Python to click a button/link in JavaScript

Question

I want to show more page by click a button to run a JavaScript function as below:

<div class="loading" style="display:none;">
  <p class="btn blue"><span>さらに表示</span></p>
  <a href="javascript:void(0);" onclick="get_more();"></a>
</div>

I tried the code, it doesn't work, what can I do?

more_info_button = driver.find_element_by_tag_name('a').get('href=javascript:void(0);')
more_info_button.click()

Try using xpath //div/a[contains(@onclick,'get_more')]

If you want to click link that contains attribute @href equal to "javascript:void(0);", try

more_info_button = driver.find_element_by_xpath('//a[@href="javascript:void(0);"]')
more_info_button.click()

Same with CSS selector:

more_info_button = driver.find_element_by_css_selector('a[href="javascript:void(0);"]')

To locate link by text in preceding paragraph:

more_info_button = driver.find_element_by_xpath('//a[preceding-sibling::p[.="さらに表示"]]')

Update

Try below code to get extended topics list after clicking the button:

from selenium.webdriver.support.ui import WebDriverWait

topics_number = len(driver.find_elements_by_class_name('topics'))
more_info_button.click()
WebDriverWait(driver, 10).until(lambda driver: len(driver.find_elements_by_class_name('topics')) > topics_number)
extended_list = driver.find_elements_by_class_name('topics')

Thanks, How can I check if page is full loaded after click?

What exactly you want to do next after click?

mikezang Over a year ago

After click button, all rest contents will be extended to show in the same page, I want to parse it after page finishing loaded.

You might need to implement ExplicitWait to wait for new element to be present in DOM/to be visible...

I am not sure why I got the same result even f the button is clicked. I tried to parse this page https://weathernews.jp/s/topics/, the 'more' button is at the bottom of page, can you help me?
