Parsley: How to prevent validation when pressing buttons other than submit?

Thank you for any help.
I am trying to use Parsley for Form Validation. My form has one submit button and some other buttons to dynamically add inputs to the form. But when I press these other buttons, form validation is carried out. But I am not submitting any form.
How to prevent form validation from happening when I press other buttons than submit button?
Sorry, I dont know how to JS Fiddle. My code is like the following:
<form method="post" action="confirm" data-parsley-validate>
<input id="brand" data-parsley-trigger="submit" required />
<button id="addQuantity">Add</button>
<input type="number" required data-parsley-trigger="submit" />
<input type="submit" value="Submit">
</form>
When I press Add, the form is validated. How should I prevent this?
Thank you very much.

The tag button which was introduced in HTML5 is equivalent to input type="submit" hence when you press add it will automatically fire submit action. What you can do is replace the tag to input type="button" or you can prevent the default action in jquery like this
<script>
$('#addQuantity').click(function(event)
{
event.preventDefault();
//do your action goes below
});
</script>

I found adding formnovalidate to the button skipped form validation for the form only when clicking that button.

Ensuring form does not submit on enter but instead runs function

I think that I understand that "button" are supposedly the correct way to achieve the result I desire; somehow they are supposed to be different from submit buttons. But I don't understand how to get the result I want.
I have the following:
<form action="http://www.google.com">
<input type="text" id="box1">
<button id="button1" onclick="myFunction()">Submit</button>
</form>
If a user clicks the button, the function runs correctly. (The function ultimately pulls the value from box1) and does something with it). However, if while the user has their cursor inside the textbox, they hit enter on their keyboard, the form submits and links to google.
How can I make it so that hitting enter in box1 does not change the page, and instead runs myFunction?

Add proper event handlers and listen for the submit event instead
<form action="http://www.google.com" id="myForm">
<input type="text" id="box1">
<button id="button1">Submit</button>
</form>
<script type="text/javascript">
document.getElementById('myForm').addEventListener('submit', function(event) {
event.preventDefault();
myFunction()
}, false);
</script>

Best way to form submission without using form action in JavaScript

I am building a PhoneGap application using JavaScript, HTML and jQuery Mobile.
All the HTML is in the same file, separated into <div data-role="page"> as pages.
Several pages have a form including one or more text/selection input and a submit button.
The submit is not a traditional form submit button but a button which using onClick runs a JavaScript function which can do many things.
I want the form to have this features:
When pressing the button and after running the function, clear the form.
In some cases the function should change the page.
The enter button on one of the inputs should submit the form (Activate the function).
Should I use the form HTML tag? If so what should I use for action? How to clear the form?
etc.

If you are trying to bind onClick to an input type="submit" then you're gonna have a bad time.
Unfortunately even if you return false or e.preventDefault when clicking that button, the form still sends the submit trigger so once your onClick code is finished then it will submit.
Example:
<form action="woot.php" method="POST">
<input type="submit" value="submit" onClick="alert('You clicked me! How could you?! It's cool the form will still go to woot.php. return FALSE wont help you either.'); return FALSE;">
</form>
What you probably want to do:
<form action="woot.php" method="POST">
<input type="submit" value="Submit" onSubmit="alert('You aint goin nowhere!'); return FALSE;">
</form>
What you should do:
<form action="woot.php" method="POST">
<input type="button" value="Button" onClick="alert('Away with you!'); window.location = 'http://www.google.com/';">
<input type="button" value="Button" onClick="someCoolFunction();">
</form>

I wouldn't use type="button", especially if you want to have the best chance of the form submitting when the user presses enter.
Use your regular form <input type="submit"> and then your JavaScript:
$('form').submit(function(e) {
// all your form handling here;
if (your_form_was_validated_and_handled) {
$('input[type!="submit"]').val('');
}
e.preventDefault();
});
Generic fiddle: http://jsfiddle.net/

You can still use the form tag, as it's useful for markup.
Just make sure that your buttons have attribute
type="button"
otherwise the button will submit the form by default.
To reset the form:
function resetForm() {
$('#form').each(function(){
this.reset();
});
}

Input field with onchange fails to trigger when user click button in another form

