can lxml/requests select dropdown options then par

问题:

I have a site I'm trying to test and although I can get a list of options in a dropdown I am not sure how select it? There is no submit button so if I select it then it will load an ajax table below.

I'm just not sure if lxml/requests can do this or how it could be done? I would appreciate it if anyone could confirm or knows the function that could do it ?

edit: My site is internal and not accessible but here is a sample site: https://www.tsx.com/listings/listing-with-us/listed-company-directory Notice if you select the box beside search it will pull out ajax results(A,B,C,etc..)

With lxml+requests setup, you operate on a different level, a lower level. There are no dropdowns for requests, it is not a browser.

The general approach to your problem is to:

• open Browser Developer Tools in your browser of choice, Network tab
• select an option in the dropdown
• observe the request(s) sent to the server in the Network tab
• simulate this/these requests in your Python code

There is one more "trick" that you can use to ease the developer tools to requests transition:

• right click on the request in the list of requests in Network tab
• click "Copy as cURL"
• go to http://curl.trillworks.com/ webpage and convert the cURL command to the Python+Requests code
