How to disable scrolling and re-enable scrolling on a mobile touch screen device

This is not so much of a question as it is an solution to the question.

It was difficult find a solution until I stumbled across the answer in added by hallodom (How to disable scrolling temporarily?) which was responding to a slightly different problem.

I wanted to explicitly document an answer to the problem. Other solutions are most welcome and would add to the conversation.

hallodom's solution was:

For mobile devices, you'll need to handle the touchmove event:

$('body').bind('touchmove', function(e){e.preventDefault()})

And unbind to re-enable scrolling. Tested in iOS6 and Android 2.3.3

$('body').unbind('touchmove')

I used hallodom's solution by simply attaching them to functions called when an object in my DOM was clicked:

    $('body').on('click', 'button', function(e){
        if($(this).prop('checked')){
             disable_scroll();
        }else{
             enable_scroll();
        }
    });

    function disable_scroll() {
         $('body').bind('touchmove', function(e){e.preventDefault()});
    }

    function enable_scroll() {
        $('body').unbind('touchmove');
    }

Try this code :

var scroll = true

$(document).bind('touchmove', function(){
    scroll = false
}).unbind('touchmove', function(){
    scroll = true
})

$(window).scroll(function() {
    if ($('button').is(':checked') && scroll == false) {
        $(document).scrollTop(0);
    }
})
