angular实现draggable拖拽

峰澜未语 發表於 2019-11-11 15:38:00

前言：最近项目要实现一个拖拽功能，我在网上开始了各类搜寻，虽然后面因为数据原因舍弃了拖拽的这一需求，但是为了不辜负最近的研究，还是来记录一下。
场景需求：面试预约选时间节点，候选人之间是可以相互交换的，但是局限于面试方向相同的候选人才能相互拖拽（拖拽后即表示两个候选人之间交换面试时间）。本来此种场景上图更为明确，奈何公司只限于内网开发，上传不了图片，嘤嘤嘤。。。
参考文章：https://www.cnblogs.com/starof/p/10662027.html
正文：
draggable是H5新增的属性，true表示可以拖拽,false表示不能拖拽。在拖拽过程中分别有两个元素：被拖动元素与目标元素。
被拖动元素相关的事件：
<ul>
<li>ondragstart：按下鼠标并开始移动时触发该事件。</li>
<li>ondrag：在start事件触发后被触发，并在鼠标移动过程中不停被触发。</li>
<li>ondragend：当拖动停止触发（无论把元素放到拖放目标上还是在无效目标上）</li>
</ul>
目标元素相关的事件：
<ul>
<li>ondragenter：被拖动元素进入目标时触发。</li>
<li>ondragover：被拖动元素在目标元素上移动时被触发。</li>
<li>ondragleave：被拖动元素离开目标时触发，即拖到无效目标时。</li>
<li>ondrop：被拖动元素被放置在目标上时被触发。</li>
</ul>
注意：默认情况下目标元素是不允许被放置的，所以不会触发drop事件。这时需要在ondragover中阻止默认行为才能成为被允许放置的目标。
对于angular、vue等依赖组件开发的框架，最好把draggable封装成指令去实现功能。（实施步骤与参考文章无异，直接上代码啦，其他不赘述）具体步骤：
1.新建directives指令文件夹
2.新建拖拽文件夹directives/drap-drop
3.新建drap指令文件directives/drag-drop/drag.directive.ts
4.新建drop指令文件directives/drag-drop/drop.directive.ts
5.因为涉及数据交换，所以要新建一个services来传递数据，directives/directives.services.ts
6.新建directives/directives.module.ts
7.在公共模板中引入DirectiveModule 
8.引用
