How to hide a div with angular js ng-hide - javascript

I have a page with a div which contains a jumbotron, this is the first page that is display anytime the site is accessed. On this page I have some links which link to different pages using the '$routeProvide'/angular. I want to hide the jumbotron from the other links/pages but I am not sure how to do that.
main page :
<body ng-app="single-page-app">
<div ng-controller="cfgController">
<div>
<nav class="navbar navbar-default" role="navigation">
<div class="container">
<div class="navbar-header col-md-12 col-sm-12 logo">

here is my script.js
var app=angular.module('single-page-app',['ngRoute']);
app.config(function($routeProvider){
$routeProvider
.when('/index',{
templateUrl: 'index.html'
})
.when('/about',{
templateUrl: 'about.html'

templateUrl: 'advService.html'

});
app.controller('cfgController'['$Scope', function($scope) {
$Scope.hideme = false;
$Scope.$on('$locationChangeStart', function(event) {
$scope.hideme = true;
});
}]);
here is a typical link to a different page about.html :
<div class="container-fluid col-md-12 about-us">
<div class="about-us col-md-offset-1">
<h2 class="col-md-10">
<span class="title2">About Us</span>
<div class="line"></div>
</h2>
<p class="col-md-10 article">text</p>
</div>
</div>

Is that really hard... So ng-hide is easy to use
To hide a div just do this :
<div ng-hide="hideme">your content </div>
and in your controller you define hideme variable like this :
$scope.hideme = true; // true to hide ,false to show
Edit: So in your case do this :
<li class="navlink"><a ng-click="hideIt()" href="#/about">About Us</a></li>
In your controler make a fucntion hideIt to hide the jumbotron div :
$scope.hideIt = function(){
$scope.hideme = true;
}

app.run(['$rootScope', function($rootScope) {
$rootScope.hideme = false;
$rootScope.$on('$routeChangeStart', function(){
$rootScope.hideme = true;
});
Along with your code, just add this run block. It should work.

How to hide panel and navbar in login page framework7

I'd like to hide correctly the panel and the navbar only in the login page. After login I'd like to show them. I achieve this task partially, because my code has a bad side effect. When I open the app I saw my login page but for few second the navbar appears and then disappears. I'd like to access on login page without this effect. I'd like to see immediatly the login page without them.
How can I solve it?
I declared them in my index.html
<div id="app">
<div class="panel panel-left panel-cover">

This is my config file app.js where I show and hide the elements on pageInitEvent
var $$ = Dom7;
var app = new Framework7({
// App root element
root: '#app',
// App Name
name: 'myApp',
// App id
id: 'it.myapp.myApp',

},
{

path: '/login/',
url: './pages/login.html',
on:{
pageInit: function(){
app.navbar.hide('.navbar');

}
And finally this is my login.html page where I put no-navbar in orderd to hide it.

Best thing is hide navbar before init or while its mounted
You can try these two
1:Beforeinit
{
name: 'login',
path: '/login/',
url: './pages/login.html',
on:{
pageBeforeIn: function(){
app.navbar.hide('.navbar');
}
},
}
2:When its injected to DOM an
{
name: 'login',
path: '/login/',
url: './pages/login.html',
on:{
pageMounted: function(){
app.navbar.hide('.navbar');
}
},
}
pageInit will be triggered once required components and navbar is loaded
you can hide the panel in the login page using pageInit event
pageInit : function (e,p) { p.app.panel.left.hide() }

Phonegap and Framework7, add external JavaScript files for specific pages

I would like to add external Javascript files, for specific pages in my Phonegap app. The app uses Framework7 for the UI.
Example:
Exercise page 2.1 has JavaScript file exercise2_1.js.
Exercise page 2.9 has JavaScript file exercise2_9.js ect.
I only want to load the JavaScript files, when the user is on that specific page.
The JavaScript files work, when they are included in the header section on the index page. I don't want to load all the exercise JavaScript files. I only want to load the one's being used. Is it possible to do this, without loading all the js files?
In the my-app section, i tried to load the files as an external js file. But could not get it to work. Nothing happens.

</div>
</div>
</div>
I accomplished this by including JQuery and doing the following:
$$(document).on('pageInit', function (e) {
var page = e.detail.page;
if (page.name == 'page1') {
$.getScript("js/page1.js");
} else if (page.name == 'page2') {
$.getScript("js/page2.js");
}
});
I found the problem. It had to do with the onload event on the index page.
I removed the onload event from the index page and put it in the exercise page.
This solved my issue.
<iframe style="display:none" onload="StartUp()" id="TheBody" src="js/exercise2_1.js"></iframe>
Hopes this helps someone else.

How to display sidebar content using angular ui-router?

