jQuery Mobile: use a dialog to let user confirm form submission - jquery-mobile

I would like to user the beautiful jQuery Mobile dialog:
Open dialog
To ask a user if he really wants to submit a form.
My idea is: user fills the form then clicks on submit and so he sees a dialog like "do you really want to submit the form? Yes/No" and if yes the form is sent using ajax to my insert.php page if no the dialog is simply closed.
I've read in the official documentation and it looks like this is simply a graphical tweak to show any #page of my jqm web app like a dialog.
How can I use this dialog page as confirm / cancel of my form submission?
To be clearer: I don't want to use standard javascript like:
function insertClienti()
{
$('#form').submit(function(e) {
if(!confirm('really submit the form?')) {
e.preventDefault();
return;
}
$.post("insert.php", $("#form").serialize());
});
}
but only jQuery Mobile's dialog.
Thanks for your time and patience.

I was simply using the wrong jQuery Mobile component.
Popup dialogs are simply made for this and are very easy to use.
The documentation is here:
http://jquerymobile.com/demos/1.2.0-alpha.1/docs/pages/popup/
Here's the code I used in my app (I use bassistance validator):
$(document).bind('pageinit', function () {
validaFormInserimento();
});
function insertClienti()
{
$.post("insert.php", $("#form_inserimento_clienti").serialize());
}
function validaFormInserimento()
{
$("#form_inserimento_clienti").validate({
rules: {
nick: "required"
},
messages: {
nick: "Campo obbligatorio"
},
errorPlacement: function(error, element){
if (element.attr("name") === "nick") {
error.insertAfter($(element).parent());
} else {
error.insertAfter(element);
}
},
submitHandler: function(form){
$( "#popupDialog" ).popup( "open" );
}
});
}
function disabilitaSubmit()
{
$('input,select').keypress(function(event) { return event.keyCode != 13; });
}
function insertClienti()
{
$.post("insert.php", $("#form_inserimento_clienti").serialize());
$( "#popupDialog" ).popup( "close" );
$("#form_inserimento_clienti").each(function() {
this.reset();
});
}

Inserting dynamic panel jquery mobile

In my app I would like to re-use the panel so I call this function when opening index.html:
var add_panel=function() {
//add button
$('[data-role="header"]').append('Menu');
//panel
$.get('panel.html').success(function(data) {
$('div[data-role="page"]').append(data);
$('#leftpanel').trigger('create');
$('#leftpanel').panel();
});
//open panel
$('body').on('click', '.ui-icon-bars', function() {
$("#leftpanel").panel("toggle");
});
}
This works great on the first page and when returning to this page from another page.
I had hoped to call the same function inside "pagecontainertransition" to add the panel to other pages as well, but this doesn't seem to work:
//handle page transitions
$('body').on('pagecontainertransition', function(event, ui) {
add_panel();
});
Can this be done?

