好用的jq拖拽插件

<script src="https://npmcdn.com/draggabilly@2.1/dist/draggabilly.pkgd.min.js"></script><!-- or --><script src="https://npmcdn.com/draggabilly@2.1/dist/draggabilly.pkgd.js"></script>

对于单个ID对应的使用方法：

var elem = document.querySelector('#draggable');var draggie = new Draggabilly( elem, {  // options...});

对于多个ID同一class的使用方法：

var draggableElems = document.querySelectorAll('.draggable');var draggies = []for ( var i=0, len = draggableElems.length; i < len; i++ ) {  var draggableElem = draggableElems[i];  var draggie = new Draggabilly( draggableElem, {    // options...  });  draggies.push( draggie );}
