ASP.NET MVC 3: Configuring unobtrusive validation

ASP.NET MVC 3 ofeers client side validation through the unobtrusive javascript and jQuery validation plugins. Most of the time the default behavior is fine, but what if you want to tweak the validation configuration?
Only validate the form fields when the form is submitted:
$(function() {
 var validationSettings = $.data($('#formToValidateId').get(0), 'validator').settings;
 validationSettings.onkeyup = false;
 validationSettings.onfocusout = false;
});

As you can see, it’s possible to change some settings through the  validator settings object. By setting  the onkeyup and onfocusout properties to false, the validation on blur and key up will be disabled.
Disable the validation on input fields with class ignore.
$(function() {
 var validationSettings = $.data($('#formToValidateId').get(0), 'validator').settings;
 validationSettings.ignore = '.ignore';
});


Setting the ignore property of validator settings object to .ignore will tell the jQuery validation plugin to ignore all input elements with class ignore during validation. 


Of course there are a lot more options you can configure. For a complete list of jQuery validation options have a look here.

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
