This comment is a result of the *element* transclusion performed by `ngRepeat`. Looks like it&#39;s [been happening](https://github.com/angular/angular.js/commit/78656fe0dfc99c341ce02d71e7006e9c05b1fe3f) nearly since the dawn of time (in angular terms) and will be created whenever a directive asks for element transclusion.

While you certainly could wipe it out with direct HTML manipulation, it&#39;s not a safe thing to do. Having read through the source, it suggests this comment is needed to continue compiling your HTML once the original `ngRepeat` element is removed. Additionally, in v1.2.0, `ngRepeat` [adds more comments](https://github.com/angular/angular.js/commit/9efa46ae640cde17487c341daa9a75c0bd79da02) that are used to determine where repeated elements are placed.

To summarise:

* Angular doesn&#39;t let you remove this
* You could do it manually but you would most likely break angular
* &lt;s&gt;To reiterate the comments, it seems a strange request to remove this comment in the first place&lt;/s&gt; - depending on your reasoning for doing this there may be better options for what you want to achieve.

Run this in your dev console to nuke the comments:

    $(&quot;*&quot;).contents().filter(function(){ return this.nodeType == 8;}).remove();

Not a proper fix, but handy snippet while debugging.

    $compileProvider.debugInfoEnabled(false);
But it can broke some plugins which have references on angular comments.

I am having trouble getting LibCurl to work with Visual Studio 2013. I downloaded the current version (curl-7.33.0) and tried following the instructions I found on this site: [Using LibCurl with Visual 2010][1]

But I can&#39;t find **curllib.lib** in the folder I downloaded. And I am still getting errors:
![enter image description here][2]


After searching the internet for more help. I now get these error messages. There appears to be a problem with linking to libcurl.lib? 

![enter image description here][3]


This is what I have configured:
![enter image description here][4]

______
![enter image description here][5]

Inside /lib I have **libcurl.lib** and **libcurl.dll**

-------

**UPDATE**

I downloaded this release for Win32 MSVC: http://curl.haxx.se/download.html#Win32
After adding the libcurl libraries and successfully compiling, I am now getting this error message:

  

     The application was unable to start correctly (0xc000007b). Click OK to close the application.

 
Here is the sample code I am trying to run:

    #include &lt;iostream&gt;
    #include &lt;stdio.h&gt; 
    #include &lt;curl/curl.h&gt; 
    
    
    int main(void)
    {
    	CURL *curl;
    	CURLcode res;
    
    	curl = curl_easy_init();
    	if (curl) {
    		curl_easy_setopt(curl, CURLOPT_URL, &quot;http://google.com&quot;);
    		res = curl_easy_perform(curl);
    
    		/* always cleanup */
    		curl_easy_cleanup(curl);
    	}
    	return 0;
    }

**FINAL UPDATE**

I believe I have gotten LibCurl to work with Visual Studio 2013 now. Persistence ftw! 
Although, after spending hours trying to solve these error messages, I am a little hesitant at saying everything is working fine now. That is why I am putting a bounty on this question to get *clear and concise* instructions on getting LibCurl to work with Visual Studio 2013. 

This is what I did to get it to work:

1. First, download the Win32 MSVC package here: http://curl.haxx.se/download.html#Win32
For these instructions sake, let&#39;s say you downloaded to C:\LibCurl

2. Start a new project in Visual Studio. Go to Project|Project Properties|VC++ Directories|Include Directories| 
Add the path to the include directory inside the downloaded package. (C:\LibCurl\include)

3. Next, go to Project|Project Properties|Linker|General|Additional Library Directories|
Add the path to the lib directory. (Where curllib.dll is located)

4. Then, go to Project|Project Properties|Linker|Input|Additional Dependencies|
And add **curllib.lib**

5. Now if you compile a test program, you will likely get the message saying libsasl.dll is missing. You will need to download this file and put it in the same directory as your build. 
I used 7-Zip to extract **libsasl.dll** from **OpenLDAP for Windows**. [OpenLDAP for Windows][6]


This is the result of my test code from above:

Getting LibCurl to work with Visual Studio 2013

I am using Mailgun API. There is a section that I need to provide a URL to them, then they are going to HTTP Post some data to me.

