jquery modal prevent scrolling AND prevent moving back to top of page on modal open

There are two problems that are both independently well-documented, but the solutions appear to be mutually exclusive from what I can tell.
The first is that when we open a modal, we want to be able to stop the screen from scrolling, which is prevented by doing something akin to this: disable browser scrolling while jQuery UI modal dialog is open
There is a second problem, which is that when the modal opens, the screen is forced to scroll back to the top of the page, which can be prevented by using the following: Prevent CSS Modal from scrolling to top
i.e. to solve the first issue, adding the following to body css solves the issue:
overflow:hidden;
and to solve the second issue, adding the following to body css solves the issue:
overflow:visible;
The problem I face is that I want both to be true. When the modal opens, I want the scrolling to be disabled, AND I want to have the page freeze at the place the user had scrolled to, rather than jumping back to the top. Neither of these solutions will allow both of these actions simultaneously.
Does anybody know of a solution that would solve these two at the same time?

My solution:
To prevent scroll. When open the dialog add a class to body like:
.modal-open {
overflow: hidden;
}
And remove class when close the dialog.
To prevent moving top. In jquery, in the function where you open dialog, add preventDefault

Don't propagate mouse wheel scrolling to IFRAME and its content

On my page I have iframe that contains some divs with scrollbars:
http://jsfiddle.net/gdx6L940/
The iframe's content is from another domain, so I do not have access to its content via DOM.
How can I block mouse-wheel scrolling of the iframe and its content? What I want to achieve is that mouse-wheel scroll will always scroll the parent page, even if the cursor is over the iframe.
EDIT
I made a little bit more real-world example:
http://jsfiddle.net/gdx6L940/2/
I want to prevent the inner iframe's divs (facebok feed) from scrolling with mouse wheel.
EDIT
To make sure: I do not want to disable scrollbars on IFRAME element nor block all events completely. I would like to block only mouse-scrolls, but preserving the ability to click

I believe that you can simply set another div element over the existing one and then put the transparency of that at 100%. that may not be the correct way of achieving your goal but it should work. I'll test it and make edits if necessary

I think I got to do partially what you want
use the code to prevent the browser from scrolling inside the div (that is inside you iframe)
window.addWheelListener(div_el, function(e) {
console.log(e.deltaY);
e.preventDefault();
})
the working example and addWheelListener code is in my jsfiddle here

You can catch mousewheel event
iframe.contentWindow.document.onmousewheel=function(event){
event.preventDefault();
};

Just did some more research and it would appear that what you are trying to do is just not possible to do the way you want to do it.

Internal Link Force scroll to top of page

I have some internal link which shows different content.
Everytime I click the internal links the browser scrolls to a position.
What I need to do is to force it to scroll to the top.
For example:
Click Here
It will show a certain div which is fine but I also need it to scroll to the top.
Is this possible?

Not sure of the exact methods right now, but something like this should work:
$('a').on('click', function(e) {
e.preventDefault();
// do your js stuff
$(window).scrollTop(0);
});

Do your links have JS code associated to the click event? Maybe you're stoping it's propagation and that is why they don't scroll your page.
If your link has an href value of "#" and you don't stop the propagation of the event (either by returning FALSE from your handler method or by using the stopPropagation method), then you should be set...

Sorry, the link doesn't work (if it was meant to be a link).
A little clarification--Are you trying to get the window to scroll the div to the top of the view, or have the window remain scrolled to the top of the viewport?
A link or code sample would be helpful...

If you're just trying to link to the top of the page,
Back to Top
should do the trick.

Stop page from scroll when changing page contents using Jquery

I am toggling a div using jquery. when this div appears on page my browser scroll bar goes to top, even i am on last of my page. can you help me to stop this scroll where it is even more and more divs appears on page using jquery
i shall be thank full

I assume the link which is being clicked that controls the div toggle is set as href="#". If this is the case, add preventDefault() to the jQuery click event handler to stop the link behaviour from making the page scroll to the top.
$("#myLink").click(function(e) {
e.preventDefault();
// toggle your div
});

you need to place all the divs that scroll inside another div that has a fixed height.

Set div position fixed without page jumping up

I have a modal dialog (jquery.dialog) that opens up when a user clicks on a link. I want to hide the scroll bar on the page behind the dialog, so user will not be able to use it. This works perfectly fine with the overflow:hidden except older IE browsers that mess the entire page up when doing that.
So I came up with this to make it work in the IE: I created a div that was covering the entire content of the page and set it to position:relative and width/height:100%. Then anytime, the modal dialog opens up, the position gets set to fixed. That makes the overwflow:hidden work in old IE.
Now, the other problem came up. When the user is at the bottom of the page and clicks on the links, dialog pops up, but the main page jumps up to the top.
I want the main page to stay intact if possible. How can I do so?
Thank you.
The code to show/close the dialog:
show:
$('#allContent').css({ position: "fixed" });
$('#viewJobPanel').dialog('open');
$('#allContent').css('overflow', 'hidden');
close:
$('#allContent').css('overflow', 'visible');
$('#allContent').css({ position: "relative" });
$('#viewJobPanel').dialog('destroy');
and when user clicks on the link, I have this event handlers
e.preventDefault();
e.stopPropagation();

Use a span bound to a click event instead of an anchor element to avoid the default behavior of repositioning the top of the window.
