flagstone.js是一款强大的自适应可拖拽排序的瀑布流插件

flagstone.js是一款强大的自适应可拖拽排序的瀑布流插件，兼容手机端，元素可以进行自由的拖拽排序，并伴随有排序动画效果。

使用方式：

第一步引入<script type="text/javascript" src="//repo.bfw.wiki/bfwrepo/js/flagstone-4.0.0.min.js"></script>

第二步配置参数

const fs = flagstone(document.getElementsByTagName('article')[0], {
  //bedPadding: 10, // The padding around the area edge
  //stonesMargin: 10, // Margin between stones in pixels (as an int)
  margin: 10, //间距
  minWidth: 280, // 最小宽度像素
  maxColumns: 5, // 最大列数
  flow: true, //当浏览器视窗改变重新排列动画是否开启
  direction: 'left', // 显示方向，默认从左边开始，也可以选择right从右边开始
  assignReverseZIndexes: false,
  random: false, // 是否随机显示
  square: false, // Makes each flagstone square; default is false
  space: false, // Spaces out stones randomly (as a boolean)
  spaceFrequency: 0.4, // Adjusts the frequency of the amount of spaces (as a float 0.0 - 1.0); default is 0.4
  animationDuration: 1000, // 动画时间秒
  animationTimingFunction: 'ease', // 过渡动画缓冲
  heightAnimationDuration: 2500,
  heightAnimationTimingFunction: 'ease',
  resizeDelay: 250, // 重新排列延迟毫秒
  dragAndDrop: true,
  dragAndDropAutoDelay: 1000,
  dropCallback: function (dragElem, targetElem) {
    // console.log(dragElem);
    // console.log(targetElem);
    return true;
  },
  eventResetDelay: 250,
  eventResizeHeightDuration: 250,
  callback: function (elem, index) {// 大小重新绘制resize事件监听函数
    if (index === 3) {
      elem.classList.add('highlight');
    } else {
      elem.classList.remove('highlight');
    }
  }, // Callback function for each element with index and element arguments
  watch: true,
  watchAll: true,
  watchImages: true });
