Question

我正在使用 Packery 一个JavaScript库和jQuery插件，它可以创建由David DeSandro创建的无间隙和可拖动布局。我使用它来设置我的投资组合，但下面的代码不起作用。我想使元素可拖动（ draggable ）并在项目元素之间添加水平和垂直空间（ gutter ）。

Answer 1

始终在顶部包含 jquery.min.js 。主要错误是由于该文件在最后加载而导致未被定义的未定义的类型错误。休息所有代码都是正确的。

这是正确的工作解决方案。

var $grid = $('.grid').packery({
  itemSelector: '.grid-item',
  columnWidth: 100,
  gutter: 10
});

// make all grid-items draggable
$grid.find('.grid-item').each(function(i, gridItem) {
  var draggie = new Draggabilly(gridItem); // bind drag events to Packery

  $grid.packery('bindDraggabillyEvents', draggie);
});

$grid.on('click', '.grid-item', function(event) {
  // change size of item by toggling large class
  $(event.currentTarget).toggleClass('grid-item--large');
  // trigger layout after item size changes
  $grid.packery('layout');
});
