Reply to discussion (solution)

$ (Function () {$ (document ). keyup (function (event) {if (event. keyCode = 13) {alert ("1 ");}});});
This is better
$ (Function () {$ ("# loginform "). keyup (function (event) {if (event. keyCode = 13) {alert ("1 ");}});});

If your alert (1) pops up, the following code:

$ ("# Loginform"). submit ();
