Packery：启用可拖动性和装订线

Question

我正在使用 Packery 一个 JavaScript 库和 jQuery 插件，可以制作由 David DeSandro 创建的无缝和可拖动布局。我用它来设置我的投资组合，但下面的代码不起作用。我想让元素可拖动 (draggable) and adds horizontal and vertical space between item elements (gutter)。

Answer 1

始终在顶部包含 jquery.min.js。主要错误是由于该文件在末尾加载导致 未定义 packery 的未捕获类型错误 。其余所有代码都是正确的。

Here is the correct working solution.

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');
});
