JQuery Dialog Binding Event to Button - javascript

I am having some trouble with jQuery. I want to have a dialog box appear when the user clicks a link to delete something and prompt them to be sure that they actually want to delete it. The dialog box appears fine however I don't see a way to get the url of the link when user clicks the "Yes" button. I tried using the event.relatedTarget property to get the url of the a tag but it is null. Does anyone know how to do this?
Code
<div id="dialog" title="Delete Run">
<p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 0 0;"></span>Are you sure you want to delete that run?</p>
</div>
$(document).ready(function() {
$('#dialog').dialog({
autoOpen: false,
width: 400,
modal: true,
draggable: false,
resizable: false,
buttons: {
"Yes": function(event) {
//Go to the url in $("a.delete")
},
"No": function() {
$(this).dialog("close");
}
}
});
$("a.delete").click(function(){
var url = $(this).attr("href");
$('#dialog').dialog('open');
return false;
});
});

<div id="dialog" title="Delete Run">
<p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 0 0;"></span>Are you sure you want to delete that run?</p>
</div>
$(document).ready(function() {
$('#dialog').dialog({
autoOpen: false,
width: 400,
modal: true,
draggable: false,
resizable: false,
buttons: {
"Yes": function(event) {
var url = $(this).data('url');
window.location = url;
},
"No": function() {
$(this).dialog("close");
}
}
});
$("a.delete").click(function(){
$('#dialog').data('url', $(this).attr("href"));
$('#dialog').dialog('open');
return false;
});
});
A little bit of guessing, as there is no element a.delete in your code ?
Using jQuery's data() is usually a better option than global variables.

You can declare the url var at the start of the document ready in order to access that variable in any of your functions. So first do var url; after (document).ready, then remove the var declaration from the delete's click function and finally set the window location to that variable like so: window.location.href = url; You'll get something like this in the end:
$(document).ready(function() {
var url;
$('#dialog').dialog({
autoOpen: false,
width: 400,
modal: true,
draggable: false,
resizable: false,
buttons: {
"Yes": function(event) {
window.location.href = url;
},
"No": function() {
$(this).dialog("close");
}
}
});
$("a.delete").click(function(){
url = $(this).attr("href");
$('#dialog').dialog('open');
return false;
});
});
I've set up an example with your code here: http://jsfiddle.net/dGETj/

Why is html call to js function getting html can't find variable error?

I have js/jquery dialog that has an some html input buttons that allow the user to select a color. The button when clicked should call the javascript function changeColor. I have reduced the code to a minimal set, yet when clicking the one of the color buttons I get an html "Reference Error: can't find variable: changeColor" error. Not sure what I am missing.
function changeColor(themeColor) {
var a = 1;
}
$('#change-theme').on('click', function() {
$('#theme').dialog({
width: 500,
resizable: false,
show: 'slide',
autoOpen: false,
modal: true,
buttons: [{
text: "Save",
tabIndex:-1,
'class':'dialog3_buttons',
click: function(event) {
$(this).dialog("close");
return true;
}
}, {
text: "Cancel",
tabIndex:-1,
'class':'dialog3_buttons',
click: function(event) {
$(this).dialog("close");
return false;
}
}]
})
.height("auto");
$("#theme").dialog( "option", "title", "Theme Picker - click a color to preview" );
$("#theme").html(
"<input type='button' class='color-button white-btn' id='color-button' name='white' onclick='javascript:changeColor()' >" +
"<input type='button' class='color-button black-btn' id='color-button' name='black' onclick='javascript:changeColor()' >"
);
$('#theme').dialog('open');
});
You have to assign the function to a globally available scope if you want to call it from html like you do in your example
Add this line to your code
window.changeColor = changeColor;
See this working example https://jsfiddle.net/09ghrhap/1/
I guess you need to place the function into the <head></head>

