I have a page with two tabs and in one of them I have a clickable component that is supposed to change a scope attribute that represents a class. The class content changes is working fine but it is not applying the effect of the class, just when I switch from this tab to another one and come back. Then, when I switch back it applies the CSS class changes.
<!-- Element 1 -->
<div ng-class="{ '{{scopeAttibute}}': true }">
content
</div>
<!-- Element 2 -->
<div ng-click="scopeAttibute=localAttrubute">
content
</div>
I solved it replacing the ng-class for id and the classes for IDs in my CSS style. Like this:
<div id="{{scopeAttibute}}">
content
</div>
<!-- Element 2 -->
<div ng-click="scopeAttibute=localAttrubute">
content
</div>
First you have to set scopeAttribute = true
<!-- Element 1 -->
<div ng-class="{'scopeAttibute': scopeAttibute == true}">
content
</div>

I need a way to hide a parent element if the element inside of it is empty using AngularJS.
Would this be a custom directive type issue or is there a way to put the logic into something like ng-show or ng-hide?
<div class="item"> <!-- item should be hidden -->
<div class="inside"></div>
</div>
I would assume the inside div would have some data from the scope displayed? If the data is an empty string of null, then you can check that with ng-hide in the parent. Something like the below perhaps?
<div ng-hide='myData == null' class="item"> <!-- item should be hidden -->
<div class="inside">{{myData}}</div>
</div>
I am new to AngularJS and I have seen others asking similar questions, but the answers are not working for me. Rather than hijacking those questions, I thought I would open one for myself.
I am creating a demo app -- it lists "sites" which can be added to or deleted. I am using the ng-show attribute to display the required html div while hiding the others.
Here is the back-end javascript--
var SiteMaintenanceModule = angular.module("SitesMaintenance", []);
SiteMaintenanceModule.controller("siteCtrl", diveSiteCtrlfn);
function diveSiteCtrlfn($scope) {
// initializing the sites array
$scope.sites = sites;
//initializing the Divs array
$scope.allowedDivs = ["listSiteDiv","addSiteDiv", "editSiteDiv","deleteSiteDiv"];
// setting the first div as selected. This should show the div which lists the sites
$scope.selectedDiv = $scope.allowedDivs[0];
// function to be called with the selected div is to be changed
$scope.setSelectedDiv = function ($divSelectedByUser) {
$scope.selectedDiv = $divSelectedByUser;
}
};
And here is the html
<html xmlns="http://www.w3.org/1999/xhtml" ng-app="SitesMaintenance">
<head>
<title>List of Dive Sites</title>
<link rel="Stylesheet" href="./../zHelpers/bootstrap/css/bootstrap.css" />
<script src="./../zHelpers/angular.min.js"></script>
<script src="./sites.js"></script>
<script src="./SiteMaintenance.js"></script>
</head>
<body ng-controller="siteCtrl">
<!-- Display the list of sites based on the selectedDiv variable-->
<div id="SiteList" ng-show="{{selectedDiv == 'listSiteDiv'}}">
<h3>List of Sites</h3>
<ul ng-repeat="site in sites" ng-model="sites">
<li>{{site.site}} in {{site.location}}</li>
</ul>
</div>
<!-- Display the add site Div based on the selectedDiv variable-->
<div id="AddSite" ng-show="{{selectedDiv == 'addSiteDiv'}}">
<h3>Add New Site</h3>
<div style="display:block; margin:10px">Site: <input id="inputAddSiteName" /></div>
<div style="display:block; margin:10px">Location: <input id="inputAddSiteLocation" /></div>
</div>
<!-- Display the edit site Div based on the selectedDiv variable -->
<div id="EditSites" ng-show="{{selectedDiv == 'editSiteDiv'}}" style="display:block;margin:20px">
Site Name:<input id="InputEditSiteName" />
Site Location:<input id="InputEditSiteLocation" />
</div>
<div id="controls">
<button id="AddNewSiteButton" ng-click="setSelectedDiv('addSiteDiv')">Add Site</button>
<button id="DeleteSiteButton" ng-click="setSelectedDiv('deleteSiteDiv')">Delete Site</button>
<button id="EditSiteButton" ng-click="setSelectedDiv('editSiteDiv')">Edit Site</button>
</div>
</body>
I can set the visible div to whatever I want at the start, by changing the index in the statement "$scope.selectedDiv = $scope.allowedDivs[0];" in the JavaScript.
I change the value of $scope.selectedDiv when any of the buttons on the page are clicked, so as to change the visibility of the divs.
However, the visibility of the divs doesn't change, no matter what the value of $scope.selectedDiv is. In fact, when debugging in chrome, I see that the attribute value of ng-show for each of my divs updates dynamically to "true" or "false" and expected, but the div is still displayed -- the initially invisible divs seems to have a class="ng-hide" attribute, which never changes.
I have tried $scope.$apply() in the JavaScript but that gives errors. Any help would be greatly appreciated.
You don't need to use {{}} interpolation inside ng-show directive directive, it evaluates the expression inside a $scope of your controller directly.
ng-show="selectedDiv == 'addSiteDiv'"
ng-show="selectedDiv == 'listSiteDiv'"
ng-show="selectedDiv == 'editSiteDiv'"
I'm trying to build a directive which will display a kendo window with a kendo tab strip in its body content.
It's a component I need to be reusable since I use it a lot in my web app.
Here is the flat html representation that I want to turn into a directive
<div style="padding:20px;" kendo-window="test" id="test" k-title="hello" k-options="popupOptions">
<div kendo-tab-strip k-content-urls="[ null, null]">
<!-- tab list -->
<ul>
<li class="k-state-active">View</li>
<li>Edit</li>
</ul>
<div style="padding: 1em">
This is the view tab
</div>
<div style="padding: 1em">
This is the edit tab
</div>
</div>
</div>
1) First step is creating the directive that wraps the kendo popup and this si where I'm having an issue
So basically, my directive includes the kendo-window widget in its template and has transclude="true", since the content of the popup will different each time.
It seems "transclude" and "scope" cause some issues.

