I was having a problem getting the simple demo to work found here.
I'm getting the two lists to show up, however I am unable to drag and drop items. The demo is very simple, just an html file, javascript file and css file.
Here's my index.html file:
<!DOCTYPE html>
<html ng-app="demo">
<head lang="en">
<meta charset="utf-8">
<title>Drag & Drop Demo</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0/angular.min.js"></script>
<script src="bower_components/angular-drag-and-drop-lists/angular-drag-and-drop-lists.min.js"></script>
<script src="Scripts/my-app.js"></script>
<link href="Content/my-styling.css" rel="stylesheet" />
</head>
<body class="simpleDemo" ng-controller="SimpleDemoController">
<ul dnd-list="list">
<li ng-repeat="item in models.lists.A"
dnd-draggable="item"
dnd-moved="models.lists.A.splice($index, 1)"
dnd-effect-allowed="move"
dnd-selected="models.selected = item"
ng-class="{'selected': models.selected === item}">
{{item.label}}
</li>
</ul>
<ul dnd-list="list">
<li ng-repeat="item in models.lists.B"
dnd-draggable="item"
dnd-moved="models.lists.B.splice($index, 1)"
dnd-effect-allowed="move"
dnd-selected="models.selected = item"
ng-class="{'selected': models.selected === item}">
{{item.label}}
</li>
</ul>
</body>
</html>
Here's my js file:
angular.module("demo", []).controller("SimpleDemoController", 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) {
$scope.modelAsJson = angular.toJson(model, true);
}, true);
});
And here's my css file:
.simpleDemo ul[dnd-list],
.simpleDemo ul[dnd-list] > li {
position: relative;
}
.simpleDemo ul[dnd-list] {
min-height: 42px;
padding-left: 0px;
}
.simpleDemo ul[dnd-list] .dndDraggingSource {
display: none;
}
.simpleDemo ul[dnd-list] .dndPlaceholder {
display: block;
background-color: #ddd;
min-height: 42px;
}
.simpleDemo ul[dnd-list] li {
background-color: #fff;
border: 1px solid #ddd;
border-top-right-radius: 4px;
border-top-left-radius: 4px;
display: block;
padding: 10px 15px;
margin-bottom: -1px;
}
.simpleDemo ul[dnd-list] li.selected {
background-color: #dff0d8;
color: #3c763d;
}
This code is simply copied and pasted from the simple demo, just slightly modified to show lists A and B. Does anyone know what's wrong?
You're forgetting Dependency Injection just replace
angular.module("demo", [])
with
angular.module("demo", ['dndLists'])
and it should work..
plunk
--Update--
I found some problem with your Markup as well you are referencing list in <ul dnd-list="list>" this will not work as you're referencing an undefined variable, you should be referencing the list you are using in the drag-able. for example for the first list you can change.
<ul dnd-list="list">
to
<ul dnd-list="models.lists.A">
and that should work properly now..
P.S I've updated the plunk
you need the next: (that is the dependency injection)
app.requires.push('dndLists');
you are missing the ng-repeat in your angular it should look like this: (ng-repeat="(listName, list) in models.lists")
<div ng-repeat="(listName, list) in models.lists" class="col-md-6 ng-scope">
<div class="panel panel-info">
<div class="panel-heading">
<h3 class="panel-title ng-binding">List A</h3>
</div>
<div class="panel-body ng-scope">
<ul dnd-list="list" class="ng-scope">
<li ng-repeat="item in list"
dnd-draggable="item"
dnd-moved="list.splice($index, 1)"
dnd-effect-allowed="move"
dnd-selected="models.selected = item"
ng-class="{'selected': models.selected === item}"
dnd-disable-if="list.length < 2"
class="ng-binding ng-scope"
draggable="true">
{{item.label}}
</li>
</ul>
</div>
</div>
</div>
I have problem with swapping the dragged/dropped elements.
DOM / Angular Structure:
angular.module('app', ['ngDragDrop'])
.controller('controller', function($scope) {
$scope.listItems = [
{name: "some name", title: "title"},
{name: "some name2", title: "title2"},
];
$scope.input = {};
$scope.draggableOprions = {
revert: 'invalid'
}
});

