Passing data to a jQuery UI Dialog - javascript

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: {
"Delete": function() {
$(this).dialog("close");
var dir = $(this).data('link').href;
var arr=dir.split("-");
delete(arr[1]);
},
"Cancel": function() {
$(this).dialog("close");
}
}
});
Delete

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>

How to have the JQuery version of tinyMCE open multiple text areas in popups when clicking on a table cell?

OK, so I'm trying to create a template that will be used for providing information for multiple scenarios in the same format. To do this, I have a table set up that will show the information, and when you click on one of the cells ('s specifically), it will place the inner HTML into a text area that comes up in a jQuery modal dialog box. This text area is then turned into a TinyMCE instance for editing (using Tiny MCE javascript version 4.3.2). However, with my current code, this only works the first time. After that, no matter what cell is clicked, I get a popup that shows as empty, though it has the proper HTML inside when I run inspect element.
I have seen similar things in previous questions, but one of them only wanted to use jQuery to have the popup work, which I've done, and the other was not using the jQuery version, and the solution code did not work with this version, but it seems that it simply closed out the instance when the dialog was closed so that it could be redone on the next text area. Also, I'm using a custom CSS for looks, but the jQuery Start scheme is the closest available scheme, if you want it to look pretty while you troubleshoot.
Edit: To clarify, I am not trying to open multiple runs simultaneously, they should open one at a time.
Code:
<head>
<script src="assetts/jquery-1.10.2.js"></script>
<script src="assetts/jquery-ui.min.js"></script>
<script src="tinymce/js/tinymce/jquery.tinymce.min.js"></script>
<script src="tinymce/js/tinymce/tinymce.min.js"></script>
<script type="text/javascript">
$(window).load(function () {
$('td').click(function (event) {
var currentId = this.id;
var currentHTML = this.innerHTML;
alert(currentId);
$(function () {
$("<div id=\"editmodal-diag\"></div>").dialog({
title: 'Edit',
modal: true,
buttons: {
Ok: function () {
var t = "#" + currentId;
alert(t);
$(this).dialog("close"); $("#editmodal-diag").remove();
tinymce.execCommand('mceRemoveControl', true, '#editmodal-diag-text');
},
Cancel: function () {
$(this).dialog("close"); $("#editmodal-diag").remove();
tinymce.execCommand('mceRemoveControl', true, '#editmodal-diag-text');
}
}
});
})
$('#editmodal-diag').append("<textarea id=\"editmodal-diag-text\">" + currentHTML + "</textarea>");
$('#editmodal-diag-text').empty;
$('#editmodal-diag-text').tinymce({ plugins: 'link' });
});
</script>
</head>
<body>
<table width="75%>
<tr>
<th>Header text</th>
</tr>
<tr>
<td>Information panel 1</td>
<td>Information panel 2</td>
</tr>
</table>
</body>
Thanks in advance.
After more digging, I found TinyMCE 4 - remove() or destroy(), in which I found that the tinymce control needed to be removed with:
tinymce.execCommand('mceRemoveControl', true, 'editmodal-diag-text');
tinymce.remove();
to completely remove the current editor, before being reinitialized by:
tinymce.execCommand('mceAddControl', true, 'editmodal-diag-text');
$('#editmodal-diag-text').tinymce({ plugins: 'link'});
This only needed to be done after the first box came up. I used a Boolean variable to check this. Complete function:
var tinyRun = false;
$(window).load(function () {
setTimeout(function () {
$('td').click(function (event) {
var currentId = this.id;
var currentHTML = this.innerHTML;
alert(currentId);
$(function () {
$("<div id=\"editmodal-diag\"><textarea id=\"editmodal-diag-text\"></textarea></div>").dialog({
title: 'Edit',
modal: true,
buttons: {
Ok: function () {
var t = "#" + currentId;
alert(t);
$(this).dialog("close"); $("#editmodal-diag").remove();
tinymce.execCommand('mceRemoveControl', true, 'editmodal-diag-text');
tinymce.remove();
},
Cancel: function () {
$(this).dialog("close"); $("#editmodal-diag").remove();
tinymce.execCommand('mceRemoveControl', true, 'editmodal-diag-text');
tinymce.remove();
}
}
});
})
setTimeout(function () {
$('#editmodal-diag-text').text(currentHTML);
if (!tinyRun) {
$('#editmodal-diag-text').tinymce({ plugins: 'link' });
tinyRun = true;
}
else {
tinymce.execCommand('mceAddControl', true, 'editmodal-diag-text');
$('#editmodal-diag-text').tinymce({ plugins: 'link' });
}
}, 250);
});
}, 250);
}

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) {....

