问题描述

 < p>< p>< p>< p>< ; div id =containerstyle =overflow-x:scroll; max-width:1000px;> 
< div id =containedstyle =width:3000px;>< / div>
< / div>

< script>
$('#container')。scroll(function(){
var scrollPercentage; //如何获得滚动百分比?
});
< / script>

因此,如果滚动条完全位于左侧,我们希望得到 0 ,如果完全在右边,我们希望获得 100

解决方案

  var scrollPercentage = 100 * this.scrollLeft /(this.scrollWidth-this.clientWidth);

或者,如果您真的必须使用jQuery:

  scrollPercentage = 100 * $(this).scrollLeft()/($('#contained')。width() -  $(this).width ());

How can we calculate the percentage of 'distance' covered by the scrollbar on an element between start and end?

<div id="container" style="overflow-x:scroll; max-width:1000px;">
  <div id="contained" style="width:3000px;"></div>
</div>

<script>
  $('#container').scroll(function(){
    var scrollPercentage; //How to get scroll percentage?
  });
</script>

So, if the scrollbar is completely at the left we want to get 0, and if it's completely at the right we want to get 100.

解决方案

var scrollPercentage = 100 * this.scrollLeft / (this.scrollWidth-this.clientWidth);

Or, if you really must use jQuery:

scrollPercentage = 100 * $(this).scrollLeft() / ($('#contained').width() - $(this).width());
