Menu
I'm using a template to create a popup menu that will show alerts if there is a new one and it's working till now. But i wanted to add manual alert, that's why i thought to add an input text but Oupss, i can't write on the input field and i don't even know why.The input field is sort of Disabled!!!
My directive is like so :
$scope.tb = { x: 0, y: 0 };
module.directive('myDraggable', function ($document, $interval) {
return {
restrict: 'EA',
replace: true,
//scope : true,
scope: { menu: '=drSrc'},
link: function (scope, element, attr) {
var startX = 0, startY = 0, x = scope.menu.x || 0, y = scope.menu.y || 0, positionX = [], positionY = [], time = [], width, height, moveInterval;
element.draggable({
position: 'relative',
cursor: 'pointer',
top: y + 'px',
left: x + 'px'
});
element.on('mousedown', function (event) {
// Prevent default dragging of selected content
event.preventDefault();
startX = event.pageX - x;
startY = event.pageY - y;
$document.on('mousemove', mousemove);
$document.on('mouseup', mouseup);
$interval.cancel(moveInterval);
});
function mousemove(event) {
y = event.pageY - startY;
x = event.pageX - startX;
//calculate the borders of the document
width = $(document).width() - 350;
height = $(document).height() - 150;
positionX.push(x);
positionY.push(y);
time.push(Date.now());
}
}
}
});
I tried to make scope true but i faced 2 problems, : I can't move my popup anymore (yes my popup menu is Draggable) And Also the input text does not show my text i'm typing.
Here's my cache template :
$templateCache.put('control.tpl.html', '<div class="container" my-draggable dr-src="tb"><div><div class="col-sm-1 col-md-1 sidebar"><div class="list-group" ><span href="#" class="list-group-item active" >Manage<input type="text" class="pull-right" placeholder="Type..." /></span><div ng-repeat="Alert in Alerts"><a href="#" ng-click="showLocation(Alert.id)" class="list-group-item" >Alert {{Alert.id}}</span><img src="../images/alert_icon_manage.png" class="pull-right"/> </a></div><span href="#" class="list-group-item active"></span></div></div></div></div>');
I'm new with AngularJS and Directive and I don't know how to solve this but I think it's a problem with Scopes!! Thank you.
UPDATE :
If I delete scope:{menu:"=drSrc"} That work and i can type what i want but the problem is that my element is no more draggable. I think it's sth related to scopes. can anyone help please?

It is tempting to do too much work in the AngularJS controller. After all, the controller is where the view first has access to JavaScript via $scope functions. However, doing this will cause you to miss out on code sharing across the site and is not recommended by AngularJS documentation.
Restrict. Angular allows us to set a property named restrict on the object we return on our directive definition. We can pass through a string with certain letters letting Angular know how our directive can be used. function MyDirective() { return { restrict: 'E', template: '<div>Hello world!
ng-state is not an AngularJS directive. Q 15 - Which of the following is true about ng-app directive? A - ng-app directive defines and links an AngularJS application to HTML.
AngularJS directives are extended HTML attributes with the prefix ng- . The ng-app directive initializes an AngularJS application. The ng-init directive initializes application data. The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.
scope: true indicates that your directive should inherit its parent's scope, but scope: {menu: '=drSrc'} creates an isolated scope, which remove your template's access to Alerts. When you remove scope: {menu: '=drSrc'}, menu no longer exists, so scope.menu.x fails and your element is no longer draggable.
The simplest fix is to use scope: true and reference scope.drSrc.x, etc. instead of scope.menu.x. With scope: true, you get access to the parent's scope, including drSrc and the Alerts data your template is using.
These writeups are useful in understanding directives and scopes:

I'm currently working on a project that depends heavily upon Modal Dialogs. Each with their own purpose and dynamic content.
Here's the system I have been working with:
index.html
<!doctype html>
<html ng-app="myApp" ng-controller="MainCtrl">
<head>
<title>Dialogs</title>
<link rel="stylesheet" href="app.css">
</head>
<body>
<button ng-click="openDialog()">Open Dialog</button>
<modal-dialog show="showMe" dialog-controller="WelcomeDialogCtrl" context="welcome"></modal-dialog>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.js"></script>
<script src="app.js"></script>
</body>
</html>
app.js
var app = angular.module('myApp', []);
// The main controller, which will handle index.html
app.controller('MainCtrl', ['$scope', function($scope) {
$scope.showMe = false;
$scope.openDialog = function(){
$scope.showMe = true; // Show the 'welcome' dialog
};
}]);
// The modal dialog directive
app.directive('modalDialog', [function() {
return {
controller: '@', // Bind a controller
name: 'dialogController', // Bind the controller to this attribute name
restrict: 'E',
scope: {
show: '='
},
link: function(scope, element, attrs) {
// Close this dialog (actually ng-hides it)
scope.closeDialog = function() {
scope.show = false;
};
},
templateUrl: function(element, attrs){
// I prefer to load my dialog templates from a separate folder to keep my project tidy
return 'dialogs/' + attrs.context + '.html';
}
};
}]);
// The 'welcome' dialog has its own controller with its own scope
app.controller('WelcomeDialogCtrl', ['$scope', function($scope){
// This can be called by the template that resides within the directive
$scope.exampleFunction = function(text){
console.log('Example function says: ' + text);
};
}]);
welcome.html
<div class="dialog" ng-show="show">
<div class="dialog-overlay"></div>
<div class="dialog-box">
Welcome, be sure to check out this blazin' dialog.
<button ng-click="exampleFunction('Hi!')">Say Hi!</button>
<button ng-click="closeDialog()">Close</button>
</div>
</div>
app.css
body{
background: #eee;
margin: 80px;
}
/*
* Just some fancy schmuck
*/
button{
border-radius: 5px;
background: #272;
color: #fff;
padding: 5px 12px;
border: 0;
}
/*
* The grey, transparent curtain.
*/
.dialog-overlay {
width: 100%;
height: 100%;
position: absolute;
background: #111;
opacity: 0.2;
top: 0;
left: 0;
z-index: 100;
}
/*
* The dialog itself. Horribly centered.
*/
.dialog-box{
background: #fff;
border-radius: 5px;
padding: 10px 20px;
position: absolute;
width: 600px;
height: 300px;
top: 50%;
left: 50%;
margin-left: -300px;
z-index: 110;
}
I also made a Plunker with the same code.
