How to get the Enter key within a textbox to trigg

Question

I am trying to get the Enter key to trigger a function when it is pressed when inside a certain textbox, and not trigger the first or default button.

You can see an example of what is happening here: http://jsfiddle.net/cutsomeat/WZ6TM/1/

If you press other keys you will get an alert box with the keycode, yet if you press the Enter key you will not get the alert box with the keycode, but rather the alert box within the button click event.

Obviously the Enter key is trigger the button. Is there a way to avoid this and instead, capture the Enter key in the keyup event, then trigger another function?

Answer 1

Do e.preventDefault() in keyDown to avoid default action of button:

$('#myText').keydown(function(e) {
    if (e.keyCode == 13) {
        e.preventDefault();
    }
    alert(e.keyCode);
});

Answer 2

$(document).ready(function() {

    $('#myText').keypress(function(e) {
        if ( e.keyCode == 13 ) {  // detect the enter key
            $('#myButton').click(); // fire a sample click,  you can do anything
        }
    });

    $('#myButton').click(function(e) {
        alert('Button click activated!');
    });

});

DEMO

For live elements use .on() like below:

$(document).ready(function() {

    $(document).on('keypress', '#myText', function(e) {

        if ( e.keyCode == 13 ) {  // detect the enter key
            $('#myButton').click(); // fire a sample click,  you can do anything
        }
    });

    $(document).on('click', '#myButton', function(e) {
        alert('Button click activated!');
    });

});

Answer 3

Try this:

$('#myText').on("keypress", function(e) {
        if (e.keyCode == 13) {
            alert("Enter pressed");
            return false; // prevent the button click from happening
        }
});

Use .on() as .live() has been deprecated.

$(document).on("keypress", ".myText", function(e) {
     if (e.which == 13) {
         //do some stuff
     }
});
