I use required
for a 1st check before submitting a form.
<form action="myform.php"> Foo: <input type="text" name="someField" required="required"> <input type="submit" value="submit"> <input type="submit" value="ignore"> </form>
Problem is, that I have an "ignore" button, which submits the form as well and the backend logic then sets a correct state in a DB. In this case (ignore) the validation is not desired (because there is no need to fill in field "Foo").
What's the best way to handle the 2 scenarios?
onclick
for the ignore button scenario and remove the attribute just before sending the form ( https://stackoverflow.com/a/13951500/356726 ).But actually I am looking for something smarter ....

Yes, duplicate of Required attribute HTML5
To remove the required attribute, select the element and call the removeAttribute() method on it, passing it required as a parameter, e.g. input. removeAttribute('required') . The removeAttribute method will remove the required attribute from the element.
g_form. checkMandatory = false; this will bypass the mandatory check and the form will be submitted. You can use in a client script (onsubmit) or in a client side UI action.
The formnovalidate attribute is a boolean attribute. When present, it specifies that the <input> element should not be validated when submitted. The formnovalidate attribute overrides the novalidate attribute of the <form> element. Note: The formnovalidate attribute can be used with type="submit" .
No JavaScript, no second form needed, and the validation can stay:
For exactly this use case the HTML5 spec has designed the formnovalidate
attribute for submit elements (like <input type=submit>
), as one of the attributes for form submission:
The
formnovalidate
attribute can be used to make submit buttons that do not trigger the constraint validation.
So simply put
<form action="myform.php"> Foo: <input type="text" name="someField" required> <input type="submit" value="submit"> <input type="submit" value="ignore" formnovalidate> </form>
Your #2 is a common approach. Something like:
$('input[value="ignore"]').click(function() { $(this).siblings('input[type="text"]').removeAttr('required'); });
Might have to use mousedown to beat submit.
