When encountering this error message...
An issue has arisen where the 'click' property cannot be read as it is undefined.
This problem suggests that the click() method cannot be executed because the WebElement has not fully loaded within the DOM Tree and remains in an undefined state.
Further Insights
Your statement about the "JavaScript working in console" indicates that the JavaScript functionality is fine. The actual issue lies in the WebElement not being fully rendered within the HTML DOM.
Possible Fix
To address this, it is recommended to utilize WebDriverWait for the
visibilityOfAllElementsLocatedBy()
method and select from the following Locator Strategies:
Using cssSelector:
new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.cssSelector(".button.button--new-resource")));
((JavascriptExecutor) driver).executeScript("var x= document.getElementsByClassName('button button--new-resource')[0];"+"x.click();");
Using xpath:
new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.xpath("//*[@class='button button--new-resource']")));
((JavascriptExecutor) driver).executeScript("var x= document.getElementsByClassName('button button--new-resource')[0];"+"x.click();");
Recommended Approach
In order to click on the element efficiently, it is suggested to apply WebDriverWait for the element_to_be_clickable() function and choose one of the below Locator Strategies:
Using CSS_SELECTOR:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.button.button--new-resource[href='/admin/certificate_types/new']>img[alt='Icon add user']"))).click()
Using XPATH:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='button button--new-resource' and @href='/admin/certificate_types/new']/img[@alt='Icon add user']"))).click()
Note: Ensure you import the following:
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
