先来 看看具体效果：
实现方法：
1.下载并引入 angularjs
2.HTML代码：
<!DOCTYPE html> <html lang="en" ng-app="test"> <head> <meta charset="UTF-8"> <title>Html5 拖拽行为和AngularJs的结合</title> <meta charset="utf-8"/> <script type="text/javascript" src="https://www.jb51.net/js/angular.js"></script> <style> .to-drag, .drag-stop { display: inline-block; } </style> </head> <body ng-controller="main"> <div> <ul> <li ng-repeat="item in list.data" ng-include="'./lefttree.html'"></li> </ul> </div> <div> <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: '停止拖动', child: [{ id: '1-1', name: '1-1_name-右' }, { id: '1-2', name: '1-2_name-右' }] }], drop: function (event, item) { event.preventDefault(); console.log("被拖动的元素:->", $scope.clientInfo); console.log("当前节点:->", item); //调用后端添加接口，实现真实的添加。 }, dragover: function (event) { event.preventDefault(); } } }]); var convertFirstUpperCase = function (str) { return str.replace(/(\w)/, function (s) { return s.toUpperCase(); }); }; rubyDragEventDirectives = {}; angular.forEach("dragstart drag dragenter dragover drop dragleave dragend".split(' '), function (eventName) { var rubyEventName = 'ruby' + convertFirstUpperCase(eventName); rubyDragEventDirectives[rubyEventName] = ['$parse', function ($parse) { //$parse 语句解析器 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>
希望可以对大家有所帮助哦。好久都没写博客啦，嘻嘻最近变懒了，而且特别懒，哈哈哈哈，天热啦，大家多喝水哦，注意防暑。
