I am playing around with HTML 5 validation and localization and have managed to get some code working that allows me to localize the HTML 5 validation error messages (see below). My problem is, in Chrome when matching against a pattern you still get a pop up in English (or I guess whatever language you have Chrome set up in) 'please match the requested format'. How do you supress this pop up so that I can just use my own validation messages?
$(document).ready(function () {
var elementsInput = document.getElementsByTagName("input");
var elementsTextArea = document.getElementsByTagName("textarea");
for (var i = 0; i < elementsInput.length; i++) {
elementsInput[i].oninvalid = function (e) {
e.target.setCustomValidity("");
if (!e.target.validity.valid) {
switch (e.target.name) {
case "Name":
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna nimesi");
} else {
e.target.setCustomValidity("Please enter a Name");
}
break;
case "EmailAddress":
if (e.target.validity.valueMissing) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna sähköpostiosoitteesi");
} else {
e.target.setCustomValidity("Please enter an Email Address");
}
}
else if (e.target.validity.patternMismatch) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Virheellinen sähköpostiosoite");
} else {
e.target.setCustomValidity("Invalid Email Address");
}
}
break;
case "PhoneNumber":
if (e.target.validity.valueMissing) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna puhelinnumerosi");
} else {
e.target.setCustomValidity("Please enter a Phone Number");
}
}
else if (e.target.validity.patternMismatch) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Virheellinen puhelinnumero");
} else {
e.target.setCustomValidity("Invalid Phone Number");
}
}
break;
}
}
};
elementsInput[i].oninput = function (e) {
e.target.setCustomValidity("");
};
}
for (var j = 0; j < elementsTextArea.length; j++) {
elementsTextArea[j].oninvalid = function (e) {
e.target.setCustomValidity("");
if (!e.target.validity.valid) {
switch (e.target.name) {
case "Details":
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Täytäthän yksityiskohdat");
} else {
e.target.setCustomValidity("Please enter Details");
}
break;
}
}
};
elementsTextArea[j].oninput = function (e) {
e.target.setCustomValidity("");
};
}
});

If you enter your banking credentials incorrectly, you may see a message appear that says 'Please match the requested format' after you click 'Submit Credentials': This format is set by the bank and will be different for each bank.
setCustomValidity() In an input element, it is used to set the validationMessage property. It is really very easy to control a custom validation message in an HTML5 form. Let us find out how. This part is of utmost importance, as it will hide the error message when the user will enter the new data.
The default browser action is to display a popup message. You should use e.preventDefault(); to prevent it from popping up.
$(document).ready(function () {
var elementsInput = document.getElementsByTagName("input");
var elementsTextArea = document.getElementsByTagName("textarea");
for (var i = 0; i < elementsInput.length; i++) {
elementsInput[i].oninvalid = function (e) {
e.target.setCustomValidity("");
if (!e.target.validity.valid) {
switch (e.target.name) {
case "Name":
e.preventDefault();
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna nimesi");
} else {
e.target.setCustomValidity("Please enter a Name");
}
break;
case "EmailAddress":
e.preventDefault();
if (e.target.validity.valueMissing) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna sähköpostiosoitteesi");
} else {
e.target.setCustomValidity("Please enter an Email Address");
}
}
else if (e.target.validity.patternMismatch) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Virheellinen sähköpostiosoite");
} else {
e.target.setCustomValidity("Invalid Email Address");
}
}
break;
case "PhoneNumber":
e.preventDefault();
if (e.target.validity.valueMissing) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Anna puhelinnumerosi");
} else {
e.target.setCustomValidity("Please enter a Phone Number");
}
}
else if (e.target.validity.patternMismatch) {
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Virheellinen puhelinnumero");
} else {
e.target.setCustomValidity("Invalid Phone Number");
}
}
break;
}
}
};
elementsInput[i].oninput = function (e) {
e.target.setCustomValidity("");
};
}
for (var j = 0; j < elementsTextArea.length; j++) {
elementsTextArea[j].oninvalid = function (e) {
e.target.setCustomValidity("");
if (!e.target.validity.valid) {
switch (e.target.name) {
case "Details":
e.preventDefault();
if ("@Thread.CurrentThread.CurrentUICulture.Name.ToLower()" == "fi-fi") {
e.target.setCustomValidity("Täytäthän yksityiskohdat");
} else {
e.target.setCustomValidity("Please enter Details");
}
break;
}
}
};
elementsTextArea[j].oninput = function (e) {
e.target.setCustomValidity("");
};
}
});
Theoretically you can really put the e.preventDefault() right after if (!e.target.validity.valid) { but I noticed you didn't have a default: in your Switch, so I assumed you didn't want it there. In either case, you can use e.preventDefault() inside each individual case: where you want it, or you can put it after the if statement. Which ever suits your purpose better.

If you're running your own validation you can prevent any built-in HTML5 browser validation by setting the novalidate attribute of the form to "novalidate" like
<form name='testForm' method='POST' action='#' novalidate="novalidate">
This will tell the browser to prevent applying HTML5 auto-validation.
