在python中执行脚本

Question

我想在硒中执行这个脚本。

<div class="vbseo_liked"> 
<a href="http://www.jamiiforums.com/member.php?u=8355" rel="nofollow">Nyaralego</a> 
, 
<a href="http://www.jamiiforums.com/member.php?u=8870" rel="nofollow">Sikonge</a> 
, 
<a href="http://www.jamiiforums.com/member.php?u=8979" rel="nofollow">Ab-Titchaz</a> 
and 
<a onclick="return vbseoui.others_click(this)" href="http://www.jamiiforums.com/kenyan-news/225589-kenyan-and-tanzanian-surburbs.html#">11 others</a> 
like this. 
</div> 

这是我的代码来执行它。

browser.execute_script("document.getElement(By.xpath(\"//div[@class='vbseo_liked']/a[contains(@onclick, 'return vbseoui.others_click(this)')]\").click()") 

它没有工作。我究竟做错了什么？

Answer 1

找到硒元素，并把它传递给execute_script()点击：

link = browser.find_element_by_xpath('//div[@class="vbseo_liked"]/a[contains(@onclick, "return vbseoui.others_click(this)")]') 
browser.execute_script('arguments[0].click();', link)

因为我知道这个问题的背景下，这里是你如何解决它的一套东西：

• 点击 “11人” 通过JavaScript依托解决方案链接此处提供：How to simulate a click with JavaScript?

• 使custom expected condition等待元素文本不以“11个这样的其他人”结束。文本（这是你必须在Expected conditions with selenium该问题的解决方案）：

  class wait_for_text_not_to_end_with(object): 
      def __init__(self, locator, text): 
       self.locator = locator 
       self.text = text 
  
      def __call__(self, driver): 
       try : 
        element_text = EC._find_element(driver, self.locator).text.strip() 
        return not element_text.endswith(self.text) 
       except StaleElementReferenceException: 
        return False 
  

实现：

from selenium import webdriver 
from selenium.common.exceptions import StaleElementReferenceException 
from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 


class wait_for_text_not_to_end_with(object): 
    def __init__(self, locator, text): 
     self.locator = locator 
     self.text = text 

    def __call__(self, driver): 
     try : 
      element_text = EC._find_element(driver, self.locator).text.strip() 
      return not element_text.endswith(self.text) 
     except StaleElementReferenceException: 
      return False 


browser = webdriver.PhantomJS() 
browser.maximize_window() 
browser.get("http://www.jamiiforums.com/kenyan-news/225589-kenyan-and-tanzanian-surburbs.html") 

username = browser.find_element_by_id("navbar_username") 
password = browser.find_element_by_name("vb_login_password_hint") 

username.send_keys("MarioP") 
password.send_keys("codeswitching") 

browser.find_element_by_class_name("loginbutton").click() 

wait = WebDriverWait(browser, 30) 
wait.until(EC.visibility_of_element_located((By.XPATH, '//h2[contains(., "Redirecting")]'))) 
wait.until(EC.title_contains('Kenyan & Tanzanian')) 
wait.until(EC.visibility_of_element_located((By.ID, 'postlist'))) 

# click "11 others" link 
link = browser.find_element_by_xpath('//div[@class="vbseo_liked"]/a[contains(@onclick, "return vbseoui.others_click(this)")]') 
link.click() 
browser.execute_script(""" 
function eventFire(el, etype){ 
    if (el.fireEvent) { 
    el.fireEvent('on' + etype); 
    } else { 
    var evObj = document.createEvent('Events'); 
    evObj.initEvent(etype, true, false); 
    el.dispatchEvent(evObj); 
    } 
} 

eventFire(arguments[0], "click"); 
""", link) 

# wait for the "div" not to end with "11 others link this." 
wait.until(wait_for_text_not_to_end_with((By.CLASS_NAME, 'vbseo_liked'), "11 others like this.")) 

print 'success!!' 
browser.close()
