Jquery validation not check it is true or not while key pressing. It triggered after focus out from the element. After focus out done validation check start while key pressing. Why is this? here has my code
$('input[name=roleName]').keypress(function () {
$('form').validate({
rules: {
roleName: {
required: true,
isRoleUsed: true
}
},
messages: {
roleName: {
required: "You have to enter role name"
}
}
});
});
The .validate() method never goes inside of a keypress event handler. It's only the initialization method of the plugin and only goes inside of a DOM ready event handler.
Then the keyup event is captured automatically once the plugin is initialized.
$(document).ready(function() {
$('form').validate({
rules: {
roleName: {
required: true,
isRoleUsed: true
}
},
messages: {
roleName: {
required: "You have to enter role name"
}
}
});
});

Note, by default, validation is "Lazy", meaning that you get one attempt to fill out the form before the required validation rules are evaluated. The keyup events are not captured until after the first click of the submit button.
Otherwise, you can change the keyup behavior to "Eager" validation by over-riding the onkeyup option.
$(document).ready(function() {
$('form').validate({
onkeyup: function(element) {
this.element(element);
},
rules: {
roleName: {
required: true,
isRoleUsed: true
}
},
messages: {
roleName: {
required: "You have to enter role name"
}
}
});
});

I have a form on which I am using jquery.validate. I initially call validate with a set of rules and custom messages...
$("#formName").validate( {
rules: {
myExistingInput: {
required: true
}
},
messages: {
myExistingInput: {
required: "Enter something"
}
},
ignore: null, // include hidden fields (see below)
submitHandler: function(form) {
// do stuff
},
invalidHandler: function(event, validator) {
// do stuff (some of the fields may have been hidden by a collapsible panel
// if there is an error on one of those fields, expand the panel so the error
// becomes visible)
}
});
Later, I dynamically add fields to the form, and add rules for those fields too...
$("#formName").append(...);
$("#newInputName").rules("add", {
required: true,
messages: {
required: "Enter something else"
}
});
If I then submit the form, I get an error from within jquery.validate...
Exception occured when checking element newInputName, check the
'messages' method.TypeError: Unable to get property 'call' of
undefined or null reference
Debugging in the browser, I can see the error is being thrown from within the "check" function, and that the "method" variable is set to "messages".
If I remove the messages from the call to rules("add",...
$("#newInputName").rules("add", {
required: true
});
it works as expected, but obviously I now have no custom error messages.
I have seen many examples here on SO indicating that my syntax is correct. Any suggestions?
BTW: jQuery Validation Plugin - v1.11.0 - 2/4/2013
Your code seems to be working, without error, as you posted it.
DEMO with DOM ready: http://jsfiddle.net/UZTnE/
DEMO with PageInit & jQuery Mobile: http://jsfiddle.net/xJ3E2/
$(document).on("pageinit", function () {
$('#myform').validate({ // initialize the plugin
rules: {
field1: {
required: true
}
},
messages: {
field1: {
required: "Enter something"
}
}
});
$('[name*="field"]').each(function () {
$(this).rules('add', {
required: true,
messages: {
required: "Enter something else"
}
});
});
});
HTML:
<form id="myform">
<input type="text" name="field1" />
<input type="text" name="field2" />
<input type="submit" />
</form>
BTW:
this...
ignore: null, // include hidden fields
should be...
ignore: [], // include hidden fields
See: jQuery Validate - Enable validation for hidden fields
$(document).ready(function(){
$("#controlId").rules("add", {
required : true,
messages : { required : 'field is required.' }
});
});
as an answer to this old issue, I do like this to get the meassges inside the rules object.
After you have added the rules you can add messages like this:
var inputRules = $('input').rules();
inputRules.messages = {required: 'your message'};
Good luck!
I'm trying to implement jQuery Validation Plugin v1.19.2 (http://jqueryvalidation.org/), it doesn't trigger automatically at first. It only activates afterI I hit enter or submit the form. Once I have hit enter or submit form then it works on keyup.
Please see following gif to understand what I mean. The first field (title) is required, as you can see that I enter text there, and then delete a few times but it does not show any error. But after I submit, then each time it shows error.
Here's the JSFiddle link: http://jsfiddle.net/ubwq95e8/
$(document).ready(function() {
$("form#signup").validate({
rules: {
title: {
required: true
},
},
});
});
Try to add onkeyup in $("form#signup").validate.
