First, I have a script for validation, its working fine and if I added a script for the alert box, validation function is not working. What I need is first, the validator should execute and after that, the alert for the button should execute.
<script>
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$( "#ContactForm1" ).validate({
rules: {
fname: "required",
lname: "required",
phone: "required",
email: {
required: true,
email: true
},
message: "required",
}
});
</script>
<script>
$(document).ready(function(){
$("#btn").click(function(){
alert("Hello World!");
});
});
</script>
Use submitHandler:
$("#ContactForm1").validate({
rules: {
fname: "required",
lname: "required",
phone: "required",
email: {
required: true,
email: true
},
message: "required",
},
submitHandler: function() {
alert("Hello World!");
}
});
Here is working example.
To check if your form is valid simply use:
if ($( "#ContactForm1" ).valid())
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$( "#ContactForm1" ).validate({
rules: {
fname: "required",
lname: "required",
phone: "required",
email: {
required: true,
email: true
},
message: "required",
},
submitHandler: function() {
//$('#btn').click();
}}
);
src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js">
$(document).ready(function(){
$("#btn").click(function(){
if ($( "#ContactForm1" ).valid()) {
alert('runs only if form is valid');
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.16.0/jquery.validate.js"></script>
<form id="ContactForm1" method="get" action="">

I have just implemented input field validations e.g. "Please enter your name" if an input field is left empty.
I done this through JQuery mobile, however the issue I am not having is that when the user submits (registerUser(); ) the form the validations do not occur (if left empty) in time and instead the data is submitted into the database.
How can I prevent the page from loading and parsing the data into the database if there are empty fields?
HTML -
<form id="form1">
<div data-role="fieldcontainer">
<label for="txtusername" data-theme="d">Username:</label>
<input type="text" id="txtusername" name="txtusername" data-theme="d" placeholder="Enter Username"/>
</div>
<div data-role="fieldcontainer">
<label for="txtfirstname" data-theme="d">First Name:</label>
<input type="text" id="txtfirstname" name="txtfirstname" data-theme="d" placeholder="Enter First Name"/>
</div>
<div data-role="fieldcontainer">
<label for="txtlastname" data-theme="d">Last Name:</label>
<input type="text" id="txtlastname" name="txtlastname" data-theme="d" placeholder="Enter Last Name"/>
</div>
<div data-role="fieldcontainer">
<label for="txtemail" data-theme="d">Email:</label>
<input type="email" id="txtemail" name="txtemail" data-theme="d" placeholder="Enter Enter Email"/>

JavaScript File (JQuery Mobile) -
$('#form1').validate({
rules: {

return false;
}
});

function registerUser() {
var Username = document.getElementById("txtusername").value;
var Firstname = document.getElementById("txtfirstname").value;
var Lastname = document.getElementById("txtlastname").value;
var Email = document.getElementById("txtemail").value;
var Password = document.getElementById("txtpassword").value;
var Confirmpass = document.getElementById("passwordconfirm").value;
db = window.openDatabase("SoccerEarth", "2.0", "SoccerEarthDB", 2*1024*1024);
db.transaction(function(tx) {
NewUser(tx, Username, Firstname, Lastname, Email, Password, Confirmpass);
}, errorRegistration, successRegistration);
}
function NewUser(tx, Username, Firstname, Lastname, Email, Password, Confirmpass) {
var _Query = ("INSERT INTO SoccerEarth(UserName, FirstName, LastName, Email, Password, CPass) values ('"+ Username +"','"+ Firstname +"','"+ Lastname +"','"+ Email +"', '"+ Password +"', '"+ Confirmpass +"')");
alert(_Query);
tx.executeSql(_Query);
}
function errorRegistration(error) {
navigator.notification.alert(error, null, "Got an error mate", "cool");
}
function successRegistration() {
navigator.notification.alert("User data has been registered", null, "Information", "ok");
$( ":mobile-pagecontainer" ).pagecontainer( "change", "#page4" );
}
I removed onclick="return registerUser(); return false;" from the input button and placed it in the submitHandler.
To prevent the form submission i added .
$('#form1').submit(function(e) {
e.preventDefault();
})
$(document).ready(function () {
function registerUser(form) {
var formdata = $(form).serializeArray()
console.log(formdata);
}
$('#form1').submit(function (e) {
e.preventDefault();
}).validate({
rules: {
txtusername: {
required: true

txtfirstname: {
required: true

I am doing my form validation with jquery validation plugin. Everything seems fine but its not working. No message appears. Or may be its due to files that I have included.

