问题
I am new to AngularJS and I've been unable to find specific tutorials of a list and grid view toggle switch buttons that loads in two different HTML partials. Read official ng-include, ng-switch official docs and searched SO. Unfortunately, we don't want to use UI-router.
Is loading in two partials (list.html and grid.html) the correct Angular way of coding this?
The most relevant help I've found are these:
1.http://tutorialzine.com/2013/08/learn-angularjs-5-examples (Example #5)
There was an insightful comment on Example #5
Nice simple examples - well done. The last example that switches between grid and list views is not very efficient since it creates both options and the shows/hides one. A simpler/better approach would be using a single ul with repeater and ng-switch and then enabling the alternate list elements using ng-switch-case. - Johan

3.create a single html view for multiple partial views in angularjs
4.Conditional ng-include in angularjs
My HTML code
<div class="col-xs-6" ng-controller="ToggleDisplayCtrl">
<div class="btn-group select-format-container" ng-switch on="selected">
<button ng-switch-when="true" ng-click="toggleGrid()" type="button" class="btn btn-primary" ng-model="formatChoice" ng-disabled="">grid</button>
<button ng-switch-when="false" ng-click="toggleList()" type="button" class="btn btn-primary" ng-model="formatChoice" ng-disabled="">list</button>
</div>
<div ng-include src="formatChoice.url" scope="" onload=""></div>
</div><!-- col-xs-6 END ToggleDisplayCtrl-->
My directive code
'use strict';
var app = angular.module('tempApp');
app.controller('ToggleDisplayCtrl', function($scope) {
$scope.formatChoices =
[ { name: 'grid', url: 'partials/grid.html'},
{ name: 'list', url: 'partials/list.html'} ];
$scope.selected = true;
$scope.toggleGrid = function() {
if(selected) {
return "partials/grid.html";
}
return "main.html";
};
$scope.toggleList = function() {
if(selected) {
return "partials/list.html";
}
return "main.html";
};
});

You should define application controller's scope property that will hold URL of template for ng-include, and bind this property to your directive's scope. Make sure to use isolated scope in your directive in order to avoid side effects while modifying directive's scope. Here is an example of doing it (see comments in the code):
JavaScript
angular.module('app',['ngRoute']).
config(['$routeProvider', function($routeProvider){
$routeProvider.
when('/main', {
controller: 'appController',
templateUrl: 'main.html'
}).
otherwise({
redirectTo: '/main'
});
}]).
controller('appController', ['$scope', function($scope){
$scope.view = 'list.html'; // <- default template used for ng-include
$scope.data = [{
text: '1'
}, {
text: '2'
}, {
text: '3'
}, {
text: '4'
}, {
text: '5'
}, {
text: '6'
}];
}]).
directive('appView', function() {
return {
scope: {
view: '=appView' // <= link view property of directive's scope to some property in the parent scope (scope of appController) specified in app-view attribute of root element of directive
},
replace: true,
template: '<nav class="navbar navbar-default">' +
'<div class="container">' +
'<ul class="nav navbar-nav navbar-right">' +
'<li ng-repeat="v in views" ng-bind="v.name" ng-class="v.icon" ng-click="switchView(v)"></li>' +
'</ul>' +
'</div>' +
'</nav>',
link: function(scope, el, attr) {
scope.views = [{
name: 'List',
template: 'list.html',
icon: 'btn btn-default navbar-btn glyphicon glyphicon-th-list'
}, {
name: 'Grid',
template: 'grid.html',
icon: 'btn btn-default navbar-btn glyphicon glyphicon-th'
}];
},
controller: ['$scope', function($scope){
$scope.switchView = function(view) {
$scope.view = view.template; // <- modify parent scope view
}
}]
}
});
Main page of application (index.html)
<html ng-app="app">
...
<body ng-view=""></body>
</html>
Route template(main.html)
<header app-view="view"></header>
<section ng-include="view"></section>
List view template (list.html)
<div class="container">
<div class="row">
<div class="col-md-12 col-sm-12 panel panel-default" ng-repeat="item in data">
<div class="panel-body">{{item.text}}</div>
</div>
</div>
</div>
Grid view template (grid.html)
<div class="container">
<div class="row">
<div class="col-md-4 col-sm-6 panel panel-default" ng-repeat="item in data">
<div class="panel-body">{{item.text}}</div>
</div>
</div>
</div>