Multiple buttons call JQuery, need to know which one was clicked

I have multiple buttons which can call the same JQuery function. Example of html:
<tr><td>...</td>
<td><button class="modify" name="8">Modify</button></td>
</tr>
<tr><td>...</td>
<td><button class="modify" name="9">Modify</button></td>
</tr>
and so on...
And my JQuery function:
$(function() {
var id = $("button").attr("name");
$("#dialog").dialog({
autoOpen: false,
height: 250,
width: 240,
modal: true,
buttons: {
"Submit": function() {
$( this ).dialog( "close" );
$.ajax({
url: 'my_http',
type: 'POST',
data: $my_data,
});
},
Cancel: function () {
$(this).dialog("close");
}
}
});
$(".modify").click(function () {
$("#dialog").dialog("open");
}
});
As you can see I need to now which button was clicked (I retrieve it's name at the beginning of the dialog function). But since its "clickability" is determined by the class, not id, I get the first id in the list (8 in this case, even though the 9th was clicked).
How can I know which one was clicked? If I use classes, I do not know ids (names), if I use ids, how can I know that it was clicked?
Inside the click() method:
$(".modify").click(function () {
/* 'this' is the clicked DOM node,
'$(this)' is the clicked DOM node wrapped in a jQuery object. */
var clickedButtonName = this.name;
/* or $(this).prop('name'), but don't use jQuery to access a property that
can be returned by the DOM API, it's needlessly expensive. */
$("#dialog").dialog("open");
}
You can use the first parameter of the click function like so:
Click here for live demo!
$(".modify").click(function (e) {
console.log(e.target);
});

how to retrieve href value for an onclick event based on "class" selector in Javascript?

I have
Click to proceed
and following javascript. When I click on above link it displays the dialog box with 2 buttons. "return false;" stops the default event of link tag. But I need the functionality in which when I click "Yes, delete" to take me to other page by choosing href value of a onclicked anchor. I tried alert($(this).attr('id')); (as I thought I could pick up HREF value using "this.attr('href')") but it displays "dialog".
How do I make it work so that when I click on a link having class name "confirm_delete" it displays me dialog, and if I click cancel it stays on the page otherwise takes me to page according to href value.
$(".confirm_delete").click(function(){
$('<div id="dialog">Are you sure you want to delete?</div>').appendTo('body');
$("#dialog").dialog({
bgiframe: true, resizable: false, height:140, modal: true,
overlay: {
backgroundColor: '#000', opacity: 0.5
},
buttons: {
'Yes, Delete all items in recycle bin': function() {
$(this).dialog('close');
$(this).remove();
alert($(this).attr('id'));
},
Cancel: function() {
$(this).dialog('close');
$(this).remove();
}
}
});
return false;
});
Thank you.
First off: try not to use underscores in class names. I've read somewhere they may cause problemsn...
Well, here:
$('a.confirm-delete').click( function(event) {
if( !confirm('are you sure you want to go?') ) return false;
});
here I've usedd the javascript confirm dialog. You can easily replace that with a jquery modal dialog.
jrh
OK, I can retrieve value of HREF
by var url = $(this).attr('href'); just after the $(".confirm_delete").click(function(){
line. It gives me "test.php?id=123" Only thing left is create/retrieve full url and redirecting to that url.
Thanks
This should do the trick:
$(".confirm_delete").click(function(){
var $delete = $(this);
...
$("#dialog").dialog({
...
buttons: {
'Yes, Delete all items in recycle bin': function() {
$(this).dialog('close');
$(this).remove();
alert($delete.attr('id'));
}
}
});
return false;
});
