how to validate hidden doms

mc 3,681

I have a hidden value

<input type="hidden" asp-for="ImageUrl" />

<span asp-validator-for="ImageUrl" />

how to validate it?

jquery.validate will not validate the hidden doms.

Validating a hidden field populated on the server makes little sense. The user cannot see hidden fields. How does the user fix the validation error? Perhaps you wrote client side code that sets the hidden field?

to validate hidden fields, update the ignore selector which defaults to ":hidden".

$('#myForm').validate().settings.ignore = ".ignore"; // require ignore class to ignore
