问题:

I want to de-activate or remove the vertical scrollbar in an HTML page.
How to do that ?

Thanks.

回答1:

If you really need it...

html { overflow-y: hidden; }

回答2:

put this code in your html header:

<style type="text/css">
html {
        overflow: auto;
}
</style>

What I would try in this case is put this in the stylesheet

html, body{overflow:hidden;}

this way one disables the scrollbar, and as a cumulative effect they disable scrolling with the keyboard

Meder Omuraliev suggested to use an event handler and set scrollTo(0,0). This is an example for Wassim-azirar. Bringing it all together, I assume this is the final solution.

We have 3 problems: the scrollbar, scrolling with mouse, and keyboard. This hides the scrollbar:

       html, body{overflow:hidden;}

Unfortunally, you can still scroll with the keyboard: To prevent this, we can:

    function keydownHandler(e) {
var evt = e ? e:event;
  var keyCode = evt.keyCode;

  if (keyCode==38 || keyCode==39 || keyCode==40 || keyCode==37){ //arrow keys
e.preventDefault()
scrollTo(0,0);
}
}

document.onkeydown=keydownHandler;

The scrolling with the mouse just naturally doesn't work after this code, so we have prevented the scrolling.
