JavaScript dialog pop up event wait for OK to be pressed

I got a delete (input submit) button which pops up a dialog (Alloy UI dialog, html) when clicked:
A.all("#RFB input.ConfirmDelete").each(function(node){
node.on('click', function(event) {
if(confirmed) {
showUserWaitDialog();
return true;
}
else {
deactivateKeyboardNav();
deleteConfirm(node, confirmDeleteMessage, function () { //Runs the function rendering the pop up
confirmed = true;
event.target.click();
showUserWaitDialog();
});
}
});
});
The problem is that the event is running async and thus performs the deletion, and not waiting for the user to click OK (calling the callback).
The deleteConfirm takes the following arguments
function deleteConfirm(link, pText, callback) {
The content in the pop up consists of:
var bodyContent = '<div class="vl-info vl-message"><h2>'+titleText+'</h2>'+
'<p>'+pText+'</p>' +
'<p class="more button-area">'+confirmButtonText+''+discardButtonText+'</p></div>';
And the button functions:
A.one('.deleteOK').on('click', function(e){
(jQuery.isFunction(callback)) && callback.apply();
confirmDialog.close();
confirmDialogOpen = false;
});
A.one('.deleteNotOK').on('click', function(e){
confirmDialog.close();
confirmDialogOpen = false;
return false;
});
How should I approach this?

Alloy UI provides a nice Dialog box API. It may be worth to see this example and apply for your requirement.
var dialog = new A.Dialog({
title : '<your dialog box title here>',
centered: true,
modal: false,
width: 600,
height: 250,
bodyContent: <You can keep the message to display here>,
buttons: [
{
label: 'Delete',
id: 'deleteBtn',
handler: function() {
//Place code to delete here. It get executed when user click on Delete button.
}
},
{
label: 'Cancel',
id: 'cancelActionItemBtn',
handler: function() {
this.close();
}
}
]
}).render();

Creating a suitable replacement for prompt

My users may use IE7 and I want to avoid using the prompt function. I have working code using prompt but am unsure of a good way to replace it.
My usage requirement is this. User clicks an image button and then has to OK/Cancel a prompt. If OK is pressed, a Reference is requested which is assigned to RemovePalletReference for use in code behind.
<asp:imagebutton id="ibRemoveFromPallet" runat="server" ImageUrl="../Images/Icons/removefrompallet.gif" OnClientClick="return ConfirmReroute();"></asp:imagebutton>
<asp:HiddenField ID="RemovePalletReference" runat="server" value="" ></asp:HiddenField>
You can see above that I first call ConfirmReroute() which is the following js function.
function ConfirmReroute()
{
if (confirm("Confirm Remove Unit From Pallet") == true)
{
var pmt;
do {
pmt = prompt("Please Enter a Reference:", "");
}
while ( pmt == null || pmt.length < 1);
document.getElementById('<%= RemovePalletReference.ClientID %>').value = pmt;
return true;
}
else
return false;
}
I wish to replace the code where the user has pressed OK to the confirm. I tried with jquery UI modal dialog but could not work it out. I think it may be workable using callbacks but this is a new subject to me and I'm struggling.
Please in answers show some code to help me out. Grateful for any assistance.

Ex
function confirmDialog(title, message, confirm, reject) {
var dialog = $('<div />').html(message).dialog({
appendTo: 'body',
title: title,
modal: true,
buttons: {
"OK": function () {
$(this).dialog("close");
confirm();
},
"cancel": function () {
$(this).dialog("close");
if ($.isFunction(reject)) {
reject();
}
}
},
close: function (event, ui) {
$(this).dialog('destroy');
$(this).remove()
}
})
}
function test(notes) {
confirmDialog('Confirm', 'Confirm Something', function () {
console.log('ok');
//what ever you want to do on confirmation has to go here
}, function () {
console.log('cancelled')
});
//any code added here will get executed before the confirm box is displayed
}
Demo: Fiddle

