I have this code bellow and is working well, I would like to know how can make this variable show in my root-scope?
the problem is I am using now different controllers and directives
so:
if I put this in directive1:
Show
<button ng-click="showme=false">Hide</button>
and this in directive2 does not work:
<div class="wrapper">
<p ng-hide="showme">It will appear here!</p>
<h2 ng-show="showme">This is mah content, yo!</h2>
</div>
full code working if in the same directive html + angular
<div ng-app="">
<h1>Ng-show & ng-hide</h1>
<p class="description">Click on the "show"-link to see the content.</p>
Show
<button ng-click="showme=false">Hide</button>
<div class="wrapper">
<p ng-hide="showme">It will appear here!</p>
<h2 ng-show="showme">This is mah content, yo!</h2>
</div>
</div>
I heard about I can use something like: $rootScope but how I can implement this in that case? thank you.
You need to make sure show is set on the $rootScope. Convenient place for this is run block:
.run(['$rootScope', function($rootScope) {
$rootScope.show = false
}])
After that all scopes will inherit show from its parent.
Another option. You can actually directly refer to $rootScope from any of your template, this is probably simplest solution:
Show
<button ng-click="$root.show = false">Hide</button>

I have a controller that basically assigns text to a $scope variable like this;
$scope['Model'] = ["markdown text 1", "markdown text 2"];
And then I try to use marked on it within a view, like this;
<div ng-repeat="n in Model">
<div marked="n"></div>
</div>
or
<div marked>
<div ng-repeat="n in Model">
{{n}}
</div>
</div>
I just get {{n}} as the output, verbatim. Marked never runs, never does anything to it. I'm completely baffled. I know the text is fine.
I have tried all of the examples and nothing seems to work. It does work if I put in static, hard-coded text between <marked> directives - but nothing dynamic.
The only way I've been able to make anything work is to forcefully use the marked(n) function within the controller - which is far less than ideal and certainly not what I'm wanting to do.
After a lot of trying, I think that the way angular-ui-router is involved may play a part. Here is the HTML structure;
index.html
<div class="content-body">
<ui-view />
</div>
content.html
<ui-view />
entry.html
<div ng-repeat="m in model">
<div marked="m"></div>
</div>
I think I've got it.
<div ng-repeat="m in model">
<div marked="m"></div>
</div>
Works as per this fiddle: https://jsfiddle.net/jorgthuijls/q244srfh/
See, ng-repeat creates its own scope. So, you can bind the m variable to the marked directive.
I got it to work with angular-ui-router too: https://jsfiddle.net/jorgthuijls/ck8by0ze/
I've got this template:
<div class="container-fluid">
<div class="row">
<div class="col-xs-12" ng-repeat="product in ad.products">
<a href="{{product.link}}">
<h1>{{product.title}}</h1>
<img src="{{product.src}}">
<p>{{product.description}}</p>
<h5>{{product.price}}</h5>
</a>
</div>
</div>
</div>
From my controller I need to evaluate this template so that it checks how many products that have been selected and then it interpolates each product's values into the template. After that is done I also need to remove the ng-repeat so it doesn't fire an error in the external pages that will use this where angular is not present. However I'd figure that I'd just use a regex to look up the ng-repeat and everything in the expression and then remove it.
I've been looking at $interpolate and $compile but I can't figure out how to work with them from my controller so that it does what I want. This is because when I use these on my template and then console log the template value it's a function with a whole lot of nonsense in it.
So doing this:
ad.html = $compile(res.data, $scope);
Generates something like this:
function(b,c,d){rb(b,"scope");e&&e.needsNewScope&&(b=b.$parent.$new());d=d||{};var h=d.parentBoundTranscludeFn,k=d.transcludeControllers;d=d.futureParentElement;h&&h.$$boundTransclude&&(h=h.$$boundTr…
Can someone shed some light on how to achieve what I want?
Your are using $compile function in wrong way, you should call $compile(html) function by passing $scope parameter like below.
var compiledDOM = $compile(res.data)($scope);//then do append this DOM to wherever you want
ad.html = compiledDOM.html(); //but this HTML would not make angular binding working.
I'm trying to do a very simple thing. I'm displaying a list of values with Edit links beside them. Clicking the edit link reveals a form that lets you update the value.
