JQUERY 禁用/恢复手机默认的触屏滚动行为

<script>
//阻止默认
$("body").on("touchmove",function(event){
event.preventDefault;
}, false)

//然后点击取消或者确定时再取消body上的绑定
$("body").off("touchmove");
</script>

上面第一段js阻止了body的滚动,那么如果页面上有一个滚动区域,这个区域在滚动时还是会影响到body的滚动,这个时候,就给这给滚动区域内部再加上同一段js

<div id="about-desc" class="scroll-area"> 
    <div class="scroll-content">
       文本文本文本很高的文本区域
    </div>
</div>
#about-desc {
    height: 550px;
    margin: 0 auto;
    max-width: 560px;
    overflow-y: hidden;
    color: #fff;
    border: 1px solid #fff;
    background: rgba(0,0,0,0.3);
}
#about-desc .scroll-content {
    padding: 30px 10px 30px 20px;
}
$("body").on("touchmove",function(event){
    event.preventDefault;
}, false);
$(".scroll-content").on("touchmove",function(event){
    event.preventDefault;
}, false);

以上js往往会把页面原生的scroll效果也一同去掉了;

var overscroll = function(el) {
  el.addEventListener('touchstart', function() {
    var top = el.scrollTop
      , totalScroll = el.scrollHeight
      , currentScroll = top + el.offsetHeight;
    //If we're at the top or the bottom of the containers
    //scroll, push up or down one pixel.
    //
    //this prevents the scroll from "passing through" to
    //the body.
    if(top === 0) {
      el.scrollTop = 1;
    } else if(currentScroll === totalScroll) {
      el.scrollTop = top - 1;
    }
  });
  el.addEventListener('touchmove', function(evt) {
    //if the content is actually scrollable, i.e. the content is long enough
    //that scrolling can occur
    if(el.offsetHeight < el.scrollHeight)
      evt._isScroller = true;
  });
}
overscroll(document.querySelector('.scroll'));
document.body.addEventListener('touchmove', function(evt) {
  //In this case, the default behavior is scrolling the body, which
  //would result in an overflow.  Since we don't want that, we preventDefault.
  if(!evt._isScroller) {
    evt.preventDefault();
  }
});
