HTML
<form action="die_issue_process.php" id="form" method="post" autocomplete="off">
<input type="text" name="item_name[]" />
<input type="button" name="add_item" value="Add More" onClick="addMore();" />
<input type="submit" id="Search" name="Search" value="Search" />
Javascript code:
function addMore() {
$("<DIV>").load("input.php", function() {
$("#product").append($(this).html());
});
}
Friends in this form I have single text box and add button to add text box according to the need. Here in this form I'm giving input thru a BAR CODE reader so once the bar-code is scanned the form gets automatically submitted but my requirement is it should be submitted only after giving the submit button
Note: my form gets auto submitted on first scan of input box itself.
Well, a barcode scanner, reads the barcode and submits automatically!
So I think you better change your input with the type "submit" to a button
<input type="button" id="Search" name="Search" value="Search" />
You can consider a barcode scanner as a very specialised keyboard. If you test your barcode scanner whilst in a text editor. You will see they just very quickly enter the string that the barcode represents, followed by a carriage return.
These are indistinguishable from the keystrokes required to manually perform the same operation, using the keyboard.
If you are focused on a text field in a form, pressing enter will often submit the form.
To prevent the enter key from submitting a form on a text field, you can kill that keystroke with an event handler, for example:
(function() {
var textField = document.getElementById('textFieldId');
if(textField) {
textField.addEventListener('keydown', function(mozEvent) {
var event = window.event || mozEvent;
if(event.keyCode === 13) {
event.preventDefault();
}
});
}
})();
If the scanner is feeding to a textbox, start your form with your submit button hidden. Only visiable it once the textbox has data input. this can be done by javascript..

I am trying to find out how to create a submittable chat entry. What I want is a text box that can wrap. From what I have seen so far, this is done with textarea. However, the text area does not let me submit by just pressing enter. It required a send button. How can I have the best of both worlds? (wrapping input text, but also being able to submit by pressing "enter")
This is the code that was working fine, but would not let me wrap text when I inserted text:
<form action="">
<input id="m" autocomplete="off"><button>Send</button>
</form>
This is my new code that will wrap text. It will submit, but only when I press the send button. I want to submit when the "enter" key is pressed:
<form action="" style="height: 8%">
<textarea name="m" style="height:100%; width: 80%"></textarea>
<button>Send</button>
</form>
I believe that the input id section let me submit when I pressed "enter" only, but textarea will not allow me to.
This code will submit the textarea content after pressing enter (like input). I added ids to both form and textarea:
var textArea = document.getElementById("chatBox"); // set the textarea as variable
textArea.addEventListener("keyup", function(event) { // listen to keypress on the textarea
if (event.keyCode === 13) { // 13 is the "Enter" key on the keyboard
document.getElementById("chatForm").submit(); // submit the form
}
});
<form id="chatForm" action="" style="height: 8%">
<textarea name="m" id="chatBox" style="height:100%; width: 80%"></textarea>
<button>Send</button>
</form>
Hope that helps.
You can catch keyup events on the textearea and then submit the form :
<form action="" id="yourForm">
<textarea name="m" onkeyup="submit"></textarea>
</form>
with :
function submit() {
document.getElementById('yourForm').submit();
}
I'm only using HTML and JavaScript.
I have one form
<form id="form1">
<input name="name" type="text" size="20">
</form>
And one button
<button onclick="outputname()" type="submit">Search</button>
So the idea is the user types a number on the form and clicks the search button and an action is performed (this works great).
However, if the user enters a number and hits the Enter button on keyboard the page is refreshed. The same happens on iPad. ("Return" button is displayed instead of "Go").
So I want the Enter button to work on keyboard and Go to work on iOS.
The idea is that the user enters a customer number and the relevant details are displayed.
Give an ID to both your input field and button, to be sure you trap the correct one:
HTML:
<form action="destination.html" method="post">
<input id="foo" name="name" type="text" size="20">
<button id="mybutt" onclick="outputname()" type="submit">Search</button>
</form>
Note that destination.html is where you want the data posted to. If you want it posted to the same file, just use: action="" or leave it out.