I provide this URL (http://test.com/MailGun/Webhook.aspx) to Mailgun, so they can Post data. I have a list of parameter names that they are sending like (recipient,domain, ip,...).

I am not sure how get that posted data in my page.
In Webhook.aspx page I tried some code as follows but all of them are empty.



     lblrecipient.text= Request.Form[&quot;recipient&quot;];
  
     lblip.Text= Request.Params[&quot;ip&quot;];

     lbldomain.Text = Request.QueryString[&quot;domain&quot;];

Not sure what to try to get the posted data?

Does anyone knows if you can remove the angular comments that are left in html code?

For example: If I use ngRepeat and there are no items to repeat over, AngularJS leaves this :

    &lt;!-- ngRepeat: post in posts --&gt;

AngularJS leaves comments in HTML: is it possible to remove them?

Does anyone knows if you can remove the angular comments that are left in html code?
For example: If I use ngRepeat and there are no items to repeat over, AngularJS leaves this :
<pre><code class="hljs language-php-template">&#x3C;!-- ngRepeat: post in posts -->
</code></pre>

I have a basic controller that displays my products,

    App.controller(&#39;ProductCtrl&#39;,function($scope,$productFactory){
         $productFactory.get().success(function(data){
               $scope.products = data;
         });
    });

In my view I&#39;m displaying this products in a list

    &lt;ul&gt;
        &lt;li ng-repeat=&quot;product as products&quot;&gt;
            {{product.name}}
        &lt;/li&gt;
    &lt;/ul


What I&#39;m trying to do is when someone click on the product name, i have another view named cart where this product is added.

     &lt;ul class=&quot;cart&quot;&gt;
          &lt;li&gt;
              //click one added here
          &lt;/li&gt;
          &lt;li&gt;
              //click two added here
          &lt;/li&gt;
     &lt;/ul&gt;


So my doubt here is, how do pass this clicked products from first controller to second? i assumed that cart should be a controller too.

I handle click event using directive. Also i feel i should be using service to achieve above functionality just can&#39;t figure how? because cart will be predefined number of products added could be 5/10 depending on which page user is. So i would like to keep this generic.


Update: 
 
I created a service to broadcast and in the second controller i receive it. Now the query is how do i update dom? Since my list to drop product is pretty hardcoded.




Passing data between controllers in Angular JS?

I know there are many questions ask similar thing. But no one really solve my issue.

I&#39;m trying to build an directive which will execute an expression when mouse click outside the current element.

Why I need this function? I&#39;m building an app, in this app, there are 3 dropdown menu, 5 dropdown list(like chosen). All these are angular directives. Let&#39;s assume all these directives are different. So we have 8 directives. And all of them need a same function: when click out side the element, need hide the dropdown.

I have 2 solutions for this, but both got issue:

Solution A:

    app.directive(&#39;clickAnywhereButHere&#39;, function($document){
      return {
        restrict: &#39;A&#39;,
        link: function(scope, elem, attr, ctrl) {
          elem.bind(&#39;click&#39;, function(e) {
            // this part keeps it from firing the click on the document.
            e.stopPropagation();
          });
          $document.bind(&#39;click&#39;, function() {
            // magic here.
            scope.$apply(attr.clickAnywhereButHere);
          })
        }
      }
    })

Here is an example for solution A: [click here][1] 

When you click the first dropdown, then working, then click second input, the first should hide but not.


Solution B:

    app.directive(&#39;clickAnywhereButHere&#39;, [&#39;$document&#39;, function ($document) {
        directiveDefinitionObject = {
            link: {
                pre: function (scope, element, attrs, controller) { },
                post: function (scope, element, attrs, controller) {
                    onClick = function (event) {
                        var isChild = element.has(event.target).length &gt; 0;
                        var isSelf = element[0] == event.target;
                        var isInside = isChild || isSelf;
                        if (!isInside) {
                            scope.$apply(attrs.clickAnywhereButHere)
                        }
                    }
                    $document.click(onClick)
                }
            }
        }
        return directiveDefinitionObject
    }]);

Here is example for solution B: [click here][2]

Solution A working if there is just one directive in the page but not in my app. Because it&#39;s prevent bubbling, so first when I click on dropdown1, show dropdown1, then click on dropdown2, click event be prevent, so dropdown1 still showing there even I click outside the dropdown1.

