I am trying to Validate a Form with Parsley JS But when I hit submit it's adding error class in all fields but I want that it should validate fields one by one.
So if the 5 inputs are required and I it submits without filling any of them so want to show error in the 1st input only. after that if i fill 1st input and left the other 4 then it should show error in the second input only. I am just using this code for my form now.
$('#formid').parsley( //nothing here for now );
Set a specific priority to each input in the order you want them validated. Parsley will stop validation as soon as an error is detected at a given priority level.

I have a form with a drop down list with two options ("MCQ" and "SEQ") and some fields. Selecting "MCQ" would hide fields used by "SEQ" and vice versa. I want to submit this form but the "please filled out this field" notice pops up. What should I do to submit this form?
I've searched around Stack overflow before looking possible solutions, some suggested placing "required" or "disabled" beforehand, however I would like a dynamic way of doing if possible but based it on which option the user selects since the user might leave everything empty and just submit if nothing is required.
Additional Information:
I'm using forms.ModelForm, the fields came from there.
I'm using js to hide and show the relevant fields.
I Appreciate any help/suggestions. :)
Your model should not define those fields as required, this way they can be empty when the form is validated:
class MyModel:
my_field = models.CharField(blank=True, null=True, length=500)
...
blank=True will tell your forms not return an error if this field is empty
I have used ng-disabled for my form validation for ADD button.
i.e. ng-disabled="conditionForm.$invalid". But , My form contains two text boxes which are hidden at first , and when a type is selected from drop down , only the respective Text box div should be visible. The Problem i'm facing is ,when the above ng-disabled validation is used , the ADD button is still disabled when one of the text box is selected and an input is provided. After the second input is also selected from the drop-down , then the ADD button is getting enabled.
Can you please provide me with an alternate validation , where the ADD button can get enabled every time a value is selected from drop down and a valid input is provided.
If you're ng-disabled is on a form being valid or invalid it sounds like those may have required inputs set. If that is case look at using ng-required so you can explicitly set required based on expression. You can then control when the form is valid.
The exact answer: Answer
I have a checkbox field which determines whether the proceeding client ID field has an attribute of data-validate required:true, or data-validate required:false which drives my forms validation.
<input type="text" name="stID" id="stID" data-validate="required:true" />
Using jquery i can change the requirement in real-time, along with show/hide and add/remove the error classes associated with that field.
$("#input[name='stID']").attr("data-validate","required:false");
var form=$("#standard");
form.validate().resetForm();
The issue lies when someone tries to submit the form, then changes the initial checkbox option (if true, ID isn't required otherwise if false, ID is required).
When this happens, despite the data-validate required:false being set and the error classes being hidden, the validation is still occurring and flagging the stID field.
Does the jquery validator plug in have a cache/array of fields which resulted in errors that it determines on submit and possibly isn't being cleared/reset when the resetForm function on our validation is called?
Found the solution, still needed to clear the data attribute associated with these fields producing errors after changing its requirement. This was done by
$("#stID").removeData();
I've got three form fields, two inputs and one textarea. When I hit the submit button before entering any data my browser says the first input field and the textarea must be entered, but the second input field is ignored. Does anyone got an idea how I should fix this?
Posted the code on http://jsfiddle.net/D5tk4/
Thanks!
Your input fields have id attributes but not name attributes. Inputs need to have name attributes.

I have a form in a modal window that is currently performing some validation.
(I am using ASP.NET MVC, JQuery UI, ajax forms, data annotations and unobtrusive is active)
When this validation triggers I have noticed so far that it does a few things:
1: my validation summary gets it's class changed from .validation-summary-valid to .validation-summary-errors
2: my invalid inputs have a class added to then called .input-validation-error
3: my validation messages get their class changed from .field-validation-valid to .field-validation-error
But there is something else that it is doing and I cant work out how it is tracking this.
I have a textbox that is required, before triggering the validation i can select inside this box, then select another box and the validation will be silent.
But as soon as i trigger the validation by clicking submit with an empty textbox, i can select the textbox and type something to remove the validation instantly, but if i then null it and select a different box this error is re-applied without re-submitting.
So my question is: what has changed, how does it know that I have attempted to submit already?
When validate is called, it adds a class to each input/select that is supposed to be validated. When the input/select is not valid it adds a class to the input/select:
class="input-validation-error"
When it is valid, it adds:
class="valid"
Validation only fires on the control when you change the value, not when it loses focus.
Validation fires on change, even before you submit the form. Take a required textbox, add a value to it, and tab off ... then go back and remove that value, and you should see the textbox highlighted red.
