I want to trigger a button click when the Enter button is pressed in my page. I know how to do it if it's in a form. Like this
<form>
<input id="myInput" placeholder="Some text.." value="">
<input type="submit" id="myBtn" value="Submit">
</form>
<script>
var input = document.getElementById("myInput");
input.addEventListener("keyup", function(event) {
if (event.keyCode === 13) {
event.preventDefault();
document.getElementById("myBtn").click();
}
});
</script>
But how to trigger the button even when the Enter is pressed irrespective of where the focus is in the input element or not. just pressing the Enter button will trigger the button in the page. How can I do that?
You just need to add your event listener to the document instead of the input
document.addEventListener("keyup", function(event) {
if (event.keyCode === 13) {
event.preventDefault();
document.getElementById("myBtn").click();
}
});
You can use document
When use input.addEventListener then it will listen event from input only and when use document.addEventListener then it will listen from the entire page
var input = document.getElementById("myInput");
document.addEventListener("keyup", function(event) {
if (event.keyCode === 13) {
event.preventDefault();
document.getElementById("myBtn").click();
}
});
<form>
<input id="myInput" placeholder="Some text.." value="">
<input type="submit" id="myBtn" value="Submit">
</form>
you can bind the keyup event on window or document
window.addEventListener("keyup", function(event) {
if (event.keyCode === 13) {
event.preventDefault();
console.log("oops!")
}
});
Instead of binding the event listener to that input element, bind the listener globally like this
document.addEventListener("keyup", your_function_here);

I have this button that leads to a method in javascript that filters the information of a table:
<button type="button" id="search" title="Buscar" onclick="fn_cliente.filtraInformacion();"></button>
There are several fields for which you can filter the information, I want that when pressing "enter" on any input, it executes the same method as when clicking on the button
Use the following to bind the enter event to your search fields.
document.querySelectorAll('.searchfield').forEach(function(input) {
input.addEventListener('keypress', function(e) {
if (e.keyCode === 13) filtraInformacion();
});
});
Look at this code snippet
function filtraInformacion() {
console.log('filtraInformacion has been called!');
}
document.querySelectorAll('.searchfield').forEach(function(input) {
input.addEventListener('keypress', function(e) {
if (e.keyCode === 13) filtraInformacion();
});
});
<button type="button" id="search" title="Buscar" onclick="filtraInformacion();">Click me</button>
<br>
<input id='name' class='searchfield' placeholder='Press Enter!'>
<br>
<input id='lastname' class='searchfield' placeholder='Press Enter!'><br>
<input id='gender' class='searchfield' placeholder='Press Enter!'>
See? when the enter key is pressed, the function filtraInformacion is called.
This works. You can adapt it to whatever element you want.
<input type="text" id="account-location-country-input" class="mdc-text-field__input" required onkeyup = "if (event.keyCode == 13)document.getElementById('edit-account-button').click()">
I want to stop a user submitting a form upon clicking enter.
This works for that
$(document).ready(function() {
$(window).keydown(function(event){
if(event.keyCode == 13) {
event.preventDefault();
return false;
}
});
});
However I have other buttons on the page that when I tab to and click enter to avail of their functionality, this is blocked via this function.
The button sits as so:
<input type='button' tabindex="29" value='Add Additional Drug' id='addButton'>
And I only want to submit the form when enter pressed while my submit button is selected.
<input type="submit" name="submit" value="Submit" tabindex="40" class="submit"/>
How would I do this?
EDIT
I see the answer in the attached Stackoverflow but he allow people to press Enter if they have completed all the fields:
I don't want a user to press Enter unless they have a button selected(i.e. Can't press Enter, tab to button, can press enter, which will trigger the button to do its functionality and not submit the form.
The form works on a Tabbing basis, so a user will tab over all the fields.
Binding the keydown event to the whole document will affect all inputs and forms on the page, you may have several ones in your page so it will mess up the whole page logic.
You can bind it to a specific form instead:
$("#myForm input").not("#addButton").keydown(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
return false;
}
});
Demo:
$("#myForm input").not("#addButton").keydown(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
return false;
}
});
form input {
display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" id="myForm">
<input type="text" name="input1" />
<input type="text" name="input2" />
<input type="text" name="input3" />
<input type="submit" name="submit" value="Submit" tabindex="3" class="submit" />
</form>
Note:
I used #myForm as test id here to target a specific form in the
page, you just need to use your form id.
Using jQuery .not() method in .not("#addButton") won't affect the button with id="addButton".
First, keep in mind that what you are attempting breaks UI accessibility standards.
Bearing this in mind, you'll need to stop using a true "submit" button and use a regular button that impersonates the submit button.
Next, you'll need to manually trigger the click events for all non-submit button buttons via code.
Here's a working example. See the comments for details:
$(document).ready(function() {
$(window).on("keydown", function(event){
// Check to see if ENTER was pressed and the submit button was active or not
if(event.keyCode === 13 && event.target === document.getElementById("btnSubmit")) {
// It was, so submit the form
document.querySelector("form").submit();
} else if(event.keyCode === 13 && event.target !== document.getElementById("btnSubmit") ){
// ENTER was pressed, but not while the submit button was active
alert("Enter pressed on something other than submit button.");
// Cancel form's submit event
event.preventDefault();
// Invoke click event of target so that non-form submit behaviors will work
event.target.click();
// Tell JQuery to cancel the event
return false;
}
});
// Non-submit button event handling
$("#btnOther").on("click", function(){
alert("Other button clicked!");
});
// Set up your "regular" button to act as a "submit" button when it is clicked
$("#btnSubmit").on("click", function(){
// Submit the form
document.querySelector("form").submit();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action=# method=post>
<input name=test>
<input type=button id="btnOther" value="Other Button">
<input type=button id="btnSubmit" value=Submit>
</form>
I have a text field and a button. Either when the button is clicked or enter is hit, a function should be executed.
