jqueryui - if statement within button click callback - jquery-ui

Have I done something obviously obtuse, or is there a special format for evaluating if() conditions within a jqueryUI button callback?
$(function(){
var focus_control = '';
$( '#alert' ).dialog({
autoOpen:false,
show: 'fade',
hide: 'fade',
buttons: {
Ok: function() {
$(this).dialog('close');
//Next line works if uncommented
//$('#username').focus();
//This if block breaks the js, but all works if this block commented out
//var focus_control assigned elsewhere (ajax)
if (focus_control=='staff_pick') {
$('#staff_pick').focus();
}else if {focus_control=='username') {
$('#username').focus();
}
}
}
});
});
Is there a better way to rewrite this? I tried:
if (focus_control!='') {
$('#%focus_control%').focus();
}

Error: cannot call methods on dialog prior to initialization; attempted to call method 'open'

Just a little preface... I am fairly new to jQuery so if something looks wrong or redundant please feel free to offer any helpful suggestions.
Now for the issue. I have 2 modals that are initiated from 2 separate links on the page.
The first modal was fairly problem free. It is a simple form that posts back to the same page. If you are wondering what the items in the "close:" section are, they are form fields that I want to clear the values on when the dialog is closed.
Once I added the second one I have had problems. This modal calls a coldfusion page into a modal to display pictures. The problems occur after opening up the second one. I can not close the second modal from the "close" button. I get the following error.
Error: cannot call methods on dialog prior to initialization; attempted to call method 'close'
I have to close it from the "x" in the upper right hand corner of the modal. After I close it, I get an error when trying to open up the first on.
Error: cannot call methods on dialog prior to initialization; attempted to call method 'open'
Here is the code for it.
$(document).ready(function() {
$(".dig").click(function() {
//based on which we click, get the current values
var cItemName = $("#checklistItemName").attr( "title");
var c2id = $("#check2id").attr( "title");
$("#ItemName").html(cItemName);
$("#ItemID").html(c2id);
$("#objCheckItemName").val(cItemName);
$("#objCheck2ID").val(c2id);
console.log(cItemName);
console.log(c2id);
});
$( "#image-form" ).dialog({
autoOpen: false,
height: 450,
width: 650,
modal: true,
buttons: {
"Submit": function() {
$('#mForm').submit();
return true;
},
Cancel: function() {
$( this ).dialog( "close" );
}
},
close: function() {
$('#defaultSectionName')
.val('');
$('#defaultSectionDesc_hidden')
.val('');
$('#Photo')
.val('');
$('#objCheck2ID')
.val('');
$('#Check21')
.val('');
},
zIndex: 500
});
The next piece of code is where I believe the problems are occurring.
$( "#image_trigger" )
.click(function() {
$( "#image-form" ).dialog( "open" );
});
var dlg=$('#register').dialog({
title: 'Case Pictures',
resizable: true,
autoOpen:false,
modal: true,
hide: 'fade',
width:650,
height:450,
buttons: {
close: function() {
$( this ).dialog( "close" );
}
},
zIndex: 500
});
$('#reg_link').click(function(e) {
e.preventDefault();
var linkurl=('assets/includes/modalPictures.cfm' + '?'
+ 'id=' + $("#objCheck2ID").val()
);
dlg.load(linkurl, function(){
dlg.dialog('open');
});
});
jQuery UI: 1.10.1
jQuery: 1.9.1
Server Side: Coldfusion
The HTML is pretty extensive. If you need to see any part of it please let me know. Thanks for your help!
Upper case?
Close: function() {
You have to initialize your jquery dialog before calling the open function.
<script type="text/javascript">
$(document).ready(function () {
initializeDialog();
});
</script>
And change your js file to have the dialog code in initializeDialog() function.
function initializeDialog(){
$("#your-dialog-id").dialog({
autoOpen: false,
buttons: {
"Cancel": function() {
$(this).dialog("close");
}
},
modal: true,
resizable: false,
width: 600px,
height: 400px
});
}

