问题
I have a question that was somehow discussed here ([python][selenium] on-screen position of element) but that doesn't currently do what I'm trying to achieve.
My goal is the following: element.location gives the position of the top left corner of element in the browswer. I have a website in which, even if it's probably not a good selenium practice, I want to be able to click on such element purely based on its position because it has never changed and likely never will. Assuming element.location gives {'x': 253, 'y': 584}, this is the code I tried so far with no luck
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
driver.maximize_window()
url = "https://learn.letskodeit.com/p/practice"
driver.get(url)
open_window_elem = driver.find_element_by_id("openwindow")
# from wherever the mouse is, I move to the top left corner of the broswer
action = ActionChains(driver)
action.move_by_offset(-1000, -1000)
action.click()
action.perform()
y_coordinate = open_window_elem.location["y"]
x_coordinate = open_window_elem.location["x"]
action = ActionChains(driver)
action.move_by_offset(x_coordinate, y_coordinate)
action.click()
action.perform()
Nothing happens when I run this code. I would except to open a new window. Can somebody help?
回答1:
This is a solution that is based on the last answer available on (Clicking at coordinates without identifying element) that I had to adjust since it was not working on the website I posted in my original code:
# WORKING EXAMPLE 3
# assumptions is I know what coordinate I want to use
# in this example we use x = 253, y = 584
# remember: y = 584 -> it will move down (a negative value moves up)
zero_elem = driver.find_element_by_tag_name('body')
x_body_offset = zero_elem.location["x"]
y_body_offset = zero_elem.location["y"]
print("Body coordinates: {}, {}".format(x_body_offset, y_body_offset))
x = 253
y = 310
actions = ActionChains(driver)
actions.move_to_element_with_offset(driver.find_element_by_tag_name('body'), -x_body_offset, -y_body_offset).click()
actions.move_by_offset( x, y ).click().perform()
Basically, the body coordinates are not necessarily 0,0 that's why I had to use x_body_offset and y_body_offset.

It is better to click in the middle of the element than in its corner. Sometimes corners are not clickable. Coordinates x and y of "openwindow" element these are the coordinates of its upper left corner.
I suggest calculating the coordinates of the element's center. To do this, first check the width and height of the element:
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
driver.maximize_window()
url = "https://learn.letskodeit.com/p/practice"
driver.get(url)
open_window_elem = "//button[@id='openwindow']"
x = int(driver.find_element_by_xpath(open_window_elem).location['x'])
y = int(driver.find_element_by_xpath(open_window_elem).location['y'])
width = int(driver.find_element_by_xpath(open_window_elem).size['width'])
height = int(driver.find_element_by_xpath(open_window_elem).size['height'])
action = webdriver.common.action_chains.ActionChains(driver)
action.move_by_offset(x + width/2, y + height/2)
action.click()
action.perform()

Try this:
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
driver.maximize_window()
url = "https://learn.letskodeit.com/p/practice"
driver.get(url)
open_window_elem = driver.find_element_by_id("openwindow")
# from wherever the mouse is, I move to the top left corner of the broswer
action = ActionChains(driver)
action.move_by_offset(-1000, -1000)
action.click().perform()
y_coordinate = open_window_elem.location["y"]
x_coordinate = open_window_elem.location["x"]
action = ActionChains(driver)
action.move_by_offset(int(x_coordinate), int(y_coordinate))
action.click().perform()
