I have a code. here I tried to read the selected value from select name = Teleph. but the result is null. Tell me how this can be implemented.

  • How do you read the value? - Mikhail Vaysman
  • @Mikhail "request.getParameter (" Teleph ")" - cccheshi
  • You need to add either a form or js code to your page. Pot here you can read in detail how to work with forms in servlets tutorialspoint.com/servlets/servlets-form-data.htm - Mikhail Vaysman
  • @MikhailVaysman I added, but it did not help me - cccheshi
  • @MikhailVaysman; As I understood, the form is used with input, but with the select form it is not necessary. in select, the value is obtained through the name of the select'a - cccheshi