See document: https://jqueryvalidation.org/validate/#onkeyup
onkeyup: function(element) {
$(element).valid();
},
The plugin doesn't validate on onkeyup event by default, you need to implement it as per your requirements. Here's a simple example:
$("form#signup").validate({
onkeyup: function (element, event) {
$(element).valid();
},
rules: {
title: {
required: true
},
},
errorPlacement: function(error, element){}
});
Similarly for other event like onclick, onfocus* etc
just add a custom event for check inputs when focusout
$(document).ready(function() {
$("form#signup").validate({
rules: {
title: {
required: true
},
},
errorPlacement: function(error, element){}
});
$('#signup input').focusout(function(){
var form = $( "#signup" );
form.valid()
})
});
here is new jsfiddle with codes that work for your case
http://jsfiddle.net/qhsj84en/
I'm using some jQuery to do some form validation. The following is the validation script.
$(document).ready(function() {
$('#contact-form').validate({
rules: {
cf_name: {
minlength: 2,
required: true
},
cf_email: {
required: true,
email: true
},
phone: {
minlength: 10,
required: true
},
user_pass: {
minlength: 2,
required: true
},
validateSelect: {
required: true
},
validateCheckbox: {
required: true,
minlength: 2
},
validateRadio: {
required: true
}
},
focusCleanup: false,
highlight: function(label) {
$(label).closest('.control-group').removeClass('success').addClass('error');
},
success: function(label) {
label
//.text('OK!').addClass('valid')
.closest('.control-group').addClass('success');
},
errorPlacement: function(error, element) {
error.appendTo(element.parents('.controls'));
}
});
$('.form').eq(0).find('input').eq(0).focus();
}); // end document.ready
On my submit button, I have this code:
<input type="submit" value="SUBMIT" id="sub" class="sub_text">
I'd like to make it so that when a user clicks the submit button and the form validates before it does any fading/transitioning, that it does within this code:
$("#sub").click(function(){
$("#forms").fadeOut( 1000 );
$("#overlay1").delay(1000).fadeIn( 1000 );
});
But my problem is that if a user forgets a field and then hits submit, the overlay transition happens. I'd like it to only happen when there's a
success of validation.
How am I able to trigger the event only when it's validated?
Have you tried calling form.valid() as follows:
$("#sub").click(function(){
if($('#contact-form').valid()){
$("#forms").fadeOut( 1000 );
$("#overlay1").delay(1000).fadeIn( 1000 );
}
});
.valid() checks whether given form is valid or not.
You are using the wrong hook. You are attaching your fadein code into "click" event of the button, means just when the user clicks the button you will execute the fadein.
Solution? quite simple, just have a look at the jqueryvalidation doc (http://jqueryvalidation.org/validate), instead of fadein in click event of the button, just do it in the validation hook.
$('#contact-form').validate({
submitHandler: function(form) {
$("#forms").fadeOut( 1000 );
$("#overlay1").delay(1000).fadeIn( 1000 );
// do other things for a valid form
form.submit();
}
});
I have a script which validates the inputs entered upon an onmouseout event. Firstly when the user move the cursor away from the first input, the validation occurs and the error message is shown. I want to do the same process with the second input, that is, an error message is shown when the cursor is moved away from the second input. Below is my code:
<script type="text/javascript">
$('document').ready(function () {
$('#Make').on('mouseout', function () {
$("#carform").validate({
rules: {
Make: {
required: true
}
},
messages: {
Make: {
required: "Please enter a make"
}
},
submitHandler: function (form) {
form.submit();
}
});
if ($("#carform").valid()) {
//Do some code
}
});
$('#Model').on('mouseout', function () {
$("#carform").validate({
rules: {
Model: {
required: true
}
},
messages: {
Model: {
required: "Please enter a model"
}
},
submitHandler: function (form) {
form.submit();
}
});
if ($("#carform").valid()) {
//Do some code
}
});
});
</script>
My view:
<div>
<form id="carform" method="post">
<p>
#Html.LabelFor(l=>l.Make)
#Html.TextBoxFor(l => l.Make)
</p>
<p>
#Html.LabelFor(l=>l.Model)
#Html.TextBoxFor(l => l.Model)
</p>
<p>
<input id="createCar" type="submit" value="Submit"/>
</p>
</form>
</div>
When I move my cursor away from the input Make, the error message is seen. But when I do the same with the second input Model, no error message is seen. Any idea where I am doing it wrong?