Javascript:
document.getElementById('foo').onkeypress = function(e){
if (!e) e = window.event;
var keyCode = e.keyCode || e.which;
if (keyCode == '13'){
var btn = document.getElementById('mybutt');
mybutt.click();
return false;
}
}

How to detect when the user presses Enter in an input field
Capturing the Enter key to cause a button click with javascript
Insert this:
action="post"
Inside your form tag. I.e., your form tag will have to be this way
<form id="form1" action="post">
In this case, you could manage the submit event, instead of key/click events.
<form id="form1" onsubmit="outputname()">
Submission events triggered by either a click or pressing enter will call outputname.
I am using a barcode scanner to enter data into input fields on a webpage. I set up the form and autofocus on the first input field. When the first barcode is entered into the first input field I would like focus to jump to the next input field. However, as soon as I enter the first barcode the form 'submits'. Here is the html I am using:
<form id="barcode1" name="barcode" method="Post" action="#">
<div>
<label for="S1">Barcode 1 </label>
<input id="S1" class="bcode" type="text" name="S1" autofocus/>
<label for="S2">Barcode 2 </label>
<input id="S2" class="bcode" type="text" name="S2" />
<label for="S3">Barcode 3 </label>
<input id="S3" class="bcode" type="text" name="S3" />
</div>
<p><input type="submit" name="Submit" value="Submit"></p>
</form>
I have tried solutions from similar SO questions here and [here] (http://jsfiddle.net/davidThomas/ZmAEG/), but they don't seem to work.
Ideally I would like to have a solution something like this (the second link above), so please let me know where or why this is not working and what I can do to fix it.
$('form').on('keypress','input',function(e){
var eClassName = this.className,
index = $(this).index('.' + eClassName) + 1;
if (e.which === 13){
e.preventDefault();
$('input.' + eClassName)
.eq(index)
.focus();
}
});
You need to return false in order to prevent the enter key from submitting the form.
The answer to this question will help you: Prevent form submission with enter key
//Press Enter in INPUT moves cursor to next INPUT
$('#form').find('.input').keypress(function(e){
if ( e.which == 13 ) // Enter key = keycode 13
{
$(this).next().focus(); //Use whatever selector necessary to focus the 'next' input
return false;
}
});
No need to make any changes to your bar scanner.
If your barcode scanner is a keyboard wedge, you should be able to configure the trailing character to a TAB.
It seems like, by default, your scanner is trailing with an ENTER (carriage return).
Another option would be to also check for a LF (decimal 10) in your javascript code.
Looks like your function will never get called because browser submits the form on Enter. You may have to suppress submit until all fields are filled (or some other condition) by intercepting submit event first.
$( "form" ).submit(function( event ) {
if(/*all req. fields are filled -> submit the form*/)
$(this).submit();
event.preventDefault();
});
i'm using button key for my project but this is not work when i push Enter Key.
why 'enter key' not working in this form?
<form action="" method="post">
<input type="text" >
<input type="button" >
</form>
how this is work with javascript, plz help me
i will not sue type="submit"
It seems you want implicit submission:
A form element's default button is the first submit
button in tree order whose form owner is that
form element.
If the user agent supports letting the user submit a form implicitly
(for example, on some platforms hitting the "enter" key while a text
field is focused implicitly submits the form), then doing so for a
form whose default button has a defined activation behavior
must cause the user agent to run synthetic click activation steps
on that default button.
Therefore, the button must be a submit button, not a button in button state:
<input type="submit">
I think an <input type="submit"> is what you want :)
$(form).on('submit', function{
//do whatever you want...
})
<form action="raftel">
<input name="name" type="text"/>
<input name="password" type="password"/>
<input type="submit"/>
</form>
I am trying to work out a way of making A return function as a tab or vice versa. When the user scans the barcode it moves to the next text field then on the last field it submits the form. Really of sure of this and jquery/ JavaScript to make it happen!
The default behavior of barcode scanners is to input the characters followed by "enter." If you meant you want the scanner to move to the next field instead, you can block the enter with something like:
<form method="post">
<input type="text" name="barcode" id="b1" />
<input type="text" name="otherfield" id="b2" />
<input type="submit" id="submit" />
</form>
<script type="text/javascript">
$('#b1').keydown(function(e){
if (e.keyCode == 13) { // barcode scanned!
$('#b2').focus();
return false; // block form from being submitted yet
}
});
</script>
