【问题描述】：
TLDR 版本：我有一个自定义 jquery 验证，它返回正确的值，但规则没有得到执行。
我有一个如下所示的自定义验证规则：
$.validator.addMethod("isDomainValid", function(value, element) {
var domain = value.split("@");
$.get('/api/validate-domain/' + domain[1], function(data, status) {
domain = JSON.parse(data);
console.log(domain['status'] === 'valid');
return (domain['status'] === 'valid');
});
});
此验证调用一个 PHP API 来检查电子邮件的域名是否有效，因此是正确的。此 API 返回正确的值，并且 console.log() 也反映了正确的值，这是我作为布尔值返回的值。到目前为止一切顺利...
我这样称呼这个验证规则：
validator.validate({
rules: {
email: {
required: true,
email: true,
isDomainValid: true,
},
});
我还有一些自定义错误消息（我认为可能无关紧要），如下所示：
messages: {
email: {
required: "The Email Address cannot be empty",
isDomainValid: "Please correct the Email Address after the @ character",
email: "Invalid Email Address format",
}, },
我所有的验证，包括另一个自定义验证，除了这个之外都完美无缺。这是我正在运行的所有代码，以防有人想查看整个内容。同样，除了自定义 isDomainValid 验证之外，所有验证都有效。
var validator = $('#checkout_form');
$.validator.addMethod("checkPoBox", function(value, element) {
let cleansedValue = $.trim(value.toLowerCase()).replace(/[^a-zA-Z]+/g, '');
let checked = $('#ship-box').prop('checked') ? true : false;
if (/pobox/i.test(cleansedValue) && checked && element.name == 'shipping_address') {
return false;
}
if (/pobox/i.test(cleansedValue) && !checked && element.name == 'billing_address') {
return false;
}
return true;
});
$.validator.addMethod("isDomainValid", function(value, element) {
var domain = value.split("@");
$.get('/api/validate-domain/' + domain[1], function(data, status) {
domain = JSON.parse(data);
console.log(domain['status'] === 'valid');
return (domain['status'] === 'valid');
});
});