(I've simplified the question so the items just have one field "name". My actual use case has more fields, but is canonically equivalent.)
I've run into something that looks like a bug in Angular, but given my limited experience with it, I'm not so sure. Here's how I'm trying to do it:
<div ng-repeat-start="item in items" ng-controller="ItemCtrl as ctrl" ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-repeat-end ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
My controller looks like this:
app.controller('ItemController', function() {
this.isEditing = false;
this.startEditing = function() { this.isEditing = true; }
this.save = function() { this.isEditing = false; }
});
Clicking on Edit link calls the right controller function, and the first div hides. But the second div does not hide.
When I rearrange the code to look like this (essentially wrapping the two divs with a wrapper element), all is well.
<div ng-repeat="item in items" ng-controller="ItemCtrl as ctrl">
<div ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
</div>
Any idea what is technically wrong with the first version? Note that the <input> boxes do get populated with the right values from item.name.
PS: There's a reason why I'm trying to keep the two divs siblings: in my use case, they are actually implemented as two trs which are supposed to appear right below each other in a table.
It's not a bug from angular but it is quite logical.
<div ng-repeat-start="item in items" ng-controller="ItemCtrl as ctrl" ng-hide="ctrl.isEditing">
<span>Name: {{item.name}}.</span>
<a href='#' ng-click='ctrl.startEditing()'>Edit</a>
</div>
<div ng-repeat-end ng-show="ctrl.isEditing">
<input type='text' ng-model='item.name'/>
<a href='#' ng-click='ctrl.save()'>Save</a>
</div>
If you see the above code you have injected controller only to the first div so obviously sibling div doesn't know what is ctrl or ItemCtrl until and unless you do as in you second way.
So if you want to achieve it as sibling, if you are using routing then add the controller attribute in your route path.
So that the controller will be active for that entire template and you can achieve what you want.
Hope it helps.
Thats because controller has its own scope. When you placed controller ONLY on your first div controllers' scope is limited to only this one div. When you wrapped both your divs inside another and place controller on wrapper, controllers' scope now is all that inside this wrapper. So in this case this works fine and this is not the angular bug
I want to have a login view outside ng-view, but is it even possible with angular.js? couldnt find any examples of folowing on the internet. Example is descibed below.
<div class="container">
<div class="header">
<div class="loginView"> my huge login view</div>
</div>
</div>
<div class="container">
<div ng-view></div>
</div>
Yes. Assign a controller to the loginView and treat it like any other view.
ng-view is just used when using the $routeProvider to define routes.
This is perfectly valid. ngView is used to complement the router. This means it is just a directive as any other. You can put anything around it.
It sounds like you want something like this: Live demo here (click).
<div class="container">
<div class="header">
<div class="loginView" ng-include="'login.html'"></div>
</div>
</div>
You could also include your file from a $scope property like this:
$scope.foo = 'login.html';
<div ng-include="foo"></div>
I have a directive by name cngView
controller.js
//directive to include view panel
angular.module('cngFoundation', [])
.directive('cngView', function() {
return {
restrict : 'CAME',
templateUrl: 'templates/view.html'
};
});
to access directive
<div ng-app="cngFoundation">
<div id="mainbody" class="container">
<cng-view>
[AAA]
</cng-view>
</div>
</div>
The templates/view.html is as follows
<!-- View Panel-->
<div class="panel panel-primary " id="view" >
<div class="panel-heading">
<h3 class="panel-title" ><b>View</b></h3>
</div>
<div class="panel-body">
[BBB]
</div>
</div>
I have made the cng-view tag work but I don't know how to give contents inside the tag.
How to make contents I give at place "[AAA]" appear at "[BBB]" .
In short how to make contents I give within cng-view tag(a custom tag) go into the specific place inside the template content of the cng-view .
Please give guidance . At least please direct me to some online tutorial .
Thanks
You need to use ng-transclude which tells template where to place existing content
<div class="panel-body" ng-transclude></div>
Also need to set transclude:true in directive
See section Creating a Directive that Wraps Other Elements in directive docs
You can use the built in ng-transclude directive. In your view.html replace [BBB] with
<span ng-transclude></span>
also be sure to define transclude on your directive
transclude: true,
