页面效果如下所示：

代码请看这里,当当当当:

html:

<template><div class='drag-content'><div class='project-content'><div class='select-item' draggable='true' @dragstart='drag($event)' v-for='pjdt in projectdatas'>{{pjdt.name}}</div></div><div class='people-content'><div class='drag-div' v-for='(ppindex,ppdt) in peopledata' @drop='drop($event)' @dragover='allowDrop($event)'><div class='select-project-item'><label class='drag-people-label'>{{ppdt.name}}:</label></div></div></div></div></template><div class='select-item' draggable='true' @dragstart='drag($event)' v-for='pjdt in projectdatas'>{{pjdt.name}}</div>

在这行代码中小颖在绑定dragstart事件时,drag($event)写法和js写法不一样,如果你在vue中绑定事件时要传 'event',你不能像js那种格式去写 ,比如:@dragstart='drag(event)' 这个写的话你在drag方法中获取到的event是 undefined,因为它把 @dragstart='drag(event)' 中的event当成了一个变量,而该变量并没有在data中定义所以就是 undefined.早上小颖就碰到过此坑.所以切记格式是介个酱紫的: @dragstart='drag($event)'

js代码:

<script>let dom = nullexport default {components: {},ready: function() {},methods: {drag:function(event){dom = event.currentTarget},drop:function(event){event.preventDefault();event.target.appendChild(dom);},allowDrop:function(event){event.preventDefault();},},data() {return {projectdatas:[{id:1,name:'葡萄',},{id:2,name:'芒果',},{id:3,name:'木瓜',},{id:4,name:'榴莲',}],peopledata:[{id:1,name:'小颖',},{id:2,name:'hover',},{id:3,name:'空巢青年三 ',},{id:3,name:'一丢丢',}]}}}</script>