Pass a variable to JQuery UI dialog

I am deleting a record using PHP. I want to use a JQuery UI dialog to confirm the action, but I dont know how to pass a variable (my RecordID) to the redirect URL function, or allow the URL to access window.location.href.
$("#confirm" ).dialog({
resizable: false,
autoOpen: false,
modal: true,
buttons: {
'OK': function() {
window.location.href = 'url and myvar??';
$( this ).dialog( "close" );
},
'Cancel': function() {
$( this ).dialog( "close" );
}
}
});
$("#delete").click(function() {
$("#confirm").dialog( "open" ).html ( "Are U Sure?" );
return false;
});
HTML
<a href='index.php?recordid=$row[recordid]' id='delete'>DELETE</a>
Is there a good way to do this?
You can try using the .data() method to store data for you. Take a look at this answer
Passing data to a jQuery UI Dialog
For example to pass a variable, you can store it using the data function, before opening the dialog
$("#dialog_div")
.data('param_1', 'whateverdata')
.dialog("open");
Then you can get this back by:
var my_data = $("#dialog_div").data('param_1')
You want to change the configuration of the dialog on click (in this case, the behaviour of the Ok button). For that your have many solutions all of them ugly (imo). I would advice generating a dialog on the fly, and destroying it once it has been used, something like this:
$("#delete").click(function(ev) {
ev.preventDefault(); // preventDefault should suffice, no return false
var href = $(this).attr("href");
var dialog = $("<div>Are you sure?</div>");
$(dialog).dialog({
resizable: false,
autoOpen: true,
modal: true,
buttons: {
'OK': function() {
window.location = href;
$( this ).dialog( "close" );
},
'Cancel': function() {
$( this ).dialog( "close" );
}
},
close: {
$( this ).remove();
}
});
});
Or even better, encapsulate the confirm dialog into a function so that you can reuse it, like so:
function confirmDialog(msg) {
var dialog = $("<div>"+msg+"</div>");
var def = $.Deferred();
$(dialog).dialog({
resizable: false,
autoOpen: true,
modal: true,
buttons: {
'OK': function() {
def.resolve();
$( this ).dialog( "close" );
},
'Cancel': function() {
def.reject();
$( this ).dialog( "close" );
}
},
close: {
$( this ).remove();
}
});
return def.promise();
}
And then use it like so
confirmDialog("are your sure?").done(function() {
window.location = $(this).attr("href");
}).fail(function() {
// cry a little
});
You may have to check if the deferred object has been rejected or resolved before you close the dialog, to ensure the confirm rejects on close (and not just on pressing the 'Cancel' button). This can be done with a def.state() === "pending" conditional.
For more information on jquery deferred: http://api.jquery.com/category/deferred-object/
Deleting actions probably shouldn't be done using a GET, but if you wanted to do it that way I would recommend using the $.data in jQuery so each link had a data-record-id attribute. Then on click of one of the links, it pops up the dialog and when confirmed it adds that to the URL, and redirects.
Example:
$(function(){
$(".deleteLink").click(function(){
var id = $(this).data("record-id");
var myHref = $(this).attr('href');
$("#confirmDialog").dialog({
buttons:{
"Yes": function()
{
window.location.href = myHref + id;
}
}
});
});
});
<a class="deleteLink" data-record-id="1">Delete</a>
...
<div id="confirmDialog">
<p>Are you sure?</p>
</div>
HTML
<a data-title="Title" data-content="content" data-mydata="1" class="confirmation-dialog" href="#">Link</a>
JS
$('.confirmation-dialog').confirm({
buttons: {
Yes: function(){
console.log(this.$target.attr('data-mydata'));
No: function(){
}
}
});