On home page i have sidebar and Main content , when i click on sidebar items i want to display sidebar content to right side where i have Main content. I want fixed sidebar on all the pages only main content should change and rendered data based on states. How can i achieve that task using angularjs routing ?
home.html
<div class="row">
<div class="col s3">
<div>
<ul>
<li ui-sref="desktop"> Desktop</li>
<li ui-sref="laptop"> Laptops</li>
<li ui-sref="monitor"> Monitors</li>
</ul>
</div>
</div>
<div class="col s9">
<h1>Main Content</h1>
</div>
</div>
routes.js
angular.module('computerTrading').config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'views/home.html',
controller: 'MainController'
})
.state('contact',{
url:'/contact',
templateUrl:'views/contact.html',
controller:'ContactController'
}).
state('inventory',{
url:'/inventory',
templateUrl:'views/inventory.html',
controller:'InventoryController'
}).
state('laptop',{
templateUrl:'views/laptop.html',
controller:'LaptopController'
})
.
state('desktop',{
templateUrl:'views/desktop.html',
controller:'DesktopController'
})
.
state('monitor',{
templateUrl:'views/monitor.html',
controller:'MonitorController'
});
});
You will need a ui-directive at your col s9 part:
<div class="row">
<div class="col s3">
<div>
<ul>
<li ui-sref="desktop"> Desktop</li>
<li ui-sref="laptop"> Laptops</li>
<li ui-sref="monitor"> Monitors</li>
</ul>
</div>
</div>
<div class="col s9">
<h1>Main Content</h1>
<div ui-view></div><!--you need this-->
</div>
</div>

Angular.js Model-View-Controller Dynamic Updates Not Working

AngularJS v1.2.0rc1
I have setup an angular Model-View-Controller. It is accurately requesting data from my database and displaying the values on the html page. However, the problem I am having is when the data I am requesting changes from the current value being displayed, it is not updating the html view.
Code
Controller
var API_ORDER_ROUTE = '/api/stats';
function feedingStatsCtrl($http, $scope) {
$http.get(API_ORDER_ROUTE).success(function(data, status, headers, config) {
if (data.error) {
$scope.error = data.error;
} else {
$scope.current = data.current;
$scope.average = data.average.toFixed(2);
$scope.days_left = data.days_left ? data.days_left : 0;
$scope.days_remaining = Math.min($scope.days_left / 30 * 100.0, 100);
} // EOF else
}).error(function(data, status, headers, config) {
$scope.error = "Error fetching order statistics.";
});
}

I know the data is being requested properly. When I refresh the browser it correctly updates the three variables I am pulling from the DB. I just can't figure out why the Angular controller is not dynamically updating. Can any provide some guidance?
You may make a common mistake: try to refer a primitive variable from parent scope, in Angular, child scope can not refer a primitive type variable defined in parent scope (string, number, bool...etc), any primitive reference would create a separate variable in child scope with same value. So even $scope.current changed in parent scope, the variable in child scope won't change.
further reading about scope
You can use object to avoid this happened:
var API_ORDER_ROUTE = '/api/stats';
function feedingStatsCtrl($http, $scope) {
$scope.result = {};
$http.get(API_ORDER_ROUTE).success(function(data, status, headers, config) {
if (data.error) {
$scope.result.error = data.error;
} else {
$scope.result.current = data.current;
$scope.result.average = data.average.toFixed(2);
$scope.result.days_left = data.days_left ? data.days_left : 0;
$scope.result.days_remaining = Math.min($scope.days_left / 30 * 100.0,100);
} // EOF else
}).error(function(data, status, headers, config) {
$scope.result.error = "Error fetching order statistics.";
});
}
In template:
<div class="span8 offset2">
<div class="row-fluid statistics">
<div ng-show="!error">
<div class="span4">
<!-- linediv-l and linediv-r give dividing lines that look
different in horizontal and vertical layouts, illustrating

<div class="linediv-l">
<h3>{{result.current}}</h3> <p>Current</p>

<h3>{{result.days_left}}</h3> <p>Days Left</p>

Using html templates in angular's ng-switch

Im making an 'interactive menu' that moves along with user clicks.
Im wondering if there is a way to include html templates in ng-switch,
since all the logic is different in each 'switch' - it will result in huge html files.
<div class="content" ng-switch on="selection">
<div ng-switch-when="1" >
<h1>1</h1>
</div>
<div ng-switch-when="2">
<h1>2</h1>
</div>
</div>
Use ngInclude:
<div class="content" ng-switch on="selection">
<div ng-switch-when="1" >
<ng-include src="'template1.html'"></ng-include>
</div>
<div ng-switch-when="2">
<ng-include src="'template2.html'"></ng-include>
</div>
</div>
Note: Dont forget to use single quotes wrapped inside the double quotes if you are hard-coding the path.
You should be able to do it with ng-include directive :
<div class="content" ng-switch on="selection">
<ng-switch-when="1" ng-include="//TEMPLATE PATH">
<ng-switch-when="2" ng-include="//TEMPLATE 2 PATH">
</div>
**I used ng-Include this way.**
<!-- Main content -->
