Get error "ReferenceError: event is not defined"

Question

On project exists next js-function ``` function LoginKeyPressCheck() { $('#txtusername, #txtpassword').keypress(function (evt) { var charCode = (evt.which) ? evt.which : event.keyCode; // here get error $('#Errormsg').html(''); $('#Err_ValidateUser').html(''); if (charCode === 13) { evt.preventDefault(); $('#Err_ValidateUser').html(''); if ($.trim($('#txtusername').val()).length === 0) { $('#Err_ValidateUser').html('Validation Error: Value is required'); } else { loginProcess(); } } }); ``` When click button `TAB` get error "ReferenceError: event is not defined". Try to debug this function in FireBug but from line `var charCode = (evt.which)...` cursor moves in `else` block. I can't get where is problem. Thanks.

Accepted Answer

Change this line

```
var charCode = (evt.which) ? evt.which : evt.keyCode;
```

variable event was not defined, so you can not use it
