Packery：启用 Dragability 和 Gutter答案

【问题标题】：Packery: Enable Dragability And GutterPackery：启用 Dragability 和 Gutter
【发布时间】：2017-09-23 11:09:03
【问题描述】：

我正在使用 Packery 一个 JavaScript 库和 jQuery 插件，它可以制作由 David DeSandro 创建的无缝且可拖动的布局。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) 并在项目元素之间添加水平和垂直空间 (gutter)。

【问题讨论】：

哪一部分不起作用..

标签： javascript html css packery

【解决方案1】：

始终在顶部包含 jquery.min.js。主要错误是由于最后加载的文件导致 未定义打包的未捕获类型错误。其余所有代码都正确。

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');
});

【讨论】：

以下代码在位于服务器外部时不起作用。例如，我只是把它放在桌面上它不起作用，但是当放入服务器或本地主机时它工作正常。但是，谢谢:) @Sahil Dhir
仍然无法在服务器外部工作，但在服务器内部工作正常。 @Sahil Dhir
没有显示错误描述。就在我尝试拖动单元格时，什么也没发生。甚至连排水沟都没有启用。当文件位于本地主机或服务器之外时。尝试在桌面上使用上面给定的代码创建一个 .html 文件，然后查看以下输出先生 @Sahil Dhir
