调用ng-click时如何从selenium python下载文件

Question

I am trying to emulate to download a file from a website using Selenium Python when clicking a button that is defined with ng-click.

The HTML file has this content:

<div class="col-lg-6 btn-group">
  <br/>
  <br/>
  <input type="button" ng-click="exportToExcel('#exportable')" class="btn-text btn-link export-main" value="Export" />
</div>

The code that I put after checking different options is not doing anything.

I

When I use the Selenium IDE, the only step recorded is to "click" on the "css=btn-text" element and that works, but with the chrome driver and Selenium in Python nothing is being downloaded.

I have this code to make sure that Chrome Driver downloads a file. (I have tested with other sites and this works)

 options = webdriver.ChromeOptions()
          prefs = {'download.default_directory' : self.download_location,
              'download.prompt_for_download': False,
              'download.directory_upgrade': True,
              'safebrowsing.enabled': False,
              'safebrowsing.disable_download_protection': False}
          options.add_argument('--headless')
          options.add_experimental_option('prefs', prefs)
          driver = webdriver.Chrome(chrome_options=options, 
                                   service_args=['--verbose', '--log-path=/tmp    /chromedriver.log'])

Here is the code that I am using to click on the button to download the file:

export_button = WebDriverWait(self.webdriver,10).until(ec.visibility_of_element_located((By.CLASS_NAME, "export-main"))) 

 ActionChains(self.webdriver)\
  .click(export_button)\
  .move_to_element(export_button)\
  .perform()

I would expect to download the excel file in the designated folder to the Chrome Driver, but it seems that Selenium and Angular don't play well together.

Is there other way to call the "ExportToExcel" function using Javascript?

Answer 1

not being able to test this myself, since every website is different, you might be able to call the javascript function you are asking about. Selenium allows you to execute javascript from within webdriver pretty easily. this can be done with

driver.execute_script("exportToExcel('#exportable');")

I don't know if this will download your file, but that answers your question of how you execute javascript within webdriver. again, whether or not this will download a file depends on many other circumstances that can't be determined from your post without having more information.

Answer 2

I got the answer to the problem:

just call the javascript to click on the "export button" like this:

self.webdriver.execute_script("arguments[0].click();", export_button)
