how to assign the "Enter key" to an onclick event?

here i have number input bar with a tag assigned as button , i have an onclick function . how can i make the oncklick to be executed when the user press enter ? ( at this point the user will input a number in the box and press the button with the mouse - how can i make it so the user will input the number and press Enter and the same onclick function will be executed ? )
many thanks in advance.
i tried some codes but they wont work
enter code here
<div id="foot1">
<form action="" method="" name="vform">
<input type ="number" min="0" max="10000000"
placeholder="PEEM it!" value="" id="footbar" />
<div id="foot2">
<li class="foot" alt="foot" title="FOOT (ft)" onclick="runfoot()"></li>
</div>
</div>

You can use the keydown event or similar (keyup, keypress):
document.addEventListener('keydown', function(event) {
const ENTERKEY = 13;
if (event.keyCode === ENTERKEY) {
runfoot()
}
});
https://developer.mozilla.org/en-US/docs/Web/Events/keydown

Just use jQuery's click:
$(document).on("keydown", e => {
if (e.key == "Enter") {
$(".foot").click();
}
});

You can try this:
<div id="foot1">
<form action="" method="" name="vform" onsubmit="return false">
<input
type="number"
min="0"
max="10000000"
placeholder="PEEM it!"
value=""
id="footbar"
/>
<div id="foot2">
<li class="foot" alt="foot" title="FOOT (ft)" onclick="runfoot()">
</li>
</div>
</form>
</div>
<script>
document
.getElementById('footbar')
.addEventListener('keyup', function(event) {
const key = 13;
if (event.keyCode == key) {
runfoot();
}
});
</script>

Unable to submit form on keypress

i want to submit a form with and enter key stroke when the user enters a username and password.I get an alert coming back from my function when the enter key is pressed.But after that it doesnt submit the form. What am i doing wrong?
<form id="myForm" action="#" onsubmit="return false;" >
<div>
<input type="text" id="username" />
</div>
<div>
<input type="password" id="password" />
</div>
<div>
<button type="submit" id="btnLogin" onclick="myFunction(0)">Log in</button>
</div>
<script type="text/javascript">
function myFunction(e) {
if ((e && e.keyCode == 13) || e == 0) {
alert("The form was submitted"); // this alert gets called,but my form doesnt get submitted
document.forms.myForm.submit();
}
}

You can use like this.(Use jquery)
1.Change Input type submit to button
2.Change the code for submitting form
3.Write a keyPress event for the form
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm" action="test.html" >
<div>
<input type="text" id="username" />
</div>
<div>
<input type="password" id="password" />
</div>
<div>
<button type="button" id="btnLogin" onclick="myFunction(0)">Log in</button>
</div>
</form>
<script type="text/javascript">
function myFunction() {
alert("form submitted");
document.getElementById("myForm").submit();
}
$('#myForm').on('keydown', function (e) {
if (e.which === 13) {
myFunction();
}
});
</script>

1) Remove return false from the form onsubmit event.
2) Remove onclick event from the button.
3) Using JS, bind a submit event to the form and do what you need in the event handler, as below:
var loginForm = document.getElementById('myForm');
loginForm && loginForm.addEventListener('submit', myFunction);
function myFunction(event) {
event.preventDefault();
alert("form is about to be submitted...");
loginForm.submit();
}
<form id="myForm">
<div>
<input type="text" id="username" />
</div>
<div>
<input type="password" id="password" />
</div>
<div>
<button type="submit" id="btnLogin">Log in</button>
</div>
</form>
Even better, remove all the JS and keep only the form as in my answer. It would submit the form on enter as that's the default behaviour when there is a button/input with type submit!

