Illegal use of ngTransclude directive in the template when using compile in directive controller

I'm using compile in my directive controller to get the first directive element and compile it and then use it for other purpose I don't want to use the linking method of my directive, is there anyway to get rid this error ?
I've reproduced the issue in this JSFIDDLE:
var app = angular.module('app', []);
app.directive('panel', function ($compile) {
return {
restrict: "E",
replace: true,
transclude: true,
template: "<div><h1>handrouss</h1><div ng-transclude ></div></div>",
controller: function($scope, $element) {
var el = $compile($element.find('div')[0])($scope); // <--- this causing the issue
$scope.handrouss = el.html();
},
link: function (scope, elem, attrs) {
}
}
});
app.directive('panel1', function ($compile) {
return {
restrict: "E",
replace:true,
transclude: true,
template:"<div ng-transclude></div>",
link: function (scope, elem, attrs) {
elem.children().wrap("<div>");
}
}
});
HTML :
<div data-ng-app="app">
<panel1>
<panel>
<input type="text" ng-model="firstName" />{{firstName}}
</panel>
<input type="text" ng-model="lastname" />
</panel

Remove the ng-transclude attribute from the element before compiling in the controller.
app.directive('panel', function ($compile) {
return {
restrict: "E",
replace: true,
transclude: true,
template: "<div><h1>handrouss</h1><div ng-transclude ></div></div>",
controller: function($scope, $element) {
var div = $element.find('div');
//REMOVE ng-transclude attribute
div.removeAttr('ng-transclude');
var el = $compile(div[0])($scope);
$scope.handrouss = el.html();
},
link: function (scope, elem, attrs) {
}
}
});
As the transclusion has already been done in the compile phase of the directive the ng-transclude directive is no longer needed when compiling in the controller.

How to append element in post function of compile - AngularJS

So, this is my problem. I have two directives (say parent directive and child directive) and i am calling child directive from parent directive like this :
angular.module('components', [])
.directive('helloWorld', function() {
return {
restrict: 'E',
compile: function(element, attrs) {
var x = '<directive2></directive2>';
element.append(x);
}
}
})
.directive("directive2", function($compile, $parse) {
return {
restrict: 'E',
compile: function(iElement, iAttrs, transclude) {
iElement.append('<p>directive2</p>');
}
}
});
angular.module('HelloApp', ['components'])
This works fine. But now i am writing a condition in post function of compile and when that condition satisfy, the child directive should append.
I just added the append function inside the post function, but its not working.
angular.module('components', [])
.directive('helloWorld', function() {
return {
restrict: 'E',
compile: function(element, attrs) {
return {
post: function(scope, element, attrs) {
var x = '<directive2></directive2>';
element.append(x);
}
}
}
}
})
.directive("directive2", function($compile, $parse) {
return {
restrict: 'E',
compile: function(iElement, iAttrs, transclude) {
iElement.append('<p>directive2</p>');
}
}
});
angular.module('HelloApp', ['components'])
I dont know what went wrong. Guide me friends
jsFiddle

You need to use the $compile service before appending as below:
angular.module('components', [])
.directive('helloWorld', function($compile){
return {
restrict: 'E',
link: function(scope, element, attrs) {
var x = angular.element('<directive2></directive2>');
element.append($compile(x)(scope));
}
}
})
.directive("directive2", function() {
return {
restrict: 'E',
compile: function(element, attrs, transclude) {
element.append('<p>directive2</p>');
}
}
});
angular.module('HelloApp', ['components']);
http://jsfiddle.net/2zbabkjb/2/

Try to define template to your first directive :
angular.module('components', [])
.directive('helloWorld', function() {
return {
restrict: 'E',
template: '<directive2></directive2>'
}
}
})

ng-bind-html and ng-controller

I'm injecting insecure html into some <div>, like this:
<div class="category-wrapper" ng-bind-html="content"></div>
this html has angularjs "code" ($scope.content is loaded with something like this):
<script type='text/javascript' src='giveus.js'></script>
<div class="giveus-wrapper" ng-controller="GiveUsController">{{variable1}}</div>
Note that this snippet has ng-controller. GiveUsController is lazy loaded at the same time that the embedded html (not in head). There is no error declaring this controller because It has been already tested.
My controller is as easy as:
angular.module("tf").controller('GiveUsController', function ($scope, $http)
{
console.debug("GiveUsController loaded");
$scope.variable1 = "hi!";
}
there is no console debug nor variable1 assignment
It looks like there is no controller binding to that <div>.
I don't know how I can inject html with angular controller and make it work...
Any idea?

You could do what you are wanting with a bit of manual html compilation. Here is an approach that is essentially a directive wrapper for the $compile service. Observe the following example and usage...
<div class="category-wrapper" ng-html="content"></div>
.controller('ctrl', function($scope) {
$scope.content = '<div class="giveus-wrapper" ng-controller="GiveUsController">{{variable1}}</div>'
})
.controller('GiveUsController', function($scope) {
console.log('hello from GiveUsController')
$scope.variable1 = 'I am variable 1'
})
.directive('ngHtml', ['$compile', function ($compile) {
return function (scope, elem, attrs) {
if (attrs.ngHtml) {
elem.html(scope.$eval(attrs.ngHtml));
$compile(elem.contents())(scope);
}
scope.$watch(attrs.ngHtml, function (newValue, oldValue) {
if (newValue && newValue !== oldValue) {
elem.html(newValue);
$compile(elem.contents())(scope);
}
});
};
}]);

