I want to know how to do drag and drop by using AngularJs.

This is what I have so far:

http://blog.parkji.co.uk/2013/08/11/native-drag-and-drop-in-angularjs.html This is simple method for creating native draggable angularJS elements

Answer 2

Angular doesn't provide snazzy UI elements like drag and drop. That's not really Angular's purpose. However, there are a few well known directives that provide drag and drop. Here are two that I've used.

small scripts for drag and drop by angular

(function(angular) {
  'use strict';
angular.module('drag', []).
  directive('draggable', function($document) {
    return function(scope, element, attr) {
      var startX = 0, startY = 0, x = 0, y = 0;
      element.css({
       position: 'relative',
       border: '1px solid red',
       backgroundColor: 'lightgrey',
       cursor: 'pointer',
       display: 'block',
       width: '65px'
      });
      element.on('mousedown', function(event) {
        // Prevent default dragging of selected content
        event.preventDefault();
        startX = event.screenX - x;
        startY = event.screenY - y;
        $document.on('mousemove', mousemove);
        $document.on('mouseup', mouseup);
      });

      function mousemove(event) {
        y = event.screenY - startY;
        x = event.screenX - startX;
        element.css({
          top: y + 'px',
          left:  x + 'px'
        });
      }

      function mouseup() {
        $document.off('mousemove', mousemove);
        $document.off('mouseup', mouseup);
      }
    };
  });
})(window.angular);

Modified from the angular-drag-and-drop-lists examples page

Markup

<div class="row">
    <div ng-repeat="(listName, list) in models.lists" class="col-md-6">
        <ul dnd-list="list">
            <li ng-repeat="item in list" 
                dnd-draggable="item" 
                dnd-moved="list.splice($index, 1)" 
                dnd-effect-allowed="move" 
                dnd-selected="models.selected = item" 
                ng-class="{'selected': models.selected === item}" 
                draggable="true">{{item.label}}</li>
        </ul>
    </div>
</div>

Angular

var app = angular.module('angular-starter', [
    'ui.router',
    'dndLists'
]);

app.controller('MainCtrl', function($scope){

    $scope.models = {
        selected: null,
        lists: {"A": [], "B": []}
    };

    // Generate initial model
    for (var i = 1; i <= 3; ++i) {
        $scope.models.lists.A.push({label: "Item A" + i});
        $scope.models.lists.B.push({label: "Item B" + i});
    }

    // Model to JSON for demo purpose
    $scope.$watch('models', function(model) {
        $scope.modelAsJson = angular.toJson(model, true);
    }, true);
});

Library can be installed via bower or npm: angular-drag-and-drop-lists

Using HTML 5 Drag and Drop
You can easily archive this using HTML 5 drag and drop feature along with angular directives.

1. Enable drag by setting draggable = true.
2. Add directives for parent container and child items.
3. Override drag and drop functions - 'ondragstart' for parent and 'ondrop' for child.

Find the example below in which list is array of items.
HTML code:

    <div class="item_content" ng-repeat="item in list" draggrble-container>
        <div class="item" draggable-item draggable="true">{{item}}</div>
    </div>

Javascript:

    module.directive("draggableItem",function(){
     return {
      link:function(scope,elem,attr){
        elem[0].ondragstart = function(event){
            scope.$parent.selectedItem = scope.item;
        };
      }
     };
    });


    module.directive("draggrbleContainer",function(){
     return {
        link:function(scope,elem,attr){
            elem[0].ondrop = function(event){
                event.preventDefault();
                let selectedIndex = scope.list.indexOf(scope.$parent.selectedItem);
                let newPosition = scope.list.indexOf(scope.item);
                scope.$parent.list.splice(selectedIndex,1);
                scope.$parent.list.splice(newPosition,0,scope.$parent.selectedItem);
                scope.$apply();
            };
            elem[0].ondragover = function(event){
                event.preventDefault();

            };
        }
     };
    });

adapt-strap has very light weight module for this. here is the fiddle. Here are some attributes that are supported. There are more.

ad-drag="true"
ad-drag-data="car"
ad-drag-begin="onDragStart($data, $dragElement, $event);"
ad-drag-end="onDataEnd($data, $dragElement, $event);"
