Prendendo dalla soluzione di Xhalent contrassegnata come risposta sopra, l'ho ampliata un po '.
$.validator.unobtrusive.parseDynamicContent = function (selector) {
var $selector = $(selector),
$jqValUnob = $.validator.unobtrusive,
selectorsDataValAttr = $selector.attr('data-val'),
$validationInputs = $selector.find(':input[data-val=true]');
if ((selectorsDataValAttr !== 'true') &&
($validationInputs.length === 0)) {
return;
}
if (selectorsDataValAttr === 'true') {
$jqValUnob.parseElement(selector, true);
}
$validationInputs.each(function () {
$jqValUnob.parseElement(this, true);
});
//get the relevant form
var $form = $selector.first().closest('form');
$jqValUnob.syncValdators($form);
};
/* synchronizes the unobtrusive validation with jquery validator */
$.validator.unobtrusive.syncValdators = function ($form) {
if ($.hasData($form[0])) {
var unobtrusiveValidation = $form.data('unobtrusiveValidation'),
validator = $form.validate();
// add validation rules from unobtrusive to jquery
$.each(unobtrusiveValidation.options.rules, function (elname, elrules) {
if (validator.settings.rules[elname] == undefined) {
var args = {};
$.extend(args, elrules);
args.messages = unobtrusiveValidation.options.messages[elname];
$("[name='" + elname + "']").rules("add", args);
} else {
$.each(elrules, function (rulename, data) {
if (validator.settings.rules[elname][rulename] == undefined) {
var args = {};
args[rulename] = data;
args.messages = unobtrusiveValidation.options.messages[elname][rulename];
$("[name='" + elname + "']").rules("add", args);
}
});
}
});
// remove all validation rules from jquery that arn't in unobtrusive
$.each(validator.settings.rules, function (elname, elrules) {
if (unobtrusiveValidation.options.rules[elname] === undefined) {
delete validator.settings.rules[elname];
} else {
$.each(elrules, function (rulename, data) {
if (rulename !== "messages" && unobtrusiveValidation.options.rules[elname][rulename] === undefined) {
delete validator.settings.rules[elname][rulename];
}
});
}
});
}
};
$.validator.unobtrusive.unparseContent = function (selector) {
var $selector = $(selector);
// if its a text node, then exit
if ($selector && $selector.length > 0 && $selector[0].nodeType === 3) {
return;
}
var $form = $selector.first().closest('form'),
unobtrusiveValidation = $form.data('unobtrusiveValidation');
$selector.find(":input[data-val=true]").each(function () {
removeValidation($(this), unobtrusiveValidation);
});
if ($selector.attr('data-val') === 'true') {
removeValidation($selector, unobtrusiveValidation);
}
$.validator.unobtrusive.syncValdators($form);
};
function removeValidation($element, unobtrusiveValidation) {
var elname = $element.attr('name');
if (elname !== undefined) {
$element.rules('remove');
if (unobtrusiveValidation) {
if (unobtrusiveValidation.options.rules[elname]) {
delete unobtrusiveValidation.options.rules[elname];
}
if (unobtrusiveValidation.options.messages[elname]) {
delete unobtrusiveValidation.options.messages[elname];
}
}
}
}
Quindi fondamentalmente funziona ancora come la soluzione di Xhalent sopra, ma ho aggiunto la possibilità di rimuovere le regole per gli elementi che rimuovi dal dom. Quindi, quando rimuovi elementi dal Dom e desideri rimuovere anche quelle regole di convalida, chiama:
$.validator.unobtrusive.unparseContent('input.something');