I have a page with multiple small forms on it. Each form has one input field that has an onchange function which will submit it's form to a url that returns a no data status.
Things work fine, submitting form after form, until the user clicks on a small form that has ONLY a submit button in it. This click works, but abandons the change in the previous field resulting in its onchange not firing the click at the bottom of the changed function fails (still trying to understand the firebug trace).
What's going on? is there a fix for my structure?
UPDATE:
First I tried simply delaying the action of the submit, but no luck.
I have hidden the and added an <input button> to the chain of "events" so that the focus has a place to come to rest before the real submit tries to happen -- the code below has been updated. So the question now becomes:
Is this as simple as it can be?
Script:
$(function() {
$('input,select').change(changed);
});
function changed(){
...
$(this).parents('form').find(':submit').click();
}
function doSubmit(elt, id)
{
$(elt).focus();
setTimeout(function(){
$(id).click();
}, 400);
}
One of may small forms:
<form class="clean" method="POST" action="QuoteProApp.php">
<input type="submit" value="field" name="btn_update" style="display: none;">
<input type="hidden" value="000242" name="quote_id">
<input type="text" maxlength="15" size="3" value="" name="q[cost][4][1][unit]">
</form>
The offending click goes into this form:
<form class="clean" method="POST" action="QuoteProApp.php">
<input type="hidden" value="000242" name="quote_id">
<input type='button' name='btn_close' value='Close' onclick='doSubmit(this,"#CLOSE");'>
<input id='CLOSE' type='submit' name='btn_close' value='Close' style='display:none;'>
</form>

Might be totally irrelevant, but your selector for the change event includes your submit input too. Can you change it to:
$('input[type="text"],select').change(changed);
to see if anything changes?

The solution turned out to be to create a button tag, set the focus explicitly to a it, and then set a timeout to click the real, but hidden, submit input tag. This allows the change in focus to run the submit associated with it and then continue with the explicit submit of the page.
The question has been updated to show this solution.

html button v.s. html submit?

I have an input text box and a search submit button, and when user clicks the Search submit button, I want to redirect user to url http://testsearch/results.aspx?k=<value of text box k>, for example, if user put "StackOverflow" into text box and then clicks the search button, I want to redirect user to the following page,
http://testsearch/results.aspx?k=StackOverflow
I find when I use button for Search button, it works (see below source codes),
<input type="text" id="k" name="k" />
<input type="button" id="Go" value="Search" onclick="location.href = 'http://somemachine/Search/results.aspx?k='+document.getElementById('k').value;"/>
but when I use submit for Search button, it does not works (see below source codes), why?
<input type="text" id="k" name="k" />
<input type="submit" id="Go" value="Search" onclick="location.href = 'http://somemachine/Search/results.aspx?k='+document.getElementById('k').value;"/>
thanks in advance,
George

You can even use the submit button this way:
<input type="submit" id="Go" value="Search" onclick="document.location='http://testsearch/results.aspx?k=StackOverflow'; return false;" />
Semantically submit button is used to submit forms not redirect pages. You should use normal button type for this. However as i showed you can use the submit button too but that is not semantic i think.
The below line prevents the form from being submitted.
return false;
That is what you are missing in your code :)
Thanks

<button>-elements and <input type="button"/> don't do anything by default, unless you tell them to do something with Javascript.
<input type="submit"/> will submit the form it is in.
So, if <input type="submit"/> won't work, you got it probably not in the <form/>-element itself.

If that's the only field in your form, simply set the form's method to "get" and it'll work.
<html>
<body>
<form action="http://localhost/mytest" method="get" >
<input type="text" id="k" name="k" />
<input type="submit" id="Go" value="Search" />
</form>
</body>
</html>

<button> means "put a button in the page and do whatever the onclick event says". So if you don't write an onclick handler the page doesn't do nothing.
If you use submit is ok, because you want to redirect to another page.
If you want to use button anyway you can do this way:
<script>
function doTheSearch() {
// do the submit mannually
document.getElementById('myForm').submit();
}
</script>
<form id="myForm" action="results.aspx">
<input type="text" id="k" name="k" />
<input type="button" id="Go" value="Search" onclick="doTheSearch();" />
</form>
Warning: submit button with onclick
If you have a submit button (inside a form, it is, a working submit button) with an onclick event, some browsers will:
1) execute onclick
2) execute submit
your onclick tries to redirect but the submit button wins.
If you want to avoid it you have some options:
a) change submit button to normal button
b) avoid the submit thing (add onsubmit="return false;" to form element)
c) use the submit procedure (form action="..." method="get", no onclick event), the browser will be happy and you can control the submit in the onsubmit event (you can cancel it or not).

make sure you got the input's in a form tag with a GET method:
<form action='http://testsearch/results.aspx' method='GET'>
... inputs
</form>

If I'm understanding correctly, it is not working because it is not in a form tag. If you put it in a form tag with method="get" it should work. The button works because it does not have to be in a form.
