I have dojo Vaslidation textbox with required set to "true". But when I hit the submit button and submit the form,the form is prevented from submitting, but doesnot display error messages either.
But when I click the textbox, it is highlighted to red and show the message.
My requirement is, When i click on submit without entering data or invalid data, it should display the error message without having to click the input field.
How do I achieve this?
Setup an event (dojo/on) to listen for the form submit and return true/false. See example here: http://dojotoolkit.org/reference-guide/1.10/dijit/form/Form.html#validate

I have a form made of buttons and a submit button. I want to submit only from the submit button.
I tried to use button type="button", but when I try to submit I get a "This field is required" error. How can I accomplish this?
Have you tried to set the Blank = True in models.py for the fields that do not submit?
I'm validating a Sign Up form where I'm displaying error message on the same page. When I'm entering the field value as per requirement and pressing SIGN UP button error message is going off but when I'm trying to insert another field that error message is not going off i.e it's still on the same page. Calling ajax for some functions also.
How can I resolve this problem?
I am using jquery validation for my form and i have set an invalidHandler that show an error on the top of form and scroll to that message.
I am trying to hide that message when field validation is success but i can not find anything in validate() option that will help me.
(not when user click submit.For example if i have one textbox on the form and click submit i display the message, when the user write something to textbox and it pass the validation i want to hide the message without the user click submit)
Maybe i can count the number of errors on success but i dont know how.
Thanks
if you give your error at the top of your form an id of 'foo',
<div id="foo">error here</div>
and set the errorContainer option, then when the form is valid again the element #foo will disappear
$("#myform").validate(
{
errorContainer: "#foo"
}
});
note the element #foo must be within the form
I am creating an MVC3 website and added a couple of security questions to the "My MVC Application" Registration routine in the form of dropdown boxes. I created a custom validator to check the second dropdown box and if the selected item is the same as the first then it shows an error message.
My problem is that the clientside validation triggers as soon as the second dropdown box loses focus. After the error is displayed, ideally, I should be able to change the selection in the first dropdown box and the validation error message for the second dropdown box should go away. But, of course, changing the first dropdown box does not trigger the clientside validation routine for the second dropdown box and the error does not go away.
I would appreciate it if someone who is well versed with the internalls of unobstrosive Ajax validation routines would guide me to a solution so that when the selection of one dropdown box changes the validation routine of both dropdown boxes is triggered.
Thanks a bunch for any pointers.
If you look at this question and my answer, you will see code for client-side validation where changing one field will trigger validation on another field, and will then stop after both fields' validation has run.
Even using the Post/Redirect/Get method, and including javascript to disable a button after it has been clicked, I am having a problem with users being able to just rapidly hammer a submit button and get multiple form posts in before server side validation can stop it.
Is there any way to stop this? I've even tried this method : how to implment click-once submit button in asp.net mvc 2?
And I've tried outright blocking the UI with jquery blockUI. I have BOTH client side and server side validation in place, and they work perfectly - but a user smashing the submit button twenty times in under a second just seems to keep breaking it.
Use javascript to wire the onclick event to disable the button.
If you are already doing that and you can still get multiple form posts, then the problem is a delay between the clicking of the button and the button being disabled, and you must be submitting the form multiple times during this delay.
To fix this, make the onclick event first make a call to stopPropagation() to stop the submit event. Then validate that the form is not in submission-blocked state. You can do this by creating a page-scoped javascript variable with a boolean value like can_submit. Test for can_submit being true before submitting the form. Set the can_submit = false when the button is disabled, so even if the button is not disabled fast enough, the form will not submit if the value has already been set to false.
In most cases I'd say that this isn't worth fixing - if a user is going to do something as silly as clicking submit 20 times they should expect to get an error.
The only real fix for this is to set up your action to only accept the same form once - add a hidden field that is set to a random value when the form is loaded. When the form is posted, save that value somewhere temporarily and if it is already there you have a duplicate request that shouldn't do anything.
