jQuery press button as enter on a text field - javascript

I have this text field:
<input id="address" type="text" value="">
and this button:
<input id="ricerca" type="button" class="enter" value="GO!">
and jQuery:
$("#ricerca").click(function(){
var e = jQuery.Event('keypress');
e.which = 13; // #13 = Enter key
$("#address").focus();
$("#address").trigger(e);
});
I want to simulate the "Enter" press INSIDE the #address field, by clicking on the #ricerca button. It is necessary that the cursor is inside the #address field when I press the button.
Can you please say me where are the errors?

define what should happen on keypress event for #address. Look at this code. Press enter key from insde the text box and then click on the button, both trigger the keypress event.
demo - http://jsbin.com/ocohev/1/edit
$(function () {
$('#address').keypress(function (event) {
if (event.which == 13) {
alert("enter pressed");
//return false; only if needed
}
});
$("#ricerca").click(function () {
var e = jQuery.Event('keypress');
e.which = 13; // #13 = Enter key
$("#address").focus();
$("#address").trigger(e);
});
});

Use this Jquery code:
$("#id_of_textbox").keyup(function(event){
if(event.keyCode == 13){
$("#id_of_button").click();
}
});

JavaScript: Pressing enter on a text input invoking a function

http://codepen.io/abdulahhamzic/pen/YqMQwB
How do I make it so that when I press enter on a text input, it calls a function? I tried using this:
<input type="text" onkeypress="clickPress()">
But the problem is I only want to press enter to call that function, not press any key. How do I achieve that?
2022 Update: onkeypress is deprecated.
You can use onKeyDown instead
What you'd want to do is check whether the event's key is the enter key:
In your html, add the event argument
<input type="text" onkeypress="clickPress(event)">
And in your handler, add an event parameter
function clickPress(event) {
if (event.keyCode == 13) {
// do something
}
}
2022 Update: event.keyCode is deprecated on many browsers.
You should do this now:
function clickPress(event) {
if (event.key == "Enter") {
// do something
}
}
Use a form instead (the submit event only runs once instead of every key press):
// Attach the event handler to the form element
document.querySelector('.js-form')?.addEventListener('submit', e => {
e.preventDefault();
alert(e.currentTarget.myText.value);
});
<form class="js-form">
<input type="text" name="myText">
</form>
The Enter button has a keyCode of 13, so you can use the keypress event using jQuery
$("input").keypress(function(event) {
if (event.which == 13) {
alert("Enter was pressed");
}
});
or, in pure javascript:
<input type="text" onkeypress="clickPress(event)">
function clickPress(event) {
if (event.keyCode == 13) {
// do something
}
}
Get the event's keycode and test if it's enter (keycode 13)
<script>
function clickPress(e){
if (event.keyCode == 13) {
// Enter was pressed
alert("enter");
}
}
</script>
<input type="text" onkeypress="clickPress(event)" />
jsfiddle
There could be several "better" ways to do what you want to do but just for the sake of simplicity, you could do this:
<input type="text" id="txt">
Instead of listening to the onkeypress you could attach an event listener within the <script></script> tags and do this:
var myText = document.getElementById("txt");
myText.addEventListener("keyup", function(e) {
if (e.which === 13) {
//The keycode for enter key is 13
alert(e.target.value);
}
});
And yeah this is definitely a duplicate question.

prevent form from submitting when keypress = 13 on a certain inputbox inside a form

Good day,
Can anyone please help me how can I stop my form from submitting whenever I press "enter" on a certain input box inside a form.
I have a table where use can dynamically add/remove row. And I have also an input box where user types/input number of rows he/she want to add. What I want to do is, the user can press enter instead of clicking the add row button when hes on the add row input box without actually submitting the form.
here is my js:
$("#toBeAdded").bind("keyup",function(e){
var code = e.keyCode || e.which;
if(code == 13) { //Enter keycode
console.log("enter");
return false;
e.preventDefault();
}
});
my html
<form>
<div>
<input name='amout'></amount><input name='qty'></amount>..etc
</div>
<input type="text" id="toBeAdded" class="form-control">
<div class="input-group-btn ">
<button type="button" id="btnAddRow" class="btn btn-primary ">Add Row</button>
</div>
</form>
the above code doesnt work, it does display log message but then it will submit the form after. any thoughts please
Change the keyup event to keydown
$("#toBeAdded").on("keydown",function(e){
You can not cancel the action after it has happened.
You are returning from callback before calling preventDefault(). Switch the order and it should work.
$("#toBeAdded").bind("keyup",function(e){
var code = e.keyCode || e.which;
if(code == 13) { //Enter keycode
console.log("enter");
e.preventDefault();
return false;
}
});
Try this, use the keypress event it runs before submit so you can abort:
$('form').find('input').keypress(function(e){
if ( e.which == 13 ) // Enter key = keycode 13
{
return false;
}
});

How to set the value of a textbox when it has focus

I have a textbox with a keydown handler. The handler detects if you press escape and if so it is meant to clear the textbox value. However, calling tb.value = "" normally works, unless the textbox has focus in which case it does nothing. I suspect I have to select the text and delete it, but how? This is in Firefox 12.
Have a look at this:-
LIVE DEMO
HTML:
<input type="text" id="content" />
JS:
$(document).keyup(function(e) {
if (document.activeElement.nodeName == 'INPUT')
{
if (e.keyCode == 13) { // Enter
alert('Enter Key Up');
}
if (e.keyCode == 27) { // Esc
alert('Esc Key Up');
$('#content').val("");
}
}
});

How can I disable the ENTER key on my textarea?

<form name='qform'>
<textarea name='q' rows='3' cols='60' wrap='hard' id='q' onkeydown="if (event.keyCode == 13) document.getElementById('clickit').click()"></textarea>
<input type='button' value='search' id='clickit' onclick="get();">
</form>
I have this form... it doesn't have a submit button because I am using jquery and under this form is a div area where the results will be shown. It is a search engine that does not have an input box but instead has a textarea. This is because it will be a multiple word searcher.
The problem is that if I press enter, the query is submitted and everything is ok ... but the focus on textarea goes down one line and that is a problem for me.
Basically I want the enter to have that one function only(submit) end nothing else.
$(document).ready(function() {
$('textarea').keypress(function(event) {
if (event.keyCode == 13) {
event.preventDefault();
}
});
});
Why not just use <input type="text"> if you don't want multiple lines? You mentioned it will be a "multiple word searcher". Why does this require a <textarea>?
Update
Try this
$('textarea').bind('keypress', function(e) {
if ((e.keyCode || e.which) == 13) {
$(this).parents('form').submit();
return false;
}
});
In the jquery function, use event.preventdefault and next do what you like.
For example
<script>
$("a").click(function(event) {
event.preventDefault();
//Do your logic here
});
</script>
http://api.jquery.com/event.preventDefault/
Pure javascript:
document.addEventListener('keypress', function (e) {
if (e.keyCode === 13 || e.which === 13) {
e.preventDefault();
return false;
}
})

How to press a button with Enter Key

How to bind click(from Button1's click event) event in textbox When I pressed the enter key
$('#idoftextbox').keypress(function (e) {
var code = e.keyCode || e.which;
if (code === 13) {
//enter has been pressed
};
});
<input type="text" name="textbox" id="textbox" />
$("#textbox").bind('keypress', function(e)
{
if(e.which == 13)
{
// enter key was hit, do what you need to do here
}
});
Since you didn't say what "textbox" means to you (as it can be textarea too), I assumed some dummy markup that I posted and then I bound the event to it.
I don't see the reason for binding an event to click and then bind event after that to the element.
