Mengambil dari solusi Xhalent yang ditandai sebagai jawaban di atas, saya memperluasnya sedikit.
$.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];
}
}
}
}
Jadi pada dasarnya ini masih berfungsi sama dengan solusi Xhalent di atas tetapi saya menambahkan kemampuan untuk menghapus aturan untuk elemen yang Anda hapus dari dom. Jadi, ketika Anda menghapus elemen dari Dom dan Anda ingin aturan validasi tersebut dihapus juga, panggil:
$.validator.unobtrusive.unparseContent('input.something');
