I am using jQuery 1.10.1 with migrate, jQueryUI 1.10.3, jQueryValidate 1.11.1.
Just using a simple form, it has two fields. On submit if values are not provided then a dialog box is displayed with a message.
Issue: In IE 10 When user tries to move (drag) the error message dialog box it just moves down. This only happens when vertical scroll bar is appears in the browser window.
Verified in Chrome 27 it works. Sometimes gives the same issue in Firefox 21 and Opera 12.15.
Note: It works fine with jQuery UI 1.10.2 only issue is there in 1.10.3.

I've a jsp with a form that include another jsp with a div (that's a JQuery dialog) and in the dialog I've a form that I've to validate.
My issue is: I cannot create an inner form opened in a dialog. So when I try to validate it, I get following error: Uncaught TypeError: Cannot read property 'form' of undefined.
See following snippet, please:
<html>
<head>
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
<link href="https://code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css" rel="stylesheet" type="text/css" />
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script src="http://cdn.jsdelivr.net/jquery.validation/1.15.0/jquery.validate.min.js"></script>
</head>
<body>
<form id="extForm">
<div id="myDialog">
<form id="intForm">
<label for="field1">Don't write anything in textbox, just click the button</label>
<input type="text" id="field1" required>
</form>
</div>
</form>
</body>
<script>
$("#myDialog").dialog({
autoOpen: false,
modal: true,
title: "myDialog",
buttons: {
"Click me": function(){
$("#myDialog form").valid();
}
}
});
$("#myDialog").dialog("open");
</script>
</html>
If I remove the external form, it works fine. I can I solve this? Thanks.
Note: I can't remove the external form and I have to validate only the fields inside my dialog.
You are getting that error because when you call $("#myDialog").dialog() function of jQuery, myDialog div loses the form from it's inner html.
Please put html back after dialog and before open dialog functions
e.x.
<script>
$("#myDialog").dialog({
autoOpen: false,
modal: true,
title: "myDialog",
buttons: {
"Click me": function(){
$("#myDialog form").valid();
}
}
});
$("#myDialog").html("<form id='intForm'><label for='field1'>Don\'t write anything in textbox, just click the button</label><input type='text' id='field1' required></form>");
$("#myDialog").dialog("open");
</script>
This code should run fine!
Thank you
I solved wrapping dialog inside a form, using option create:
create: function(){
formDialog = $(this).wrap($('')).parent();
}
This is the result:

<input type="text" id="field1" required>
</div>
</form>
</body>
<script>
var formDialog;
$("#myDialog").dialog({
autoOpen: false,
modal: true,
title: "myDialog",
create: function(){
formDialog = $(this).wrap($('<form>')).parent();
},
buttons: {
"Click me": function(){
formDialog.valid();
}
}
});
$("#myDialog").dialog("open");
</script>
</html>
Thanks to all.
The following code does not drop down and up the div when clicked,It doesn't perform anything.But Im trying the exact code that works here http://jsfiddle.net/vNeXq/
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<script>
$('#login').click(function(){
$('#loginForm').slideToggle('fast');
});
</script>
</head>
<body>
<div id="loginWrapper">
<a id="login">Login</a>
<div id="loginForm">
<form name="login" method="post">
<input type="text" name="username" placeholder="Username" />
<input type="password" />
<input type="submit" value="Login" />
</form>
</div>
</div>
</body>
CSS File
#loginWrapper
{
width:400px;
background-color:#F0F0F0;
}
#login
{
cursor:pointer;
}
#loginForm
{
display:none;
}
Pretty sure you haven't included jQuery. The jQuery library is necessary for the script you want to run. You can download a copy of jQuery from here or you can use a copy hosted from Google. jQuery has to be included before the code you want to run.
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="loginWrapper">
<a id="login">Login</a>
<div id="loginForm">
<form name="login" method="post">
<input type="text" name="username" placeholder="Username" />
<input type="password" />
<input type="submit" value="Login" />
</form>
</div>
</div>
<!-- INCLUDE JQUERY -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#login').click(function(){
$('#loginForm').slideToggle('fast');
});
}):
</script>
</body>
</html>
If you have included jQuery in your project you maybe want to wrap your code with a function that executes when the page is loaded, so you are sure everything is there:
$(document).ready(function(){
$('#login').click(function(){
$('#loginForm').slideToggle('fast');
});
})
You can try like:
<script>
$(document).ready(function(){
$(document).on('click','#login',function(){
$('#loginForm').slideToggle('fast');
});
});
</script>
It seems that are your not including the jQuery library in the head of the html file.
Include the jquery library (it should be before your script):
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
In order for jQuery to modify the html document it must wait until the page is ready. You can do this by putting your function into:
$(document).ready(function() {
// your code here
});
So your script will end up looking like:
$(document).ready(function() {
$('#login').click(function(){
$('#loginForm').slideToggle('fast');
});
});
I'm developing a website through Parse.com JavaScript. I'm working on the login page and I found this nice template: http://designscrazed.org/css-html-login-form-templates/
However, when I try to modify the submit part of this page to be processed through Parse.com, the page auto-refreshes before the Parse.com transaction could be made. I know the JavaScript file is properly referenced though.

$(document).ready(function() {
alert('hello');
Parse.$ = jQuery;

});
// called when the user clicks the log in button
$('#prindle_log_on').on("click",function(e) {

alert('user found');
},
error: function(user, error)
{

alert('log in failed');
}

I never get the balloon saying "form has been submitted." Help?