My approach works is intended. However, is it possible to combine those 2 functions (click and keypress), so that I only have 1?
$("button").click(function() {
getInput();
});
$("#name").keypress(function(e) {
if (e.which == 13) {
getInput();
}
});
function getInput() {
alert($("#name").val())
}
So I need to just append those events.
Here is a fiddle.
You can listen for multiple events using .on('listOfEvents')
Than you just need some additional rules to check when you need to run function.
$("button, #name").on('click keypress', function(e) {
if ($(e.currentTarget).attr('id') == 'submit' || e.which == 13) {
getInput();
}
});
function getInput() {
alert($("#name").val())
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="name" />
<button id="submit">
OK
</button>
function getInput(){
return $(".result").text($("input").val());
}
$("form").on("submit", (ev)=>{
ev.preventDefault();
// handle submission
getInput();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="">
<input type="text" />
<button>ok</button>
</form>
<div class="result"></div>
you can wrap your input and button in a form and listen for a submit event on that form. Forms can be submitted by pressing enter in an input inside of them or clicking a button that is enclosed
HTML
<form action="">
<input type="text" />
<button>ok</button>
</form>
Javascript
$("form").on("submit", (ev)=>{
ev.preventDefault();
// handle submission
getInput();
})
#eltonkamami answer is one idea and my idea is to provide same class for both input field and button like this :
(But, this will trigger whenever input field is changed)
$(".same").bind("click keypress", function() {
getInput();
});
function getInput() {
console.log($("#name").val())
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="name" class="same" />
<button id="submit" class="same">
OK
</button>
Hope it helps :)
We can differentiate a click and keypress by e.key or e.type parameters
Try this,
var getInput = function(e) {
if((e.which & e.which==13) || !e.key)
//e.key is a parameter for keypress event and not for click
alert($("#name").val())
}
$("button").click(getInput);
$("#name").keypress(getInput);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.1/jquery.min.js"></script>
<input type="text" id="name" class="same" />
<button id="submit" class="same">
Click
</button>
$("button,#name").on("click keypress",function(e) {
//alert($(e.currentTarget).html());
if (e.which == 13) {
getInput();
}else if(event.type == 'click'){
getInput();
}
});
function getInput() {
alert($("#name").val())
}
How can we make a form in a page doesn't submit on pressing Enter — rather. it does the same work as pressing a particular button or icon or image?
Here are the contents of my form:
<input type="text" id="txt" /><input type="button" value="search"
onclick="searchresult()" />
The problem is that if I press Enter, the form submits and text field clears itself but the function searchresult() doesn't show its effect. When only pressing the button, it works well.
HTML
<input type="text" id="txt"/>
<input type="button" value="search"/>
jQuery
$('input[type=text]').on('keyup', function(e) {
if(e.which == 13) { // 13 is keycode for enter
e.preventDefault();
}
})
You can also bind to submit() like following
$('form').submit(function(e) { // instead of only `form`,
// use with `id` or `class` combination
if(e.which == 13) {
e.preventDefault();
}
});
Remainder
Don't forget to place you code within
$(document).ready(function() {
// your code
});
in short
$(function() {
// your code
});
Alternatively, instead of disabling the enter key, you might be able to bind to the onsubmit event to perform any processing prior to submitting the form. From the MDN documentation:
The submit event is raised when the user clicks a submit button in a form ().
Try:
$('form').submit(function(event){
if(!$(':focus',this).is(':button'))
event.preventDefault();
});
This attaches to the form itself. If it was submitted any way other that clicking the submit button it halts the submission process. For better performance narrow down the 'form' selector.
Try this:
form
<form id="myForm">
<input type="text" id="txt" />
<input type="submit" value="search" />
</form>
js
<script>
$(document).ready(function(){
$("#myForm").submit(function(e){
e.preventDefault();
searchresult();
});
});
</script>

I have several <button> elements on a page, and I need to associate the <input> elements nearest them to those buttons. Right now, when you hit ENTER on any input field, it fires the first <button> in the form. How do I change this?
DOM:
<form action="irrelevant">
<div>
<select><option>1</option><option>2</option><option>3</option></select>
<input type='text'/>
<button>Hello</button>
</div>
<div>
<select><option>1</option><option>2</option><option>3</option></select>
<input type='text'/>
<button>Hello</button>
</div>
<div>
<select><option>1</option><option>2</option><option>3</option></select>
<input type='text'/>
<button>Hello</button>
</div>
<div>
<select><option>1</option><option>2</option><option>3</option></select>
<input type='text'/>
<button>Hello</button>
</div>
</form>
DOM Ready:
$('button').click( function(){
$(this).siblings().filter('select').val('3');
return false;
});
You need to use KeyPress event to catch "Enter" key pressed and then push the button you want using javascript.
For example:
//some key is pressed
$('input').keypress( function(event){
//is this "Enter"?
if (event.keyCode == '13') {
//finding the button inside the same <div> and clicking on it
$(this).parent().find('button').click();
//we don't need a default action
event.preventDefault();
}
});
something like this:
$('input').bind('keypress', function(e){
if(e.which == 13) { //Enter keycode
$(this).next().click()
}
return false;
});
