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 inside the text box?
There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the Enter key to click this specific button if it is pressed from within this one text box, nothing else.
<input type="text" id="txtSearch" />
<input type="button" id="btnSearch" value="Search" onclick="doSomething();" />

- 5 Important note for rookies like me: The key part of this question is if you already have a form on the page so already have a submit button. The jQuery answer is cross browser compatible and a good solution. – Joshua Dance Commented Aug 18, 2014 at 17:38
- 6 @JoshuaDance, already having a form/submit is not a trouble. A page can have many forms (but not nested), each having their own submit. Every field of each form will trigger only the submit of that form. As stated by this answer. – Frédéric Commented Jan 14, 2016 at 11:19

Reset to default 1 2 Next 1554In 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();
if (event.keyCode === 13) {
document.getElementById("id_of_button").click();
}
});
document.getElementById("pw")
.addEventListener("keyup", function(event) {
event.preventDefault();
if (event.keyCode === 13) {
document.getElementById("myButton").click();
}
});
function buttonCode()
{
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" onclick="buttonCode()">Submit</button>
Then just code it in!
<input type = "text"
id = "txtSearch"
onkeydown = "if (event.keyCode == 13)
document.getElementById('btnSearch').click()"
/>
<input type = "button"
id = "btnSearch"
value = "Search"
onclick = "doSomething();"
/>
Figured this out:
<input type="text" id="txtSearch" onkeypress="return searchKeyPress(event);" />
<input type="button" id="btnSearch" Value="Search" onclick="doSomething();" />
<script>
function searchKeyPress(e)
{
// look for window.event in case event isn't passed in
e = e || window.event;
if (e.keyCode == 13)
{
document.getElementById('btnSearch').click();
return false;
}
return true;
}
</script>
Make the button a submit element, so it'll be automatic.
<input type = "submit"
id = "btnSearch"
value = "Search"
onclick = "return doSomething();"
/>
Note that you'll need a <form>
element containing the input fields to make this work (thanks Sergey Ilinsky).
It's not a good practice to redefine standard behaviour, the Enter key should always call the submit button on a form.
Since no one has used addEventListener
yet, here is my version. Given the elements:
<input type = "text" id = "txt" />
<input type = "button" id = "go" />
I would use the following:
var go = document.getElementById("go");
var txt = document.getElementById("txt");
txt.addEventListener("keypress", function(event) {
event.preventDefault();
if (event.keyCode == 13)
go.click();
});
This allows you to change the event type and action separately while keeping the HTML clean.
Note that it's probably worthwhile to make sure this is outside of a
<form>
because when I enclosed these elements in them pressing Enter submitted the form and reloaded the page. Took me a few blinks to discover.Addendum: Thanks to a comment by @ruffin, I've added the missing event handler and a
preventDefault
to allow this code to (presumably) work inside a form as well. (I will get around to testing this, at which point I will remove the bracketed content.)
In plain JavaScript,
if (document.layers) {
document.captureEvents(Event.KEYDOWN);
}
document.onkeydown = function (evt) {
var keyCode = evt ? (evt.which ? evt.which : evt.keyCode) : event.keyCode;
if (keyCode == 13) {
// For Enter.
// Your function here.
}
if (keyCode == 27) {
// For Escape.
// Your function here.
} else {
return true;
}
};
I noticed that the reply is given in jQuery only, so I thought of giving something in plain JavaScript as well.
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();
}
});

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();
}
}
Try it:
<input type="text" id="txtSearch"/>
<input type="button" id="btnSearch" Value="Search"/>
<script>
window.onload = function() {
document.getElementById('txtSearch').onkeypress = function searchKeyPress(event) {
if (event.keyCode == 13) {
document.getElementById('btnSearch').click();
}
};
document.getElementById('btnSearch').onclick =doSomething;
}
</script>
Short working pure JS
txtSearch.onkeydown= e => (e.key=="Enter") ? btnSearch.click() : 1
txtSearch.onkeydown= e => (e.key=="Enter") ? btnSearch.click() : 1
function doSomething() {
console.log('
