Question

I am new to javascript; thus, it question may seem to be naive. I have a simple jQuery function as

$(document).ready(function(){
    $('#txtValue').keyup(function(){
        sendValue($(this).val());   

    }); 

});

This sends immediately when a letter is typed in

I explored jQuery events, but I was unable to find an event for ENTER. I want to run the function when I typed all letters and pressed ENTER.

Answer 1

Check the keyCode property of the event object. 13 represents the Enter key:

$('#txtValue').keyup(function(e){
    if(e.keyCode === 13) {
        sendValue($(this).val());   
    }
}); 

The keyup event will fire every time a key is released. There is no way to selectively fire the event, but you can choose when to handle it!

Edit

It’s actually better to use event.which, to deal with all browsers, as jQuery normalises the event object to help.