jQuery Ajax Form Submit Fails

I am developing an MVC4 mobile app that uses several forms which are loaded into a section on the layout via ajax. I've got jQuery mobile set with Ajax turned off so I can manage the Ajax myself. Most of the forms work fine, the load and submit via ajax as they should. However, so far there is one form that refuses to fire the form submit and submit the form via ajax like the rest. First, the form is loaded when a user clicks to add a contact and this works fine:
// Handle the add contact button click
$('#btnAddNewContact').on('click', function (e) {
e.preventDefault();
// Make sure a location was selected first.
var locationID = $('#cboLocation').val();
if (locationID.length === 0) {
//$('#alertTitle').text('REQUIRED');
$('#alertMsg').html("<p>A Contact must be associated with a Location.</p><p>Please select or add a Location first.</p>");
$('#alertDialogDisplay').click();
} else {
SaveOpportunityFormState();
$.cookie('cmdLocationId', locationID, { path: '/' });
$.mobile.loading('show');
$.ajax({
url: '/Contact/Add',
type: 'GET',
cache: false,
success: function (response, status, XMLHttpRequest) {
$('section.ui-content-Override').html(response);
// Refresh the page to apply jQuery Mobile styles.
$('section.ui-content-Override').trigger('create');
// Force client side validation.
$.validator.unobtrusive.parse($('section.ui-content-Override'));
},
complete: function () {
$.cookie('cmdPreviousPage', '/Opportunity/Add', { path: '/' });
AddContactLoad();
ShowSearchHeader(false);
$.mobile.loading('hide');
},
error: function (xhr, status, error) {
// TODO - See if we need to handle errors here.
}
});
}
return false;
});
Notice that after successfully loading the form the AddContactLoad() function is fired. This works fine and here is that code:
function AddContactLoad() {
$('#contactVM_Phone').mask('(999) 999-9999? x99999');
$('#frmAddContact').on('submit', function (e) {
e.preventDefault();
if ($(this).valid()) {
$.mobile.loading('show');
$.ajax({
url: '/Contact/Add',
type: 'POST',
cache: false,
data: $(this).serialize(),
success: function (response, status, XMLHttpRequest) {
if (!response) { // Success
ReturnToAddOpportunity();
} else { // Invalid Form
$('section.ui-content-Override').html(response);
// Force jQuery Mobile to apply styles.
$('section.ui-content-Override').trigger('create');
// Force client side validation.
$.validator.unobtrusive.parse($('section.ui-content-Override'));
AddContactLoad();
$.mobile.loading('hide');
}
},
complete: function () {
},
error: function (xhr, status, error) {
// TODO - See if we need to handle errors here.
}
});
}
return false;
});
$('#btnCancel').on('click', function (e) {
e.preventDefault();
// See where add contact was called from.
var previousPage = $.cookie('cmdPreviousPage');
if (previousPage.indexOf("Detail") >= 0) {
ReturnToOpportunityDetails();
} else {
ReturnToAddOpportunity();
}
return false;
});
}
If I click the cancel button, that code is fired so I know this is working too. Here is my form code:
#using (Html.BeginForm("Add", "Contact", FormMethod.Post, new { #id = "frmAddContact" }))
{
#Html.ValidationSummary(true)
#Html.AntiForgeryToken()
-- Form Fields Here --
<div class="savecancel" >
<input type="submit" value="Save" data-mini="true", data-theme="b", data-inline="true" />
Cancel
</div>
}
As you can see the form is named frmAddContact and that is what the AddContactLoad() function is attaching the submit event to. To save my sole I cannot figure out why the form does not submit via the ajax post like every other form in the app. Am I missing some kind of initialization, I just don't know. If anyone can please help I'd really appreciate it!!
As it turns out, I had created a custom unobtrusive Ajax validator for a phone number then copied and pasted it to do the same with a zip code. Unfortunately in the process I forgot to rename a variable and thus an error was occurring in the validation script which caused the problem. In the mean time, if you're reading this, you might take a note of the code here and how to inject HTML into a page via Ajax and jQuery mobile. I've never found this in a book or on the web and it contains some very useful methodology and syntax. On the form submit the reason I'm checking for the empty response is I just return null from the controller to validate the form was valid and the save worked in which case I send them to a different HTML injection i.e. that page they originally came from. If null is not returned I inject that page with the HTML containing the original form and error markup so the user can make corrections then resubmit. I'm also calling a form load method that attaches handlers to the HTML once it's injected into the main page. Hope this helps somebody!

jQuery UI dialogs: how to close dialog when click outside?

