Trigger a button click with JavaScript on the Enter key in a text box

Question

I have one text input and one button (see below). How can I use JavaScript to trigger the button\'s click event when the Enter key is pressed ins

Answer 1

event.returnValue = false

Use it when handling the event or in the function your event handler calls.

It works in Internet Explorer and Opera at least.

Answer 2

This is a solution for all the YUI lovers out there:

Y.on('keydown', function() {
  if(event.keyCode == 13){
    Y.one("#id_of_button").simulate("click");
  }
}, '#id_of_textbox');

In this special case I did have better results using YUI for triggering DOM objects that have been injected with button functionality - but this is another story...

Answer 3

One basic trick you can use for this that I haven't seen fully mentioned. If you want to do an ajax action, or some other work on Enter but don't want to actually submit a form you can do this:

<form onsubmit="Search();" action="javascript:void(0);">
    <input type="text" id="searchCriteria" placeholder="Search Criteria"/>
    <input type="button" onclick="Search();" value="Search" id="searchBtn"/>
</form>

Setting action="javascript:void(0);" like this is a shortcut for preventing default behavior essentially. In this case a method is called whether you hit enter or click the button and an ajax call is made to load some data.

To trigger a search every time the enter key is pressed, use this:

$(document).keypress(function(event) {
    var keycode = (event.keyCode ? event.keyCode : event.which);
    if (keycode == '13') {
        $('#btnSearch').click();
    }
}

Answer 5

Use keypress and event.key === "Enter" with modern JS!

const textbox = document.getElementById("txtSearch");
textbox.addEventListener("keypress", function onEvent(event) {
    if (event.key === "Enter") {
        document.getElementById("btnSearch").click();
    }
});

Answer 6

I have developed custom javascript to achieve this feature by just adding class

Example: <button type="button" class="ctrl-p">Custom Print</button>