You can try this without checking keyCode. You can enter key from any input fields or button inside the form.
function myFunction(e) {
var username = e.target.querySelector('#username');
var password = e.target.querySelector('#password');
if(username.value && password.value){
alert("The form was submitted");
return true;
}
return false;
}
<form id="myForm" action="#" onsubmit="return myFunction(event)">
<div>
<input type="text" id="username" />
</div>
<div>
<input type="password" id="password" />
</div>
<div>
<button type="submit" id="btnLogin">Log in</button>
</div>
</form>

I dont think you really need javascript for this as realistically pressing enter inside a form will usually submit the form.
Notice in the example below that all we are really doing is targeting
the submit event for the form and this also includes hitting the enter
key.
However to satisfy your question
Using jQuery you could try binding the keypress event to the button click submit event.
Something like this:
$("#btnLogin").blur();
$('#btnLogin').focus().click();
p.s. remember to close your <form> tag with </form>
Example
$('#myForm').submit(function() {
var confirmSubmit = confirm("Submit the form?");
if(confirmSubmit)
{
$("#btnLogin").blur();
$('#btnLogin').focus().click();
}
else
return false;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm" action="yourPage.html">
<div>
<input type="text" id="username" />
</div>
<div>
<input type="password" id="password" />
</div>
<div>
<button type="submit" id="btnLogin">Log in</button>
</div>
</form>

How can I submit a form when the user presses the `Insert` key?

How can I prompt for confirmation before submitting a form after they press the Insert key, and submit the form without confirmation when the user pushes the Enter/Return key ?
Summary of actions intended
INSERT : Prompt for confirmation. Submit form if confirmed.
ENTER : Submit form.
I have the following html form :
<form action="hhhhhhh.php" method="post" >
<input type="text" name="DatInvNew"/>
<input type="text" name="SumInvNew"/>
<input type="text" name="KolInvNew"/>
<input type="submit" value="next"/>
</form>

Here is the answer..
Try it once, Just copy and past it..
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('#inputform').on('keydown', 'input', function (event) {
switch(event.which) {
case 13: // enter
event.preventDefault();
var $this = $(event.target);
var index = parseFloat($this.attr('data-index'));
$('[data-index="' + (index + 1).toString() + '"]').focus();
break;
case 45: // insert
$('#click-to-submit').trigger('click');
break;
}
});
});
</script>
<form id='inputform' action="hhhhhhh.php" method="post">
<input type="text" name="DatInvNew" data-index="1" />
<input type="text" name="SumInvNew" data-index="2" />
<input type="text" name="KolInvNew" data-index="3" />
<input type="submit" value="next" class="click-to-submit" id="click-to-submit" />
</form>

The following example does these things (as per the original question) :
INSERT : Prompt for confirmation. Submit form if confirmed.
ENTER : Submit form.
document.onkeypress = function (e) {
e = e || window.event;
if(e.keyCode == 45) {
if(confirm("Would you like to submit this form?")) {
document.getElementById("myForm").submit();
}
} else if (e.keyCode == 13) {
document.getElementById("myForm").submit();
}
};
And change your html slightly :
<form action="hhhhhhh.php" method="post" id="myForm">
<input type="text" name="DatInvNew"/>
<input type="text" name="SumInvNew"/>
<input type="text" name="KolInvNew"/>
<input type="submit" value="next"/>
</form>

Clear Form after submit to iframe

I have form which need to be submited to another domain, like this:
<form id="myform" action="https://example.com" target="myiframe" method="POST">
<input type="text" name="email" value="">
<input type="text" name="name" value="">
<input type="text" name="phone" value="">
<input type="submit" name="submit" value="Submit">
</form>
And iframe:
<iframe style="display:none;" name="myiframe" src=""></iframe>
This work fine, but after submit form it stays filled.
So, how to clear (reset) form after submit?

