overflow-x: hidden is breaking jquery scroll event

2019-02-16 07:45发布

I am having an issue where setting overflow-x: hidden on the html and body elements is preventing the jquery scroll event from firing.

CSS:

html, body {
  overflow-x: hidden;
}

JS:

$(function(){
  $(window).on("scroll", function(e){
    console.log("scrolling");    
  });
});

http://jsfiddle.net/r7Fqq/6/

Try it for yourself: Comment out overflow-x: hidden and pop open your console. You should see "scrolling" logged as you scroll up and down the html box. Comment it back in and the scroll event is silent.

Does anyone know why this is happening? I'm aware that when you set overflow to hidden it disables scrolling, but it should only do it for the axis that you are setting (x only in this case). Thanks in advance for any help.

$(function() {
    $(window).bind('mousewheel', function(event, delta) {
        console.log("mousewheel");
        return false;
    });
});

Set body {height: 100%;} in css. It would work then. You may want to apply overflow property on a div than to whole body and then change JS code accordingly. Setting a overflow property on body takes away its scrolling ability. Another solution can be using Jquery wheel event as described in this post- (https://stackoverflow.com/a/8378946/5348972).

Had the same problem. Solution is to remove the overflow-x: hidden from the html element and leave it only on the body element and it should work.

I have also found this to be the case. When we added:

body {
  overflow-x: hidden;
}

all window.addEventListener('scroll') events stopped triggering. I believe this it is because the scroll event is not moved to the document.body. When I change the eventListener to document.body.addEventListener('scroll'), things start working again. The interesting thing is that my event.bubbles boolean is false. From what I read the scroll event should bubble to the window.

Solution

change

window.addEventListener('scroll', () => console.log('MEOW'))

to

document.body.addEventListener('scroll', () => console.log('MEOW'))
