我想在jquery验证引擎中验证keyup事件的电子邮件文本字段。（仅限电子邮件文本字段）。如何在jquery验证引擎中完成？
这是 html：
<input type="text" name="email" id="email" class="validate[required,custom[email]]" />
这是JS：
(function($){
$.fn.validationEngineLanguage = function(){
};
$.validationEngineLanguage = {
newLang: function(){
$.validationEngineLanguage.allRules = {
"required": { // Add your regex rules here, you can take telephone as an example
"regex": "none",

$.validationEngineLanguage.newLang();
})
(jQuery);
还有其他字段，例如国家/地区下拉列表等，但我想在 keyup 事件上绑定电子邮件文本字段。 其他人应该以默认方法行事
通读 jQuery 验证引擎文档，您可以通过执行以下操作来验证字段：
$("#emailInput").validationEngine('validate');
为了在每次添加新字符时检查它，您可以执行以下操作：
$("#emailInput").on('keyup', function() {
$(this).validationEngine('validate');
});