Use an event-listener to trigger the submit and the clearing.
First, change the submit button to a regular button with a proper id (you should do the same to the other elements):
<input type="button" name="submitButton" id="submitButton" value="Submit" />
Then bind the event-listener to the button with JavaScript:
<script type="text/javascript">
document.getElementById('submitButton').addEventListener('click', function ()
{
handleTheForm;
}, false);
</script>
Wherea handleTheform is a method, defined accordingly:
<script type="text/javascript">
function handleTheForm()
{
document.forms[0].submit(); // Submit the form.
document.forms[0].reset(); // Clear the form.
}
</script>
Edit To handle the Enter button, simply add an event-listener for buttons and check which key is being pressed:
<script type="text/javascript">
document.addEventListener('keypress', function (e)
{
var key = e.which || e.keyCode;
var enterKey = 13;
if (key == enterKey)
{
handleTheForm;
}
});
</script>
Your final picture should look something like this:
<form id="myform" action="https://example.com" target="myiframe" method="POST">
<input type="text" name="email" id="email" value="" />
<input type="text" name="name" id="name" value="" />
<input type="text" name="phone" id="phone" value="" />
<input type="button" name="submitButton" id="submitButton" value="Submit" />
</form>
<script type="text/javascript">
function handleTheForm()
{
document.forms[0].submit(); // Submit the form.
document.forms[0].reset(); // Clear the form.
}
document.getElementById('submitButton').addEventListener('click', function ()
{
handleTheForm;
}, false);
document.addEventListener('keypress', function (e)
{
var key = e.which || e.keyCode;
var enterKey = 13;
if (key == enterKey)
{
handleTheForm;
}
});
</script>
You might have to tweek something a little but since I haven't manage to test this.

This solution is applicable to your problem
// code from answer with bind() transfered to plain javascript
function SubmitWithCallback(form, frame, successFunction) {
var callback = function () {
if(successFunction)
successFunction();
frame.removeEventListener('load', callback, false);
};
frame.addEventListener('load', callback, false);
form.submit();
}

You can easily achieve this using jQuery by
$("#formId").reset();
Hope this helps...

jQuery Mobile: Why are onClick and onKeyPress events not working?

In my jQuery Mobile code, I have some onClick and onKeyPress events but they are not firing. I am converting my client's website to a mobile version that includes lot of javascript functions. I don't know if it works if I convert everything into jQuery but I prefer not to do so and would like to keep the javascript functions as it is.
Is there a way to make this work entirely with javascript and not with jQuery?
onClick="javascript:alert('test');" seems to work fine. It's just the functions that are not being called.
http://jsfiddle.net/jetlag/CtkTV/1/
HTML:
<div data-role="fieldcontain">
<label for="textA">Input A</label>
<input class="inputField" id="textA" value="" type="text" onFocus="javascript:clearText(this);" value="This is default text A" />
</div>
<div data-role="fieldcontain">
<label for="textB">Input B</label>
<input class="inputField" id="textB" value="" type="text" onKeyPress="javascript:keyPressEvent(e);" onFocus="javascript:clearText(this);" value="This is default text B" />
</div>
<div class="ui-grid-b">
<div class="ui-block-a"><input type="button" id="goButton" onClick="javascript:goButtonPress();" value="Go" />
</div>
<div class="ui-block-b"><input type="button" id="testButton" onClick="javascript:alert('Alerted!');" value="Alert" />
</div>
</div>
Javascript:
function keyPressEvent(e) {
var evt = e || window.event;
var keyPressed = evt.which || evt.keyCode;
if (keyPressed == 13) {
document.getElementById('goButton').click();
evt.cancel = true;
}
}
function goButtonPress() {
alert('Button Pressed");
}

Working example: http://jsfiddle.net/Gajotres/aLB6T/
While there's nothing wrong with inline java script you should not use it when working with jQuery Mobile. Because of its architecture it can cause big problems. That is why if possible use classic jQuery.
$(document).on('pagebeforeshow', '#index', function(){
$(document).on('click', '#testButton', function(){
alert('Alerted!');
});
$(document).on('click', '#goButton', function(){
alert('Button Pressed');
});
$(document).on('keypress', '#textB, #textA', function(evt){
var keyPressed = evt.which || evt.keyCode;
alert(keyPressed);
if (keyPressed == 13) {
document.getElementById('goButton').click();
evt.cancel = true;
}
});
});

There is no e it should be event in your markup. i.e javascript:keyPressEvent(event)
<input class="inputField" id="textB" value="" type="text" onKeyPress="javascript:keyPressEvent(event);" onFocus="javascript:clearText(this);" value="This is default text B" />
Also
Your quotes are at wrong:-
function goButtonPress() {
alert('Button Pressed"); <-- here quotes should match
}
