Button click automation with JS?

• 0
  Hello!
  There is a site (not mine) where it was necessary to do autocomplete and auto-submit of the form. Wrote a custom script. Now, when you run the script, you can automatically fill in and submit the form.
  Today I went to DevTools in the Network section and saw this picture (attached to this question). Tell me what all these lines mean, I myself could not figure it out at all. It's about the labels in the timing tab.

  Here is additional information about each of the stages that you can see in the Timing tab:
  
  

  
  
  1. Queueing . The browser queues requests when:
     
     
     
     
     1. There are higher priority requests.
        
     
     
     2. There are already six TCP connections open for this source, which is the limit. Applies to HTTP / 1.0 and HTTP / 1.1 only.
        
     
     
     3. Browser briefly allocates disk cache space
     
     
     
  2. Stalled . The request may have been stopped for any of the reasons described in Queueing .
     
  
  
  3. DNS Lookup . The browser detects the IP address of the request.
     
  
  
  4. Initial connection . The browser establishes a connection including TCP handshake / retries and SSL negotiation.
     
  
  
  5. Proxy negotiation . The browser negotiates the request with the proxy.
     
  
  
  6. Request sent . The request is being sent.
     
  
  
  7. ServiceWorker Preparation . The browser starts the service worker.
     
  
  
  8. Request to ServiceWorker . The request is sent to the service worker.
     
  
  
  9. Waiting (TTFB) . The browser is waiting for the first byte of the response. TTFB stands for Time to First Byte. This time includes 1 round trip delay and the time taken by the server to prepare the response.
     
  
  
  10. Content Download . The browser receives a response.
      
  
  
  11. Receiving Push . The browser receives data for this response via HTTP / 2 Server Push.
      
  
  
  12. Reading Push . The browser reads the previously received local data.
      
  
  

  
  
  Source .
