jQuery UI Dropdown value doesnt change - jquery-ui

I have a dropdown menu which contains 3 options. This menu is shown inside a modal jQuery UI dialog.
I can open open the dialog and choose one of the three options. The chosen option is stored in a variable. This works fine. But if I open the dialog again and choose another option, the variable does not change - it contains the value of first selection.
$("#button").click(function()
{
var diag = "<select id='diagDropdown'>"
+"<option>Option 1</option>"
+"<option>Option 2</option>"
+"<option>Option 3</option>"
+"</select>";
$(diag).dialog(
{title: "Choose Option"},
{autoOpen: "false"},
{modal: "true"},
{draggable: "false"},
{ buttons: {OK: dialogOK} });
function dialogOK()
{
var chosenOption=$("#diagDropdown option:selected").val().toLowerCase();
//working with chosen option
$(this).dialog("close");
});
Hope you can help me. Thanks in advance!

The problem is that each time you click on your element with id "button", you are creating a new dropdown with id "diagDropdown" in a new dialog.
Then your code :
var chosenOption=$("#diagDropdown option:selected").val().toLowerCase();
is always selecting the first dropdown with id "diagDropdown" in the DOM.
Try this :
<input type="button" value="click me" id="button"/>
<script type="text/javascript">
// On DOM ready
$(function() {
var dropdown =
$('<select id="diagDropdown"> ' +
'<option>Option 1</option>' +
'<option>Option 2</option>' +
'<option>Option 3</option>' +
'</select>');
// Create the dialog (only once)
dropdown.dialog({
title: "Choose Option",
autoOpen: false,
modal: true,
draggable: false,
buttons: {
"OK": function() {
var chosenOption=$('#diagDropdown option:selected').val().toLowerCase();
//working with chosen option
$(this).dialog('close');
}
}
});
// Bind click event : on click just open the existing dialog
$('#button').click(function() {
$('#diagDropdown').dialog('open');
});
});
</script>

Update jquery ui dialog from another jquery ui dialog

I have a jquery dialog and from this one, i open another dialog, where user insert some data. How can I update this user data from the second dialog to the first one, without closing them?
Is this possible? Are some examples in the web?
Thanks in advance
ok so this is my script, which opens the second dialog. I open this dialog with a link, which calls a function in my mvc controller, and this returns the partial view with the datas...
<script type="text/javascript">
$(document).ready(function () {
$("#dialog2").dialog({
bgiframe: false,
autoOpen: false,
height: 200,
resizable: false,
modal: true,
buttons: {
OK: function () {
$("#dialog2 > form").submit();
$(this).dialog('close');
},
Abbrechen: function () {
$(this).dialog('close');
}
}
});
$('#changePW').click(function () {
$('#dialog1').dialog('open')
});
});
</script>
#Roysvork: then I have to but this in the buttons OK function?
As a dialog is simply an html element underneath, you can still access said element using jQuery in the usual fashion:
var dialog1 = $("#dialog1");
var dialog2 = $("#dialog2");
dialog1.dialog("show");
dialog2.dialog("show");
So in your event handler for dialog 1 you can just do :
var value = dialog2.find("#inputbox").val();
dialog2.find("#textbox").val(value) ;
etc...