jQueryUI Datepicker in Dialog auto focus in IE9

I'm able to load and reopen jQueryUI Dialogs with a Datepicker as the first element in all browsers I've tried ... except IE 9.
If a Datepicker is the first element to receive focus when the Dialog opens, the Datepicker will auto launch. I'm able to suppress this behavior in FireFox and Chrome. IE 9 still launches the Datepicker on creation.
My open and close function for the Dialog are:
open: function (event, ui) {
$('#Date').blur(); // kill the focus
if ($('#Date').hasClass('hasDatepicker')) {
$("#Date").datepicker('enable');
}
else {
$("#Date").datepicker();
}
},
close: function (event, ui) {
$("#Date").datepicker('disable');
}
Here is the 'click' code
var dialogs = {};
$('#clicker').click(function (e) {
if (!dialogs['dlg']) {
loadAndShowDialog('dlg');
} else {
dialogs['dlg'].dialog('open');
}
});
var loadAndShowDialog = function (id) {
dialogs[id] = $('#dlg').clone().find('#ChangeMe').attr('id', 'Date').end()
.appendTo(document.body)
.dialog({ // Create the jQuery UI dialog
title: 'Testing',
modal: true,
resizable: true,
draggable: true,
width: 300,
open: see above
close: see above
};
jsfiddle showing this IE9 problem http://jsfiddle.net/stocksp/DdRLp/8/
What can I do to get IE to behave, short of not placing the Datepicker as the first element?
I don't have IE9 available at home so give this a try: http://jsfiddle.net/DdRLp/10/
I added a class to the datepicker input to make it easier to grab.
$(function() {
$(document).on("dialogcreate", "#dlg", function() {
$(".date_picker").datepicker();
$(".date_picker").datepicker("disable");
});
var dialogs = {};
$('#clicker').click(function(e) {
if (!dialogs['dlg']) {
loadAndShowDialog('dlg');
} else {
dialogs['dlg'].dialog('open');
}
});
var loadAndShowDialog = function(id) {
dialogs[id] = $('#dlg').clone().find('#ChangeMe').attr('id', 'Date').end().appendTo(document.body).dialog({ // Create the jQuery UI dialog
title: 'Testing',
modal: true,
resizable: true,
draggable: true,
width: 300,
open: function(event, ui) {
$("div#dlg form input").blur(); //takes focus off inputs
$(".date_picker").datepicker("enable");
},
close: function(event, ui) {
$(".date_picker").datepicker("disable");
}
});
};
});

jquery drag and drop function

This function takes an li element and adds it to another ul element. After this code is fired the jquery events attached to the children spans of the li element do not fire the first time they are clicked.
function AddToDropBox(obj) {
$(obj).children(".handle").animate({ width: "20px" }).children("strong").fadeOut();
$(obj).children("span:not(.track,.play,.handle,:has(.btn-edit))").fadeOut('fast');
$(obj).children(".play").css("margin-right", "8px");
$(obj).css({ "opacity": "0.0", "width": "284px" }).animate({ opacity: "1.0" });
if ($(".sidebar-drop-box ul").children(".admin-song").length > 0) {
$(".dropTitle").fadeOut("fast");
$(".sidebar-drop-box ul.admin-song-list").css("min-height", "0");
}
if (typeof SetLinks == 'function') {
SetLinks();
}
if(document.getElementById("ctl00_cphBody_hfRemoveMedia").value===""||document.getElementById("ctl00_cphBody_hfRemoveMedia").value===null)
{
document.getElementById("ctl00_cphBody_hfRemoveMedia").value=(obj).attr("mediaid");
}
else
{
var localMediaIDs=document.getElementById("ctl00_cphBody_hfRemoveMedia").value;
localMediaIDs= localMediaIDs.replace((obj).attr("mediaid"),"");
document.getElementById("ctl00_cphBody_hfRemoveMedia").value=localMediaIDs+", "+(obj).attr("mediaid");
}
}
Is there something missing in this code that would cause that?
UPDATE
thats exactly what I am using for the jquery sortable feature that actually calls the addtoDropbox Method().
// Make our dropbox a selectable & sortable.
$(".sidebar-drop-box ul").sortable({
connectWith: '.admin-left',
tolerance: "intersect",
handle: ".handle",
opacity: "0.5",
receive: function(event, ui) {
**AddToDropBox(ui.item)**;
},
start: function(event, ui) {
$(".sidebar-drop-box ul.admin-song-list").css("min-height", "70px");
isDraggingSong = true;
//soundManager.stopAll();
//$(".btn-stop").removeClass("btn-stop");
},
stop: function(event, ui) {
if ($(".sidebar-drop-box ul").children("li").length == 0) {
$(".dropTitle").fadeIn();
}
}
}); //.selectable({ filter: 'li', cancel: '.btn-stop,.btn-play,.notes,.btn-del,span.remove' });
// Do the same for our playlist.
$(".admin-left").sortable({
opacity: '0.5',
tolerance: "intersect",
handle: ".handle",
appendTo: 'appentToHolder',
items: "li.admin-song",
update: function(event, ui) {
$(ui.item).css("opacity", "0.0").animate({ opacity: "1.0" }, "medium");
if ($.browser.msie && $.browser.version == "7.0") {
$(ui.item).css("margin-bottom", "-6px");
}
},
receive: function(event, ui) {
AddToLeftList(ui.item);
},
start: function(event, ui) {
$(".admin-left li.ui-selected").removeClass("ui-selected");
isDraggingSong = true;
//soundManager.stopAll();
//$(".btn-stop").removeClass("btn-stop");
},
stop: function(event, ui) {
CheckLeftList();
},
connectWith: '.sidebar-drop-box ul'
}).selectable({ filter: 'li.admin-song', cancel: '.head *,.btn-stop,.btn-play,.notes,.btn-del,span.remove' }); // added .head * to fix bug# 1013
the bold line calls the function I added previously, which places the li element.
I am not sure exactly where the disconnect happens, but i know between these 2 code segments that it breaks something and the next click doesn't not work on the source ul. i ahve been struggling with this for days. I cant turn this back to my boss this shape...lol
thanx
It doesn't look like this function is adding something to a list.
This function first does a couple of
CSS changes to obj and it's
descendants.
Then it goes and calls the global
function SetLinks (if it is
defined).
And thirdly it sets the value of
the element
"ctl00_cphBody_hfRemoveMedia", which
is probably some kind of input.
Looks like this was pasted together from at least two other functions and would need refactoring.
I'm guessing that the cause for your lost events might be somewhere near a call to AddToDropBox.

