如何使用 Selenium 和 Python 单击启用 GWT 的元素

Question

I'm working with Selenium as a newbie and also as a newbie developer. I try to solve this XPath but with no results that is why I'm looking for help.

So I want to click in the checkbox which has a dynamic id but it is not that easy to find this checkbox based on tittle="Viewers"

Please notice there is a whole list of checkboxes with names on right from a checkbox in div which I want to include in my tests.

HTML:

<span class="row-selection"><input type="checkbox" value="on" id="gwt-uid-2215" tabindex="0"><label for="gwt-uid-2215"></label></span> <div class="row-label" title="Viewers">Viewers</div>

The desired element is a GWT enabled element so to click on the element you have to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following xpath based Locator Strategy :

• Using xpath based on title attribute:

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@title='Viewers']//preceding::span[1]//label"))).click()

• Using xpath based on innerHTML :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[text()='Viewers']//preceding::span[1]//label"))).click()

• 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