</div>
$(document).ready(function () {
$('#prindle_log_on').on("click", function (e) {

Place the click handler inside $(document).ready because $('#prindle_log_on') will not be found until the body has rendered.

I create a login form in popup box. When the username field is left blank, an error message will appear to notify the user to fill in the empty username field. As a test, I click on the login button leaving the username field, and the message appears in the popup box as expected. But the problem is the popup box is closed immediately.
So, my question is how do I keep the popup box open with the error message shown?
Here is my script:
<!doctype html>
<html lang="en-US">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
<title>Modal Login Window Demo</title>
<link rel="shortcut icon" href="http://designshack.net/favicon.ico">

<script type="text/javascript" charset="utf-8" src="http://designshack.net/tutorialexamples/modal-login-jquery/js/jquery.leanModal.min.js"></script>
</head>
<body>
<div id="w">
<div id="content">
<center><a href="#loginmodal" class="flatbtn" id="modaltrigger">Modal Login</a</center>
</div>
</div>
<div id="loginmodal" style="display:none;">
<?php
if($_POST["loginbtn"]){
if(!$_POST["username"]){
echo "<center><font color=red>please fill your username</font></center>";
}elseif(!$_POST["password"]){
echo "<center><font color=red>please fill your password</font></center>";
}
}
?>
<h1>User Login</h1>
<form method="post">
<label for="username">Username:</label>
<input type="text" name="username" id="username" class="txtfield" tabindex="1">
<label for="password">Password:</label>
<input type="password" name="password" id="password" class="txtfield" tabindex="2">
<div class="center"><input type="submit" name="loginbtn" id="loginbtn" class="flatbtn-blu hidemodal" value="Log In" tabindex="3"></div>
</form>
</div>
<script type="text/javascript">
$(function(){
$('#loginform').submit(function(e){
return false;
});
$('#modaltrigger').leanModal({ top: 110, overlay: 0.45, closeButton: ".hidemodal" });
});
</script>
</body>
</html>
The closeButton option will always cause the modal to be closed when the corresponding button is clicked. And looking at the leanModal source, there doesn't seem to be any direct way to manipulate its event-handling callback.
So if all you want to do is to keep the form modal opened if the fields are not filled, and let your server-side codes perform the validation you can just do the following:
$('#loginform').submit(function(e){
if(!$('#username').val()) {
$('#loginmodal').show();
}
else
console.log("Enter your username");
return false;
});
Live demo on jsfiddle. Notice that I added an id to the form tag, and fixed some of the malformed HTML tags in the fiddle.
Haven't had a chance to test but try stopping the propagation of the click function, doing that tells the browser to not complete the default action for this event.
$('#loginbtn').click(function(e){
if(!$('#username').val()){
e.stopPropagation();
}
});
or as the other answer suggests try using jquery validation which will help in getting all this to work much more easily I like to use: http://jqueryvalidation.org/
This appears to be very similar to this question: How to force a html5 form validation without submitting it via jQuery
That answer assumes that you would be adding the required attribute to the necessary form elements, and also that you use a polyfill such as html5shiv if old browser support is a requirement.
use jquery validationEngine. It is a good one for your requirement.
See demo here
You have some missing information in the sample html, the form ID is missing therefor jQuery will not attach to it.
I handle this situation by using AJAX for the form action with a json response.
Here is an example from one of my recent apps... Notice the event.preventDefault() method to keep the form from submitting.
$(function () {
jQuery('body').on('submit', '#frmlOGIN', function (event) {
event.preventDefault();
jQuery.post("?action=ajax_signup", jQuery("#frmlOGIN").serialize(), function (data) {
if (data.status == "OK") {
jQuery("#modal_content").html(data.content);
} else {
jQuery("#error_message").html(data.response);
}
});
});
$('#modaltrigger').leanModal({
top: 110,
overlay: 0.45,
closeButton: ".hidemodal"
});
});
Here is a jsfiddle example.
http://jsfiddle.net/LqmzwwL3/
Assume the following simple HTML:
<html>
<head><title>Test</title>
<script src="js/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="js/jquery-ui-1.10.3.custom.min.js" type="text/javascript"></script>
<link href="css/jquery-ui-1.10.3.custom.min.css" rel="stylesheet" type="text/css" />
</head>
<body>
<href="#" id="doExport">Export Now</a>
<div id="exportPopup">
<p>From: <input type="text" id="dateFrom" /></p>
<p>To: <input type="text" id="dateTo" /></p>
</div>
</body>
</html>
Now also assume that there is CSS that styles #exportPopup appropriiately and sets it to display:none initially. This brings me to two questions:
How do I make that hidden DIV (#exportPopup) show up right where the #doExport link is clicked?
How do I use the JQuery datepicker on those two input boxes?
For Question 2 I have already tried this:
$(document).ready(function (e) {
$("#dateFrom").datepicker();
$("#dateTo").datepicker();
});
and it just doesn't work when I click those boxes. I hope someone can enlighten me.
I have created a rough model at http://jsfiddle.net/santoshjoshi/32enE/1/
so basically used the jQuery dialog plugin you need to add following code open the dialog box
HTML Code
Export Now
<div id="exportPopup" style='display:none'>
<p>From: <input type="text" id="dateFrom" /></p>
<p>To: <input type="text" id="dateTo" /></p>
</div>
JavaScript Code
$(document).ready(function (e) {
$("#dateFrom").datepicker();
$("#dateTo").datepicker();
});
$( "#doExport" ).click(function() {
$( "#exportPopup" ).dialog( );
});
also please have a look at jQuery dialog documentation to customize your popup/dialog
