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;"><a href="/Booking.aspx/Cancel/15">cancel</a></td>
<td style="width: 80px;"><a href="/Booking.aspx/Change/15">change</a></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;"><a href="/Booking.aspx/Cancel/10">cancel</a></td>
<td style="width: 80px;"><a href="/Booking.aspx/Change/10">change</a></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
<a href="/Booking.aspx/Cancel/10">cancel</a>
with
<a href="#" onclick="ShowDialog(10)">cancel</a>
.
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?
Solution 1:
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);
}
}
});
Solution 2:
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...