In docs I didn't see such information.
There are options to close dialog in such cases:
1) push Esc;
2) click on "OK" or "Close" buttons in the dialog.
But how to close dialog if click outside?
Thanks!
Here are 2 other solutions for non-modal dialogs:
If dialog is non-modal Method 1:
method 1: http://jsfiddle.net/jasonday/xpkFf/
// Close Pop-in If the user clicks anywhere else on the page
jQuery('body')
.bind(
'click',
function(e){
if(
jQuery('#dialog').dialog('isOpen')
&& !jQuery(e.target).is('.ui-dialog, a')
&& !jQuery(e.target).closest('.ui-dialog').length
){
jQuery('#dialog').dialog('close');
}
}
);
Non-Modal dialog Method 2:
http://jsfiddle.net/jasonday/eccKr/
$(function() {
$( "#dialog" ).dialog({
autoOpen: false,
minHeight: 100,
width: 342,
draggable: true,
resizable: false,
modal: false,
closeText: 'Close',
open: function() {
closedialog = 1;
$(document).bind('click', overlayclickclose);
},
focus: function() {
closedialog = 0;
},
close: function() {
$(document).unbind('click');
}
});
$('#linkID').click(function() {
$('#dialog').dialog('open');
closedialog = 0;
});
var closedialog;
function overlayclickclose() {
if (closedialog) {
$('#dialog').dialog('close');
}
//set to one because click on dialog box sets to zero
closedialog = 1;
}
});
I found solution on ryanjeffords.com:
<script type="text/javascript">
$(document).ready(function() {
$("#dialog").dialog();
$('.ui-widget-overlay').live("click",function(){
$("#dialog").dialog("close");
});
});
</script>
If dialog is modal, then paste these 3 lines of code in the open function when you create your dialog options:
open: function(event,ui) {
$('.ui-widget-overlay').bind('click', function(event,ui) {
$('#myModal').dialog('close');
});
}
Facing the same problem, I have created a small plugin that enables to close a dialog when clicking outside of it whether it a modal or non-modal dialog. It supports one or multiple dialogs on the same page.
More information on my website here: http://www.coheractio.com/blog/closing-jquery-ui-dialog-widget-when-clicking-outside
The plugin is also on github: https://github.com/coheractio/jQuery-UI-Dialog-ClickOutside
Laurent
This is my solution.
I have, for example
<div id="dialog1">Some content in here</div>
<div id="dialog2">Different content in here</div>
<div id="dialog3">And so on...</div>
Each div gets opened as a dialog depending on what the user interacts with. So being able to close the currently active one, I do this.
// This closes the dialog when the user clicks outside of it.
$("body").on('click', '.ui-widget-overlay', function() {
if( $("div.ui-dialog").is(":visible") )
{
var openDialogId = $(".ui-dialog").find(".ui-dialog-content:visible").attr("id");
if ($("#"+openDialogId).dialog("isOpen"))
{
$("#"+openDialogId).dialog('close');
}
}
});

How to create a modal JQuery UI dialog from a Html page fragment fetched by $.get()

with the below code, I'm able to add a page fragment to an other page. The page contains a form to be posted to a certain action method.
$("#ul-menu a").click(function () {
$.get($(this).attr("href"), function (response) {
$("#dialog-div div").replaceWith($(response));
});
return false;
})
Instead of having the form anywhere in the page, I'd like to get it as a modal JQueryUI dialog.
How can I do that.
Thanks for helping.
This will work for you. Also, I've added a better method of preventing the original click. Instead of returning false, which kills all bubbling, you should use event.preventDefault();
$("#ul-menu a").click(function (event) {
event.preventDefault();
$.get($(this).attr("href"), function (response) {
$(response).dialog({ modal : true });
});
})
You don't even need to insert the response into the page.
You can just do this:
var myDialog = $(response).dialog();
EDIT
Not the above snippet won't create a modal dialog, I assumed you know you need to pass in { modal: true } as part of your configuration.

