While click the button form submit will trigger, it's reload the page. So give onsubmit="return false" to form for prevent the page load.
Like below code
<form onsubmit="return false">
</form>
Hope this will help you.
1st: what that line expect to do?? email.password.focus(); it will give you an error .. so you can use
if(email=="" || password=="")
{
alert("Every Field Is Requird");
if(email == ""){
email.focus();
}
// check the same way for password
}
else......
2nd: better to don't mix jquery with pure javascript
3rd in your function it submit a form before prevent the page from reloading so you can use
in html
<form onsubmit="login();"> // instead of the submit input click event
and your function
function login()
{
var email=$('#email').val();
var password=$("#pass").val();
var pattern = /^[a-zA-Z0-9\-_]+(\.[a-zA-Z0-9\-_]+)*#[a-z0-9]+(\-[a-z0-9]+)*(\.[a-z0-9]+(\-[a-z0-9]+)*)*\.[a-z]{2,4}$/;
if(email=="" || password=="")
{
alert("Every Field Is Requird");
//email.password.focus();
}
else
{
//alert("hii");
$.post('custom-look/loginvalidate.php',{uemail:email,upass:password}, //email,pass ->textbox name
function(data)
{
$('#result').html(data);
});
}
return false;
}
or you can use e.preventDefault();
<form onsubmit="login(e);"> // instead of the submit input click event
and your function
function login(e)
{
e.preventDefault();
var email=$('#email').val();
var password=$("#pass").val();
var pattern = /^[a-zA-Z0-9\-_]+(\.[a-zA-Z0-9\-_]+)*#[a-z0-9]+(\-[a-z0-9]+)*(\.[a-z0-9]+(\-[a-z0-9]+)*)*\.[a-z]{2,4}$/;
if(email=="" || password=="")
{
alert("Every Field Is Requird");
//email.password.focus();
}
else
{
//alert("hii");
$.post('custom-look/loginvalidate.php',{uemail:email,upass:password}, //email,pass ->textbox name
function(data)
{
$('#result').html(data);
});
}
//return false;
}

Today I am going to use JavaScript to do a validation of the registration page, but after an afternoon of verification, the function can be called. When the test pop-up window is added at the beginning of the function, the pop-up window pops up correctly, but the verification function in the function is always unresponsive. Ask for the forum's amnesty, where is the problem, thank you! ! !
I added a test popup statement to the script and it succeeded. But other functions don't respond.

