pitone selenio clicca elemento n-esimo

Question

di sotto è il codice ispezionato, quando il mouse viene hovererd sopra l'immagine, e fondamentalmente voglio l'immagine da essere cliccato ....

<ul id="product-list"> 

    <li class="product one-col new"> 
     <ul> 
      <li class="image" title="sample image"> 
       <a href="#product/1d77e790-f74a-3859-97db-c513cbece39c"> 
        <img width="" height="" alt="" src="/content/images/1.jpg"></img> 
        <span class="new"> … </span> 
        <span class="hover"></span> 
       </a> 
       <p class="retailer"> … </p> 
       <p class="brand"></p> 
      </li> 
      <li class="price"> … </li> 
      <li class="name" title="sample image"> … </li> 
      <li class="first-seen"> … </li> 
     </ul> 
    </li> 
    <li class="product one-col new"> … </li> 
    <li class="product one-col new"> … </li> 
    <li class="product one-col new"> … </li> 

sto usando python selenio e ho provato il sotto per cliccare il link span (hover)

browser.find_element_by_css_selector("ul#product-list > :first-child > ul > li.image > a > span.hover ").click 

tuttavia questo non funziona ... qualche idea?

aggiornamento:

browser.find_element_by_css_selector("ul#product-list > :first-child > ul > li.image > a > span.hover ").click()

aggiornamento:

questo non funziona troppo ...

browser.find_element_by_css_selector("ul#product-list > :first-child > ul > li.image > a ").click() 

aggiornamento:

actionchains anche provato, il mouse click..still senza fortuna ..

element = browser.find_element_by_css_selector("ul#product-list > :first-child > ul > li.image") 
    hov = ActionChains(browser).move_to_element(element) 
    hov.click() 

RISOLTO: finalmente questo ha funzionato ...

element_to_hover_over = driver.find_element_by_css_selector("ul#product-list > :first-child ") 
hover = ActionChains(driver).move_to_element(element_to_hover_over) 
hover.perform() 
if "" == driver.find_element_by_css_selector("span.hover").text: 
    driver.find_element_by_css_selector("span.hover").click() 

Answer 1

questo ha funzionato:

element_to_hover_over = driver.find_element_by_css_selector("ul#product-list > :first-child ") 
hover = ActionChains(driver).move_to_element(element_to_hover_over) 
hover.perform() 
if "" == driver.find_element_by_css_selector("span.hover").text: 
    driver.find_element_by_css_selector("span.hover").click() 

Answer 2

Il codice mancante (). Senza il metodo (), il metodo click non viene chiamato.

browser.find_element_by_css_selector("ul...span.hover ").click() 
#                ^^ 

---

element = browser.find_element_by_css_selector("ul#product-list > :first-child > ul > li.image > a > span.hover ") 
browser.execute_script("arguments[0].innerText = 'asdf';", element) 
element.click()