<div ng-app="app">
<div ng-controller="controller">
<div class="container">
<ul>
<li data-drag="true"
data-jqyoui-options="draggableOprions"
jqyoui-draggable="{animate:true}"
ng-model="item" ng-repeat="item in listItems track by $index">

</li>
</ul>

data-drop="true"
data-jqyoui-options jqyoui-droppable
ng-model="input">
<input ng-model="input.name">
</div>
</div>
</div>
The problem:
While I drag and drop an list item 1 - the name property of the list item 1 comes to the input model. But no longer is available in list item 1. Actually the list item 1 value goes undefined || null after I drop it in the input. If I now try to drag-n-drop list item 2 item in the input - the values swapping (list item 1 = undefined || null ? and list item 2 = list item 1 value and input model equal to list item 2 value`. So everything shuffle.
What I need:
I need to drag and drop list items in the input, avoiding losing values in list items. Every time i drop list item in the input, I need it's value to bind to the input.
Out of the box
I can change the drag and drop library, or even use source code, but the library is the better choice. I accept almost every good working answer which didn't broke any standards of good code (I mean that I need code which will not broke the other code and has good structure).
I suggest to use ngDraggable, an Angular module with no depency from jQuery or jQuery-ui.
Here below is a working snippet or check my Codepen:
angular.module('app', ['ngDraggable'])
.controller('controller', function($scope) {
$scope.listItems = [{
name: "some name",
title: "title1"
}, {
name: "some name2",
title: "title2"
}, {
name: "some name3",
title: "title3"
}, ];
$scope.droppedObjects = [];
$scope.input = {};
// drag complete over drop area
$scope.onDragComplete = function(data, evt) {
console.log("drag success, data:", data);
var index = $scope.droppedObjects.indexOf(data);
if (index > -1) {
$scope.droppedObjects.splice(index, 1);
}
}
// drop complete over drop area
$scope.onDropComplete = function(data, evt) {
console.log("drop success, data:", data);
var index = $scope.droppedObjects.indexOf(data);
if (index == -1)
$scope.droppedObjects.push(data);
}
// drop complete over input box
$scope.onDropCompleteInput = function(data, evt) {
console.log("drop on input success, data:", data);
$scope.input = data;
}
// drop complete over items area (remove from dropped list)
$scope.onDropCompleteRemove = function(data, evt) {
console.log("drop success - remove, data:", data);
var index = $scope.droppedObjects.indexOf(data);
if (index != -1)
$scope.droppedObjects.splice(index);
}
// other draggable events handlers
var onDraggableEvent = function(evt, data) {
console.log("128", "onDraggableEvent", evt, data);
}
$scope.$on('draggable:start', onDraggableEvent);
//$scope.$on('draggable:move', onDraggableEvent);
$scope.$on('draggable:end', onDraggableEvent);
});

