You can use the jQuery function Keypress

jQuery('#textbox').keypress(function(event){

	var keycode = (event.keyCode ? event.keyCode : event.which);
	if(keycode == '13'){
		alert('You pressed a "enter" key in textbox');
	}

});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputid="textbox" type="text" value="texto" />

Why has the "salt" option of password_hash been discontinued in PHP 7? Is there any alternative to PHP's mysql_connect command?

You can do this:

const inputEle = document.getElementById('enter');
inputEle.addEventListener('keyup', function(e){
  var key = e.which || e.keyCode;
  if (key == 13) { // codigo da tecla enter
    // colocas aqui a tua função a rodar
    alert('carregou enter o valor digitado foi: ' +this.value);
  }
});

<input id="enter" type="text" value="texto" />
