最佳答案

来自documentation :你想为此设置 bounce:false :

var myScroll;

function loaded() {
  myScroll = new IScroll('#wrapper', {
    mouseWheel: true,
    bounce: false
  });
}

document.addEventListener('touchmove', function(e) {
  e.preventDefault();
}, false);
* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}
html {
  -ms-touch-action: none;
}
body,
ul,
li {
  padding: 0;
  margin: 0;

  font-size: 12px;
  font-family: ubuntu, helvetica, arial;
