When I try to submit a form, either via an input[type=submit] or by calling form.submit(), Parsley validates the form and cancels the submission if invalid. Is there any way I can skip that validation since I'm manually calling validate on sections of my form?
Specifically what I'm trying to achieve is submitting partial versions of the form, so I validate a group and only that portion is sent to the server (even if the rest of the form is still not valid).
I you want to cancel Parsley default validation on submit event, you'll have to remove the submit.Parsley binded event on your form.
Doing a $('#yourform').off('submit.Parsley'); should solve your issue.
Best
Edit: For Parsley2, since events names have changed, it should be $('#yourform').off('form:validate');
if you want to skip single element just use :
data-parsley-excluded
Form fields that won't be validated by Parsley. For example, if you
want to add disabled and hidden fields to the existing list, use:
data-parsley-excluded="input[type=button], input[type=submit],
input[type=reset], input[type=hidden], [disabled], :hidden"
but if you want to validate a specific groupd then use:
data-parsley-group
Assign a group to a field for specific group validation. eg:
data-parsley-group="signup". This way, you could only validate a
portion of a form and not all the fields.

When running the submit in JS you can do:
$('#yourform').parsley().destroy();
So with jQuery in code, it could look like this:
var $myForm = $('#yourform');
$("#submit-button").on('click',function(e){
e.preventDefault();
$myForm.parsley().destroy();
$myForm.submit();
});
As I answered here, adding formnovalidate to the button seems to work

Using ASP.NET MVC I've created a multistep form, for the client side validation I've picked Parsley.js, all works fine except when moving to a previous step in the form the validation is getting triggered (which makes perfect sense since the form is being submitted).
My Parsley related code currently looks like this
element.parsley({
trigger: 'change',
successClass: "success",
errorClass: "error",
classHandler: function (el) {
return el.$element.closest('.c-input');
},
errorsWrapper: '<p class="o-col-12"></p>',
errorTemplate: '<span></span>',
});
Where the element is my form.
Is there an easy way of saying to parsley that the validation shouldn't occur when hitting a specific button (can't see anything in the documentation...) or do I need to rework how the validation currently is attached. So only triggering the validation when hitting the next/submit button.
And yes I've looked at the multistep form example they have on the parsley site but that already has all the steps loaded and just toggles those, I need to submit between steps since server side code needs to happen.
I think you're looking for the novalidate attribute:
This Boolean attribute indicates that the form is not to be validated when submitted. If this attribute is not specified (and therefore the form is validated), this default setting can be overridden by a formnovalidate attribute on a or element belonging to the form.
Parsley respects it.
I've been trying for like 2 hours to get this form validator to work, but I can't..
http://ink.sapo.pt/javascript/Ink.UI.FormValidator.2/#Ink_UI_FormValidator_2-FormValidator_FormElement-FormElement
I mean, form gets validated when I press the submit button, and form posts data only after all fields are correctly.
But what I need is to actually set up the onSuccess callback, so that instead of using method="post", i can a function easily.
You'll need to use the neverSubmit option to do this.
This is a rather obscure option, but it's there in the FormValidator class (you may be looking at the FormElement class, which refers to each input element in a form and takes options such as that input element's label and validation rules.)
I've made a short example based on the official sample.

I am using jquery validate plugin to validate form fields . I am also using jqtree . on click of every child node a section of form is visible to user, which is supposed to be filled with values.For every child there is a form content to be filled. Entire tree content is declared within one form only. I have a button in the form which on click generates json file. I am calling the function below to validate form
$("myform").validate();
....
if($("#my-form).valid())
generate the json file
but this is not validating the entire form. suppose I am on childNode1 it validates only form section defined for childNode1. As far as I have understood jquery validate plugin should validate entire form when correct form id is specified. But can anyone tell me what has gone wrong in my approach?
The .validate() method does not "validate the form". It only initializes the plugin on the form. .valid() will programmatically trigger a validation test.
Your code:
$("myform").validate();
....
if($("#my-form).valid())
generate the json file
$("myform") - Is that supposed to be an id, class, or name? As you've written it, it's looking for a <myform></myform> element.
$("#myform") // id="myform"
$(".myform") // class="myform"
$("[name='myform']") // name="myform"
Is your form element called myform or my-form? If it's the same <form> element, then the two jQuery selectors would be the same.
$("#my-form) is missing the closing quotation mark.
If the id of the <form> element is "myform", then your code should be...
$("#myform").validate(); // <- initialize the plugin
....
if ($("#myform").valid()) { // <- test the form's validity
// generate the json file
....
}
OP Title: jquery validate plugin, validating form fields of only current screen
Your question does not seem to have anything to do with the title. There is only one form described in your OP, and since this is JavaScript, only the page that's loaded in the browser is relevant. Not sure what you mean by "current screen".
but this is not validating the entire form. suppose I am on childNode1 it validates only form section defined for childNode1. As far as I have understood jquery validate plugin should validate entire form when correct form id is specified.
By default, the plugin will not validate any form fields that are hidden. You would manipulate the ignore option to over-ride this behavior. Setting ignore to [] will tell the plugin to ignore nothing and validate all fields including the hidden ones.
I am working on a form with multiple fields and of course, a submit button.
How do I cancel the form submission if some fields are empty?
I tried putting a validation of javascript, input type="submit" onclick="check()" on the submit button.
But what I actually want is that, the page won't load so that, all other information in the text fields won't go away.
Like, what if the form has 100 fields and the user forgot to input one field and click the submit, it will show him an error message and all other fields will be cleared so he has to type it again.
I'm trying to prevent that.
I have multiple options to create this effect but I am currently trying to find a way on doing this.
Any other ways would be appreciated (like disabling the button when all mandatory fields are not filled, then enabling it at when everything is complete)
if the condition will be false click(event) returns false and nothing will happend
function check(){
if(validate === false)
return false;
}
Enjoy :)
You can simply return false from inside your check function to prevent the form from submitting.
I need to submit just one input field value to a cgi script via a web form.
I've added a couple of extra form controls (a check box and radio buttons) which manipulate the input value depending on the states selected.
When the form is submitted, the extra form field values are submitted as well which breaks the cgi script (which I don't have access to). I removed the 'name' attribute from the check boxes so they are not submitted but cannot do this for the radio buttons as it breaks their grouping.
How can I prevent radio button values from being submitted?
You can add a disabled attribute to them in the submit handler, this will prevent them from being serialized, either by jQuery or a normal <form> submission. For example:
$("#myForm").submit(function() {
$(this).find(":radio, :checkbox").attr("disabled", true);
});
Or you can .serialize() only the elements you want, for example:
$.post("myPage.cgi", $("#myForm input[type=text]").serialize());
Make them "unsuccessful". There are several ways to achieve this:
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.2
It is also possible to have two different forms: one that has visible form elements and one that has a hidden input that represents the end result to be submitted. You can either attach onchange handlers to your visible form elements so that they call some JavaScript to update the invisible field, or you can run a function as part of the onsubmit handler to set the invisible value directly before it is submitted.
Here's a jsFiddle demonstrating the second approach (the onsubmit handler): http://jsfiddle.net/gtU4J/
