org).
The Problem
Sadly, the "send_keys()" method of the selenium package often drops characters, due to a known bugg in the drivers for firefox and chrome that selenium uses. Thus I want to write using javascript directly. I managed to write to some elements, however, the second I click anywhere on the HTML all the entered values disappear.
Current Solution Attempts
Currently I identify the element I want to write to through its xpath and then set its "value" attribute. Below is some example code for this:
import selenium
class DemoClass:
def __init__(self, driver):
self.driver = driver
self.known_element_xpaths = ['Some/Xpath1', 'Some/Xpath2', 'Some/Xpath3']
def write_all_elements(self, input_string):
for element_xpath in self.known_element_xpaths:
self.write_to_element(element_xpath, input_string)
def write_to_element(self, element_xpath, input_string):
js_command = f'document.evaluate(\'{element_xpath}\', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.value = \'{input_string}\';'
self.driver.execute_script(js_command)
driver = selenium.webdriver.chrome()
page = DemoClass(driver)
page.write_all_elements('Test')
I do not know enough about javascript to understand why values keep disappearing. My last searches showed me that it might be about the form (?) being updated with its default values after clicking, leading to a reset of the HTML (?).
Either way, it seems to me I should've used a different way in javascript to write to these elements. What is the correct way to do it here?
Any help or pointing towards the right solution would be appreciated, I am a fair bit out of my depth here.
Attached Resources
In case it helps, here is also a screenshot of the section where I am trying to write to elements and a more close-up screenshot of the exact elements I'm trying to write to. Further here is an example HTML (including associated resources), but please note the text only disappears when writing to- and clicking on a character sheet online.