You just need to initialize it once.. Not on each input blur and you have option in jquery validation which validates on blur which is as below:
onfocusout
Type: Boolean or Function()
Validate elements (except checkboxes/radio buttons) on blur. If
nothing is entered, all rules are skipped, except when the field was
already marked as invalid.
Set to a Function to decide for yourself when to run validation.
A boolean true is not a valid value.
Example: Disables onblur validation.
$(".selector").validate({
onfocusout: false //Do not use false instead use a callback function
});
The callback gets passed two arguments:
element
Type: Element The element currently being validated, as a DOMElement.
event
Type: Event The event object for this focusout event.
So you can make use of callback function as below in your case:
$('document').ready(function () {
$("#carform").validate({
onfocusout: function(element) {
this.element(element);
},
rules: {
Make: {
required: true
},
Model: {
required: true //keep both the required here
}
},
messages: {
Make: {
required: "Please enter a make"
},
Model: {
required: "Please enter a model" //keep both the messages here
}
},
submitHandler: function (form) {
if ($(form).valid()) { //check for valid form here
form.submit()//submit here
}
}
});
$('#Make,#Model').on('blur', function() {
$("#carform").validate().element( this );
});
});
Simple, define a same class for both inputs say class foo
and check mouseout event with class as an identifier like:
$('.foo').on('mouseout', function () {
// your code here
});
I need to put a promotional message either at the bottom of the form or in an alert when a user meets certain criteria. I think an alert might be best. It's to do with certain postcodes so I will need to write a regex (I haven't done this yet). It needs to happen when the user clicks submit and before it goes to the server. I'm not sure how to write this and where it should be placed in my script. This is what I have so far if it helps.
$(document).ready(function(){
$("#orderForm").validate({
onfocusout: function(element) {
this.element(element);
},
rules: {
shipFirstName: {
required: true,
},
shipFamilyName: {
required: true,
},
shipPhoneNumber: {
required: true,
},
shipStreetName: {
required: true,
},
shipCity: {
required: true,
},
billEmailAddress: {
required: true,
},
billPhoneNumber: {
required: true,
},
billCardNumber: {
required: true,
},
billCardType: {
required: true,
},
shipPostalCode: {
postalCode: true,
},
fidelityCardNumber: {
creditCardNumber: true,
},
}, //end of rules
}); // end of validate
}); // end of function
$.validator.addMethod('postalCode',
function (value, element)
{
return this.optional(element) || /^[A-Z]{2}\d{1,2}\s\d{1,2}[A-Z]{2}$/.test(value);
}, 'Please enter a valid Postal Code');
$.validator.addMethod('creditCardNumber',
function(value, element)
{
return this.optional(element) || /^[A-Z]{1}([A-Z]|\d){4}\s?([A-Z]|\d){5}\s?([A-Z]|\d){3}\d{1}(\!|\&|\#|\?){1}$/.test(value);
}, 'Please enter a valid card number');
You should be able to do something like this (this will replace the default submit behavior):
$("#orderForm").validate({
submitHandler: function(form) {
// code to display personal message
// code to handle form submission
},
onfocusout: function(element) {
...
Write a click function for submit button and call ajax function in that
$("#submit").click(function(){
alert("This is a promotional message on submit");
//here write ur ajax code.
});
ajax in Jquery.
You need to provide a submitHandler as an option to the validate method.
submitHandler: function(form) {
if ($("form #hasAsked").val() != 'true' && /[MK]{2}[1-15|17|19|77]{2}/.test($("#shipPostalCode").val()) {
openModalDialog();
return false;
}
return true;
},
...
An a function
function openModalDialog() {
$("<div>Wanna buy?? <button value="yes" id="y/><button value="no" id="n/></div>")
.after("body p:first-child")
.show('slide')
.find("#y, #n").click(function() { $("form #hasAsked").val("true") /* default: false */; })
.end()
.find("#y")
.click(function() { $("form #hiddenbuy").val("true"); })
.end()
.find("#n")
.click(function() { $("form #hiddenbuy").val("false"); })
}