jQuery UI Dialog Will Not Close

Given the following script:
$(function () {
$(".editLink").button();
$('#editPersonDialog').dialog({
autoOpen: false,
width: 800,
resizable: false,
title: 'Edit Person',
modal: true,
buttons: {
"Save": function () {
$("#update-message").html('');
$("#updatePersonForm").submit();
},
"Close": function () {
$(this).dialog('close');
}
},
close: function (event, ui) {
$(this).dialog('close');
}
});
$(".editLink").click(function () {
var dialogDiv = $('#editPersonDialog');
var linkObj = $(this);
var viewUrl = linkObj.attr('href');
$.get(viewUrl, function (data) {
dialogDiv.html(data);
//validation
var $form = $("#updatePersonForm");
// unbind existing validation
$form.unbind();
$form.data("validator", null);
// check document for changes
$.validator.unobtrusive.parse(document);
// re-add validation with changes
$form.validate($form.data("unobtrusiveValidation").options);
// open dialog
dialogDiv.dialog('open');
});
return false;
});
});
function updateSuccess() {
if ($("#update-message").html() == "True") {
$('#editPersonDialog').dialog('close');
$("#commonMessage").html("Update Complete");
$("#commonMessage").delay(400).slideDown(400).delay(3000).slideUp(400);
}
else {
$("#update-message").show();
}
}
If I click the "X" button on the dialog the form closes fine. If I click the "Close" button then it does not close. I have verified that the code for the "Close" button is being called.
Both the "X" button and the "Close" button are both running the same statement: '$(this).dialog('close');'. Why would one work and the other not work?
As an aside the dialog will not open a second time unless I refresh the page. I imagine that these 2 problems may be related.
I have found many people with similar problems and a number of different solutions that worked for them. Unfortunately none of them worked for me.
Further Info:
The dialog displays a partial view in an Ajax form:
#using (Ajax.BeginForm("Edit", "Person", null,
new AjaxOptions
{
UpdateTargetId = "update-message",
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
OnSuccess = "updateSuccess"
},
new { #id = "updatePersonForm" }))
{
#Html.ValidationSummary(true)
<div id="update-message" class="hiddenDiv"></div>
<div class="blockGraygradient">
#Html.Partial("_CreateEditCommon")
#Html.HiddenFor(model => model.SelectedPerson.Id)
#Html.HiddenFor(model => model.SelectedPerson.RowVersion)
#Html.HiddenFor(model => model.SelectedPerson.CreateTime)
</div><p/>
}
Try using this instead.
$(this).dialog('destroy');
We had exactly the same problem. In the end, every time you re-opened the dialog it was actually re-injecting the dialog markup into the DOM. Then, when you click close (for the second time) it only closes the first occurrence of the dialog, but not necessarily the one that's open. You can check this using a run-time DOM inspector like FireBug or Chrome's built-in developer tools.
I found out that the cause of both problems (the close button not working and being unable to show the dialog more than once without refreshing the page) was that I had included references to my script files in both my main page and the partial view being displayed by the dialog. Once I removed the script references from the partial view the problems disappeared.
(As an aside this has now raised another problem to do with an Ajax update back onto the main page when the dialog is closed. I think this is the reason that I put the scripts into the partial view in the first place).
You have too much recursion. You don't need to subscribe to the close event of your jQuery dialog and invoke $(this).dialog('close'); inside it. Simply comment this line or remove completely the close event subscription:
$('#editPersonDialog').dialog({
autoOpen: false,
width: 800,
resizable: false,
title: 'Edit Person',
modal: true,
buttons: {
"Save": function () {
$("#update-message").html('');
$("#updatePersonForm").submit();
},
"Close": function () {
$(this).dialog('close');
}
}
});

pass variable to jquery dialog

I am wanting to pass a variable to a jquery dialog window. I am using classic ASP and have onyl really touched on the world of jquery. I have spent a few hours researching and tring to use the .data method but are having trouble. Your time and assitance would be very much apriciated!
Here is my stripped down page:
$(function(){
// Dialog
$('#dialog').dialog({
autoOpen: false,
show: "slide",
hide: "fade",
width: 452,
modal: true,
buttons: {
"Ok": function() {
PostItNote.submit();
$(this).dialog("close");
},
"Cancel": function() {
$(this).dialog("close");
}
}
});
// Dialog Link
$('#dialog_link').click(function(){
$('#dialog').dialog('open');
return false;
});
});
and this is how I call the window:
<a href='#' id='dialog_link' CLASS='OrangeButton'> Show Window </a>
and the contents of my window:
<div ID="dialog" TITLE="Periodic Report">
stuff here
</div>
Why can I not do this:
<a href='#' id='dialog_link(someValue)' CLASS='OrangeButton'> Show Window </a>
Thank you in advance
How it is used in the ASP loop is:
do until Products.EOF
--other code here---
<a href='#' id='dialog_link(Products(0))' CLASS='OrangeButton'>
--other code here---
products.moveNext
loop
The dialog is just a div on your page, so it can't really be "passed" a value. It can be manipulated by any JavaScript variables in scope though. You could change your click handler to use a variable to manipulate the dialog:
var myVariable = "Some new text for the dialog";
$('#dialog_link').click(function(){
//New code to "pass" a value to the dialog
$('#dialog').text(myVariable);
$('#dialog').dialog('open');
return false;
});
Or you could use the open member of the dialog:
...
width: 452,
open: function() { $('#dialog').text(myVariable); },
modal: true,
...
To make changes to the dialog div whenever it is opened.
The code id='dialog_link(someValue)' will not do anything, as the id attribute cannot make function calls, only event handlers like onchange can do that. Even if it could, dialog_link is not a function that can be passed a value. It is just the id of another element.
I'm sure you're probably already aware, but the jQuery documentation is very useful- here are the docs for dialog.
Edit
In response to your comment: I would drop the $('#dialog_link').click(); statement and change the link code to the following:
<a href='#' class='OrangeButton' onclick='openDialog(someValue);'>Show Window</a>
And then add the JavaScript function to be called on the click event:
function openDialog(value) {
$('#dialog').text(value);
$('#dialog').dialog('open');
}
Edit 2
Inside of the ASP loop something like this should do the trick:
Response.Write("<a href='#' onclick='openDialog(" & Products(0) & ");'>Show</a>")
This will create an <a></a> element on the page with an onclick handler that passes the desired value to openDialog, making it accessible by the dialog.
I changed the code for the link slightly so that it all fit on one line, but you could always add back the class='OrangeButton' and all that if you'd like.

