Selenium, select based on "onclick" value

Question

With Selenium, I'm trying to find the following checkbox on webpage.

<input type="checkbox" value="1" onclick="             document.getElementById('lastCheminClicked').value='123';             createInputsBinaireCell(25,'colonne5',1,0789,1,1,0,this.checked, this);">

The distinctive part is the '123' value in the "onclick", this is what selenium should look for.

Any way to find it on page? I have tried with xpath with no sucess.

Why not use a xpath with `contains`, that should do the trick, I tried it in chrome on a test-website and it found the right element. What was wrong with your xpath?`$x("//input[contains(@onclick, \"value='123'\")]")` — MushyPeas, Aug 08 '19 at 17:48

As you mentioned the partial value 123 is distinct within the onclick event so to locate the element you can use either of the following Locator Strategies:

Using CSS_SELECTOR:

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[type='checkbox'][onclick*='123']")))

Using XPATH:

element = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@type='checkbox' and contains(@onclick,'123')]")))

Note : You have to add the following imports :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

You might try finding all input tags, and then iterate through each looking at the onclick attribute. For example:

from selenium.webdriver.common.by import By

input_tags = driver.find_elements(By.TAG_NAME, 'input')
found_tag = None
for input_tag in input_tags:
    onclick_attribute = input_tag.get_attribute('onclick')
    if ".value='123'" in onclick_attribute:
        found_tag = input_tag
        break

You'll probably need exception handling around the get_attribute call.

XPath selectors allow using contains() function which can be used for partial match on the attribute or text value of the DOM element.

The relevant selector would be something like:

//input[contains(@onlclick, '123')]
