问题
I am using a fancybox with plugin jquery.easydrag.js. The reason for this is to be able to drag the fancybox around.
It seems to be working fine, but the problem comes when the fancybox has scrollbars. I.e. for example when clicking on submit and not entering any fields the valdidation on screen causes scrollbars. Which is fine normally but the scrollbars causes all sorts of issues with the draggable feature so that when I am trying to click the scrollbar up and down, it actually moves the entire windows. So it seems to be confused as to what content can be moved and what to do with a scrollbar.
claimLink.fancybox({
'width': 500,
'height': 590,
'autoDimensions': false,
'onCleanup': function (e) {
var modelClaimFormId = $j(e).attr("href").replace("body", "");
var modalClaimForm = $j(modelClaimFormId);
if (!($j(modalClaimForm).valid())) {
$j(claimForm).remove();
$j(e).parents("tr").remove();
}
}
});
$j("#fancybox-wrap").easydrag(true);
EDIT :
I managed to add something for input and textareas to ignore the scrolling see below...just wondering what I can do for scrollbars.
$j("#fancybox-wrap").easydrag(true);
$j("#fancybox-wrap input,textarea").click(function(){
$j("#fancybox-wrap").dragOff();
});
$j("#fancybox-wrap input,textarea").mouseover(function () {
$j("#fancybox-wrap").dragOff();
});
$j("#fancybox-wrap input,textarea").blur(function () {
$j("#fancybox-wrap").dragOn();
});
$j("#fancybox-wrap input,textarea").mouseout(function () {
$j("#fancybox-wrap").dragOn();
});

I posted the first example about how to make fancybox draggable back in 2009 for v1.2.1. Then I posted some notes to make it work with v1.3.1 as seen here but when fancybox v1.3.4 was introduced, the easyDrag plugin was not working as smooth as with the previous versions and started behaving buggy. I didn't have the time to find a workaround ... so I just drop it.
The solution was simple though: the easyDrag plugin provides a way to set a "handler" as explained here so instead of holding and dragging the whole #fancybox-wrap container, which blocks access to the scroll bars if any, you just drag the lightbox from a specific defined element. Such handler can be appended to #fancybox-wrap selector and set it within the EasyDrag plugin using the onComplete callback API option like:
'onComplete': function(){
// append the handler on the top-left corner of fancybox
$("#fancybox-wrap").append("<button id='handler'>Drag me</button>");
// set the handler using the handler's element ID
$("#fancybox-wrap").setHandler('handler');
}
Notice that you can use any element as handler, in my example I used a html button but you may use an image if preferred. The important thing is to assign the minimum important css properties to the handler so it can be appended to the #fancybox-wrap container without issue like:
width: 80px; /* or whatever needed */
height: 24px;
position: absolute; /* important to position the handler into the fancybox wrap */
top: 0; /* top-left corner of the box but can be anywhere */
left: 0;
display: block;
z-index: 1120; /* important to be over the box */
other properties can be cosmetic.
See it working here!!!
Once you complete and submit the form, the response will be a new fancybox with scroll bars that you can use independently from the easyDrag handler.
Please feel free to analyze the code and customize it to your own needs (and don't forget to grant me the bounty ;)
UPDATE: Notice that since we are appending the handler to the #fancybox-wrap container every time we fire fancybox, then we need to remove it once we close fancybox using the onClosed callback, otherwise we will duplicate the handler if we open fancybox again with unexpected results:
'onClosed' : function() {
$("#fancybox-wrap #handler").remove();
}
I updated my DEMO too.
LAST NOTE: This solution is for fancybox v1.3.4.
I haven't tested it with v2.x but I don't see why it wouldn't work. Just make sure that you bind EasyDrag and append the handler to the .fancybox-wrap selector instead
$(".fancybox-wrap").easydrag();
You may use the afterShow callback to append the handler to it and afterClose to remove it.

Using the above solution to add a handler for the #fancybox-wrap selector along with the EasyDrag plugin using the onComplete callback API, I found this works nicely with the fancybox 1.3.4 title element to create a dragable fancybox with scroll functionality. Using the title, there is no need to remove it after close.
<script type="text/javascript" src="@Url.Content("~/fancybox/jquery.mousewheel-3.0.4.pack.js")"></script>
<script type="text/javascript" src="@Url.Content("~/fancybox/jquery.fancybox-1.3.4.pack.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.easydrag.handler.beta2.js")" type="text/javascript"></script>
<script>
//Fancybox
$(document).ready(function () {
$("#iframeVideoPop").fancybox({
'width': 890,
'height': 595,
'type': 'iframe',
'autoScale': 'false',
'hideOnContentClick': false,
'onComplete': function() {
//Style the title where and how you want it
$("#fancybox-title").css({'top':'-20px', 'bottom':'auto'});
//Set the fancybox-title as the handler
$("#fancybox-wrap").setHandler('fancybox-title');
}
});
$("#fancybox-wrap").easydrag();
}); //ready
<script>

In order to eliminate the scrollbar problem caused by combining Easydrag with Fancybox, you'll need to eliminate the scrollbars. By default, the Fancybox CSS stylesheet applies the overflow:auto rule to the element -- generated by Fancybox -- that wraps around the content displayed inside the Fancybox.
To override it, include your own CSS rule that supersedes the one that Fancybox applies to the wrapper. Place this style block in the <head> section of your web page:
<style>
/* id of the element generated and used by Fancybox as a wrapper around
the generated content. */
#fancy_ajax {
/* Use the important identifier to ensure the overflow:auto is suppressed */
overflow:none !important;
}
</style>
This will eliminate the scrollbars and allow the easy drag plugin to work smoothly.

After testing these solutions I ran into the problem with dragging an iframe. To resolve, I switched to the jQuery 1.9.1 UI plugin for dragging and created a transparent image while dragging. Remove the image after dragging to access the content. Works great with fancybox iframe and enables fast dragging over the iframe. See sample code below.
$("#iframePop").fancybox({
'width': 890,
'height': 430,
'type': 'iframe',
'autoScale': 'false',
'hideOnContentClick': false,
'onComplete': function() {
$("#fancybox-title").css({'top':'-2px', 'left':'15px', 'bottom':'auto', 'cursor':'move'});
$("#fancybox-wrap" ).draggable({ handle: "fancybox-title", iframeFix: true,
start: function(ev,ui){$("#fancybox-wrap").append("<img src='@Url.Content("~/Content/Images/transparent.png")' id='hidenImg' style='border: 1px solid black; width: 640px; height: 400px; top: 20px; position: absolute; z-index: 10000;' />")},
drag: function(ev,ui){},
stop: function(ev, ui){$("#fancybox-wrap #hidenDiv").remove()}
});
}
});