You have to use helper: 'clone' in data-jqyoui-options
In my angular.js learning project I want to hide one div and show another when I click a button.
In this code, I'd like the first div to be hidden at the click (or even destroyed?) and the second div to be shown.
Basically I want the user experience of going from page 1 to page 2 in my app.
How do I make this happen?
Index.html
<ion-content ng-controller="StartpageCtrl">
<div class="list card" id="startCard" ng-show="showstartCard">
<div class="item item-image item item-text-wrap">
Card 1
</div>
</div>
<div class="list card" id="secondCard" ng-show="showsecondCard">
<div class="item item-image item item-text-wrap">
Card 2
</div>
</div>
<button ng-click="hideCard()" class="button button-full button-calm button icon-right ion-chevron-right">
Start now
</button>
</ion-content>
controllers.js
.controller("StartpageCtrl", funcion($scope){
$scope.showstartCard = true;
$scope.showsecondCard = false;
$scope.hideCard = function() {
$scope.showstartCard = false;
$scope.showsecondCard = true;
};
});
When I run the page I see "Card 2" and nothing happens when I click the button.
What I wanted to see was "Card 1" and for it to switch to "Card 2" as I click the button...
Solved
I had forgotten to add references to controllers.js in the app.js angular.module as well as the script tag in index.html. It works fine now.
Using angular:
HTML file:
<td>Source Doc..
<div id="mydiv" ng-show="showDetails">
<div id="mydiv-container">
<div id="mydiv-content">
Close
<br>
hello
</div>
</div>
</div>
</td>
css file:
body {
height: 100%;
background-color: #F0F0F0;
font-family: Arial, sans-serif;
}
#mydiv {
width: 100%;
height: 100%;
overflow: hidden;
left: 100px;
top: 150px;
position: absolute;
opacity: 0.95;
}
#mydiv-container {
margin-left: auto;
margin-right: auto;
}
#mydiv-content {
width: 70%;
padding: 20px;
background-color: white;
border: 1px solid #6089F7;
}
a {
color: #5874BF;
text-decoration: none;
}
a:hover {
color: #112763;
}
If you are looking for toggle, then this code might help as there is no need to have any extra CSS or JS functions needed.
<button ng-click="isDetailOpen = !isDetailOpen"
ng-class="!isDetailOpen ? 'ion-ios-arrow-down' : 'ion-ios-arrow-up'"

I figured it out while working on Angular-Ionic project.
Am creating an image slider with Angularjs using the codes from here
Using AngularJS 1.15, I could get the image to slide in. But when the second image comes in, the first image will disappear instead of sliding out. Can someone help?
NOTE: this does not work on Firefox and IE but works on Chrome.
Here are my codes
HTML
<div ng-controller="slideShowController" class="imageslide" ng-switch='slideshow' ng-animate="'animate'">
<div class="slider-content" ng-switch-when="1">
<img src="asset/building.jpg" width="100%" height="400px"/>
</div>
<div class="slider-content" ng-switch-when="2">
<img src="asset/slide-2.jpg" width="100%" height="400px"/>
</div>
<div class="slider-content" ng-switch-when="3">
<img src="asset/slide-3.jpg" width="100%" height="400px"/>
</div>
<div class="slider-content" ng-switch-when="4">
<img src="asset/slide-4.jpg" width="100%" height="400px"/>
</div>
</div>
Javascript
function slideShowController($scope, $timeout) {
var slidesInSlideshow = 4;
var slidesTimeIntervalInMs = 3000;
$scope.slideshow = 1;
var slideTimer =
$timeout(function interval() {
$scope.slideshow = ($scope.slideshow % slidesInSlideshow) + 1;
slideTimer = $timeout(interval, slidesTimeIntervalInMs);
}, slidesTimeIntervalInMs);
}
CSS
.imageslide{
width:100%;
height:400px;
margin: 0 auto;
margin-bottom: 20px;
}
.imageslide .slider-content {
position: absolute;
width:100%;

}

}
.animate-leave.animate-leave-active {
left:-100%;
}
.animate-enter.animate-enter-active,.animate-leave {

}
The biggest issue I see with your plunker is the lack of an ng-app attribute on the page. After adding that and changing the animate out to use margin-left it works fine:
.animate-leave.animate-leave-active {
margin-left:-100%;
}

Below is the code I have refer from this page and tested. It worked for me now.
I just need to make it dynamic passing image url from Jsp custom tags.
Note :
It is working for me in Chrome and Firefox.
But it did not work for In IE 10.
I could not understand why it wont working in IE 10 can any one tell? Even it does not show any error in console.

If your shopping cart is the only use-case for drag and drop, then you could tackle this by disabling dragging once the object is in the cart. You can do this by binding the draggable class to an expression which checks whether the object is in the cart.
<div ng-class="{draggable: cart.indexOf(object) != -1}"></div>
Here is a basic fiddle to show you what I mean - note, this doesn't include any dragging or dropping, but is just to highlight the class binding, and get you started.
