Python + Selenium: How can click on "onclick" elements?

Question

I have an "onclick" element in a webpage whose HTML reads as follows:

<a href="#" onclick="fastener('3625')">Fastener</a>

I want to search this element using the string "fastener" or "Fastener" using Python + Selenium. The number "3625" will change depending on previous inputs, and hence cannot be searched for.

I tried the following, but in vain:

br.find_element_by_css_selector("a[@onlick*='fastener']").click()

Please suggest ways to do this. Thank you!

P.S.: I am using Python 2.7, with Chrome WebDriver and Chrome v62.

@onlick is an XPath syntax. In CSS you should use a[onlick*='fastener'] — Andersson

To search the element with text as Fastener you can use either of the following options :

Through Fastener :

br.find_element_by_link_text("Fastener").click()

Using onclick through fastener (xpath):

br.find_element_by_xpath("//a[contains(@onclick,'fastener')]").click()

Using onclick through fastener (css_selector):

br.find_element_by_css_selector("a[onclick^='fastener']").click()

Using capybara-py:

page.click_link("Fastener")

Capybara is designed to provide this and many other similar helper methods, such as one might need to write acceptance tests from the perspective of end users:

page.fill_in("Street", value="123 Main St")
page.select("United States", field="Country")
page.choose("Expedited shipping")
page.click_button("Place order")

Use contains to search element

//a[contains (@onclick='fastener')]

OR

   //a[contains(text(),"Fastener")]