jQuery UI confirm dialog doesn't return true/false

$(function ()
{
$("#dialog-confirm").dialog(
{
autoOpen: false,
resizable: false,
height: 240,
modal: true,
buttons: {
"Delete": function ()
{
$(this).dialog("close");
return true;
},
Cancel: function ()
{
$(this).dialog("close");
return false;
}
},
close: function() {
;
}
});
});
function ShowDeleteConfirmation()
{
var activeEmelent = document.activeElement;
if (activeEmelent.innerHTML == 'Delete')
{
$('#dialog-confirm').dialog('open');
return false;
}
}
//aspx code
<asp:LinkButton ID="lbDelete" runat="server" Text="Delete" CssClass="wecc-grid-link" data-cmd="delete" OnClick="Delete_Click" OnClientClick=" return ShowDeleteConfirmation();" ></asp:LinkButton>
//Server side event
protected void Delete_Click(object sender, EventArgs e)
{
_deleteClicked = true;
LinkButton lb = sender as LinkButton;
GridViewRow row = lb.Parent.NamingContainer as GridViewRow;
if (row.RowState != (DataControlRowState.Selected | DataControlRowState.Edit) &&
row.RowState != (DataControlRowState.Alternate | DataControlRowState.Selected | DataControlRowState.Edit))
{
Delete(row);
}
else
{
SetRowState(row.RowIndex, DataControlRowState.Normal);
}
gvSaveState.DataSource = this.Data;
gvSaveState.AllowSorting = true;
gvSaveState.DataBind();
lbAddItem.Visible = true;
lbRefreshData.Visible = true;
}
The dialog pops up when I click on the delete link button in my gridview. But, upon Clicking Delete button in the dialog, it doesn't fire my Server Side click event. I do return a value 'true' when the Delete is clicked.
Appreciate your help here.

The jQuery dialog is essentially asynchronous. The standard confirm() function blocks execution until a result is returned. The jQuery dialog does not stop execution, so showDeleteConfirmation() always returns false, and your jQuery buttons are returning their values to nothing. If you want to use the jQuery dialog, your delete button's function will need to have code that submits the form, maybe by putting some ID in a hidden field and calling click() on a hidden button.

The dialog prevents the default actions from happening, so you need to submit or perform the action in the Delete button function.
So returning false or true doesn't do what you expect.
You need to add more to this (AJAX to send to the server or something similar)
"Delete": function ()
{
<add call to function to send data to server>
$(this).dialog("close");
},

Please change the delete button to Confirm .
for use this code "Confirm": function () instead of "Delete": function ()

jQuery UI Dialog with Confirmation

I have a jQuery UI dialog that gets a line of text. If this text is not contained in a localStorage dictionary, I insert it into the dictionary. If it is present, I want to give the user the option not to overwrite the existing entry in the "ok" handler.
Because jQuery UI dialogs are stateful and persist across multiple calls unless explicitly removed (AFAICT), I'm not seeing a clear path to presenting the "are you sure you want to nuke your previous entry?" alert without resorting to ... uh ... alert.
The question, succinctly stated: Can you create a confirmation box from inside a jQuery UI Dialog?
Thanks.

I have not used jQuery UI Dialog, but you can always create your own html elements and do whatever you wish with them, including layering them on top of the jQuery dialog.

I guess you could have googled something to find these links:
Anyways have it and make fun:

Cheers!!!

Ok, it turned out the best way I found to handle this was using closures. Like this (pseudo-code):
getThingieName: handler(function() {
var $dialog;
$dialog = $('<div id="thingie-name-dialog" class="ui-widget"></div>').html("<p>Enter a name for this thingie</p>\n<input type=\"text\" id=\"dlg-thingie-name\" style=\"width: 80%\" />").dialog({
autoOpen: false
}, {
title: 'enter a name',
modal: true,
buttons: {
Add: function() {
var value = $('#dlg-thingie-name').val();
$(this).dialog('close');
$('#thingie-name-dialog').remove();
return handler(value); // <= closure to handle the onAdd
},
Cancel: function() {
$(this).dialog('close');
return $('#thingie-name-dialog').remove();
}
}
});
return $dialog.dialog('open');
}),
getConfirmation: function(message, handler) {
var $dialog;
$dialog = $('<div id="confirmation-dialog" class="ui-widget"></div>').html("<p>" + message + "</p>").dialog({
autoOpen: false
}, {
title: 'confirm overwrite',
modal: true,
buttons: {
Ok: function() {
$(this).dialog('close');
$('#confirmatio-dialog').remove();
return handler(true); // <= closure to handle onOk
},
Cancel: function() {
$(this).dialog('close');
$('#Thingie-name-dialog').remove();
return handler(false); // <= closure to handle onCancel
}
}
});
return $dialog.dialog('open');
}
// Calling sequence
Snippets.getSnippetName(function(value) {
if (value == null) return false;
if (localStorage.getItem(value)) {
getConfirmation("This thingie, " + value + ", already exists. Overwrite?", function(response) {
if (response) return localStorage.setItem(value, snippet);
});
} else {
localStorage.setItem(value, snippet);
}
}
This may not be the optimal code, but it does make the triggering of the dialogs dependent on the button push by embedding them in the handlers.

