如何使用 selenium 和 python 从网站获取工具提示文本，其中文本来自 javascript

Question

I am trying to get the tooltip text that shows when I hover over how long ago the game was played https://www.leagueofgraphs.com/summoner/eune/AnFrey99 ] 1

In the html code it doesn't shows the text and I figure it comes from a javascript and each rows has a script inside the tr tag, but so far I was not able to get the value of the var newTooltipData.

    var newTooltipData = {"match-2733966814": (new Date(1612964002882).toLocaleDateString() + " " + new Date(1612964002882).toLocaleTimeString()) + " - 31min 48s"};
    if (window.tooltipData) {
        window.tooltipData = Object.assign(window.tooltipData, newTooltipData);
    } else {
        window.tooltipData = newTooltipData;
    }

I want to get the exact date for each row along with other information that I already done. Here is my code and my tries.

 driver_second = webdriver.Firefox(executable_path=DRIVER_PATH) driver_second.get("https://www.leagueofgraphs.com/summoner/eune/"+'AnFrey99') time.sleep(5) accept_button=driver_second.find_element_by_xpath("/html/body/div[3]/div/div/div[3]/div[1]/button[2]") accept_button.click() tabel=driver_second.find_element_by_xpath("//table[@class='data_table relative recentGamesTable']") rows=tabel.find_elements_by_xpath("tbody/tr") for row in rows: elements=row.find_elements_by_xpath("td") if(len(elements)>1): script=row.find_element_by_xpath("script") data=elements[2].find_element_by_xpath("a/div[3]") data=script.get_property('innerHTML')

If you hover the div, JavaScript will append a new div to the website with the ID 'tooltip' (full source of the function here ):

var TooltipManager = (function () {
    [...]
            var tooltipElement = $('#tooltip');
            if (!tooltipElement.length) {
                $('body').append('<div id="tooltip"></div>'); #New Div appended
                [...]

Therefore Selenium can find this new div id = "tooltip" after you hover over the div, which calls this function.

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from selenium.webdriver.common.action_chains import ActionChains    
import time
    
driver_second = webdriver.Firefox(executable_path=DRIVER_PATH)
driver_second.get('https://www.leagueofgraphs.com/summoner/eune/AnFrey99')
time.sleep(3)

infos = driver_second.find_elements_by_class_name('gameDate')

for i in infos:
    hover = ActionChains(driver_second).move_to_element(i)
    hover.perform()
    time.sleep(1)
    DateofGame = driver_second.find_element_by_id('tooltip').text
    print(DateofGame)

output:

10.2.2021 14:02:55 - 20min 47s
