the KeyPressHandler is used for example for the SHIFT, CTRL, ALT keys. If you want to attach an event to another key you have to use KeyDownHandler. nameField.addKeyDownHandler(new KeyDownHandler() { @Override public void onKeyDown(KeyDownEvent event) { if (event.getNativeKeyCode() == KeyCodes.KEY_ENTER) { Window.alert(“hello”); } } });
$(“body”).keydown(function(e) { if(e.keyCode == 37) { // left $(“#showroom”).animate({ left: “-=980” }); } else if(e.keyCode == 39) { // right $(“#showroom”).animate({ left: “+=980” }); } });
Form approach As scoota269 says, you should use onSubmit instead, cause pressing enter on a textbox will most likey trigger a form submit (if inside a form) <form action=”#” onsubmit=”handle”> <input type=”text” name=”txt” /> </form> <script> function handle(e){ e.preventDefault(); // Otherwise the form will be submitted alert(“FORM WAS SUBMITTED”); } </script> Textbox approach If you … Read more
With plain Javascript, the simplest is: document.onkeypress = function (e) { e = e || window.event; // use e.keyCode }; But with this, you can only bind one handler for the event.

Also, if you plan on having a service run in the background, make sure to look at startForeground() and make sure to have an ongoing notification … Read more
I am working with React 0.14.7, use onKeyPress and event.key works well. handleKeyPress = (event) => { if(event.key === ‘Enter’){ console.log(‘enter press here! ‘) } } render: function(){ return( <div> <input type=”text” id=”one” onKeyPress={this.handleKeyPress} /> </div> ); }
In jQuery, the following would work: $(“#id_of_textbox”).keyup(function(event) { if (event.keyCode === 13) { $(“#id_of_button”).click(); } }); $(“#pw”).keyup(function(event) { if (event.keyCode === 13) { $(“#myButton”).click(); } }); $(“#myButton”).click(function() { alert(“Button code executed.”); }); <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> Username:<input id=”username” type=”text”><br> Password: <input id=”pw” type=”password”><br> <button id=”myButton”>Submit</button> Or in plain JavaScript, the following would work: document.getElementById(“id_of_textbox”) .addEventListener(“keyup”, function(event) { event.preventDefault(); … Read more