I'm running into a very odd situation trying to display a simple scope variable inside an angularjs template. Here's the simplified template code:
<div id="Parent" data-ng-controller="MyController">
{{ScopeVariable}} <!-- Diplays Just Fine -->
<div>
... Some Buttons ...
{{ScopeVariable}} <!-- Here it displays as {{ScopeVariable}}. Why? -->
</div>
<div ng-repeat="SomeElement in SomeScopeArray">
{{ScopeVariable}} <!-- Diplays Just Fine -->
</div>
</div>
The same single scope variable displays correctly inside the controller element as well as a repeated div. But if I try to display it inside a simple div, it fails.
I have used the example from Angular JS Homepage and modified it to meet the requirements.
I have added the tabs info in a scope array and manipulate the data based in some conditions.
Issues:
I have attached an ng-bind on tabItem.title, so any change in the text box will update the title, but i want to limit the displaying of the title by 10 chars
When i create a new tab, i want that tab to be the selected one.
How can i select a tab based on some action taken (like on a click move from tab 1 to tab 2)

<div ng-cloak ng-app="TabsApp">

<div tabs>
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title }}">

that's strange...
The limitTo filter doesn't seem to work, but you can create a new one and change your line
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title }}">
by
<div ng-repeat="tabInfo in tabManager.tabItems" pane title="{{ tabInfo.title | limit:10}}">
with
angularApp.filter('limit', function() {
return function (input, value) {
return input.substr(0,value);
};
});
For the select one, I think it doesn't work because you have to have access to the pane scope. One way to do it is to access to access the property from the pane when you create it. In the pane directive, just add :
if(scope.$parent.tabInfo.selected) tabsCtrl.select(scope);
just after the tabsCtrl.addPane(scope); line. But then you also have to change the tabs directive so that the line
$scope.select = function(pane) {
become
this.select = $scope.select = function(pane) {
For your 3rd question, I don't know how to do it in that scheme.
I would make the pane directive different, putting the select function out of the directive, and binding it directly to your tabManager object.
Like this : http://jsfiddle.net/NWwcT/2/
In this cas, you have the 3 requirements, and you can select the tab from ouside by calling tabManager.select(index)
