Detect the Enter key in a text input field

Question

I\'m trying to do a function if enter is pressed while on specific input.

What I\'m I doing wrong?

$(document).keyup(function (e) {
    if ($(\".inpu         


        

Answer 1

event.key === "Enter"

More recent and much cleaner: use event.key. No more arbitrary number codes!

NOTE: The old properties (.keyCode and .which) are Deprecated.

const node = document.getElementsByClassName("input")[0];
node.addEventListener("keyup", function(event) {
    if (event.key === "Enter") {
        // Do work
    }
});

Modern style, with lambda and destructuring

node.addEventListener('keyup', ({key}) => {
    if (key === "Enter") return false
})

If you must use jQuery:

$(document).keyup(function(event) {
    if ($(".input1").is(":focus") && event.key == "Enter") {
        // Do work
    }
});

Try this to detect the Enter key pressed in a textbox.

$(document).on("keypress", "input", function(e){
    if(e.which == 13){
        alert("Enter key pressed");
    }
});

It may be too late to answer this question. But the following code simply prevents the enter key. Just copy and paste should work.

        <script type="text/javascript"> 
        function stopRKey(evt) { 
          var evt = (evt) ? evt : ((event) ? event : null); 
          var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null); 
          if ((evt.keyCode == 13) && (node.type=="text"))  {return false;} 
        } 

        document.onkeypress = stopRKey; 

        </script>

 $(document).ready(function () {
        $(".input1").keyup(function (e) {
            if (e.keyCode == 13) {
                // Do something
            }
        });
    });
