我正在Liferay 7.3.5中开发一个表单。表单的目的是在将数据AJAX发送到资源之前验证数据。
代码运行良好，问题是在通过AJAX发送数据之前，我找不到验证表单字段的解决方案。AJAX代码片段如下
//Evento boton de formulario
$('#<portlet:namespace/>button-contactForm').click(function(){
var form = $('#<portlet:namespace/>fm')[0];
var data = new FormData(form);
$.ajax({
type: "POST",
//enctype: 'multipart/form-data',
url: '${emailResourceURL}',
data: data,
processData: false,
contentType: false,
cache: false,
timeout: 600000
}).done(function( data, textStatus, jqXHR ) {
$('#<portlet:namespace/>fm').trigger('reset');
console.log("La solicitud se ha completado correctamente." );
}).fail(function( jqXHR, textStatus, errorThrown ) {
console.log("La solicitud ha fallado: " + textStatus);
});
});
在这种情况下，如何验证表单字段？我在下面向您展示了完整的代码。
<%@ include file="/init.jsp" %>
<portlet:resourceURL id="email" var="emailResourceURL"/>
<portlet:resourceURL id="captcha" var="captchaResourceURL"/>

谢谢！
问候！
您可以在ajax调用之前使用js验证表单。将您的ajax代码片段修改为此
//Evento boton de formulario
$('#<portlet:namespace/>button-contactForm').click(function(){
// get your form validator
var formValidator = Liferay.Form.get('<portlet:namespace />fm').formValidator;
// manually validates the form
formValidator.validate();
// verify if there are errors. If so, returns nothing
if (formValidator.hasErrors()) return;
var form = $('#<portlet:namespace/>fm')[0];
var data = new FormData(form);
$.ajax({
type: "POST",
enctype: 'multipart/form-data',
url: '${emailResourceURL}',
data: data,
processData: false,
contentType: false,
cache: false,
timeout: 600000
}).done(function( data, textStatus, jqXHR ) {
$('#<portlet:namespace/>fm').trigger('reset');
console.log("La solicitud se ha completado correctamente.");
}).fail(function( jqXHR, textStatus, errorThrown ) {
console.log("La solicitud ha fallado: " + textStatus);
});
});
