先來(lái) 看看具體效果：

實(shí)現(xiàn)方法：

1.下載并引入 angularjs

2.HTML代碼：

<!DOCTYPE html>
<html lang="en" ng-app="test">
<head>
 <meta charset="UTF-8">
 <title>Html5 拖拽行為和AngularJs的結(jié)合</title>
 <meta charset="utf-8"/>
 <script type="text/javascript" src="js/angular.js"></script>
 <style>
 .to-drag, .drag-stop {
 display: inline-block;
 }
 </style>
</head>
<body ng-controller="main">
<div class="to-drag">
 <ul>
 <li ng-repeat="item in list.data" ng-include="'./lefttree.html'"></li>
 </ul>
</div>
<div class="drag-stop">
 <ul>
 <li ng-repeat="item in rightList.data" ng-include="'./righttree.html'"></li>
 </ul>
</div>
</body>
</html>

3.js

<script type="text/javascript">
 let mod = angular.module("test", []);
 mod.controller("main", ['$scope', function ($scope) {
 $scope.list = {
 data: [{
 id: 1,
 name: '22',
 child: [{
 id: '1-1',
 name: '1-1_name-左'
 }, {
 id: '1-2',
 name: '1-2_name-左'
 }]
 }],
 dragstart: function (item) {
 $scope.clientInfo = item;
 }
 }
 $scope.rightList = {
 data: [{
 id: 1,
 name: '停止拖動(dòng)',
 child: [{

 name: '1-1_name-右'
 }, {

 }]
 }],
 drop: function (event, item) {
 event.preventDefault();
 console.log("被拖動(dòng)的元素:->", $scope.clientInfo);
 console.log("當(dāng)前節(jié)點(diǎn):->", item);
 //調(diào)用后端添加接口，實(shí)現(xiàn)真實(shí)的添加。
 },
 dragover: function (event) {
 event.preventDefault();
 }
 }
 }]);
 var convertFirstUpperCase = function (str) {
 return str.replace(/(\w)/, function (s) {
 return s.toUpperCase();
 });
 };
 rubyDragEventDirectives = {};
 angular.forEach("dragstart drag dragenter dragover drop dragleave dragend".split(' '), function (eventName) {
 var rubyEventName = 'ruby' + convertFirstUpperCase(eventName);
 rubyDragEventDirectives[rubyEventName] = ['$parse', function ($parse) {
 //$parse 語(yǔ)句解析器
 return {
 restrict: 'A',
 compile: function (ele, attr) {
 var fn = $parse(attr[rubyEventName]);
 return function rubyEventHandler(scope, ele) {
 ele[0].addEventListener(eventName, function (event) {
 if (eventName == 'dragover' || eventName == 'drop') {
 event.preventDefault();
 }
 var callback = function () {
 fn(scope, {event: event});
 };
 callback();
 });
 }
 }
 }
 }]
 });
 mod.directive(rubyDragEventDirectives);
</script>