How do I get a JQuery statement to wait until it's completed before continuing?>

Firstly, I'm new at Javascript / Jquery so it might be a stupid question...
I'm using the dialog box that is in the JQuery UI collection. I have a button that when clicked, it either shows a confirm box or an alert box. My code is like below...
function checkfn() {
if (document.getElementById('<%=HomeInstSelected.ClientID%>').value == 'False') {
var dialogResult = false;
$("#dialog-confirm").dialog({
resizable: false,
height: 140,
modal: true,
buttons: {
Continue: function () {
dialogResult = true;
$(this).dialog("close");
},
Cancel: function () {
$(this).dialog("close").slideUp();
}
}
});
// alert just debug code!
alert(dialogResult);
return dialogResult;
}
else {
$("#dialog-HomeInstitutionPrompt").dialog({
height: 140,
modal: true
});
}
}
My problem is in the confirm part, it seems the confirm box is not waiting for me to hit Continue or Cancel - it's just going straight to the alert part and returning dialogResult = false.
Is it possible to halt execution of until after I've run the $('#dialog-confirm') command?
Alternatively, is it possible to return true for the checkfn() function, in the Continue function? That way, I will not need a dialogResult var at all?

I haven't used the .dialog in jQuery UI before, but, in general with jQuery, functions are run asynchronously. What this means is that you need to put the code that you want run in the Continue function.
One possibility is to send a success/cancel function to checkfn that you would call from the Continue and Cancel functions.
function checkfn(success, cancel) {
if (document.getElementById('<%=HomeInstSelected.ClientID%>').value == 'False') {
var dialogResult = false;
$("#dialog-confirm").dialog({
resizable: false,
height: 140,
modal: true,
buttons: {
Continue: function () {
if(success) success();
$(this).dialog("close");
},
Cancel: function () {
if(cancel) cancel();
$(this).dialog("close").slideUp();
}
}
});
}
You can call the function like this:
checkfn(function () {
alert('success!');
}, function () {
alert('failure!');
});

Just put everything you want to do inside "Continue" and "Cancel" button definitions. So, you will not need a dialogResult and alert will hit when it is needed.
if (document.getElementById('<%=HomeInstSelected.ClientID%>').value == 'False') {
var dialogResult = false;
$("#dialog-confirm").dialog({
resizable: false,
height: 140,
modal: true,
buttons: {
Continue: function () {
alert('Dialog result is true. I can do whatever I want here');
$(this).dialog("close");
},
Cancel: function () {
alert('Cancel is clicked. I should go on my life');
$(this).dialog("close").slideUp();
}
}
});
}
else {
$("#dialog-HomeInstitutionPrompt").dialog({
height: 140,
modal: true
});
}
-- You can't return a value for your function, because after initialization of the function, the code goes on. You need to fill Continue button definition.

This is something I struggled with when I started too, The code doesn't run as it reads on the page. When you call the dialog function it executes asynchronously. The continue and cancel functions are bound to the click actions on the buttons, meanwhile the code below the dialog function runs without waiting for the events.
Long story short the result needs to happen in the cancel and continue callbacks.
Problem is you're trying to return a boolean value when you should really pass the resulting functions in instead. Alot of things in jquery and javascript in general work that way. Thankfully the language provides the ability to program in this way.
function checkfn( resultfn(boolval) ) {
if (document.getElementById('<%=HomeInstSelected.ClientID%>').value == 'False') {
var dialogResult = false;
$("#dialog-confirm").dialog({
resizable: false,
height: 140,
modal: true,
buttons: {
Continue: function () {
resultfn.call( this, true );
$(this).dialog("close");
},
Cancel: function () {
resultfn.call( this, false );
$(this).dialog("close").slideUp();
}
}
});
}
Put the if statement in "resultfn"

I had a similar frustrating problem where the jQuery dialog box would submit a form before the user had a chance to choose Yes or No.
Example HTML:
<form id="myForm" method="POST" action="/Where/To/Go">
<input type="submit" value="Submit" onclick="submitForm()"/>
</form>
And jQuery:
function submitForm() {
$('<div title="Submit Form>Are you sure you wish to submit the form?</div>').dialog({
modal: true,
buttons: [
{
text: "Yes",
click: function () {
$('#myForm').submit();
$(this).dialog("close");
}
}, {
text: "No",
click: function () {
$(this).dialog("close");
}
}
]
});
}
To fix the issue I changed the button from a submit type to a button type which stopped it submitting and triggering the jQuery dialog at the same time:
<input type="button" value="Submit" onclick="submitForm()"/>
