How to click on a link with a Javascript executor in Selenium with python?

We can perform click operation on links with Javascript executors in Selenium. Javascript is a language used for scripting and runs on the client side (on the browser). Selenium gives default methods to work with Javascript.


javaScript = "document.getElementsByClassName('tp-logo')[0].click();"

There are couple of methods by which Javascript can be executed within browser −

  • Javascript execution at document root level.

    In this process, we shall identify the element with locators (class or id) and then perform the required action on it. Then execute_script() method is called and the Javascript is passed as a string to it.


javas = "document.getElementsByName('user-search')[0].click();"

Please note, we have used getElementsByName('user-search')[0]. The functions like getElementsByName and getElementsById return an array of matching elements. So for locating the first element, the index[0] is used. However if we are using getElementById function, we need not use the index since only one matching element is referred there.

Finally, for execution the web driver will put the Javascript statement in the browser and then perform the necessary action like clicking the required element. This Javascript does not mingle with the Javascript present in the webpage.

  • Javascript execution at element level.

    In this process, we shall identify the element with the help of web driver methods like find_element_by_xpath or find_element_by_id and so on. Then execute the necessary action on it like clicking the element. Finally, the method execute_script() is called. This method has the Javascript statement and the identified webelement as arguments.


userN= driver.find_element_by_id("user-search']")
driver.execute_script("arguments[0].click();", userN)


Code Implementation with Javascript executor for clicking links.

from selenium import webdriver
#browser exposes an executable file
#Through Selenium test we will invoke the executable file which will then #invoke #actual browser
driver = webdriver.Chrome(executable_path="C:\chromedriver.exe")
# to maximize the browser window
#get method to launch the URL
#to refresh the browser
# identifying the link with the help of Javascript executor
javaScript = "document.getElementsByClassName('tp-logo')[0].click();"
#to close the browser
