Click on button does not work

Question

I have a button made on ext, that he should open a window when Selenium clicked, but that doesn’t happen, I’m doing it this way.

    from selenium import webdriver
    from selenium.webdriver.support.ui import WebDriverWait
    import unittest

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.get("mywebsite")

    def ClickFunction(self):
            driver = self.driver
            driver.find_element_by_class_name(' x-form-file-input').click


    if __name__ == '__main__':
        unittest.main()

cmd does not return errors.

Ran 1 test in 5.580s

OK

where can I be missing? already tried by name, id.. none works

Answer 1

I believe the event:

driver.find_element_by_class_name(' x-form-file-input').click

Should be called that .click() and the method find_element_by_class_name search tags with attribute class and not name or id.

Using the method class_name

You should keep in mind that both Javascript and HTML as anything that understands the DOM attribute class="" works TOTALLY different from other attributes, search for class_name is different from normal attributes, the argument in the method find_element_by_class_name cannot contain spaces, it must be so:

driver.find_element_by_class_name('x-form-file-input')

It takes elements that contain the string between spaces, it will "catch" elements like:

<input class="x-form-file-input">
<input class="abc x-form-file-input">
<input class="x-form-file-input def">
<input class="abc x-form-file-input def">
<input class=" x-form-file-input "> (veja aqui tem espaço no começo e no fim e será pega também)
<input class=" x-form-file-input"> (veja aqui tem espaço no começo e será pega também)
<input class="x-form-file-input "> (veja aqui tem espaço no fim e será pega também)

Taking element by attribute name=""

If what you want is the attribute name="" thus:

<input name="x-form-file-input"></input>

You must do so:

  driver.find_element_by_name('x-form-file-input').click()

Picking up element by id=""

If what you want is the attribute id="" thus:

  <button id="x-form-file-input"></button>

You must do so:

  driver.find_element_by_id('x-form-file-input').click()

Taking element by a CSS selector

You can also use by CSS selector which is more advanced:

driver.find_element_by_css_selector("div.content .class")

Or take it by an ID:

driver.find_element_by_css_selector('#foo')

Opening the dialog window with send_keys

In browsers it is not allowed to use Click without the user, when you call .click he considers an Robothic action and blocks it, so instead, use the send_keys thus:

  driver.find_element_by_class_name('x-form-file-input').send_keys("/");

Or so:

driver.find_element_by_class_name('x-form-file-input').send_keys("C:");