You can just add onsubmit=return Klikni(); attribute to your form and return false; to Klikni function without using .keypress(). Form submitted on user pressing enter is a default behaviour.
function Klikni(e) {
alert("Enter pressed");
return false;
}
<form name="forma1" action="#" id="forma1" onsubmit="return Klikni();">
Put your cursor into the field and press Enter.<br>
<input type="text">
</form>
try like this source,
form.submit(function(e) {
e.preventDefault();
$(this).find('[type=submit]').click();
$("form").submit();
})
Try keydown instead of keypress as:
$("forma1").keydown(function(event) {
You may use like this.It should be like this Klikni(); not like event.Klikni();
<script>
$("forma1").keypress(function(event) {
if (event.which == 13) {
Klikni(); //no need of event there..
}}
</script>
So I made a simple javascript form validator which creates a box with the error message using DOM. But I can't figure out a way how to reset all these changes when i reset the form using
<button type="reset">
I would like to know how it's done please.
Thanks.
The Code
<html>
<head>
<script type="text/javascript">
function validate(){
var fname = document.getElementById("fname");
var surname = document.getElementById("surname");
if(fname.value === "" || fname.value === null){
document.getElementById("sbody").style.display = "block";
document.getElementById("fname").style.display = "block";
return false;
}
//Verify Last Name
if(surname.value === "" || surname.value === null){
document.getElementById("sbody").style.display = "block";
document.getElementById("surname").style.display = "block";
return false;
}
}//End Validate Function
</script>
<style type="text/css">
#sbody{
width: 100px;
height: 100px;
background-color: #f3f3f3;
display:none;
}
.vis{
display: none;
font-size: 12px;
}
</style>
</head>
<body>
<section id="sbody">
<span id="fner" class="vis">First Name is missing.</span>
<span id="lner" class="vis">Surame is missing.</span>
</section>
<form id="registerForm" method="POST" action="register.php" onsubmit="return validate()">
<label for="fname" class="labelStyle">First Name: </label>
<input id="fname" name="fname" type="text" value="">
<label for="surname" class="labelStyle">Surname: </label>
<input id="surname" name="surname" type="text" value="">
<button type="submit">Sign Up</button>
<button type="reset">Reset</button>
</form>
</body>
</html>
The browser cannot magically figure out what has to be done to reset the custom changes.
However you can listen to the reset event of the form using element.addEventListener.
DEMO
HTML
<form id="test">
<div id="errors-ct">The form has errors</div>
<button type="reset">Reset</button>
</form>
JS
//wait for the DOM to be ready
document.addEventListener('DOMContentLoaded', function () {
//store a reference to the errors container div
var errorsCt = document.getElementById('errors-ct');
//listen to the reset event of the form
document.getElementById('test').addEventListener('reset', function (e) {
var form = e.target; //this is how you could access the form
//hide the errors container
errorsCt.style.display = 'none';
});
});
If you want to reset the form, as if user hadn't made any selections or added any input, then just set all form element values to their default value, or empty.
jsFiddle
<div>
<form action="/echo/html" method="get">
<input type="text" placeholder="username" />
<br/>
<input type="password" placeholder="password" />
<br/>
<input type="checkbox" value="test" data-default="checked" checked="checked"/>
<br/>
<button type="reset" value="reset" onclick="resetForm()">reset</button>
<br/>
</form>
<div id="err">Some error message</div>
</div>
window.resetForm = function () {
var fields = $('input'),
uname, pass, check;
uname = $(fields.get(0));
pass = $(fields.get(1));
check = $(fields.get(2));
$("#err").text("");
uname.val('');
pass.val('');
if (check.attr("data-default") == "checked") {
check.attr("checked", "checked");
} else {
check.removeAttr("checked");
}
}
I am working on a login form on which I have added "placeholders" with Mootools OverText
(* http://mootools.net/docs/more/Forms/OverText , http://mootools.net/demos/?demo=Enhanced-Form ).
The problem is that the browsers is autocompleting the fields with email/password and they are showing under the OverText.
Is there any way I can make the overtext not show when the fields are filled by the browser? (*I would like to keep the autocomplete ON)
*When the browser is autocompleting the fields the OverText is showing over the email/password:
**Normal view of the fields with OverText:
<form id="user_form_login" action="/login">
<div id="email-wrapper" class="form-wrapper">
<div id="email-element" class="form-element">
<input type="email" name="email" id="email" value="" tabindex="1" class="text" autocomplete="off" title="<?php echo $this->translate('Email Address'); ?>">
</div>
</div>
<div id="password-wrapper" class="form-wrapper">
<div id="password-element" class="form-element">
<input type="password" name="password" id="password" value="" tabindex="2" title="<?php echo $this->translate('Password'); ?>">
</div>
</div>
</form>
<script type="text/javascript">
window.addEvent('domready', function(){
var LoginForm = $('user_form_login');
LoginForm.getElements('[type=email], [type=password]').each(function(el){
new OverText(el);
});
});
</script>
Try this:
<script type="text/javascript">
window.addEvent('domready', function(){
var LoginForm = $('user_form_login');
LoginForm.getElements('[type=email], [type=password]').each(function(el){
new OverText(el);
});
// *** New part ***
LoginForm.getElements('[type=email], [type=password]').addEvent('change', function () {
this.getNext('label').set('text', '');
});
});
</script>
EDIT:
(Another alternative since its difficult to detect auto-fill)
var All_El = LoginForm.getElements('[type=email], [type=password]');
var re_check = setInterval(function () {
All_El.each(function (el) {
if (el.value != '') {
el.getNext('label').set('text', '');
}
});
}, 400);
Here is the sample code for my project. It contains two forms on a single page.
The first form contains username and a textbox, when I enter the username and click the login button the user's name should be displayed and the logout form should be displayed.
How do I ensure that the user will remain logged in once the browser window is closed?
Code

<script>
function set(x)
{
document.getElementById(x).value="";

}

If you plan to use spring, spring-security provides remember me services which would let you be logged in across browsers or sessions.
Other option is to use Apache shiro if you find spring-security too complex for your application.