Jquery UI Accordion - Cancel Change

I have been wrestling with this one for a while now.
I want to have a confirm() before someone changes the accordion.
I have tried:
$(document).ready(function() {
var edited = false;
$(".accordion-me").accordion({
autoHeight: false,
navigation: true,
changestart: function(event, ui) {
if (edited) {
if (!confirm("You have unsaved changes. Do you want to navigate away?") {
event.preventDefault();
event.stopPropagation();
event.stopImmediatePropagation();
return false;
}
}
}
});
});
With little joy! I have also tried something like this
$(".accordion-me h3").each(function() {
$(this).unbind("click");
$(this).click(function(e) {
if (confirm("You have unsaved changes! Do you want to navigate away?")) {
$(this).unbind("click");
$(".accordion-me").accordion({
autoHeight: false,
navigation: true,
changestart: function(event, ui) {
if (edited) {
if (!confirm("You have unsaved changes. Do you want to navigate away?") {
event.preventDefault();
event.stopPropagation();
event.stopImmediatePropagation();
return false;
}
}
}
});
$(this).click();
}
});
});
But again with no joy.
Any help would be greatly appreciated.
Cheers
Use an empty event when creating the accordion, which will allow you to manage the click event of the accordion using a jQuery .click function.
You can then process the confirm box and allow the accordion click event to be executed only if confirmed.
$(document).ready(function()
{
var edited = false,
accordion_me = $('.accordion-me');
// activate the accordion, but with an empty event
accordion_me.accordion({
autoHeight: false,
navigation: true,
event: ''
});
// here's the new accordion event
$('.accordion-me h3').click(function()
{
// find the index of the event being called
var i = $('.accordion-me h3').index(this);
// if we have unsaved changes and do not confirm, stop accordion execution
if (edited && !confirm('You have unsaved changes. Do you want to navigate away?'))
{
return false;
}
// continue with the accordion execution. Activate the requested event index.
accordion_me.accordion('activate', i);
return false;
});
});
If your accordion is collapsible (as mine is) your accordion will still work as it did before.
Also, if you only have 1 accordion, I would recommend using an id to call it instead of the .accordion-me class, which will save some overhead.
If you still need to use a class to call it, put an html tag before it, i.e. div.accordion-me.
You have to bind it to the click event on the anchor tag. For example, if your header links are:
header 1
code would be (also in the document.ready function)
$('.accordionHeaderLink').click(function(){
if (!confirm("You have unsaved changes. Do you want to navigate away?")) {
return false;
}
});