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

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 dialog using jquery-ui without html div specified

Using jquery-ui to create a dialog is pretty easy:
<script>
$(function() {
$( "#dialog" ).dialog();
});
</script>
<div id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>
...but one still needs a div in the HTML for this to work. In Dojo:
var dlg = new dijit.Dialog({
title:"dialog",
style: "width:30%;height:300px;"
});
dlg.show();
would just do the trick without anything specified in the html section, can jquery-ui do this? (I have to use jquery-ui here)
Thanks,
David
While I'm not sure why you would want to open a dialog with no content, you could easily create a new one on the fly and invoke the jquery dialog against it:
$("<div>hello!</div>").dialog();
basic code
var d = $("#someId");
if (d.length < 1)
d = $("<div/>").attr("id", "someId")
.appendTo("body");
else
d.dialog('destroy');
d.html('some message')
.dialog({ some_options })
.dialog("open");
and you can probably put rap this in an extension method.
Update (my full code listing)
(function($) {
$.extend({
showPageDialog: function (title, content, buttons, options) {
/// <summary>Utility to show a dialog on the page. buttons and options are optional.</summary>
/// <param name="buttons" type="Object">Dialog buttons. Optional, defaults to single OK button.</param>
/// <param name="options" type="Object">Additional jQuery dialog options. Optional.</param>
if (!buttons)
buttons = { "Ok": function () { $(this).dialog("close"); } };
var defOptions = {
autoOpen: false,
modal: true,
//show: "blind",
//hide: "explode",
title: title,
buttons: buttons
};
if (options)
defOptions = $.extend(defOptions, options);
var pd = $("#pageDialog");
if (pd.length < 1)
pd = $("<div/>").attr("id", "pageDialog")
.appendTo("body");
else
pd.dialog('destroy');
pd.html(content)
.dialog(defOptions)
.dialog("open");
}
}//end of function show...
)//end of extend Argument
})(jQuery)
Sample Usage
$.showPageDialog(title, message, {
"Yes": function () {
$(this).dialog("close");
// do something for 'yes'
},
"No": function () {
// do something for no
}
}
var div = document.createElement('div');
div.innerHTML = "Hello World";
$(div).dialog();
Juan Ayalas solution should work for modal Dialogs.
For a non modal dialog it would be better to track the id inside the function.
I use the following code which is not perfect but should work to ensure that the
id is unique. The code is nearly equal to Juan Ayalas example but uses a counter to avoid a duplicate id. (Furthermore I deleted the OK-Button as default).
(function($)
{
var dCounter=0; //local but "static" var
$.extend({
showPageDialog: function (title, content, buttons, options) {
/// <summary>Utility to show a dialog on the page. buttons and options are optional.</summary>
/// <param name="buttons" type="Object">Dialog buttons. Optional, defaults to nothing (single OK button).</param>
/// <param name="options" type="Object">Additional jQuery dialog options. Optional.</param>
if (!buttons)
buttons = {}; //{ "Ok": function () { $(this).dialog("close"); } };
var defOptions = {
autoOpen: false,
width: "auto",
modal: false,
//show: "blind",
//hide: "explode",
title: title,
buttons: buttons
};
if (options)
defOptions = $.extend(defOptions, options);
dCounter++;
//console.log("dCounter is " + dCounter);
var pdId = "#pageDialog"+dCounter;
var pd = $(pdId);
if (pd.length < 1)
pd = $("<div/>").attr("id", pdId)
.appendTo("body");
else
pd.dialog('destroy');
pd.html(content)
.dialog(defOptions)
.dialog("open");
}//end of function showPageDialog
}//end of extend options
)//end of extend argument
}//end of function definition
