Question

I\'ve created a small HTML5 web application for my company.

This application displays a list of items and everything works fine.

The application is mainly us

AngularJS

I have successfully disabled it with this AngularJS directive:

//Prevents "pull to reload" behaviour in Chrome. Assign to child scrollable elements.
angular.module('hereApp.directive').directive('noPullToReload', function() {
    'use strict';

    return {
        link: function(scope, element) {
            var initialY = null,
                previousY = null,
                bindScrollEvent = function(e){
                    previousY = initialY = e.touches[0].clientY;

                    // Pull to reload won't be activated if the element is not initially at scrollTop === 0
                    if(element[0].scrollTop <= 0){
                        element.on("touchmove", blockScroll);
                    }
                },
                blockScroll = function(e){
                    if(previousY && previousY < e.touches[0].clientY){ //Scrolling up
                        e.preventDefault();
                    }
                    else if(initialY >= e.touches[0].clientY){ //Scrolling down
                        //As soon as you scroll down, there is no risk of pulling to reload
                        element.off("touchmove", blockScroll);
                    }
                    previousY = e.touches[0].clientY;
                },
                unbindScrollEvent = function(e){
                    element.off("touchmove", blockScroll);
                };
            element.on("touchstart", bindScrollEvent);
            element.on("touchend", unbindScrollEvent);
        }
    };
});

It's safe to stop watching as soon as the user scrolls down, as the pull to refresh has no chance of being triggered.

Likewise, if scrolltop > 0, the event won't be triggered. In my implementation, I bind the touchmove event on touchstart, only if scrollTop <= 0. I unbind it as soon as the user scrolls down (initialY >= e.touches[0].clientY). If the user scrolls up (previousY < e.touches[0].clientY), then I call preventDefault().

This saves us from watching scroll events needlessly, yet blocks overscrolling.

jQuery

If you are using jQuery, this is the untested equivalent. element is a jQuery element:

var initialY = null,
    previousY = null,
    bindScrollEvent = function(e){
        previousY = initialY = e.touches[0].clientY;

        // Pull to reload won't be activated if the element is not initially at scrollTop === 0
        if(element[0].scrollTop <= 0){
            element.on("touchmove", blockScroll);
        }
    },
    blockScroll = function(e){
        if(previousY && previousY < e.touches[0].clientY){ //Scrolling up
            e.preventDefault();
        }
        else if(initialY >= e.touches[0].clientY){ //Scrolling down
            //As soon as you scroll down, there is no risk of pulling to reload
            element.off("touchmove");
        }
        previousY = e.touches[0].clientY;
    },
    unbindScrollEvent = function(e){
        element.off("touchmove");
    };
element.on("touchstart", bindScrollEvent);
element.on("touchend", unbindScrollEvent);

Naturally, the same can also be achieved with pure JS.