jQuery ("#dialog").dialog('close') not working with button on separate view

I have an ASP.NET view in an MVC project in which I am trying to create a pop-up dialog to create data. There is another view that gets loaded and that view has a button with the id "btncancel_create". I cannot get that button to close the dialog. I am using jQuery 2.1.3 and jQuery UI 1.11.4.
Here is the code for the button:
<input type="button" value="Cancel" id="btncancel_create" />
And here is the view:
$(document).ready(function () {
//alert("Document is ready");
var url = "";
$("#dialog-create").dialog({
title: 'Create User',
autoOpen: false,
resizable: false,
width: 400,
show: { effect: 'drop', direction: "up" },
modal: true,
draggable: true,
open: function (event, ui) {
$(".ui-dialog-titlebar-close").hide();
$(this).load(url);
}
});
$("#lnkCreate").on("click", function (e) {
url = $(this).attr('href');
$("#dialog-create").dialog('open');
return false;
});
//$("#btncancel_create").on("click", function (e) {
// $("#dialog-create").dialog("close");
// return false;
//});
$("#dialog-create").button("#btncancel_create").click(function (e) {
alert("btncancel_create was clicked");
$("#dialog-create").dialog('close');
return false;
});
});
<div id="dialog-create" style="display: none"></div>
<p>#Html.ActionLink("Create New", "Create", null, new { id = "lnkCreate" })</p>
As you can see, I tried something else which didn't work, which is commented out. The uncommented button click function does return the alert, but does not close the dialog. Thanks in advance for your help, and please let me know if you need any more information.
Instead of
$("#btncancel_create").on("click", function (e) {...
(in my commented out code above)
it should be
$(document).on("click", "#btncancel_create", function (e) {....

Inside the jquery popup dialog asp button doesn't fire event

I have following snippets for popup dialog
$(document).ready(function () {
$('a#MainEdit').live('click', function (e) {
var page = $(this).attr("href")
$.fx.speeds._default = 900;
var $dialog = $('<div id="Editdialoge"></div>')
.html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
.dialog({
autoOpen: false,
modal: true,
height: 580,
width: 700,
resizable: false,
show: "fade",
title: 'Edit Employee Details',
open: function () {
$(":button:contains('Close')").hide();
$('.ui-dialog-buttonpane').hide();
},
buttons: {
"Close": function () { $dialog.dialog('close'); }
},
close: function (event, ui) {
__doPostBack('<%=updAccountObject.ClientID %>', '');
}
});
$dialog.dialog('open');
e.preventDefault();
});
This is my button
<asp:Button ID="btnAddEmployee" runat="server" Text="Add" CssClass="pms_btn" OnClick="btnSubmit_Click">
Button can not fire the click() event.
I need help to fire the server event.
Please make your question more clear.
Be any problem(ID or jquery), I guess this will fix your problem.
Don't use live function, it has been deprecated now.
Instead, use this line:
$('a#MainEdit').on('click', function (e) {
or
$(document).on("click", "a#MainEdit", function() {
I hope this works for you.
For buttons, i prefer to use:
$('<%=updAccountObject.ClientID %>').click();

Return value of jquery UI dialog Box

You may find solution over this in many posts(Post 1 , Post2 ), but their solution not working for me.
Here is the normal jquery dialog box written by me.
$("#dialog").dialog({
autoOpen:false,
buttons:{
"ok":function(){
$(this).dialog("close");
return true;
},
"cancel":function(){
$(this).dialog("close"); return false;
}
}
});
I will open the dialogbox with code:
var returnVal=$("#dialog").dialog("open");
I need to return false,if user clicks 'cancel' and return true if user clicks 'ok'.
var returnVal=$("#dialog").dialog("open");
I NEED returnVal to return boolean value(true/false), but it returns javascript object.
You cannot return something from the OK / cancel functions as they are essentially event handlers that are only processed upon the click of a button.
Use a separate function to process the result :
$mydialog = $("#dialog").dialog({
autoOpen: false,
buttons: {
"ok": function() {
$(this).dialog("close");
processResult(true);
},
"cancel": function() {
$(this).dialog("close");
processResult(false);
}
}
});
$mydialog.dialog("open");
function processResult(result) {
alert(result);
}
Working example : http://jsfiddle.net/nz2dH/
I have implement Yes/No confirmation dialog with custom message and callback function like this. This is useful, if you like to use the same dialog for various purposes.
<script type="text/javascript">
// prepare dialog
$(function () {
$("#confirm-message-dialog").dialog({
autoOpen: false,
modal: true,
closeOnEscape: false,
buttons: {
Yes: function () {
$(this).dialog("close");
$(this).data("callback")(true);
},
No: function () {
$(this).dialog("close");
$(this).data("callback")(false);
}
}
});
});
// open dialog with message and callback function
function confirmMessageDialog (message, callback) {
$('#confirm-message-dialog-message').text(message);
$('#confirm-message-dialog').data("callback", callback).dialog("open");
};
</script>
<!-- The dialog content -->
<div id="confirm-message-dialog" title="Warning">
<p id="confirm-message-dialog-message"></p>
</div>
Hope that this helps others as well :)

