按键无法使用我为某些聊天应用程序创建的功能

Question

I have some problem with key press when calling the key press in my function it does not work at all even I use multiple solution for it so I try to call a difference method key up or key down but it also not work

chat.connection.start().done(function () {
  var connectionname = prompt();
  chat.server.setConnectionName(connectionname);
  $("#myConnectionName").val(connectionname);
  $("inmessage").keypress(function (e) {
    if (e.which == 13) {
      var partnerId = $(this).closest('#chatBox').find('#partnerConnectionId').val();
      var message = $(this).val();
      chat.server.send(partnerId, message);
      $(this).val('');
    }
  });
)

It show no error method but it does not work also for other keydown.

Answer 1

As @briosheje mentioned in comments you need to use a class or id selector :

chat.connection.start().done(function () {
  var connectionname = prompt();
  chat.server.setConnectionName(connectionname);
  $("#myConnectionName").val(connectionname);
  $(".inmessage").keypress(function (e) {
    if (e.which == 13) {
      var partnerId = $(this).closest('#chatBox').find('#partnerConnectionId').val();
      var message = $(this).val();
      chat.server.send(partnerId, message);
      $(this).val('');
    }
  });
)

Answer 2

  var connectionname = prompt();
  chat.server.setConnectionName(connectionname);
  $("#myConnectionName").val(connectionname);

  $(".inmessage" **or** "#inmessage").keypress(function (e) {
    if (e.which == 13) {
      var partnerId = $(this).closest('#chatBox').find('#partnerConnectionId').val();
      var message = $(this).val();
      chat.server.send(partnerId, message);
      $(this).val('');
    }
  });
)