Bonus: grid is responsive, just play a bit with a window size
Another Option:
As you have probably noticed, grid.html and list.html are very similar, so if you have only these two options you may decide not to use ng-include with separate switchable views at all, but place content view directly into your route's template and just switch classes used in panels using ng-class directive which can switch classes when view is changed.
Route template(main.html)
<header app-view="view"></header>
<section>
<div class="container">
<div class="row">
<div ng-class="{'col-md-4': view === 'grid.html', 'col-md-12': view === 'list.html', 'panel':true, 'panel-default':true}" ng-repeat="item in data">
<div class="panel-body">{{item.text}}</div>
</div>
</div>
</div>
</section>

Here's a simple working JSBin: http://jsbin.com/jomiquqi/1/edit
The ng-include directive takes a variable for the template to include. So to update your code to get it working, your toggleGrid() method shouldn't be returning something, it should be setting a variable on the scope which you pass to ng-include like in my example.

Basically what you need to do is put a list view and grid same time on the same page and display one at a time, toggling between them(changing css class) with the switch button.I'll discuss the Example #5 here:
First layout variable in the scope
$scope.layout = 'grid';
Here are the switch buttons
<!-- On click change "$scope.layout = list" and if layout=='list' add class 'active' to self-->
<a href="#" class="list-icon" ng-class="{active: layout == 'list'}" ng-click="layout = 'list'"></a>
<!-- On click change "$scope.layout = grid" and if layout=='grid' add class 'active' to self-->
<a href="#" class="grid-icon" ng-class="{active: layout == 'grid'}" ng-click="layout = 'grid'"></a>
These are the grid and list blocks.
<!-- Layout=='grid' if layout parameter is grid than show this block -->
<ul ng-show="layout == 'grid'" class="grid">...</ul>
<!-- Layout=='list' if layout parameter is list than show this block -->
<ul ng-show="layout == 'list'" class="list">...</ul>
Css that makes the list and grid layout
/*-------------------------
List layout
--------------------------*/
ul.list{
list-style: none;
width: 500px;
margin: 0 auto;
text-align: left;
}
ul.list li{
border-bottom: 1px solid #ddd;
padding: 10px;
overflow: hidden;
}
ul.list li img{
width:120px;
height:120px;
float:left;
border:none;
}
ul.list li p{
margin-left: 135px;
font-weight: bold;
color:#6e7a7f;
}
/*-------------------------
Grid layout
--------------------------*/
ul.grid{
list-style: none;
width: 570px;
margin: 0 auto;
text-align: left;
}
ul.grid li{
padding: 2px;
float:left;
}
ul.grid li img{
width:280px;
height:280px;
display:block;
border:none;
}

The easiest way to do this is:
<div class = "bar">
<h1>Contacts</h1>
<a href="#" class="list-icon" ng-class="{active: layout == 'list'}" ng-click="layout = 'list'"></a>
<a href="#" class="grid-icon" ng-class="{active: layout == 'grid'}" ng-click="layout = 'grid'"></a>
</div>
<div ng-show="layout == 'list'" class="list">
//Add your list page here
<div ng-show="layout == 'grid'" class="grid">
//Add your grid page here
CSS:
/*
Contacts bar with toggle switches
*/
.bar{
background-color: #5c9bb7;
background-size: 100% 100%;
box-shadow: 0 1px 1px #ccc;
border-radius: 2px;
height: 100px;
padding: 10px;
position: relative;
text-align: right;
line-height: 1;
}
.bar a{
background:#4987a1 center center no-repeat;
width:32px;
height:32px;
display:inline-block;
text-decoration:none !important;
margin-right:5px;
border-radius:2px;
}

For better understanding of toggling action to see the list and grid view: follow this link and I hope this is helpful.
In this we used Jquery, if you are experimenting on this. Do place this:
