TLDR version: I have a custom jquery validation the returns the correct values but the rule is not getting enforced.
I have a custom validation rule that looks like this:
$.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');
});
});
This validation calls a PHP API that checks if the email's domain name is live, hence correct. This API returns the correct values and the console.log() also reflects the correct values, which is the value I am returning as a boolean. All good so far...
I call this validation rule like this:
validator.validate({
rules: {
email: {
required: true,
email: true,
isDomainValid: true,
},
});
I also have some custom error messages (I think maybe irrelevant) like the following:
messages: {
email: {
required: "The Email Address cannot be empty",
isDomainValid: "Please correct the Email Address after the # character",
email: "Invalid Email Address format",
}, },
All my validations, including one other custom validation work flawlessly except this one. Here is all the code I am running in case someone wants to see the whole thing. Again, all validations work except the custom isDomainValid validation.
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');
});
});
validator.validate({

Any help will be greatly appreciated.
I think you're running into a problem where the return value for the success callback function is lost in the $.get method. In my experience I've had to trigger errors manually as part of the callback when checking against the server in a similar way.
Alternatively, I was digging around and found some jQuery Validation documentation that seems like it would make what you are trying to do a little easier: https://jqueryvalidation.org/remote-method/
Try updating the rules.email properties, replacing isDomainValid:
rules: {
email: {
required: true,
email: true,
remote: {
url: function() {
var value = $("[name='email']").val();
var domain = value.split("#");
return "/api/validate-domain/" + domain[1];
},
}
},
You can remove the call to $.validator.addMethod that registers the "isDomainValid" method.
Also, don't forget to update isDomainValid elsewhere, replacing it with remote so the messages are correct.
messages: {
email: {
required: "The Email Address cannot be empty",
email: "Invalid Email Address format",
remote: "Please correct the Email Address after the # character",
},
I am trying to create a validation plugin for web application which evaluates the form when only the form-id is passed to the plugin using javascript/jquery
This is the code i have written where i have used the name of each field to evaluate the input for the html page
$(document).ready(function () {
$('#formId').validate({
rules: {
'Name': {
required: true,
minlength: 3
},
'Email': {
required: true,
minlength: 5
},
'password': "required",
'Confirm_password': {
required : true,
equalTo: "#password"
},
'test': {
required: true
},
'Radio': { required: true },
'ddl': {
required: {
depends: function (element) {
if ('none' == $('#select_field').val()) {
$('#select_field').val('');
}
return true;
}
}
}
},
messages: {
'Name': {
required: "Enter the name",
minlength: "The name should be atleast of 3 characters "
},
'Email': {
required: "Enter the emailid",
minlength: "The emailid should be atleast of 5 characters"
},
'test': {
required: "Check atleast one box"
},
'Radio':
{
required:"Please select an option<br/>"
},
'ddl':
{
required: "Please select an option from the list"
}
},
submitHandler: function (form) {
alert('valid form submitted');
return false;
}
});
});
Use the Jquery Validation plugin.
Read this
I have the JQuery validations below that just ensure that something is written within the input fields, I also have maxlength in the html.
However, I was hoping someone could shed some light on the situation and inform me on how I can add some type of minlength to the jquery code below so I don't require to do any additional functions?
$('#form1').submit(function (e) {
e.preventDefault();
}).validate({
rules: {
txtusername: {
required: true
},
txtfirstname: {
required: true
},
txtemail: {
required: true
},
txtpassword: {
required: true
},
passwordconfirm: {
required: true
}
},
messages: {
txtusername: {
required: "Please enter your Username."
},
txtfirstname: {
required: "Please enter your First Name."
},
txtemail: {
required: "Please enter your Email."
},
txtpassword: {
required: "Please enter your Password."
},
passwordconfirm: {
required: "Please enter your password again."
}
},
errorPlacement: function (error, element) {
error.appendTo(element.parent().prev());
},
submitHandler: function (form, user) {
CheckUser(form);
return false;
}
});
Example HTML -
<div data-role="fieldcontainer">
<label for="txtusername" data-theme="d">Username:</label>
<input type="text" id="txtusername" name="txtusername" maxlength="12" placeholder="Enter Username"/>
</div>
You can use like below:
rules:{
txtusername: {
required: true,
minlength: 3
},
}
I want to validate my form using validate.js and match the password. I wrote the following code:
$(document).ready(function () {
$("#signup-form").validate({
rules: {
"signup-username": {
required: true,
minlength: 2
},
"signup-firstname": {
required: true,
minlength: 2
},
"signup-lastname": {
required: true,
minlength: 2
},
"signup-email": {
required: true
},
"signup-password1": {
required: true,
minlength: 5
},
"signup-password2": {
equalTo: "#signup-password1"
}
},
messages: {
"signup-username": {
required: "Please, enter a user name",
minlength: "Minimum userlength should be 2"
},
"signup-firstname": {
required: "Please, enter your first name",
minlength: "Minimum firstname length should be 2"
},
"signup-lastname": {
required: "Please, enter your last name",
minlength: "Minimum lastname length should be 2"
},
"signup-email": {
required: "Please, enter a valid email"
},
"signup-password1": {
required: "Please, enter your password",
minlength: "Minimum password length should be 5"
},
"signup-password1":"Password doesn't match."
}
submitHandler: function (form)
{
alert("form is submitted successfully.");
}
});
});
I am new to js. Why is it not working. Sometimes I wonder where to put comma and where not. Please help me.
Try change:
"signup-password2": {
equalTo: "#signup-password2"
}
...
"signup-password1":"Password doesn't match."
to:
"signup-password2": {
required: true,
equalTo: "#signup-password1"
}
...
"signup-password2": {
required: "Please, enter your password again",
equalTo: "Password doesn't match."
}
Doc
jsfiddle- validate plugin is broken
another fiddle - works correct
not familiar at all with this library, but I think you mean to check whether signup-password2 is equal to signup-password1. So it should read like:
"signup-password2": {
equalTo: "#signup-password1"
}
My form is using jquery validation. However, the validation is not firing. I am sure it is just a tiny mistake somewhere.. anyone?
Here is fiddle link http://jsfiddle.net/2L6xT/
BAsically here is my jquery validation code
$(document).ready(function () {
<!-- validation -->
$('#submitDetails').validate({
// 1. validation rules.
rules: {
firstName: {
required: true,
maxlength: 120
},
lastName:{
required: true,
maxlength: 120
},
custom1: {
required: true,
maxlength: 120
},
state: {
required: true
},
custom9: {
required: true
},
email: {
required: true,
email: true
}
},
// 2. Validation fail messages
messages: {
custom9: {
required: "You must agree to the terms of conditions in order to participate."
}
},
errorPlacement: function(error, element) {
if (element.attr("name") == "custom9" )
error.appendTo("#error_msg");
else
error.insertAfter(element);
}
});
///execute when submit button is clicked
$("#submit").click(function () {
});
});
In your html, the input element doesnot have name, the validator framework uses name to apply the rules
<input type="text" class="form-control" id="firstName" name="firstName" placeholder="First name" />
so along with id add name also(id is not required if it is not used elsewhere)