When using any jQuery plugin, you must load jQuery first. You are also including the plugin twice. You must not include each plugin more than once... preferably use the latest version.
This is correct...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
Otherwise, use the latest plugin version supported by your version of jQuery...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.13.1/jquery.validate.js"></script>

},
}
});
});

Trailing commas (,) are illegal in JavaScript. When you do something like this:
rules: {
firstname: 'required',
lastname: 'required',
}
the JavaScript engine will think that }, is the next item in the rules object.
You need to do something like this:
rules: {
firstname: 'required',
lastname: 'required' // <-- no comma at end
}
I am trying to call JavaScript function while submitting the form.
Here is code but while submitting function not called, please suggest something and I want to show error messages using javascript method as well , how can I show error messages in validation using JavaScript.
<form id="register" name="register" onsubmit="validateForm()">
<label for="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password"><br><br>
<label for="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email"> Email </label><br>
<input type="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit">Submit</button>
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.8/jquery.validate.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
},
"email": {
required: true,
}
}
});
});
</script>
and here is JavaScript code
function validateForm()
{
var password = document.forms["register"]["Password"].value;
var con-password = document.forms["register"]["Confirm-Password"].value;
if(password != con-password)
{
document.getElementById('password-error').style.visibility='visible';
alert("not matched");
}
alert("matched");
}
This is probably due to a syntax error in your script. When you see errors like that, look into the JavaScript console of your browser.
In this case, con-password is not a valid variable name. What JavaScript sees is:
var con - password ...
i.e. the code says "substract password from con". Try an underscore instead:
var con_password ...
Do not need to do anything extra for password matching, just add equalTo: "#Password" to it as shown in the below example:
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"
},
"email": {
required: true,
}
},
messages: {
Password: {
required: "Please provide a password",
minlength: "Your password must be at least 5 characters long"
},
Confirm-Password: {
required: "Please provide a confirm password",
equalTo: "Please enter the same password as above"
}
},
submitHandler: function(form) {
// Your function call
return false; // return true will submit form
}
});
});
Working example:
<form id="register" name="register" action="" method="post">
<label for="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password"><br><br>
<label for="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm_Password" name="Confirm_Password" placeholder="Confirm Password" ><br><br>
<label for="email"> Email </label><br>
<input type="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit">Submit</button>
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.8/jquery.validate.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#register").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5

"Confirm_Password": {

"email": {

messages: {

Confirm_Password: {

equalTo: "Please enter the same password as above"
}
},
submitHandler: function(form) {
// Your function call
return false; // return true will submit form
}
});
});
</script>
Maybe instead of checking if passwords matches you can add new rule in validation?
something like:
... "Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"} ....
and for messages add:
... messages: {
"Password": "Your message",
}...
and all in all something like this: `
$(document).ready(function () {
$("Your form name").validate({
rules: {
"Username": {
required: true,
},
"Password": {
required: true,
minlength: 5
},
"Confirm-Password": {
required: true,
equalTo: "#Password"
},
"email": {
required: true,
email: true
}
}
messages: {
"Password": "Your message",
"email": "Your Message",
},
submitHandler: function (form) {
form.submit();
}
});
});`
try this. i add onclick event on the submit button to call the function validateForm()
html
<form id="register" name="register">
<label for ="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for ="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password" ><br><br>
<label for ="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email" > Email </label><br>
<input type ="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit" onclick="validateForm()">Submit</button>
</form>
this is the validateForm()
<script type="text/javascript">
function validateForm() {
var username = $('#Username'),
password = $('#Password'),
confirm = $('#Confirm-Password'),
email = $('#email');
$('#register').submit(function(ev){
// check if all fields is not empty
if(username.val() === '' || password.val() === '' || confirm.val() === '' || email.val() === '') {
ev.preventDefault(); // prevent form submit
alert('All fields are required.'); //alert message
//check if password and confirm password is equal
} else if(password.val() != confirm.val()){
ev.preventDefault(); // prevent form submit
alert('password did not match.'); //alert message
} else {
return true; // submit form if validation has passed.
}
});
}
</script>
May be you missed - you need to use method="post" in
http://jsfiddle.net/dLbLS/
<form id="register" name="register" method="post" onsubmit="validateForm();" >
<label for ="Username"> Username </label><br>
<input type="text" class="register-control" id="Username" name="Username" placeholder="Enter Username"> <br><br>
<label for ="Password"> Password </label><br>
<input type="password" class="register-control" id="Password" name="Password" placeholder="Enter Password" ><br><br>
<label for ="Confirm-Password"> Confirm Password </label><br>
<input type="password" class="register-control" id="Confirm-Password" name="Confirm-Password" placeholder="Confirm Password" ><br><br>
<label for="email" > Email </label><br>
<input type ="email" class="register-control" id="email" name="email" placeholder="Enter Valid Email"><br><br>
<button type="submit" >Submit</button>
</form>
Use this code
<input type="button" id="close" value="Submit" onClick="window.location = 'validateForm()'">