Solution B working in my app which I&#39;m using now. But the issue is it&#39;s cause a performance issue. Too many click event be handled on every single click on anywhere in the app. In my current case, there are 8 click event bind with document, so every click execute 8 functions. Which cause my app very slow, especially in IE8.


So is there any better solution for this? Thanks

Directive that fires an event when clicking outside of the element

I am writing tests in Protractor for an Angular app. I want to fill out a login form and submit it. 

How can I do this? I have got this far, but I don&#39;t know how to set the value of the email and password fields. 

    describe(&#39;The dashboard&#39;, function() {
      ptor = protractor.getInstance();
    
      beforeEach(function() {
        ptor.get(&#39;#/dashboard&#39;);
        var email = ptor.findElement(protractor.By.model(&#39;email&#39;));
        var password = ptor.findElement(protractor.By.model(&#39;password&#39;));
        var submit = ptor.findElement(protractor.By.tagName(&#39;button&#39;));
        // Fill out the form?
        submit.click();
      });
    
      it(&#39;has a heading&#39;, function() {
        heading = ptor.findElement(protractor.By.tagName(&#39;h1&#39;));
        expect(heading.getText()).toEqual(&#39;My Dashboard&#39;);
      });
    });

Protractor testing: How to set the value of text elements in a login form?

**What I&#39;m trying to achieve**

I would like to to transition to a certain state (login) in case an $http request returns a 401 error. I have therefore created an $http interceptor.

**The problem**

When I am trying to insert &#39;$state&#39; into the interceptor I get a circular dependency. Why and how do i fix it?

**Code**

    //Inside Config function

		var interceptor = [&#39;$location&#39;, &#39;$q&#39;, &#39;$state&#39;, function($location, $q, $state) {
			function success(response) {
				return response;
			}

			function error(response) {

				if(response.status === 401) {
					$state.transitionTo(&#39;public.login&#39;);
					return $q.reject(response);
				}
				else {
					return $q.reject(response);
				}
			}

			return function(promise) {
				return promise.then(success, error);
			}
		}];

		$httpProvider.responseInterceptors.push(interceptor);

Injecting $state (ui-router) into $http interceptor causes circular dependency

I&#39;m trying out Protractor to e2e test Angular app and haven&#39;t figured out how to detect if an element has a specific class or not.

In my case, the test clicks on submit button and now I want to know if form[name=&quot;getoffer&quot;] has class .ngDirty. What may be the solutions?

    describe(&#39;Contact form&#39;, function() {
        beforeEach(function(){
            browser.get(&#39;http://localhost:9000&#39;);
            element(by.linkText(&#39;Contact me&#39;)).click();
        });

        it(&#39;should fail form validation, all fields pristine&#39;, function() {
            element(by.css(&#39;.form[name=&quot;getoffer&quot;] input[type=&quot;submit&quot;]&#39;)).click();
            expect(element(by.name(&#39;getoffer&#39;))).toHaveClass(&#39;ngDirty&#39;); // &lt;-- This line
        });
    });

How to test if an element has class using Protractor?

I want to create a directive that checks if an element should be present in the dom based on a value coming from a service (e.g. check for a user role).

The corresponding directive looks like this:

    angular.module(&#39;app&#39;, []).directive(&#39;addCondition&#39;, function($rootScope) {
        return {
            restrict: &#39;A&#39;,
            compile: function (element, attr) {
              var ngIf = attr.ngIf,
                  value = $rootScope.$eval(attr.addCondition);
    
              /**
               * Make sure to combine with existing ngIf!
               * I want to modify the expression to be evalued by ngIf here based on a role 
               * check for example
               */
              if (ngIf) {
                value += &#39; &amp;&amp; &#39; + ngIf;
              }
    
              attr.$set(&#39;ng-if&#39;, value);
            }
        };
    });

At the end the element has the ng-if attribute attached but somehow it doesn&#39;t apply to the element and it is still existing in the dom. So this is obviously a wrong approach. 

