如何使用硒单击此复选框

Question

I would like to select this checkbox using selenium

<input type="checkbox" name="rg" onchange="onCheckReg(this)" id="beauty_perfume_screening__c" value="beauty_perfume_screening__c" tabindex="-1" aria-labelledby="check-button-Beauty Perfume Screening check-group-header">

I tried finding by xpath an by id but always get the error unable to locate element

wd.find_element_by_id("beauty_perfume_screening__c").click()

Any Ideas?

Answer 1

Use xpath

driver.find_element_by_xpath("//input[@name='rg']").click()

and recommended is to use one of the wait methods -

WebDriverWait(driver, 10).until(
    EC.presence_of_element_located(By.XPATH, "//input[@name='rg']")

For selecting iframe -

root1 = driver.find_element_by_xpath("//iframe")
driver.switch_to.frame(root1)

Answer 2

To click on the element with text as save you can use either of the following Locator Strategies :

• Using id :

   wd.find_element_by_id("beauty_perfume_screening__c").click()

• Using css_selector :

   wd.find_element_by_css_selector("input#beauty_perfume_screening__c[name='rg'][value='beauty_perfume_screening__c']").click()

• Using xpath :

   wd.find_element_by_xpath("//input[@id='beauty_perfume_screening__c' and @name='rg'][@value='beauty_perfume_screening__c']").click()

Ideally, to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategies :

• Using ID :

   WebDriverWait(wd, 20).until(EC.element_to_be_clickable((By.ID, "beauty_perfume_screening__c"))).click()

• Using CSS_SELECTOR :

   WebDriverWait(wd, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#beauty_perfume_screening__c[name='rg'][value='beauty_perfume_screening__c']"))).click()

• Using XPATH :

   WebDriverWait(wd, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@id='beauty_perfume_screening__c' and @name='rg'][@value='beauty_perfume_screening__c']"))).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

Important : Incase the element is within an <iframe> you have to switch to the <iframe> first.
