Unable to to move to next page in selenium-CodePudding

I am trying to loop through the pages and print the values for the table but it can't click the next button.

Error:

Selenium.common.exceptions.ElementClickInterceptedException: Message: 
Element <a class="page-link"
href="javascript:move('generic-tokenholders2?a=0xB8c77482e45F1F44dE1

Page: https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52#balances

My Code:

driver.get("https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52#balances")
wait = WebDriverWait(driver,30)
# num=driver.find_element(By.CSS_SELECTOR, "/html/body/div[2]/div[3]/div/div/ul/li[3]/span/strong[2]").getText()
for i in range(1,20):
    time.sleep(5)
    wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID,"tokeholdersiframe")))
    print("udj")
    simpleTable = driver.find_element(By.XPATH,"/html/body/div[2]/div[3]/table")
    rows = driver.find_elements(By.TAG_NAME,"tr")
    for i in range(1,len(rows)):
            cols = rows[i].find_elements(By.TAG_NAME,"td")
            for g in cols:
                    print(g.text)
    next = wait.until(EC.element_to_be_clickable((By.XPATH,"//div[@class='d-inline-block']//a[@aria-label='Next']")))
    driver.execute_script("arguments[0].scrollIntoView(true);",next)
    driver.execute_script("window.scrollBy(0,-200);")
    next.click()
    driver.switch_to.default_content()

Update: Error pmadhu: `

CodePudding user response：

If you observe in the loop you are switching to a iframe performing some actions and clicking on Next.

When the 2nd page opened the scope is still on the previous page iframe and you are trying to find an iframe within that. Which is not the correct workflow.

You need to perform switch_to.default_content() after clicking on Next and then try to do the same on each page.

Below code did click on the Next without any exception:

driver.get("https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52#balances")
wait = WebDriverWait(driver,30)

for i in range(5):
    time.sleep(5)
    wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID,"tokeholdersiframe")))
    next = wait.until(EC.element_to_be_clickable((By.XPATH,"//div[@class='d-inline-block']//a[@aria-label='Next']")))
    driver.execute_script("arguments[0].scrollIntoView(true);",next)
    driver.execute_script("window.scrollBy(0,-200);")
    next.click()
    driver.switch_to.default_content()