Angular for itself don't bind the ng-directives that are added into the DOM.
The $sce.compile or $compile helps angular to read which elements are added into the actual DOM, also for use the $compile you must use a directive.
Should be like that:
var m = angular.module(...);
m.directive('directiveName', function factory(injectables) {
return = {
priority: 0,
template: '<div></div>', // or // function(tElement, tAttrs) { ... },
transclude: false,
restrict: 'A',
templateNamespace: 'html',
scope: false,
controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
controllerAs: 'stringIdentifier',
bindToController: false,
require: 'siblingDirectiveName', 'optionalDirectiveName', '?^optionalParent'],
compile: function compile(tElement, tAttrs, transclude) {
return {
pre: function preLink(scope, iElement, iAttrs, controller) { ... },
post: function postLink(scope, iElement, iAttrs, controller) { ... }
}
},
};
});
and where you want
$compileProvider.directive('compile', function($compile) {
return function(scope, element, attrs) {
scope.$watch(
function(scope) {
return scope.$eval(attrs.compile);
},
function(value) {
element.html(value);
$compile(element.contents())(scope);
}
);
};

You have to compile the HTML content, i got this using a directive:
.directive('comunBindHtml', ['$compile', function ($compile) {
return function(scope, element, attrs) {
scope.$watch(
function(scope) {
// watch the 'compile' expression for changes
return scope.$eval(attrs.compile);
},
function(value) {
// when the 'compile' expression changes
// assign it into the current DOM
element.html(value);
// compile the new DOM and link it to the current
// scope.
// NOTE: we only compile .childNodes so that
// we don't get into infinite loop compiling ourselves
$compile(element.contents())(scope);
}
);
};
}])
Hope it helps :)

How to make two way binding between angular directives without using "dots"

Suppose, I have controller:
angular.module('tf').controller('Ctrl', function($scope){
$scope.params = {
orderBy: null
};});
And a directive "common":
angular.module('tf').directive("common", function() {
return {
restrict: 'E',
replace: true,
template: '<div><outer order-by="orderBy"><inner order-by-field="name1"></inner><inner order-by-field="name2"></inner></outer></div>',
controller: function ($scope) {
},
scope: {
orderBy: '='
},
link: function (scope, element, attrs) {
}
}});
Controller is using directive within it's template:
<div ng-app="tf">
<div ng-controller="Ctrl">
<common order-by="params.orderBy"></common>
<div style="color:red">{{params.orderBy}}</div>
</div>
This directive is using directive "outer":
angular.module('tf').directive("outer", function() {
return {
restrict: 'E',
transclude: true,
replace: true,
template: '<div ng-transclude></div>',
controller: function ($scope) {
this.order = function (by) {
$scope.orderBy = by
};
},
scope: {
orderBy: '=',
}
}});
Which is parent for the directive "inner":
angular.module('tf').directive("inner", function() {
return {
require: '^outer',
restrict: 'E',
transclude: true,
replace: true,
template: '<div ng-click="onClicked()">{{orderByField}}</div>',
controller: function ($scope) {
$scope.onClicked = function () {
$scope.outer.order($scope.orderByField);
}
},
scope: {
orderByField: '#'
},
link: function (scope, element, attrs, outer) {
scope.outer = outer;
}
}});
The directive "outer" shares "order" method with directive "inner" by it's controller. The directive "inner" is accessing it by using "require" mechanism.
For some reason, this is not working as expected (Property of the controller isn't updated each time it's changed by directive). If I place "orderBy" into object (e.g. {"order": {"by": null }} ) and use object instead of string value, everything is working as expected ( controller scope is properly updated by the directive). I know about "always use dots" best practices principle, but I don't wanna use it here, because it would make my directive's API less intuitive.

Communicate action thru directive attributes

I'm probably missing something here on the way $observe works inside directive. I have to child directive that needs to communicate thru their parent directive:
<parent>
<button>Change text</button>
<child text="child element"></child>
</parent>
app.directive('button', function() {
return {
require: '^parent',
scope: true,
restrict: 'E',
link: function(scope, element, attrs, parentCtrl) {
element.bind('click', function() {
parentCtrl.changeText();
});
},
};
});
app.directive('parent', function() {
return {
restrict: 'E',
scope: true,
controller: function($scope, $element, $attrs) {
var child = $element.find('child');
this.changeText = function() {
child.attr('text', 'new text');
};
}
};
});
app.directive('child', function() {
return {
restrict: 'E',
scope: true,
link: function(scope, element, attrs) {
attrs.$observe('text', function(text) {
element.html(text);
});
}
};
});
That code is only to illustrate an problem I have in the app i'm developing. All directive needs to have a isolated scope, so I cannot communicate with it. I made a plunker. Feel free to let me know if there's a better way to communicate to the child directive from the parent one.
Thank's a lot, as always!

I didnt understand why the parent and child has to have isolated scope but if you just want to communicate between parent and child you can use $emit and $on.
app.directive('parent', function($rootScope) {
return {
restrict: 'E',
scope: true,
controller: function($scope, $element, $attrs) {
var child = $element.find('child');
this.changeText = function() {
child.attr('text', 'new text');
};
$rootScope.$emit('FromParent', somedata);
}
};
});
app.directive('child', function($rootScope) {
return {
restrict: 'E',
scope: true,
link: function(scope, element, attrs) {
attrs.$observe('text', function(text) {
element.html(text);
});
$rootScope.$on('FromParent', function(event, somedata){
//Do something with the data
});
}
};
});