Ckeditor update textarea

I am trying to get the ckeditor working. Obviously it doesn't make use of the textarea so on submit the form doesn't submit the text in the editor. Beceause I make use of polymorphic associations etc. I can't make a onsubmit function to get the value of the textarea (when the form is submitted) .
So I found this question: Using jQuery to grab the content from CKEditor's iframe
with some very good answers. The answers posted there keep the textarea up to date. That is very nice and just what I need! Unfortunately I can't get it to work.
Does somebody know why (for example) this doesn't work?
I have a textarea (rails but it just translates to a normal textarea):
<%= f.text_area :body, :id => 'ckeditor', :rows => 3 %>
And the following js:
if(CKEDITOR.instances.ckeditor ) {
CKEDITOR.remove(CKEDITOR.instances.ckeditor);
}
CKEDITOR.replace( 'ckeditor',
{
skin : 'kama',
toolbar :[['Styles', 'Format', '-', 'Bold', 'Italic', '-', 'NumberedList', 'BulletedList', 'Link']]});
CKEDITOR.instances["ckeditor"].on("instanceReady", function()
{
//set keyup event
this.document.on("keyup", CK_jQ);
//and paste event
this.document.on("paste", CK_jQ);
}
function CK_jQ()
{
CKEDITOR.instances.ckeditor.updateElement();
}
I get the following "error" in my firebug.
missing ) after argument list
[Break on this error] function CK_jQ()\n
Before submit do:
for(var instanceName in CKEDITOR.instances)
CKEDITOR.instances[instanceName].updateElement();
have you figured it out?
I'm using CKEditor version 3.6.1 with jQuery form submit handler. On submit the textarea is empty, which to me is not correct. However there is an easy workaround which you can use, presuming all your CKEditor textareas have the css class ckeditor.
$('textarea.ckeditor').each(function () {
var $textarea = $(this);
$textarea.val(CKEDITOR.instances[$textarea.attr('name')].getData());
});
Execute the above before you do your submit handling ie. form validation.
Thanks #JohnDel for the info, and i use onchange to make it update every change.
CKEDITOR.on('instanceReady', function(){
$.each( CKEDITOR.instances, function(instance) {
CKEDITOR.instances[instance].on("change", function(e) {
for ( instance in CKEDITOR.instances )
CKEDITOR.instances[instance].updateElement();
});
});
});
Combination of all of the above answers into one.
Create a new custom.js file and add this:
CKEDITOR.on('instanceReady', function(){
$.each( CKEDITOR.instances, function(instance) {
CKEDITOR.instances[instance].on("instanceReady", function() {
this.document.on("keyup", CK_jQ);
this.document.on("paste", CK_jQ);
this.document.on("keypress", CK_jQ);
this.document.on("blur", CK_jQ);
this.document.on("change", CK_jQ);
});
});
});
function CK_jQ() {
for ( var instance in CKEDITOR.instances ) { CKEDITOR.instances[instance].updateElement(); }
}
You don't have to worry about the name of the textarea, just add a class ckeditor in the textarea, the above and you are done.
ADD Function JavaScript for Update
function CKupdate() {
for (instance in CKEDITOR.instances)
CKEDITOR.instances[instance].updateElement();
}
It's work. Cool
Just Add
CKEDITOR.instances.textAreaClientId.on('blur', function(){CKEDITOR.instances. textAreaClientId.updateElement();});
where textAreaClientId is your instance name
Regards
CKEDITOR.instances["ckeditor"].on("instanceReady", function()
{
//set keyup event
this.document.on("keyup", CK_jQ);
//and paste event
this.document.on("paste", CK_jQ);
})
I just increase that to the response of T.J. and worked for me:
$("form").on("submit", function(e){
$('textarea.ckeditor').each(function () {
var $textarea = $(this);
$textarea.val(CKEDITOR.instances[$textarea.attr('name')].getData());
});
});
On load:
$(function () {
setTimeout(function () {
function CK_jQ(instance) {
return function () {
CKEDITOR.instances[instance].updateElement();
};
}
$.each(CKEDITOR.instances, function (instance) {
CKEDITOR.instances[instance].on("keyup", CK_jQ(instance));
CKEDITOR.instances[instance].on("paste", CK_jQ(instance));
CKEDITOR.instances[instance].on("keypress", CK_jQ(instance));
CKEDITOR.instances[instance].on("blur", CK_jQ(instance));
CKEDITOR.instances[instance].on("change", CK_jQ(instance));
});
}, 0 /* 0 => To run after all */);
});
There have been some API changes with the latest versions of CKEditor, so here's an answer for CKEditor 5:
let ckeditor;
// Create a CKEditor, and store its handle someplace that you may
// access later. In this example, we'll use the `ckeditor` variable:
ClassicEditor
.create(document.querySelector("textarea"), {})
.then(editor => { ckeditor = editor; });
// When your form submits, use the `updateSourceElement` method
// on the editor's handle:
document.querySelector("form").addEventListener("submit", function() {
ckeditor.updateSourceElement();
});
To my knowledge, CKEditor does this automatically when you submit a form, so this particular example shouldn't actually do anything. But it is useful when you need the content of the textarea to udpate without submitting the form that contains it.
All above answer are focusing on how to fix this error but I want to take the answer on what cause me this error
I had a
<textarea class="ckeditor" rows="6" name="Cms[description]"></textarea>
changed to
<textarea class="ckedit" rows="6" name="Cms[description]"></textarea>
I changed class attribute value to anything other than ckeditor and boom error gone.
Hope that help