This fiddle shows the problem: http://jsfiddle.net/L37tZ/2/

Who can explain why this happens? Is there any other way a similar behaviour could be achieved? Existing ngIfs should be considered.

# SOLUTION:

Usage: `&lt;div rln-require-roles=&quot;[&#39;ADMIN&#39;, &#39;USER&#39;]&quot;&gt;I&#39;m hidden when theses role requirements are not satifisfied!&lt;/div&gt;`

    .directive(&#39;rlnRequireRoles&#39;, function ($animate, Session) {

      return {
        transclude: &#39;element&#39;,
        priority: 600,
        terminal: true,
        restrict: &#39;A&#39;,
        link: function ($scope, $element, $attr, ctrl, $transclude) {
          var block, childScope, roles;

          $attr.$observe(&#39;rlnRequireRoles&#39;, function (value) {
            roles = $scope.$eval(value);
            if (Session.hasRoles(roles)) {
              if (!childScope) {
                childScope = $scope.$new();
                $transclude(childScope, function (clone) {
                  block = {
                    startNode: clone[0],
                    endNode: clone[clone.length++] = document.createComment(&#39; end rlnRequireRoles: &#39; + $attr.rlnRequireRoles + &#39; &#39;)
                  };
                  $animate.enter(clone, $element.parent(), $element);
                });
              }
            } else {

              if (childScope) {
                childScope.$destroy();
                childScope = null;
              }

              if (block) {
                $animate.leave(getBlockElements(block));
                block = null;
              }
            }
          });
        }
      };
    });

It is very important to add the priority in the directive, otherwise other directives attached to that element are not evaluated!

AngularJS: What&#39;s the best practice to add ngIf to a directive programmatically?

I&#39;ve read several articles and StackOverflow questions relating to the setting of focus in AngularJs.

Unfortunately all the examples that I have read assume that there is some attribute that I can add to the element to gain focus, e.g. a [focusMe directive][1].

However what if I don&#39;t know in advance which input to set focus to? In particular how do I set focus to the first input element in a form that has $invalid set - i.e. an element that fails validation.  There could be several inputs that fail validation, so I cannot use a directive that just tries to call .focus() based on this.  (I am doing this for Accessibility/WCAG reasons, its good practice to do so on submit being clicked to minimize keypresses to find the first field that has failed validation).

The $error object will give all controls that fail validation, but they are grouped by the type of failure not in any order of appearance on the form.

I&#39;m sure I can come up with some kludged way of doing this. A directive on the form, which receives some broadcast when focus needs to be set - that directive can then search for the first $invalid element.  However this seems very complex and I&#39;d like to know whether these is a better more &#39;angular&#39; way of doing this.

Set focus on first invalid input in AngularJs form

Does the question mark after equals have special meaning? ie:

    scope: {foo: &#39;=?&#39;}

does the above mean &#39;do not raise error if &#39;foo&#39; cannot be resolved?

what&#39;s the meaning of &#39;=?&#39; in angularJS directive isolate scope declaration?

I have an angular directive which is initialized like so:

    &lt;conversation style=&quot;height:300px&quot; type=&quot;convo&quot; type-id=&quot;{{some_prop}}&quot;&gt;&lt;/conversation&gt;

I&#39;d like it to be smart enough to refresh the directive when `$scope.some_prop` changes, as that implies it should show completely different content.

I have tested it as it is and nothing happens, the linking function doesn&#39;t even get called when `$scope.some_prop` changes. Is there a way to make this happen ?

Angular Directive refresh on parameter change

This directive is trying to create an HTML element called progress bar that tracks progress as you move page to page. I&#39;m trying to develop it to be used as : 
    `&lt;progress-bar progress=&#39;1&#39; max=&#39;6&#39; error=&quot;true&quot;&gt;&lt;/progress-bar&gt;`

I&#39;m simply trying to pass the information from the ^^element in html to my directive and process the information to change the progress bar appropriately.

This is working for &quot;progress&quot; and &quot;max&quot; which take integer values, but for some reason the commented out code, which would process &quot;error&quot; (which is a string) is causing problems. I&#39;m new to angularJS so I&#39;m sorry if any of this sounds confusing or unclear... please ask if I need to elaborate/clarify. Thanks in advance!