Passing data to a jQuery UI Dialog

I'm developing an ASP.Net MVC site and on it I list some bookings from a database query in a table with an ActionLink to cancel the booking on a specific row with a certain BookingId like this:
My bookings
<table cellspacing="3">
<thead>
<tr style="font-weight: bold;">
<td>Date</td>
<td>Time</td>
<td>Seats</td>
<td></td>
<td></td>
</tr>
</thead>
<tr>
<td style="width: 120px;">2008-12-27</td>
<td style="width: 120px;">13:00 - 14:00</td>
<td style="width: 100px;">2</td>
<td style="width: 60px;">cancel</td>
<td style="width: 80px;">change</td>
</tr>
<tr>
<td style="width: 120px;">2008-12-27</td>
<td style="width: 120px;">15:00 - 16:00</td>
<td style="width: 100px;">3</td>
<td style="width: 60px;">cancel</td>
<td style="width: 80px;">change</td>
</tr>
</table>
What would be nice is if I could use the jQuery Dialog to popup a message asking if the user is sure he wants to cancel the booking. I have been trying get this to work but I keep getting stuck on how to create a jQuery function that accepts parameters so that I can replace the
cancel
with
cancel.
The ShowDialog function would then open the dialog and also pass the paramter 10 to the dialog so that if the user clicks yes then It will post the href: /Booking.aspx/Change/10
I have created the jQuery Dialog in a script like this:
$(function() {
$("#dialog").dialog({
autoOpen: false,
buttons: {
"Yes": function() {
alert("a Post to :/Booking.aspx/Cancel/10 would be so nice here instead of the alert");},
"No": function() {$(this).dialog("close");}
},
modal: true,
overlay: {
opacity: 0.5,
background: "black"
}
});
});
and the dialog itself:
<div id="dialog" title="Cancel booking">Are you sure you want to cancel your booking?</div>
So finally to my question: How can I accomplish this? or is there a better way of doing it?
jQuery provides a method which store data for you, no need to use a dummy attribute or to find workaround to your problem.
Bind the click event:
$('a[href*=/Booking.aspx/Change]').bind('click', function(e) {
e.preventDefault();
$("#dialog-confirm")
.data('link', this) // The important part .data() method
.dialog('open');
});
And your dialog:
$("#dialog-confirm").dialog({
autoOpen: false,
resizable: false,
height:200,
modal: true,
buttons: {
Cancel: function() {
$(this).dialog('close');
},
'Delete': function() {
$(this).dialog('close');
var path = $(this).data('link').href; // Get the stored result
$(location).attr('href', path);
}
}
});
You could do it like this:
mark the <a> with a class, say "cancel"
set up the dialog by acting on all elements with class="cancel":
$('a.cancel').click(function() {
var a = this;
$('#myDialog').dialog({
buttons: {
"Yes": function() {
window.location = a.href;
}
}
});
return false;
});
(plus your other options)
The key points here are:
make it as unobtrusive as possible
if all you need is the URL, you already have it in the href.
However, I recommend that you make this a POST instead of a GET, since a cancel action has side effects and thus doesn't comply with GET semantics...
In terms of what you are doing with jQuery, my understanding is that you can chain functions like you have and the inner ones have access to variables from the outer ones. So is your ShowDialog(x) function contains these other functions, you can re-use the x variable within them and it will be taken as a reference to the parameter from the outer function.
I agree with mausch, you should really look at using POST for these actions, which will add a <form> tag around each element, but make the chances of an automated script or tool triggering the Cancel event much less likely. The Change action can remain as is because it (presumably just opens an edit form).
I have now tried your suggestions and found that it kinda works,
The dialog div is alsways written out in plaintext
With the $.post version it actually works in terms that the controller gets called and actually cancels the booking, but the dialog stays open and page doesn't refresh.
With the get version window.location = h.ref works great.
Se my "new" script below:
$('a.cancel').click(function() {
var a = this;
$("#dialog").dialog({
autoOpen: false,
buttons: {
"Ja": function() {
$.post(a.href);
},
"Nej": function() { $(this).dialog("close"); }
},
modal: true,
overlay: {
opacity: 0.5,
background: "black"
}
});
$("#dialog").dialog('open');
return false;
});
});
Any clues?
oh and my Action link now looks like this:
<%= Html.ActionLink("Cancel", "Cancel", new { id = v.BookingId }, new { #class = "cancel" })%>
Looking at your code what you need to do is add the functionality to close the window and update the page. In your "Yes" function you should write:
buttons: {
"Ja": function() {
$.post(a.href);
$(a). // code to remove the table row
$("#dialog").dialog("close");
},
"Nej": function() { $(this).dialog("close"); }
},
The code to remove the table row isn't fun to write so I'll let you deal with the nitty gritty details, but basically, you need to tell the dialog what to do after you post it. It may be a smart dialog but it needs some kind of direction.
After SEVERAL HOURS of try/catch I finally came with this working example, its working on AJAX POST with new rows appends to the TABLE on the fly (that was my real problem):
Tha magic came with link this:
remove
remove
remove
This is the final working with AJAX POST and Jquery Dialog:
<script type= "text/javascript">/*<![CDATA[*/
var $k = jQuery.noConflict(); //this is for NO-CONFLICT with scriptaculous
function removecompany(link){
companyid = link.id.replace('remove_', '');
$k("#removedialog").dialog({
bgiframe: true,
resizable: false,
height:140,
autoOpen:false,
modal: true,
overlay: {
backgroundColor: '#000',
opacity: 0.5
},
buttons: {
'Are you sure ?': function() {
$k(this).dialog('close');
alert(companyid);
$k.ajax({
type: "post",
url: "../ra/removecompany.php",
dataType: "json",
data: {
'companyid' : companyid
},
success: function(data) {
//alert(data);
if(data.success)
{
//alert('success');
$k('#companynew'+companyid).remove();
}
}
}); // End ajax method
},
Cancel: function() {
$k(this).dialog('close');
}
}
});
$k("#removedialog").dialog('open');
//return false;
}
/*]]>*/</script>
<div id="removedialog" title="Remove a Company?">
<p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>
This company will be permanently deleted and cannot be recovered. Are you sure?</p>
</div>
This work for me:
SPOSTA
function sposta(id) {
$("#sposta").data("id",id).dialog({
autoOpen: true,
modal: true,
buttons: { "Sposta": function () { alert($(this).data('id')); } }
});
}
When you click on "Sposta" in dialog alert display 100
Ok the first issue with the div tag was easy enough:
I just added a style="display:none;" to it and then before showing the dialog I added this in my dialog script:
$("#dialog").css("display", "inherit");
But for the post version I'm still out of luck.
Just give you some idea may help you, if you want fully control dialog, you can try to avoid use of default button options, and add buttons by yourself in your #dialog div. You also can put data into some dummy attribute of link, like Click. call attr("data") when you need it.
A solution inspired by Boris Guery that I employed looks like this:
The link:
<a href="#" class = "remove {id:15} " id = "mylink1" >This is my clickable link</a>
bind an action to it:
$('.remove').live({
click:function(){
var data = $('#'+this.id).metadata();
var id = data.id;
var name = data.name;
$('#dialog-delete')
.data('id', id)
.dialog('open');
return false;
}
});
And then to access the id field (in this case with value of 15:
$('#dialog-delete').dialog({
autoOpen: false,
position:'top',
width: 345,
resizable: false,
draggable: false,
modal: true,
buttons: {
Cancel: function() {
$(this).dialog('close');
},
'Confirm delete': function() {
var id = $(this).data('id');
$.ajax({
url:"http://example.com/system_admin/admin/delete/"+id,
type:'POST',
dataType: "json",
data:{is_ajax:1},
success:function(msg){
}
})
}
}
});
i hope this helps
$("#dialog-yesno").dialog({
autoOpen: false,
resizable: false,
closeOnEscape: false,
height:180,
width:350,
modal: true,
show: "blind",
open: function() {
$(document).unbind('keydown.dialog-overlay');
},
buttons: {

$(this).dialog("close");
var dir = $(this).data('link').href;
var arr=dir.split("-");
